Can I make list_filter in django admin to only show referenced ForeignKeys?

Question

I have a django application which has two models like this:

class MyModel(models.Model):
    name = models.CharField()
    country = models.ForeignKey(\'Coun         


        

Answer 1

I’d change lookups in darklow's code like this:

def lookups(self, request, model_admin):
    users = User.objects.filter(id__in = model_admin.model.objects.all().values_list('user_id', flat = True).distinct())
    return [(user.id, unicode(user)) for user in users]

This is much better for database ;)
