permissions

Create new a permissions table linking a user with an object

The table created will be called ‘<name>_permission’, with <name> being the name of the table where this mixin is used

query: t.ClassVar[Query]

A SQLAlchemy query for a model. Equivalent to db.session.query(Model). Can be customized per-model by overriding query_class.

Warning

The query interface is considered legacy in SQLAlchemy. Prefer using session.execute(select()) instead.
