Django Admin: Ordering of ForeignKey and ManyToManyField relations referencing User
This
class Meta: ordering = ['username']should be
ordering = ['user__username']if it's in your UserProfile admin class. That'll stop the exception, but I don't think it helps you.
Ordering the User model as you describe is quite tricky, but see http://code.djangoproject.com/ticket/6089#comment:8 for a solution.
One way would be to define a custom form to use for your Team model in the admin, and override the manager field to use a queryset with the correct ordering:
from django import formsclass TeamForm(forms.ModelForm): manager = forms.ModelChoiceField(queryset=User.objects.order_by('username')) class Meta: model = Teamclass TeamAdmin(admin.ModelAdmin): list_display = ('name', 'manager') form = TeamForm
This might be dangerous for some reason, but this can be done in one line in your project's models.py file:
User._meta.ordering=["username"]
