## 🎓 Learning Resources
|
|
|
|
### Understanding the Pattern
|
|
|
|
**Best examples to study:**
|
|
1. `services/orders/app/services/tenant_deletion_service.py` - Complete, well-commented
|
|
2. `services/recipes/app/services/tenant_deletion_service.py` - Shows CASCADE pattern
|
|
3. `services/suppliers/app/services/tenant_deletion_service.py` - Complex dependencies
|
|
|
|
### Key Concepts
|
|
|
|
**Base Class Pattern:**
|
|
```python
|
|
class YourServiceDeletionService(BaseTenantDataDeletionService):
|
|
async def get_tenant_data_preview(tenant_id):
|
|
# Return counts of what would be deleted
|
|
|
|
async def delete_tenant_data(tenant_id):
|
|
# Actually delete the data
|
|
# Return TenantDataDeletionResult
|
|
```
|
|
|
|
**Deletion Order:**
|
|
```python
|
|
# Always: Children first, then parents
|
|
delete(OrderItem) # Child
|
|
delete(OrderStatus) # Child
|
|
delete(Order) # Parent
|
|
```
|
|
|
|
**Error Handling:**
|
|
```python
|
|
try:
|
|
deleted = await db.execute(delete(Model)...)
|
|
result.add_deleted_items("models", deleted.rowcount)
|
|
except Exception as e:
|
|
result.add_error(f"Model deletion: {str(e)}")
|
|
```
