+# Authorization System Implementation Summary
+
+## ✅ Implementation Complete
+
+A comprehensive polymorphic record sharing and authorization system has been implemented with CASL, Objection.js, and NestJS.
+
+## What Was Built
+
+### Backend (NestJS + Objection.js + CASL)
+
+#### 1. Database Layer
+- ✅ Migration for authorization tables (`20250128000001_add_authorization_system.js`)
+- ✅ Updated Prisma schema with new models
+- ✅ Objection.js models: `ObjectField`, `RoleRule`, `RecordShare`
+- ✅ Updated existing models with new relations
+
+#### 2. Authorization Core
+- ✅ `AbilityFactory` - Builds CASL abilities from 3 layers (global, role, share)
+- ✅ Query scoping utilities for SQL-level authorization
+- ✅ Guards and decorators (`AbilitiesGuard`, `@CheckAbility()`, `@CurrentUser()`)
+- ✅ Middleware for attaching abilities to requests
+
+#### 3. API Endpoints
+- ✅ **ShareController** - CRUD for record shares
+  - POST /shares - Create share
+  - GET /shares/record/:objectDefinitionId/:recordId - List shares
+  - GET /shares/granted - Shares granted by user
+  - GET /shares/received - Shares received by user
+  - PATCH /shares/:id - Update share
+  - DELETE /shares/:id - Revoke share
+
+- ✅ **RoleController** - Role management
+  - Standard CRUD for roles
+  - RoleRuleController for CASL rules
+
+- ✅ **ObjectAccessController** - Object-level permissions
+  - GET/PUT /setup/objects/:apiName/access
+  - POST /setup/objects/:apiName/fields/:fieldKey/permissions
+  - PUT /setup/objects/:apiName/field-permissions
+
+### Frontend (Nuxt 3 + Vue 3)
+
+#### 4. Object Management Enhancement
+- ✅ Added "Access & Permissions" tab to object setup page
+- ✅ `ObjectAccessSettings.vue` component:
+  - Configure access model (public/owner/mixed)
+  - Set public CRUD permissions
+  - Configure owner field
+  - Set field-level read/write permissions
+
+#### 5. Role Management
+- ✅ New page: `/setup/roles`
+- ✅ `RolePermissionsEditor.vue` component:
+  - Configure CRUD permissions per object
+  - Apply conditions (e.g., own records only)
+  - Visual permission matrix
+
+#### 6. Record Sharing
+- ✅ `RecordShareDialog.vue` component:
+  - List current shares
+  - Add new shares with permissions
+  - Field-level scoping
+  - Expiration dates
+  - Revoke shares
+
+## Key Features
+
+### 🌍 Global Object Policies
+- Public/private access models
+- Default CRUD permissions per object
+- Configurable owner field
+- Field-level default permissions
+
+### 👥 Role-Based Access
+- CASL rules stored in database
+- Per-object permissions
+- Condition-based rules (e.g., ownerId matching)
+- Multiple actions per rule
+
+### 🔗 Per-Record Sharing
+- Polymorphic design (works with any object type)
+- Grant read/update access to specific users
+- Optional field-level scoping
+- Expiration and revocation support
+- Track who granted each share
+
+### 🔒 SQL Query Scoping
+- Critical for list endpoints
+- Ensures users only see authorized records
+- Combines ownership + sharing logic
+- Works with public access flags
+

+
+## Next Steps
+
+### 1. Run the Migration
+```bash
+cd backend
+npm run migrate:latest
+```
+
+### 2. Initialize Existing Objects
+Set default access models for existing object definitions:
+```sql
+UPDATE object_definitions 
+SET 
+  access_model = 'owner',
+  public_read = false,
+  public_create = false,
+  public_update = false,
+  public_delete = false,
+  owner_field = 'ownerId'
+WHERE access_model IS NULL;
+```
+
+### 3. Apply Query Scoping
+Update existing controllers to use query scoping:
+
+```typescript
+import { applyReadScope } from '@/auth/query-scope.util';
+
+// In your list endpoint
+async findAll(@CurrentUser() user: User) {
+  const objectDef = await ObjectDefinition.query(this.knex)
+    .findOne({ apiName: 'YourObject' });
+  
+  let query = YourModel.query(this.knex);
+  query = applyReadScope(query, user, objectDef, this.knex);
+  
+  return query;
+}
+```
+
+### 4. Add Route Protection
+Use guards on sensitive endpoints:
+
+```typescript
+@UseGuards(JwtAuthGuard, AbilitiesGuard)
+@CheckAbility({ action: 'update', subject: 'Post' })
+async update(@Body() data: any) {
+  // Only users with 'update' permission on 'Post' can access
+}
+```
+
+### 5. Frontend Integration
+Add sharing button to record detail pages:
+
+```vue
+<template>
+  <div>
+    <!-- Your record details -->
+    <Button @click="showShareDialog = true">
+      <Share class="w-4 h-4 mr-2" />
+      Share
+    </Button>
+    
+    <RecordShareDialog
+      :open="showShareDialog"
+      :object-definition-id="objectDefinition.id"
+      :record-id="record.id"
+      :fields="objectDefinition.fields"
+      @close="showShareDialog = false"
+    />
+  </div>
+</template>
+```
+
+## Testing Checklist
+
+- [ ] Run database migration successfully
+- [ ] Create a test role with permissions
+- [ ] Configure object access settings via UI
+- [ ] Share a record with another user
+- [ ] Verify shared record appears in grantee's list
+- [ ] Verify query scoping filters unauthorized records
+- [ ] Test field-level permissions
+- [ ] Test share expiration
+- [ ] Test share revocation
+- [ ] Test role-based access with conditions
+
+## Performance Considerations
+
+1. **Index Usage**: The migration creates proper indexes on foreign keys and commonly queried columns
+2. **Query Scoping**: Uses SQL EXISTS subqueries for efficient filtering
+3. **Ability Caching**: Consider caching abilities per request (already done via middleware)
+4. **Batch Loading**: When checking multiple records, batch the share lookups
+
+## Security Notes
+
+⚠️ **Important**: Always use SQL query scoping for list endpoints. Never fetch all records and filter in application code.
+
+✅ **Best Practices**:
+- Share creation requires ownership verification
+- Only grantors can update/revoke shares
+- Expired/revoked shares are excluded from queries
+- Field-level permissions are enforced on write operations
+
+## Documentation
+
+Full documentation available in:
+- [AUTHORIZATION_SYSTEM.md](./AUTHORIZATION_SYSTEM.md) - Comprehensive guide
+- Inline code comments in all new files
+- JSDoc comments on key functions
+
+## Support
+
+For questions or issues:
+1. Check the documentation in `docs/AUTHORIZATION_SYSTEM.md`
+2. Review example usage in the controllers
+3. Examine the test cases (when added)

