exdrf-gen-al2r

exdrf-gen-al2r is an exdrf-gen plugin that emits FastAPI APIRouter stubs from SQLAlchemy-backed ExDataset metadata. List and read handlers are typed with XxxEx; create uses XxxCreate. Patch is emitted only when exdrf-gen-al2pd would emit XxxEdit (composite PK–only link tables skip PATCH). The SCHEMAS-PKG argument must point at the package tree produced by al2pd.

Python 3.12.2+ is required.

Command-line usage

exdrf-gen al2r DATASET OUT-PATH DB-MODULE SCHEMAS-PKG

Or: python -m exdrf_gen al2r ....

• DATASET — module.path:DeclarativeBase.
• OUT-PATH — directory for *_routes.py and __init__.py (or EXDRF_AL2R_PATH).
• DB-MODULE — dotted import path for ORM classes (from DB-MODULE import Model).
• SCHEMAS-PKG — dotted root package where al2pd wrote schemas (or EXDRF_AL2R_SCHEMAS). Import path per resource is SCHEMAS-PKG.<categories...>.<snake_case_name_plural> (e.g. myapp.schemas.widgets for Widget at the root category).

Path parameters for GET/PATCH follow resource.primary_fields() order (e.g. {left_id}/{right_id} for composite keys).

Dependencies

exdrf-gen, exdrf-al, click, exdrf-gen-al2pd (for resource_generates_edit_payload). Generated routers import FastAPI and SQLAlchemy — add those to the application environment.
