Django Model Manager related filter

Question

I'd like to filter the related entries in the manager:

class UserTravelsCarsManager(models.Manager): def for_user(self, user): return super(UserTravelsCarsManager, self).get_query_set().filter(user=user) class TravelsCars(models.Model): user = models.ForeignKey(User) name = models.CharField(max_length=255) ... objects = UserTravelsCarsManager() class UserTravelsManager(models.Manager): def for_user(self, user): return super(UserTravelsManager, self).get_query_set().filter(user=user) class Travels(models.Model, ClonableMixin): user = models.ForeignKey(User) vehicle = models.ForeignKey(TravelsCars) ... objects = UserTravelsManager()

It won't work by itself. I get all of the cars for all users. I've tried:

return super(UserTravelsManager, self).get_query_set().filter(user=user, vehicle__user=user)

Which also doesn't work.

UPDATE: Just to be clear the entries for Travels are filtered. Just the related TravelsCars aren't filtered if I query them through Travels.

What am I doing wrong?

Instead of super(UserTravelsCarsManager, self).get_query_set().filter... try to use self.filter(user=user). Same in UserTravelsManager

What is the same result as before? What happens? What do you see? What error do you get?

I mean I get the same entries as before..that means unfiltered...entries for all users instead of entries just for the current (logged in) user...
