# Field Rename Implementation Complete

## Summary
Complete removal of old field names (`site_entity_type`, `cluster_role`, `entity_type`, `html_content`) with NO backward compatibility. All references updated to use new field names (`content_type`, `content_structure`, `content_html`) across entire codebase.

## Database Migration

### SQL Migration File
✅ `/backend/rename_fields_migration.sql`
- Renames 5 tables' columns
- Conditional checks (only rename if old column exists)
- Index renames
- Tables affected:
  1. `igny8_content_ideas` (2 columns)
  2. `igny8_tasks` (2 columns)
  3. `igny8_content` (3 columns)
  4. `igny8_content_taxonomy_map` (1 column)
  5. `igny8_taxonomy_terms` (1 column)

### How to Execute
```bash
# Option 1: Via psql (if available)
psql -U username -d database_name -f /data/app/igny8/backend/rename_fields_migration.sql

# Option 2: Via Django shell
cd /data/app/igny8/backend
source .venv/bin/activate
python manage.py dbshell < rename_fields_migration.sql

# Option 3: Via Django migration (recommended)
python manage.py makemigrations
python manage.py migrate
```

## Testing & Validation

### Backend Testing Script
✅ `/backend/test_field_rename.py`
- Tests model field access
- Verifies database column names
- Validates CHOICES definitions
- Checks for old column names

### Run Test
```bash
cd /data/app/igny8/backend
source .venv/bin/activate
python manage.py shell < test_field_rename.py
```

### Manual API Testing
Test these endpoints after migration:

1. **Ideas API:**
   - GET `/api/planner/ideas/` - List ideas
   - POST `/api/planner/ideas/` - Create idea with new fields
   - POST `/api/planner/ideas/{id}/bulk_queue_to_writer/` - Queue to writer

2. **Tasks API:**
   - GET `/api/writer/tasks/` - List tasks
   - GET `/api/writer/tasks/?content_type=post` - Filter by type
   - GET `/api/writer/tasks/?content_structure=article` - Filter by structure

3. **Content API:**
   - GET `/api/writer/content/` - List content
   - GET `/api/writer/content/?content_type=page` - Filter by type

### Frontend Testing
1. Navigate to Ideas page - verify:
   - Filters show all 14 structures
   - Create form has all types/structures
   - Table displays correctly
   - Bulk queue works

2. Navigate to Tasks page - verify:
   - Filters work with new values
   - Table columns show type/structure badges
   - No console errors

3. Navigate to Content page - verify:
   - Filters work
   - Table displays correctly
   - PostEditor shows content_structure

## Breaking Changes
⚠️ **NO BACKWARD COMPATIBILITY** - This is a breaking change:
- Old API field names (`site_entity_type`, `cluster_role`) no longer work
- Old database columns will be renamed (data preserved)
- Any external integrations must update to new field names

## Rollback Plan
If issues occur:
1. Reverse SQL migration (see `rename_fields_migration.sql` comments)
2. Revert all code changes via git
3. Original columns: `site_entity_type`, `cluster_role`, `entity_type`, `html_content`

## Files Modified
**Backend (7 files):**
- Models: 2 files
- Views: 1 file
- Serializers: 1 file (already correct)
- Services: 2 files
- AI: 2 files

**Frontend (8 files):**
- Interfaces: 1 file
- Pages: 3 files
- Configs: 4 files (1 new)

**Database:**
- SQL migration: 1 file (not yet executed)
- Test script: 1 file

**Total: 17 files modified/created**

## Next Steps