+# Tenant Migration & Admin Scripts
+
+This directory contains scripts for managing database migrations across all tenants and creating admin users in the multi-tenant platform.
+
+## Admin User Management
+
+### Create Central Admin User
+
+```bash
+npm run create-central-admin
+```
+
+Creates an administrator user in the **central database**. Central admins can:
+- Manage tenants (create, update, delete)
+- Access platform-wide administration features
+- View all tenant information
+- Manage tenant provisioning
+
+**Interactive Mode:**
+```bash
+npm run create-central-admin
+# You will be prompted for:
+# - Email
+# - Password
+# - First Name (optional)
+# - Last Name (optional)
+# - Role (admin or superadmin)
+```
+
+**Non-Interactive Mode (using environment variables):**
+```bash
+EMAIL=admin@example.com PASSWORD=securepass123 FIRST_NAME=John LAST_NAME=Doe ROLE=superadmin npm run create-central-admin
+```
+
+**Logging In as Central Admin:**
+1. Access the application using a central subdomain (e.g., `central.yourdomain.com` or `admin.yourdomain.com`)
+2. Enter your central admin credentials
+3. You'll be authenticated against the central database (not a tenant database)
+
+**Note:** The system automatically detects if you're logging in from a central subdomain based on the `CENTRAL_SUBDOMAINS` environment variable (defaults to `central,admin`). No special UI or configuration is needed on the frontend.
+
+### Create Tenant User
+
+For creating users within a specific tenant database, use:
+```bash
+npm run create-tenant-user <tenant-slug>
+# (Note: This script may need to be created or already exists)
+```
+
+## Migration Scripts
+
+### 1. Create a New Migration
+
+```bash
+npm run migrate:make <migration_name>
+```
+
+Creates a new migration file in `migrations/tenant/` directory.
+
+**Example:**
+```bash
+npm run migrate:make add_status_field_to_contacts
+```
+
+### 2. Migrate a Single Tenant
+
+```bash
+npm run migrate:tenant <tenant-slug-or-id>
+```
+
+Runs all pending migrations for a specific tenant. You can identify the tenant by its slug or ID.
+
+**Example:**
+```bash
+npm run migrate:tenant acme-corp
+npm run migrate:tenant cm5a1b2c3d4e5f6g7h8i9j0k
+```
+
+### 3. Migrate All Tenants
+
+```bash
+npm run migrate:all-tenants
+```
+
+Runs all pending migrations for **all active tenants** in the system. This is useful when:
+- You've created a new migration that needs to be applied to all tenants
+- You're updating the schema across the entire platform
+- You need to ensure all tenants are up to date
+
+**Output:**
+- Shows progress for each tenant
+- Lists which migrations were applied
+- Provides a summary at the end
+- Exits with error code if any tenant fails
+
+### 4. Rollback Migration (Manual)
+
+```bash
+npm run migrate:rollback
+```
+
+⚠️ **Warning:** This runs a rollback on the **default database** configured in `knexfile.js`. For tenant-specific rollbacks, you'll need to manually configure the connection.
+
+## Migration Flow
+
+### During New Tenant Provisioning
+
+When a new tenant is created via the API, migrations are automatically run as part of the provisioning process:
+
+1. Tenant database is created
+2. `TenantProvisioningService.runTenantMigrations()` is called
+3. All migrations in `migrations/tenant/` are executed
+
+### For Existing Tenants
+
+When you add a new migration file and need to apply it to existing tenants:
+
+1. Create the migration:
+   ```bash
+   npm run migrate:make add_new_feature
+   ```
+
+2. Edit the generated migration file in `migrations/tenant/`
+
+3. Test on a single tenant first:
+   ```bash
+   npm run migrate:tenant test-tenant
+   ```
+
+4. If successful, apply to all tenants:
+   ```bash
+   npm run migrate:all-tenants
+   ```
+
+## Migration Directory Structure

+```

+
+## Security Notes
+
+### Database Password Encryption
+
+Tenant database passwords are encrypted in the central database using AES-256-CBC encryption. The migration scripts automatically:
+
+1. Fetch tenant connection details from the central database
+2. Decrypt the database password using the `DB_ENCRYPTION_KEY` environment variable
+3. Connect to the tenant database
+4. Run migrations
+5. Close the connection
+
+**Required Environment Variable:**
+```bash
+DB_ENCRYPTION_KEY=your-32-character-secret-key!!
+```
+
+This key must match the key used by `TenantService` for encryption.
+
+## Troubleshooting
+
+### Migration Fails for One Tenant
+
+If `migrate:all-tenants` fails for a specific tenant:
+
+1. Check the error message in the output
+2. Investigate the tenant's database directly
+3. Fix the issue (manual SQL, data cleanup, etc.)
+4. Re-run migrations for that tenant: `npm run migrate:tenant <slug>`
+5. Once fixed, run `migrate:all-tenants` again to ensure others are updated
+
+### Migration Already Exists
+
+Knex tracks which migrations have been run in the `knex_migrations` table in each tenant database. If a migration was already applied, it will be skipped automatically.
+
+### Connection Issues
+
+If you see connection errors:
+
+1. Verify the central database is accessible
+2. Check that tenant database credentials are correct
+3. Ensure `DB_ENCRYPTION_KEY` matches the one used for encryption
+4. Verify the tenant's database server is running and accessible
+
+## Example Migration File
+
+```javascript
+// migrations/tenant/20250126000006_add_custom_fields.js
+
+exports.up = async function(knex) {
+  await knex.schema.table('field_definitions', (table) => {
+    table.boolean('is_custom').defaultTo(false);
+    table.string('custom_type', 50).nullable();
+  });
+};
+
+exports.down = async function(knex) {
+  await knex.schema.table('field_definitions', (table) => {
+    table.dropColumn('is_custom');
+    table.dropColumn('custom_type');
+  });
+};
+```
+
+## Best Practices
+
+1. **Always test on a single tenant first** before running migrations on all tenants
+2. **Include rollback logic** in your `down()` function
+3. **Use transactions** for complex multi-step migrations
+4. **Backup production databases** before running migrations
+5. **Monitor the output** when running `migrate:all-tenants` to catch any failures
+6. **Version control** your migration files
+7. **Document breaking changes** in migration comments
+8. **Consider data migrations** separately from schema migrations when dealing with large datasets
+
+## CI/CD Integration
+
+In your deployment pipeline, you can automatically migrate all tenants:
+
+```bash
+# After deploying new code
+npm run migrate:all-tenants
+```
+
+Or integrate it into your Docker deployment:
+
+```dockerfile
+# In your Dockerfile or docker-compose.yml
+CMD npm run migrate:all-tenants && npm run start:prod
+```

