# Object and Record Creation Test

## Goal
Test that the Objection.js model system properly handles system-managed fields:
- ownerId (should be auto-set from userId)
- created_at (should be auto-set to current timestamp)
- updated_at (should be auto-set to current timestamp)
- id (should be auto-generated UUID)

Users should NOT need to provide these fields when creating records.

## Test Sequence

### 1. Create an Object (if not exists)

```bash
curl -X POST http://localhost:3001/api/objects \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_JWT_TOKEN" \
  -H "X-Tenant-ID: tenant1" \
  -d '{
    "apiName": "TestContact",
    "label": "Test Contact",
    "pluralLabel": "Test Contacts",
    "description": "Test object for model validation"
  }'
```

Expected response:
```json
{
  "id": "uuid...",
  "apiName": "TestContact",
  "label": "Test Contact",
  "tableName": "test_contacts",
  "...": "..."
}
```

### 2. Create a Record WITHOUT System Fields

This should succeed and system fields should be auto-populated:

```bash
curl -X POST http://localhost:3001/api/records/TestContact \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_JWT_TOKEN" \
  -H "X-Tenant-ID: tenant1" \
  -d '{
    "name": "John Doe",
    "email": "john@example.com"
  }'
```

Expected response:
```json
{
  "id": "uuid-auto-generated",
  "name": "John Doe",
  "email": "john@example.com",
  "ownerId": "current-user-id",
  "created_at": "2025-01-26T...",
  "updated_at": "2025-01-26T...",
  "tenantId": "tenant-uuid"
}
```

### 3. Verify Fields Were Set Automatically

```bash
curl -X GET http://localhost:3001/api/records/TestContact/RECORD_ID \
  -H "Authorization: Bearer YOUR_JWT_TOKEN" \
  -H "X-Tenant-ID: tenant1"
```

Verify response includes:
- ✅ id (UUID)
- ✅ ownerId (matches current user ID)
- ✅ created_at (timestamp)
- ✅ updated_at (timestamp)
- ✅ name, email (provided fields)

### 4. Update Record and Verify updated_at Changes

Get the created_at value, wait a second, then update:

```bash
curl -X PATCH http://localhost:3001/api/records/TestContact/RECORD_ID \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_JWT_TOKEN" \
  -H "X-Tenant-ID: tenant1" \
  -d '{
    "name": "Jane Doe"
  }'
```

Verify in response:
- ✅ name is updated to "Jane Doe"
- ✅ updated_at is newer than original created_at
- ✅ created_at is unchanged
- ✅ ownerId is unchanged (not overwritable)

## Key Points to Verify

1. **System Fields Not Required**: Record creation succeeds without ownerId, created_at, updated_at
2. **Auto-Population**: System fields are populated automatically by model hooks
3. **Immutable Owner**: ownerId cannot be changed via update (filtered out in ObjectService.updateRecord)
4. **Timestamp Management**: created_at stays same, updated_at changes on update
5. **Model Used**: Debug logs should show model is being used (look for "Registered model" logs)

## Troubleshooting

If tests fail, check:

1. **Model Registration**: Verify model appears in logs after object creation
2. **Hook Execution**: Add debug logs to DynamicModel.$beforeInsert and $beforeUpdate
3. **Model Binding**: Verify getBoundModel returns properly bound model with correct knex instance
4. **Field Validation**: Check if JSON schema validation is preventing record creation
