sqlalchemy-stubs

Infers precise types for model attributes and columns, catching mismatches like assigning an int to a string column, as shown in the README example with User(id=42, name=42).

The mypy plugin understands SQLAlchemy's dynamic patterns, such as string-based relationship references, enabling seamless type checking without modifying SQLAlchemy code.

Allows static type checking to catch type errors during development, improving code reliability and reducing runtime bugs in SQLAlchemy-based applications.

Supports simple relationships with forward references via TYPE_CHECKING imports or string literals, making common ORM patterns type-safe without manual workarounds.
