SQLAlchemyModelFactory is not a generic class

[bartektrybala]

When you define a factory like this:

class UserFactory(factory.alchemy.SQLAlchemyModelFactory):
    class Meta:
        model = UserModel

    email = factory.Faker("email")

mypy throws error:
Missing type parameters for generic type "SQLAlchemyModelFactory" [type-arg]

but when add the parameter like this: factory.alchemy.SQLAlchemyModelFactory[UserModel] then when you execute the code it throws an error: E TypeError: <SQLAlchemyModelFactory (abstract)> is not a generic class

It's because stubs define SQLAlchemyModelFactory as a generic class but in fact it's not generic. In the source code of factory-boy you've got

class SQLAlchemyModelFactory(base.Factory)

and

class Factory(BaseFactory[T], metaclass=FactoryMetaClass)

but SQLAlchemyModelFactory itself is not generic. Could you fix that? For now I have to ignore the line for mypy