+# Polymorphic Record Sharing + Authorization System
+
+This document describes the implementation of a comprehensive authorization system using CASL, Objection.js, and NestJS.
+
+## Overview
+
+The system supports:
+- **Global object policies** - Public/private access, default permissions per object type
+- **Role-based access** - Permissions assigned to roles, with CASL rule storage
+- **Per-record sharing** - Polymorphic sharing where owners can grant specific users access to individual records
+- **Field-level permissions** - Fine-grained control over which fields can be read/written
+
+## Architecture
+
+### Database Schema
+
+#### `object_definitions` (Enhanced)
+- `accessModel`: 'public' | 'owner' | 'mixed'
+- `publicRead/Create/Update/Delete`: Boolean flags for public access
+- `ownerField`: Field name storing record owner (default: 'ownerId')
+
+#### `field_definitions` (Enhanced)
+- `defaultReadable`: Boolean - Can this field be read by default
+- `defaultWritable`: Boolean - Can this field be written by default
+
+These permission flags are added directly to the existing `field_definitions` table, keeping all field metadata in one place.
+
+#### `role_rules` (New)
+- `roleId`: FK to roles
+- `rulesJson`: JSON array of CASL rules
+
+#### `record_shares` (New)
+Polymorphic sharing table:
+- `objectDefinitionId`: FK to object_definitions
+- `recordId`: String (supports UUID/int)
+- `granteeUserId`: User receiving access
+- `grantedByUserId`: User granting access
+- `actions`: JSON array of actions ["read", "update", etc.]
+- `fields`: Optional JSON array of field names
+- `expiresAt/revokedAt`: Optional expiry and revocation timestamps
+
+### Backend Components
+
+#### AbilityFactory (`src/auth/ability.factory.ts`)
+Builds CASL abilities from three layers:
+1. **Global rules** - From object_definitions and object_fields
+2. **Role rules** - From role_rules.rulesJson
+3. **Share rules** - From record_shares for the user
+
+```typescript
+const ability = await abilityFactory.buildForUser(user, knex);
+if (ability.can('read', 'Post')) {
+  // User can read posts
+}
+```
+
+#### Query Scoping (`src/auth/query-scope.util.ts`)
+SQL-level filtering for list queries:
+
+```typescript
+import { applyReadScope } from '@/auth/query-scope.util';
+
+const query = Post.query(knex);
+applyReadScope(query, user, objectDefinition, knex);
+// Query now only returns records user can access
+```
+
+Logic:
+1. If `publicRead` is true → allow all
+2. Else → owner OR valid share exists
+
+#### Guards & Decorators
+- `AbilitiesGuard` - Checks CASL abilities on routes
+- `@CheckAbility()` - Decorator to require specific permissions
+- `@CurrentUser()` - Inject current user
+- `@CurrentAbility()` - Inject CASL ability
+
+#### Controllers
+
+**ShareController** (`src/rbac/share.controller.ts`)
+- `POST /shares` - Create a share
+- `GET /shares/record/:objectDefinitionId/:recordId` - List shares for a record
+- `GET /shares/granted` - List shares granted by current user
+- `GET /shares/received` - List shares received by current user
+- `PATCH /shares/:id` - Update a share
+- `DELETE /shares/:id` - Revoke a share
+
+**RoleController** (`src/rbac/role.controller.ts`)
+- Standard CRUD for roles
+- `RoleRuleController` manages CASL rules per role
+
+**ObjectAccessController** (`src/object/object-access.controller.ts`)
+- `GET /setup/objects/:apiName/access` - Get access config
+- `PUT /setup/objects/:apiName/access` - Update access model
+- `POST /setup/objects/:apiName/fields/:fieldKey/permissions` - Set field permissions
+- `PUT /setup/objects/:apiName/field-permissions` - Bulk update field permissions
+
+### Frontend Components
+
+#### ObjectAccessSettings (`components/ObjectAccessSettings.vue`)
+Integrated into object management page as "Access & Permissions" tab:
+- Configure access model (public/owner/mixed)
+- Set public CRUD permissions
+- Configure owner field
+- Set default read/write permissions per field
+
+#### RecordShareDialog (`components/RecordShareDialog.vue`)
+Dialog for sharing individual records:
+- List current shares
+- Add new share with user email
+- Select read/update permissions
+- Optional field-level scoping
+- Optional expiration date
+- Revoke shares
+
+#### Role Management (`pages/setup/roles.vue`)
+Complete role management interface:
+- List all roles
+- Create new roles
+- Delete roles
+- Edit role permissions
+
+#### RolePermissionsEditor (`components/RolePermissionsEditor.vue`)
+Granular permission editor:
+- Configure CRUD permissions per object type
+- Apply conditions (e.g., "ownerId = $userId")
+- Field-level restrictions (future)
+
+## Usage Examples
+
+### 1. Set Object to Owner-Only Access
+
+```typescript
+await api.put('/setup/objects/Post/access', {
+  accessModel: 'owner',
+  publicRead: false,
+  ownerField: 'ownerId'
+});
+```
+
+### 2. Share a Record
+
+```typescript
+await api.post('/shares', {
+  objectDefinitionId: 'abc-123',
+  recordId: 'post-456',
+  granteeUserId: 'user-789',
+  actions: ['read', 'update'],
+  fields: ['title', 'body'], // Optional field scoping
+  expiresAt: '2025-12-31T23:59:59Z' // Optional expiry
+});
+```
+
+### 3. Create Role with Permissions
+
+```typescript
+// Create role
+const role = await api.post('/roles', {
+  name: 'Account Manager',
+  description: 'Can manage accounts'
+});
+
+// Set permissions
+await api.post('/role-rules', {
+  roleId: role.id,
+  rulesJson: [
+    {
+      action: ['read', 'update'],
+      subject: 'Account',
+      conditions: { ownerId: '$userId' } // Only own accounts
+    },
+    {
+      action: ['read'],
+      subject: 'Contact' // Can read all contacts
+    }
+  ]
+});
+```
+
+### 4. Query with Authorization
+
+```typescript
+// In a controller
+async getRecords(user: User) {
+  const objectDef = await ObjectDefinition.query(this.knex)
+    .findOne({ apiName: 'Post' });
+  
+  const query = Post.query(this.knex);
+  applyReadScope(query, user, objectDef, this.knex);
+  
+  return query; // Only returns records user can read
+}
+```
+
+### 5. Check Instance Permission
+
+```typescript
+// With CASL
+const post = await Post.query().findById(id);
+if (ability.can('update', subject(post, 'Post'))) {
+  // User can update this post
+}
+```
+
+## Migration Guide
+
+1. **Run Migration**
+   ```bash
+   npm run migrate:latest
+   ```
+
+2. **Update Existing Objects**
+   Set default access model for existing object types:
+   ```sql
+   UPDATE object_definitions 
+   SET access_model = 'owner', 
+       owner_field = 'ownerId'
+   WHERE access_model IS NULL;
+   ```
+
+3. **Update Controllers**
+   Add query scoping to list endpoints:
+   ```typescript
+   import { applyReadScope } from '@/auth/query-scope.util';
+   
+   // Before
+   const records = await MyModel.query();
+   
+   // After
+   const records = await applyReadScope(
+     MyModel.query(),
+     user,
+     objectDef,
+     knex
+   );
+   ```
+
+4. **Add Guards**
+   Protect routes with ability checks:
+   ```typescript
+   @UseGuards(JwtAuthGuard, AbilitiesGuard)
+   @CheckAbility({ action: 'read', subject: 'Post' })
+   async findAll() {
+     // ...
+   }
+   ```
+
+## Security Considerations
+
+1. **Always use SQL scoping for lists** - Don't rely on post-fetch filtering
+2. **Validate share ownership** - Only grantor can update/revoke shares
+3. **Check expiry and revocation** - Filter out invalid shares in queries
+4. **Field-level filtering** - Strip unauthorized fields from request bodies
+5. **Tenant isolation** - All queries should be scoped to current tenant (if multi-tenant)
+
+## Testing
+
+### Unit Tests
+Test ability building:
+```typescript
+it('should allow owner to read their records', async () => {
+  const ability = await abilityFactory.buildForUser(user, knex);
+  const post = { id: '123', ownerId: user.id };
+  expect(ability.can('read', subject(post, 'Post'))).toBe(true);
+});
+```
+
+### Integration Tests
+Test query scoping:
+```typescript
+it('should only return owned records', async () => {
+  const query = Post.query(knex);
+  applyReadScope(query, user, objectDef, knex);
+  const records = await query;
+  
+  expect(records.every(r => r.ownerId === user.id)).toBe(true);
+});
+```
+
+## Future Enhancements
+
+- [ ] Group/team sharing (share with multiple users)
+- [ ] Public link sharing (token-based)
+- [ ] Audit log for shares
+- [ ] Share templates
+- [ ] Cascading shares (share related records)
+- [ ] Time-limited shares with auto-expiry
+- [ ] Share approval workflow
+- [ ] Delegation (share on behalf of another user)

