[Patch] Identity-related models with non-default names won't work with the SQLAlchemy auth backend

[Gustavo]

Try renaming, in your data model, 'User' by 'Member', or 'Group' by 'Team', or both. Then update your app_cfg.py file accordingly. Finally, run `paster setup-app development.ini' - you'll get an error like this:

AttributeError: 'module' object has no attribute 'User'

That's because of setup_sa_auth_backend() in tg.config. It assumes that self.model.User, self.model.Group and self.model.Permission exist, but they may exist under a different name.

With the proposed patch, our app_cfg.py files *must* define the following attributes in base_config.sa_auth: "user_class", "group_class" and "permission_class", so that we don't rely on "default" classes that may not exist.

[Gustavo]

A patch to the default template, so that it includes the now mandatory configuration parameters. It also fixes a typo: base_config.sa_auth.user should be base_config.sa_auth.user_class

It also fixes a typo: base_config.sa_auth.user should be base_config.sa_auth.user_class

I think TG2 is using two different attributes for the same thing. If "base_config.sa_auth.user" is not defined, when you try to start the application you'll get an error like this:

I think the references to "user" should be replaced by "user_class".

Replying to Gustavo:

It also fixes a typo: base_config.sa_auth.user should be base_config.sa_auth.user_class

I think TG2 is using two different attributes for the same thing. If "base_config.sa_auth.user" is not defined, when you try to start the application you'll get an error like this:
