### Pydantic v1 parameters { #pydantic-v1-parameters }

If you need to use some of the FastAPI-specific tools for parameters like `Body`, `Query`, `Form`, etc. with Pydantic v1 models, you can import them from `fastapi.temp_pydantic_v1_params` while you finish the migration to Pydantic v2:

        // artifacts available.
        ArtifactRepositoryPolicy policy = metadata.getPolicy(repository);