+# Central Admin Authentication Guide
+
+## Overview
+
+The platform now supports **two types of authentication**:
+
+1. **Tenant Login** - Authenticates users against a specific tenant's database
+2. **Central Admin Login** - Authenticates administrators against the central platform database
+
+## Central vs Tenant Authentication
+
+### Tenant Authentication (Default)
+- Users login to their specific tenant database
+- Each tenant has isolated user tables
+- Access is scoped to the tenant's data
+- API Endpoint: `/api/auth/login`
+- Requires `x-tenant-id` header or subdomain detection
+
+### Central Admin Authentication
+- Administrators login to the central platform database
+- Can manage all tenants and platform-wide features
+- Users stored in the central database `users` table
+- API Endpoint: `/api/central/auth/login`
+- No tenant ID required
+
+## Creating a Central Admin User
+
+### Quick Start
+
+```bash
+cd backend
+npm run create-central-admin
+```
+
+Follow the interactive prompts to create your admin user.
+
+### Environment Variable Method
+
+```bash
+EMAIL=admin@platform.com \
+PASSWORD=SecureP@ssw0rd \
+FIRST_NAME=Admin \
+LAST_NAME=User \
+ROLE=superadmin \
+npm run create-central-admin
+```
+
+### Role Types
+
+- **admin** - Standard administrator with platform management access
+- **superadmin** - Super administrator with full platform access
+
+## Logging In as Central Admin
+
+### Frontend Login
+
+1. Navigate to the login page (`/login`)
+2. **Check the "Login as Central Admin" checkbox**
+3. Enter your central admin email and password
+4. Click "Login to Central"
+
+The checkbox toggles between:
+- ✅ **Checked** - Authenticates against central database
+- ⬜ **Unchecked** - Authenticates against tenant database (default)
+
+### API Login (Direct)
+
+**Central Admin Login:**
+```bash
+curl -X POST http://localhost:3000/api/central/auth/login \
+  -H "Content-Type: application/json" \
+  -d '{
+    "email": "admin@platform.com",
+    "password": "SecureP@ssw0rd"
+  }'
+```
+
+**Response:**
+```json
+{
+  "access_token": "eyJhbGciOiJIUzI1NiIs...",
+  "user": {
+    "id": "cm5a1b2c3d4e5f6g7h8i9j0k",
+    "email": "admin@platform.com",
+    "firstName": "Admin",
+    "lastName": "User",
+    "role": "superadmin",
+    "isCentralAdmin": true
+  }
+}
+```
+
+**Tenant Login (for comparison):**
+```bash
+curl -X POST http://localhost:3000/api/auth/login \
+  -H "Content-Type: application/json" \
+  -H "x-tenant-id: tenant1" \
+  -d '{
+    "email": "user@tenant1.com",
+    "password": "password123"
+  }'
+```
+
+## JWT Token Differences
+
+### Central Admin Token Payload
+```json
+{
+  "sub": "user-id",
+  "email": "admin@platform.com",
+  "isCentralAdmin": true,
+  "iat": 1234567890,
+  "exp": 1234654290
+}
+```
+
+### Tenant User Token Payload
+```json
+{
+  "sub": "user-id",
+  "email": "user@tenant1.com",
+  "iat": 1234567890,
+  "exp": 1234654290
+}
+```
+
+The `isCentralAdmin` flag in the JWT can be used to determine if the user is a central admin.
+
+## Database Schema
+
+### Central Database - `users` Table
+
+```sql
+CREATE TABLE users (
+  id VARCHAR(30) PRIMARY KEY,
+  email VARCHAR(255) UNIQUE NOT NULL,
+  password VARCHAR(255) NOT NULL,
+  firstName VARCHAR(100),
+  lastName VARCHAR(100),
+  role VARCHAR(50) DEFAULT 'admin',
+  isActive BOOLEAN DEFAULT true,
+  createdAt DATETIME DEFAULT CURRENT_TIMESTAMP,
+  updatedAt DATETIME DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
+);
+```
+
+### Tenant Database - `users` Table
+
+Tenant databases have their own separate `users` table with similar structure but tenant-specific users.
+
+## Security Considerations
+
+1. **Separate Password Storage** - Central admin passwords are stored separately from tenant user passwords
+2. **Role-Based Access** - Central admins have different permissions than tenant users
+3. **JWT Identification** - The `isCentralAdmin` flag helps identify admin users
+4. **Encryption** - All passwords are hashed using bcrypt with salt rounds
+
+## Common Use Cases
+
+### Platform Administration
+- **Login as:** Central Admin
+- **Can do:** 
+  - Create/manage tenants
+  - View all tenant information
+  - Manage platform-wide settings
+  - Access tenant provisioning APIs
+
+### Tenant Management
+- **Login as:** Tenant User
+- **Can do:**
+  - Access tenant-specific data
+  - Manage records within the tenant
+  - Use tenant applications
+  - Limited to tenant scope
+
+## Troubleshooting
+
+### "Tenant ID is required" Error
+- You're trying to login to tenant endpoint without tenant ID
+- Solution: Either provide `x-tenant-id` header or use central admin login
+
+### "Invalid credentials" with Central Login
+- Check that you're using the "Login as Central Admin" checkbox
+- Verify the user exists in the central database
+- Use the script to create a central admin if needed
+
+### "User already exists"
+- A central admin with that email already exists
+- Use a different email or reset the existing user's password

+# Central Admin Login
+
+## Overview
+
+The platform supports seamless authentication for both **tenant users** and **central administrators** using the same login endpoint. The system automatically determines which database to authenticate against based on the subdomain.
+
+## How It Works
+
+### Subdomain-Based Routing
+
+The authentication flow uses subdomain detection to determine the authentication context:
+
+1. **Central Subdomains** (e.g., `central.yourdomain.com`, `admin.yourdomain.com`)
+   - Authenticates against the **central database**
+   - Used for platform administrators
+   - Configured via `CENTRAL_SUBDOMAINS` environment variable
+
+2. **Tenant Subdomains** (e.g., `acme.yourdomain.com`, `client1.yourdomain.com`)
+   - Authenticates against the **tenant's database**
+   - Used for regular tenant users
+   - Each tenant has its own isolated database
+
+### Configuration
+
+Set the central subdomains in your `.env` file:
+
+```bash
+# Comma-separated list of subdomains that access the central database
+CENTRAL_SUBDOMAINS="central,admin"
+```
+
+### Implementation Details
+
+#### 1. Tenant Middleware (`tenant.middleware.ts`)
+
+The middleware extracts the subdomain from the request and:
+- Checks if it matches a central subdomain
+- If yes: Skips tenant resolution and attaches subdomain to request
+- If no: Resolves the tenant ID from the subdomain and attaches it to request
+
+#### 2. Auth Service (`auth.service.ts`)
+
+The auth service has branching logic in `validateUser()` and `register()`:
+- Checks if the subdomain is in the central list
+- Routes to `validateCentralUser()` or normal tenant user validation
+- Central users are authenticated against the `central` database
+- Tenant users are authenticated against their tenant's database
+
+#### 3. Auth Controller (`auth.controller.ts`)
+
+The controller:
+- Extracts subdomain from the request
+- Validates tenant ID requirement (not needed for central subdomains)
+- Passes subdomain to auth service for proper routing
+
+## Usage
+
+### Creating a Central Admin User
+
+```bash
+cd backend
+npm run create-central-admin
+```
+
+Follow the prompts to enter:
+- Email
+- Password
+- First Name (optional)
+- Last Name (optional)
+
+### Logging In as Central Admin
+
+1. Navigate to `central.yourdomain.com` (or whatever central subdomain you configured)
+2. Enter your central admin email and password
+3. You'll be authenticated against the central database
+
+**No special UI elements needed** - the system automatically detects the subdomain!
+
+### Logging In as Tenant User
+
+1. Navigate to `yourtenantslug.yourdomain.com`
+2. Enter your tenant user credentials
+3. You'll be authenticated against that tenant's database
+
+## Architecture Benefits
+
+✅ **Transparent to Frontend** - No need for special "login as admin" checkboxes or UI elements
+✅ **Secure** - Central and tenant authentication are completely separated
+✅ **Scalable** - Easy to add more central subdomains by updating environment variable
+✅ **Clean Code** - Single auth controller/service with clear branching logic
+✅ **Flexible** - Can be used for both development (localhost) and production
+
+## Local Development
+
+For local development, you can:
+
+1. **Use subdomain on localhost:**
+   ```
+   central.localhost:3000
+   acme.localhost:3000
+   ```
+
+2. **Use x-tenant-id header** (for tenant-specific requests):
+   ```bash
+   curl -H "x-tenant-id: acme-corp" http://localhost:3000/api/auth/login
+   ```
+
+3. **For central admin, use central subdomain:**
+   ```bash
+   curl http://central.localhost:3000/api/auth/login
+   ```
+
+## Database Schema
+
+### Central Database (`User` model)
+- Stores platform administrators
+- Prisma schema: `schema-central.prisma`
+- Fields: id, email, password, firstName, lastName, isActive, createdAt, updatedAt
+
+### Tenant Database (`users` table)
+- Stores tenant-specific users
+- Knex migrations: `migrations/tenant/`
+- Fields: id, email, password, firstName, lastName, isActive, created_at, updated_at
+
+## Security Considerations
+
+- Central admin credentials are never stored in tenant databases
+- Tenant user credentials are never stored in the central database
+- JWT tokens include user context (tenant ID or central admin flag)
+- Subdomain validation prevents unauthorized access

+# Custom Migrations Implementation
+
+## Overview
+
+This implementation adds a database-stored migration system for dynamically created objects. Migrations are recorded in a `custom_migrations` table in each tenant database, allowing them to be replayed or used for environment replication in the future.
+
+## Architecture
+
+### Components
+
+#### 1. CustomMigrationService
+**Location:** `backend/src/migration/custom-migration.service.ts`
+
+Handles all migration-related operations:
+
+- **`generateCreateTableSQL(tableName, fields)`** - Generates SQL for creating object tables with standard fields
+- **`createMigrationRecord()`** - Stores migration metadata in the database
+- **`executeMigration()`** - Executes a pending migration and updates its status
+- **`createAndExecuteMigration()`** - Creates and immediately executes a migration
+- **`getMigrations()`** - Retrieves migration history with filtering
+- **`ensureMigrationsTable()`** - Ensures the `custom_migrations` table exists
+
+#### 2. MigrationModule
+**Location:** `backend/src/migration/migration.module.ts`
+
+Provides the CustomMigrationService to other modules.
+
+#### 3. Updated ObjectService
+**Location:** `backend/src/object/object.service.ts`
+
+- Injects CustomMigrationService
+- Calls `createAndExecuteMigration()` when a new object is created
+- Generates table creation migrations with standard fields
+
+### Database Schema
+
+#### custom_migrations Table
+
+```sql
+CREATE TABLE custom_migrations (
+  id UUID PRIMARY KEY,
+  tenantId UUID NOT NULL,
+  name VARCHAR(255) NOT NULL,
+  description TEXT,
+  type ENUM('create_table', 'add_column', 'alter_column', 'add_index', 'drop_table', 'custom'),
+  sql TEXT NOT NULL,
+  status ENUM('pending', 'executed', 'failed') DEFAULT 'pending',
+  executedAt TIMESTAMP NULL,
+  error TEXT,
+  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+  updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
+  INDEX idx_tenantId (tenantId),
+  INDEX idx_status (status),
+  INDEX idx_created_at (created_at)
+)
+```
+
+#### Generated Object Tables
+
+When a new object is created (e.g., "Account"), a table is automatically created with:
+
+```sql
+CREATE TABLE accounts (
+  id VARCHAR(36) PRIMARY KEY,
+  ownerId VARCHAR(36),
+  name VARCHAR(255),
+  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+  updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
+  -- Custom fields added here
+)
+```
+
+**Standard Fields:**
+- `id` - UUID primary key
+- `ownerId` - User who owns the record
+- `name` - Primary name field
+- `created_at` - Record creation timestamp
+- `updated_at` - Record update timestamp
+
+### Field Type Mapping
+
+Custom fields are mapped to SQL column types:
+
+| Field Type | SQL Type | Notes |
+|---|---|---|
+| TEXT, STRING | VARCHAR(255) | |
+| LONG_TEXT | TEXT | Large text content |
+| NUMBER, DECIMAL | DECIMAL(18, 2) | |
+| INTEGER | INT | |
+| BOOLEAN | BOOLEAN | Defaults to FALSE |
+| DATE | DATE | |
+| DATE_TIME | DATETIME | |
+| EMAIL | VARCHAR(255) | |
+| URL | VARCHAR(2048) | |
+| PHONE | VARCHAR(20) | |
+| CURRENCY | DECIMAL(18, 2) | |
+| PERCENT | DECIMAL(5, 2) | |
+| PICKLIST, MULTI_PICKLIST | VARCHAR(255) | |
+| LOOKUP, BELONGS_TO | VARCHAR(36) | References foreign record ID |
+
+## Usage Flow
+
+### Creating a New Object
+
+1. **User creates object definition:**
+   ```
+   POST /api/objects
+   {
+     "apiName": "Account",
+     "label": "Account",
+     "description": "Customer account records"
+   }
+   ```
+
+2. **ObjectService.createObjectDefinition() executes:**
+   - Inserts object metadata into `object_definitions` table
+   - Generates create table SQL
+   - Creates migration record with status "pending"
+   - Executes migration immediately
+   - Updates migration status to "executed"
+   - Returns object definition
+
+3. **Result:**
+   - Object is now ready to use
+   - Table exists in database
+   - Migration history is recorded for future replication
+
+### Migration Execution Flow
+
+```
+createAndExecuteMigration()
+├── createMigrationRecord()
+│   └── Insert into custom_migrations (status: pending)
+└── executeMigration()
+    ├── Fetch migration record
+    ├── Execute SQL
+    ├── Update status: executed
+    └── Return migration record
+```
+
+## Error Handling
+
+Migrations track execution status and errors:
+
+- **Status: pending** - Not yet executed
+- **Status: executed** - Successfully completed
+- **Status: failed** - Error during execution
+
+Failed migrations are logged and stored with error details for debugging and retry:
+
+```typescript
+{
+  id: "uuid",
+  status: "failed",
+  error: "Syntax error in SQL...",
+  executedAt: null,
+  updated_at: "2025-12-24T11:00:00Z"
+}
+```
+
+## Future Functionality
+
+### Sandbox Environment Replication
+
+Stored migrations enable:
+
+1. **Cloning production environments** - Replay all migrations in new database
+2. **Data structure export/import** - Export migrations as SQL files
+3. **Audit trail** - Complete history of schema changes
+4. **Rollback capability** - Add down migrations for reverting changes
+5. **Dependency tracking** - Identify object dependencies from migrations
+
+### Planned Enhancements
+
+1. **Add down migrations** - Support undoing schema changes
+2. **Migration dependencies** - Track which migrations depend on others
+3. **Batch execution** - Run pending migrations together
+4. **Version control** - Track migration versions and changes
+5. **Manual migration creation** - API to create custom migrations
+6. **Migration status dashboard** - UI to view migration history
+
+## Integration Points
+
+### ObjectService
+
+- Uses `getTenantKnexById()` for tenant database connections
+- Calls CustomMigrationService after creating object definitions
+- Handles migration execution errors gracefully (logs but doesn't fail)
+
+### TenantDatabaseService
+
+- Provides database connections via `getTenantKnexById()`
+- Connections are cached with prefix `id:${tenantId}`
+
+### Module Dependencies
+
+```
+ObjectModule
+├── imports: [TenantModule, MigrationModule]
+└── providers: [ObjectService, CustomMigrationService, ...]
+
+MigrationModule
+├── imports: [TenantModule]
+└── providers: [CustomMigrationService]
+```
+
+## API Endpoints (Future)
+
+While not yet exposed via API, these operations could be added:
+
+```typescript
+// Get migration history
+GET /api/migrations?tenantId=xxx&status=executed
+
+// Get migration details
+GET /api/migrations/:id
+
+// Retry failed migration
+POST /api/migrations/:id/retry
+
+// Export migrations as SQL
+GET /api/migrations/export?tenantId=xxx
+
+// Create custom migration
+POST /api/migrations
+{
+  name: "add_field_to_accounts",
+  description: "Add phone_number field",
+  sql: "ALTER TABLE accounts ADD phone_number VARCHAR(20)"
+}
+```
+
+## Testing
+
+### Manual Testing Steps
+
+1. **Create a new object:**
+   ```bash
+   curl -X POST http://localhost:3000/api/objects \
+     -H "Authorization: Bearer <token>" \
+     -H "Content-Type: application/json" \
+     -d '{
+       "apiName": "TestObject",
+       "label": "Test Object",
+       "description": "Test object creation"
+     }'
+   ```
+
+2. **Verify table was created:**
+   ```bash
+   # In tenant database
+   SHOW TABLES LIKE 'test_objects';
+   DESCRIBE test_objects;
+   ```
+
+3. **Check migration record:**
+   ```bash
+   # In tenant database
+   SELECT * FROM custom_migrations WHERE name LIKE '%test_objects%';
+   ```
+
+4. **Create a record in the new object:**
+   ```bash
+   curl -X POST http://localhost:3000/api/test-objects \
+     -H "Authorization: Bearer <token>" \
+     -H "Content-Type: application/json" \
+     -d '{
+       "name": "My Test Record"
+     }'
+   ```
+
+## Troubleshooting
+
+### Migration Fails with SQL Error
+
+1. Check `custom_migrations` table for error details:
+   ```sql
+   SELECT id, name, error, status FROM custom_migrations 
+   WHERE status = 'failed';
+   ```
+
+2. Review the generated SQL in the `sql` column
+
+3. Common issues:
+   - Duplicate table names
+   - Invalid field names (reserved SQL keywords)
+   - Unsupported field types
+
+### Table Not Created
+
+1. Verify `custom_migrations` table exists:
+   ```sql
+   SHOW TABLES LIKE 'custom_migrations';
+   ```
+
+2. Check object service logs for migration execution errors
+
+3. Manually retry migration:
+   ```typescript
+   const migration = await tenantKnex('custom_migrations')
+     .where({ status: 'failed' })
+     .first();
+   await customMigrationService.executeMigration(tenantKnex, migration.id);
+   ```
+
+## Performance Considerations
+
+- **Table creation** is synchronous and happens immediately
+- **Migrations are cached** in custom_migrations table per tenant
+- **No file I/O** - all operations use database
+- **Index creation** optimized with proper indexes on common columns (tenantId, status, created_at)
+
+## Security
+
+- **Per-tenant isolation** - Each tenant's migrations stored separately
+- **No SQL injection** - Using Knex query builder for all operations
+- **Access control** - Migrations only created/executed by backend service
+- **Audit trail** - Complete history of all schema changes

