"docstring": "# CRUD Template\n\n## Summary\n\nEvery resource follows the same four-file slice. Repetition is intentional: it\nmakes the codebase predictable and generatable.\n\n---\n\n## The slice\n\n```\ndomain/<resource>/\n models.py # pure Pydantic model (no DB fields)\n ports/\n db.py # document model + repository factory\n service.py # service class + factory\n converters.py # (optional) transforms\n```\n\n## models.py\n\nA framework-free Pydantic model describing the business shape.\n\n```python\nclass Item(BaseModel):\n name: str\n quantity: int = 0\n```\n\n## ports/db.py\n\nThe persistence model extends the business model and adds database concerns.\nThe repository factory selects the right repository flavour.\n\n```python\nclass ItemDocument(Item, BaseDocument): # BaseDocument adds id/created_at/...\n pass\n\ndef create_item_repo(*, owner_repo=None) -> ItemRepository:\n return repo_factory(\n collection=\"items\",\n document=ItemDocument,\n populate_rules=[PopulateRule(field=\"owner\", collection=\"users\")],\n cache=None, # or a CachedBaseRepository config\n )\n```\n\n## ports/service.py\n\nThe service is built through the DI library, injecting the repository. The\ngeneric CRUD base provides `create/read/update/patch/delete/search/...`.\n\n```python\nclass ItemService(CrudsServiceAdaptor[Item, ItemDocument]):\n model = Item\n schema = ItemDocument\n\ndef get_item_service(repo) -> ItemService:\n return build(ItemService, instances={\"repo\": repo})\n```\n\n## Naming conventions\n\n| Concept | Convention |\n|---|---|\n| collection | plural snake case (`items`) |\n| document | `<Resource>Document` |\n| repository factory | `create_<resource>_repo` |\n| service | `<Resource>Service` |\n| service factory | `get_<resource>_service` |\n| resource key | `<resource>_svc` |\n| operationId | `list_items`, `create_item`, ... |\n\n## Optional files\n\n- `converters.py` — pure functions mapping between domain types.\n- `ports/enrichment.py` — adapts a pipeline into an async callable the service\n can invoke (used when a resource is populated by a pipeline).\n",
