#25281 assigned Cleanup/optimization

Permission strings don't uniquely identify permissions

Description

APIs related to permissions (e.g. User.has_perm()) take a 'permission string' argument of format "<app label>.<permission codename>" to refer to Permissions.

But each permission is uniquely defined on the model level as a tuple of (content type, permission name). As content type refers to concrete model within a concrete app, we should be using permission string of the format "<app label>.<model name>.<permission codename>".

This becomes a concrete issue once one wants to define custom permissions for their models, and doesn't observe the convention of putting the model name in the permission codenames (or wants to inherit the custom permissions form an abstract model).