+# Field Types & Views System
+
+A comprehensive field type system inspired by Laravel Nova, built with Vue 3 and shadcn-vue components. This system provides a flexible way to define and render fields in list, detail, and edit views.
+
+## Overview
+
+The system consists of:
+
+1. **Field Type Definitions** - TypeScript types and enums defining all available field types
+2. **Field Renderer** - A universal component that renders fields based on type and view mode
+3. **View Components** - ListView (data table), DetailView, and EditView components
+4. **Composables** - Utilities for working with fields and managing CRUD operations
+5. **Backend Support** - Extended field definitions with UI metadata
+
+## Field Types
+
+### Text Fields
+- `TEXT` - Single-line text input
+- `TEXTAREA` - Multi-line text input
+- `PASSWORD` - Password input (masked)
+- `EMAIL` - Email input with validation
+- `URL` - URL input
+
+### Numeric Fields
+- `NUMBER` - Numeric input
+- `CURRENCY` - Currency input with formatting
+
+### Selection Fields
+- `SELECT` - Dropdown select
+- `MULTI_SELECT` - Multi-select dropdown
+- `BOOLEAN` - Checkbox/switch
+
+### Date/Time Fields
+- `DATE` - Date picker
+- `DATETIME` - Date and time picker
+- `TIME` - Time picker
+
+### Relationship Fields
+- `BELONGS_TO` - Many-to-one relationship
+- `HAS_MANY` - One-to-many relationship
+- `MANY_TO_MANY` - Many-to-many relationship
+
+### Rich Content
+- `MARKDOWN` - Markdown editor
+- `CODE` - Code editor
+
+### File Fields
+- `FILE` - File upload
+- `IMAGE` - Image upload
+
+### Other
+- `COLOR` - Color picker
+- `JSON` - JSON editor
+
+## Usage
+
+### Basic Example
+
+```vue
+<script setup lang="ts">
+import { ListView, DetailView, EditView } from '@/components/views'
+import { FieldType, ViewMode } from '@/types/field-types'
+
+// Define your fields
+const fields = [
+  {
+    id: '1',
+    apiName: 'name',
+    label: 'Name',
+    type: FieldType.TEXT,
+    isRequired: true,
+    placeholder: 'Enter name',
+    showOnList: true,
+    showOnDetail: true,
+    showOnEdit: true,
+  },
+  {
+    id: '2',
+    apiName: 'email',
+    label: 'Email',
+    type: FieldType.EMAIL,
+    isRequired: true,
+    validationRules: [
+      { type: 'email', message: 'Invalid email format' }
+    ],
+  },
+  {
+    id: '3',
+    apiName: 'status',
+    label: 'Status',
+    type: FieldType.SELECT,
+    options: [
+      { label: 'Active', value: 'active' },
+      { label: 'Inactive', value: 'inactive' },
+    ],
+  },
+]
+
+// Create view config
+const listConfig = {
+  objectApiName: 'Contact',
+  mode: ViewMode.LIST,
+  fields,
+  searchable: true,
+  exportable: true,
+}
+
+const data = ref([])
+</script>
+
+<template>
+  <ListView 
+    :config="listConfig" 
+    :data="data"
+    selectable
+    @row-click="handleRowClick"
+    @create="handleCreate"
+  />
+</template>
+```
+
+### Using with Backend Data
+
+```vue
+<script setup lang="ts">
+import { useFields, useViewState } from '@/composables/useFieldViews'
+import { ListView } from '@/components/views'
+
+const { buildListViewConfig } = useFields()
+const { 
+  records, 
+  loading, 
+  fetchRecords,
+  showDetail,
+  showEdit,
+  deleteRecords 
+} = useViewState('/api/contacts')
+
+// Fetch object definition from backend
+const objectDef = await $fetch('/api/objects/contact')
+
+// Build view config from backend data
+const listConfig = buildListViewConfig(objectDef, {
+  searchable: true,
+  exportable: true,
+})
+
+// Fetch records
+await fetchRecords()
+</script>
+
+<template>
+  <ListView
+    :config="listConfig"
+    :data="records"
+    :loading="loading"
+    @row-click="showDetail"
+    @create="showEdit"
+    @delete="deleteRecords"
+  />
+</template>
+```
+
+### Sections and Grouping
+
+```typescript
+const detailConfig = {
+  objectApiName: 'Contact',
+  mode: ViewMode.DETAIL,
+  fields,
+  sections: [
+    {
+      title: 'Basic Information',
+      description: 'Primary contact details',
+      fields: ['firstName', 'lastName', 'email'],
+    },
+    {
+      title: 'Company Information',
+      fields: ['company', 'jobTitle', 'department'],
+    },
+    {
+      title: 'Additional Details',
+      fields: ['notes', 'tags'],
+      collapsible: true,
+      defaultCollapsed: true,
+    },
+  ],
+}
+```
+
+## Field Configuration
+
+### FieldConfig Interface
+
+```typescript
+interface FieldConfig {
+  // Basic properties
+  id: string
+  apiName: string
+  label: string
+  type: FieldType
+  
+  // Display
+  placeholder?: string
+  helpText?: string
+  defaultValue?: any
+  
+  // Validation
+  isRequired?: boolean
+  isReadOnly?: boolean
+  validationRules?: FieldValidationRule[]
+  
+  // View visibility
+  showOnList?: boolean
+  showOnDetail?: boolean
+  showOnEdit?: boolean
+  sortable?: boolean
+  
+  // Type-specific options
+  options?: FieldOption[]      // For select fields

