Override UserManager

[thibaultj]

In contrib.auth, the User class is affected a custom UserManager manager. I cannot find any clean way to override this manager, or to define a new one.

This is a problem in the following case: I created a middleware to manage acl. So in every request, I need to access request.user.profile.something. I'd like to override the get_query_set() method of the UserManager, to use select_related().

The only possible solution seems to monkey patch user class in a middleware, as suggested here :

Use ​https://docs.djangoproject.com/en/dev/ref/signals/#class-prepared to attach to the User class registration and then use manager.contribute_to_class to attach your manager. Even if it doesn't work, I don't think anything should be changed now since app-refactor will provide that afaik.

This is more a usage question than a bug in Django, and apollo13 provided a solution.
