# FastAPI & Pydantic v2 Standards
|
|
|
|
## Pydantic v2 Rules
|
|
- NEVER use `.dict()` or `.json()`. ALWAYS use `.model_dump()` and `.model_dump_json()`.
|
|
- NEVER use `@validator` or `@root_validator`. ALWAYS use `@field_validator` and `@model_validator(mode="before|after")`.
|
|
- NEVER use `schema_extra`. Use `json_schema_extra` inside the `model_config` dict.
|
|
- Use `pydantic_settings.BaseSettings` for all environment variable configurations.
|
|
|
|
## FastAPI Rules
|
|
- ALWAYS use `typing.Annotated` for dependency injection (e.g., `db: Annotated[AsyncSession, Depends(get_db)]`).
|
|
- Do not use `def` for endpoints that perform I/O; always use `async def`.
|
|
- Raise `fastapi.HTTPException` for expected client errors instead of returning standard dictionaries.