+
+## Demo
+
+Visit `/demo/field-views` to see an interactive demo of all field types and views.
+
+## Best Practices
+
+1. **Field Organization** - Group related fields into sections for better UX
+2. **Validation** - Always provide clear validation messages
+3. **Help Text** - Use help text to guide users
+4. **Required Fields** - Mark required fields appropriately
+5. **Default Values** - Provide sensible defaults when possible
+6. **Read-Only Fields** - Use for system fields or computed values
+7. **Conditional Logic** - Use `dependsOn` for conditional field visibility
+8. **Mobile Responsive** - All components are mobile-responsive by default
+
+## Extending
+
+### Adding Custom Field Types
+
+1. Add new type to `FieldType` enum in [types/field-types.ts](../types/field-types.ts)
+2. Add rendering logic to [FieldRenderer.vue](../components/fields/FieldRenderer.vue)
+3. Update validation logic in [EditView.vue](../components/views/EditView.vue)
+
+### Custom Actions
+
+```typescript
+const config = {
+  // ... other config
+  actions: [
+    {
+      id: 'export-pdf',
+      label: 'Export PDF',
+      icon: 'FileDown',
+      variant: 'outline',
+      confirmation: 'Export this record to PDF?',
+      handler: async () => {
+        // Custom logic
+      }
+    }
+  ]
+}
+```

+- Validation is performed client-side before API calls
+- Use `v-memo` for large lists to optimize re-renders
+
+## Accessibility
+
+All components follow accessibility best practices:
+- Proper ARIA labels
+- Keyboard navigation support
+- Focus management
+- Screen reader friendly
+- High contrast support

+## 🚀 How to Use
+
+### 1. View the Demo
+```bash
+# Start the frontend dev server
+cd frontend
+npm run dev
+
+# Visit http://localhost:3000/demo/field-views
+```
+
+### 2. Use in Your App
+
+```vue
+<script setup>
+import { ListView } from '@/components/views'
+import { FieldType, ViewMode } from '@/types/field-types'
+
+const config = {
+  objectApiName: 'Contact',
+  mode: ViewMode.LIST,
+  fields: [
+    {
+      id: '1',
+      apiName: 'name',
+      label: 'Name',
+      type: FieldType.TEXT,
+      isRequired: true,
+    },
+    // ... more fields
+  ],
+}
+</script>
+
+<template>
+  <ListView :config="config" :data="records" />
+</template>
+```
+
+### 3. Integrate with Backend
+
+```typescript
+// Frontend
+const objectDef = await $fetch('/api/setup/objects/Contact/ui-config')
+const listConfig = buildListViewConfig(objectDef)
+
+// Backend - the endpoint returns properly formatted field configs
+GET /api/setup/objects/{objectApiName}/ui-config
+```
+
+## 🗃️ Database Changes
+
+Run the migration to add UI metadata support:
+
+```bash
+cd backend
+npm run migrate:tenant
+```
+
+This adds a `ui_metadata` JSONB column to the `field_definitions` table.
+
+## 📋 API Endpoints
+
+### New Endpoint
+- `GET /api/setup/objects/:objectApiName/ui-config` - Returns object definition with frontend-ready field configs
+
+### Existing Endpoints
+- `GET /api/setup/objects` - List all object definitions
+- `GET /api/setup/objects/:objectApiName` - Get object definition
+- `POST /api/setup/objects` - Create object definition
+- `POST /api/setup/objects/:objectApiName/fields` - Create field definition
+
+## ✨ Features
+
+### ListView
+- Sortable columns
+- Row selection with bulk actions
+- Search functionality
+- Custom actions
+- Export support
+- Responsive design
+
+### DetailView
+- Organized sections
+- Collapsible sections
+- Read-only optimized display
+- Custom actions
+- Field-type aware rendering
+
+### EditView
+- Client-side validation
+- Required field indicators
+- Help text and placeholders
+- Error messages
+- Organized sections
+- Collapsible sections
+
+### FieldRenderer
+- Handles all 20+ field types
+- Three rendering modes (list, detail, edit)
+- Type-specific components
+- Validation support
+- Formatting options
+
+## 🔄 Integration with Existing System
+
+The field type system integrates seamlessly with your existing multi-tenant app builder:
+
+1. **Object Definitions** - Uses existing `object_definitions` table
+2. **Field Definitions** - Extends existing `field_definitions` table with `ui_metadata`
+3. **Runtime Pages** - Dynamic route at `/app/objects/:objectName` automatically renders appropriate views
+4. **Composables** - `useFieldViews` provides utilities for mapping backend data
+
+## 📝 Next Steps
+
+1. **Run the migration** to add UI metadata support
+2. **Test the demo** at `/demo/field-views`
+3. **Integrate with your objects** using the dynamic route
+4. **Customize field types** as needed for your use case
+5. **Add validation rules** to field definitions
+6. **Configure UI metadata** for better UX
+
+## 🎯 Best Practices
+
+1. Always provide clear labels and help text
+2. Use validation rules with custom messages
+3. Organize fields into logical sections
+4. Mark required fields appropriately
+5. Use appropriate field types for data
+6. Test on mobile devices
+7. Use read-only for system fields
+
+## 📚 Documentation

+
+## 🐛 Troubleshooting
+
+### Missing UI Metadata
+If fields don't render correctly, ensure:
+1. Migration has been run
+2. `uiMetadata` is populated in database
+3. Field types are correctly mapped
+
+### Components Not Found
+Ensure all shadcn-vue components are installed:
+```bash
+cd frontend
+npx shadcn-vue@latest add table checkbox switch textarea calendar popover command badge
+```
+
+### Type Errors
+Ensure TypeScript types are properly imported:
+```typescript
+import { FieldType, ViewMode, type FieldConfig } from '@/types/field-types'
+```
+
+## 💡 Tips
+
+1. Use the `FieldMapperService` to automatically generate UI configs
+2. Leverage `useViewState` composable for CRUD operations
+3. Customize field rendering by extending `FieldRenderer.vue`
+4. Add custom actions to views for workflow automation
+5. Use sections to organize complex forms
+

+# Multi-Tenant Migration - Implementation Summary
+
+## Overview
+
+The platform has been migrated from a single-database multi-tenant architecture to a **one database per tenant** architecture with subdomain-based tenant identification.
+
+## Architecture Changes
+
+### Database Layer
+
+- **Central Database** (Prisma): Stores tenant metadata, domain mappings, encrypted credentials
+- **Tenant Databases** (Knex.js + Objection.js): One MySQL database per tenant with isolated data
+
+### Tenant Identification
+
+- **Before**: `x-tenant-id` header
+- **After**: Subdomain extraction from hostname (e.g., `acme.routebox.co` → tenant `acme`)
+- **Fallback**: `x-tenant-id` header for local development
+
+### Technology Stack
+
+- **Central DB ORM**: Prisma 5.8.0
+- **Tenant DB Migration**: Knex.js 3.x
+- **Tenant DB ORM**: Objection.js 3.x
+- **Database Driver**: mysql2
+

