On this particular point, from the perspective of the reusable
applications themselves, you don't need to worry about merging profile
models, even if you are potentially working with many of them in your
overall project. Going with the forum example, if your forum
application defines its own profile Model which addresses all of its
specific needs, it doesn't benefit it in any way if it has access to
some kind of merged profile instead - it does, however, introduce the
potential for conflicts.
Personally, I never rely on the AUTH_PROFILE_MODEL setting and the
User.get_profile method in reusable applications, I only use those in
my main project. It's not a lot of work to add a method to your
application's profile Manager to load and cache a user's
application-specific profile in a manner similar to User.get_profile.
Since I'm actually working on a reusable forum application at the
moment, here's an example of what I mean:
class ForumProfileManager(models.Manager):
def get_for_user(self, user):
"""
Returns the ForumProfile for the given user, creating it first if
necessary and caching it the first time it is looked up.
"""
if not hasattr(user, '_forum_profile_cache'):
profile, created = self.get_or_create(user=user)
user._forum_profile_cache = profile
return user._forum_profile_cache