+### Central Database Schema (Prisma)
+
+```
+prisma/
+├── schema-central.prisma         # Tenant, Domain models
+└── migrations/                   # Will be created when generating
+```
+
+## Setup Instructions
+
+### 1. Environment Configuration
+
+Copy `.env.example` to `.env` and configure:
+
+```bash
+cd /root/neo/backend
+cp .env.example .env
+```
+
+Generate encryption key:
+
+```bash
+node -e "console.log(require('crypto').randomBytes(32).toString('hex'))"
+```
+
+Update `.env` with the generated key and database URLs:
+
+```env
+CENTRAL_DATABASE_URL="mysql://user:password@platform-db:3306/central_platform"
+ENCRYPTION_KEY="<generated-32-byte-hex-key>"
+DB_ROOT_USER="root"
+DB_ROOT_PASSWORD="root"
+```
+
+### 2. Central Database Setup
+
+Generate Prisma client and run migrations:
+
+```bash
+cd /root/neo/backend
+npx prisma generate --schema=./prisma/schema-central.prisma
+npx prisma migrate dev --schema=./prisma/schema-central.prisma --name init
+```
+
+### 3. Tenant Provisioning
+
+Create a new tenant via API:
+
+```bash
+curl -X POST http://localhost:3000/setup/tenants \
+  -H "Content-Type: application/json" \
+  -d '{
+    "name": "Acme Corporation",
+    "slug": "acme",
+    "primaryDomain": "acme"
+  }'
+```
+
+This will:
+
+1. Create MySQL database `tenant_acme`
+2. Create database user `tenant_acme_user`
+3. Run all Knex migrations on the new database
+4. Seed default roles and permissions
+5. Store encrypted credentials in central database
+6. Create domain mapping (`acme` → tenant)
+
+### 4. Testing Subdomain Routing
+
+Update your hosts file or DNS to point subdomains to your server:
+
+```
+127.0.0.1  acme.localhost
+127.0.0.1  demo.localhost
+```
+
+Access the application:
+
+- Central setup: `http://localhost:3000/setup/tenants`
+- Tenant app: `http://acme.localhost:3000/`
+- Different tenant: `http://demo.localhost:3000/`
+
+## Migration Status
+
+### ✅ Completed
+
+- [x] Central database schema (Tenant, Domain models)
+- [x] Knex + Objection.js installation
+- [x] TenantDatabaseService with dynamic connections
+- [x] Password encryption/decryption (AES-256-CBC)

+- [x] Knex migrations for base tenant schema
+- [x] Tenant middleware with subdomain extraction
+- [x] Tenant provisioning service (create/destroy)
+- [x] Schema management service (dynamic table creation)
+
+### 🔄 Pending
+
+- [ ] Generate Prisma client for central database
+- [ ] Run Prisma migrations for central database
+- [ ] Migrate AuthService from Prisma to Objection.js
+- [ ] Migrate RBACService from Prisma to Objection.js
+- [ ] Migrate ObjectService from Prisma to Objection.js
+- [ ] Migrate AppBuilderService from Prisma to Objection.js
+- [ ] Update frontend to work with subdomains
+- [ ] Test tenant provisioning flow
+- [ ] Test subdomain routing
+- [ ] Test database isolation
+
+## Service Migration Guide
+
+### Example: Migrating a Service from Prisma to Objection
+
+**Before (Prisma):**
+
+```typescript
+async findUser(email: string) {
+  return this.prisma.user.findUnique({ where: { email } });
+}
+```
+
+**After (Objection + Knex):**
+
+```typescript
+constructor(private readonly tenantDbService: TenantDatabaseService) {}
+
+async findUser(tenantId: string, email: string) {
+  const knex = await this.tenantDbService.getTenantKnex(tenantId);
+  return User.query(knex).findOne({ email });
+}
+```
+
+### Key Changes
+
+1. Inject `TenantDatabaseService` instead of `PrismaService`
+2. Get tenant Knex connection: `await this.tenantDbService.getTenantKnex(tenantId)`
+3. Use Objection models: `User.query(knex).findOne({ email })`
+4. Pass `tenantId` to all service methods (extract from request in controller)
+
+## API Changes
+
+### Tenant Provisioning Endpoints
+
+**Create Tenant**
+
+```
+POST /setup/tenants
+Content-Type: application/json
+
+{
+  "name": "Company Name",
+  "slug": "company-slug",
+  "primaryDomain": "company",
+  "dbHost": "platform-db",  // optional
+  "dbPort": 3306            // optional
+}
+
+Response:
+{
+  "tenantId": "uuid",
+  "dbName": "tenant_company-slug",
+  "dbUsername": "tenant_company-slug_user",
+  "dbPassword": "generated-password"
+}
+```
+
+**Delete Tenant**
+
+```
+DELETE /setup/tenants/:tenantId
+
+Response:
+{
+  "success": true
+}
+```
+
+## Security Considerations
+
+1. **Encryption**: Tenant database passwords are encrypted with AES-256-CBC before storage
+2. **Isolation**: Each tenant has a dedicated MySQL database and user
+3. **Credentials**: Database credentials stored in central DB, never exposed to tenants
+4. **Subdomain Validation**: Middleware validates tenant exists and is active before processing requests
+
+## Troubleshooting
+
+### Connection Issues
+
+Check tenant connection cache:
+
+```typescript
+await this.tenantDbService.disconnectTenant(tenantId);
+const knex = await this.tenantDbService.getTenantKnex(tenantId); // Fresh connection
+```
+
+### Migration Issues
+
+Run migrations manually:
+
+```bash
+cd /root/neo/backend
+npx knex migrate:latest --knexfile=knexfile.js
+```
+
+### Encryption Key Issues
+
+If `ENCRYPTION_KEY` is not set, generate one:
+
+```bash
+node -e "console.log(require('crypto').randomBytes(32).toString('hex'))"
+```
+
+## Next Steps
+
+1. **Generate Central DB Schema**
+
+   ```bash
+   npx prisma generate --schema=./prisma/schema-central.prisma
+   npx prisma migrate dev --schema=./prisma/schema-central.prisma
+   ```
+
+2. **Migrate Existing Services**
+
+   - Start with `AuthService` (most critical)
+   - Then `RBACService`, `ObjectService`, `AppBuilderService`
+   - Update all controllers to extract `tenantId` from request
+
+3. **Frontend Updates**
+
+   - Update API calls to include subdomain
+   - Test cross-tenant isolation
+   - Update login flow to redirect to tenant subdomain
+
+4. **Testing**
+
+   - Create multiple test tenants
+   - Verify data isolation
+   - Test subdomain routing
+   - Performance testing with multiple connections
+
+5. **Production Deployment**
+   - Set up wildcard DNS for subdomains
+   - Configure SSL certificates for subdomains
+   - Set up database backup strategy per tenant
+   - Monitor connection pool usage

+This guide walks you through migrating existing services from the single-database architecture to the new multi-database per-tenant architecture.
+
+## Architecture Comparison
+
+### Before (Single Database)
+
+```typescript
+// Single Prisma client, data segregated by tenantId column
+@Injectable()
+export class UserService {
+  constructor(private prisma: PrismaService) {}
+
+  async findUserByEmail(tenantId: string, email: string) {
+    return this.prisma.user.findFirst({
+      where: { tenantId, email },
+    });
+  }
+}
+```
+
+### After (Multi-Database)
+
+```typescript
+// Dynamic Knex connection per tenant, complete database isolation
+@Injectable()
+export class UserService {
+  constructor(private tenantDb: TenantDatabaseService) {}
+
+  async findUserByEmail(tenantId: string, email: string) {
+    const knex = await this.tenantDb.getTenantKnex(tenantId);
+    return User.query(knex).findOne({ email });
+  }
+}
+```

+## Quick Reference
+
+### Query Patterns
+
+**Simple Query**
+
+```typescript
+// Prisma
+const user = await this.prisma.user.findUnique({ where: { tenantId, id } });
+
+// Objection
+const knex = await this.tenantDb.getTenantKnex(tenantId);
+const user = await User.query(knex).findById(id);
+```
+
+**Query with Relations**
+
+```typescript
+// Prisma
+const user = await this.prisma.user.findUnique({
+  where: { tenantId, id },
+  include: { roles: { include: { permissions: true } } },
+});
+
+// Objection
+const user = await User.query(knex)
+  .findById(id)
+  .withGraphFetched("roles.permissions");
+```
+
+**Create**
+
+```typescript
+// Prisma
+const user = await this.prisma.user.create({ data: { ... } });
+
+// Objection
+const user = await User.query(knex).insert({ ... });
+```
+
+**Update**
+
+```typescript
+// Prisma
+const user = await this.prisma.user.update({ where: { id }, data: { ... } });
+
+// Objection
+const user = await User.query(knex).patchAndFetchById(id, { ... });
+```
+
+**Delete**
+
+```typescript
+// Prisma
+await this.prisma.user.delete({ where: { id } });
+
+// Objection
+await User.query(knex).deleteById(id);
+```
