[Fixed]-Reorder users in django auth

There is a way using ModelAdmin objects to specify your own form. By specifying your own form, you have complete control over the form’s composition and validation.

Say that the model which has an FK to User is Foo.

Your myapp/models.py might look like this:

from django.db import models
from django.contrib.auth.models import User

class Foo(models.Model):
    user = models.ForeignKey(User)
    some_val = models.IntegerField()

You would then create a myapp/admin.py file containing something like this:

from django.contrib.auth.models import User
from django import forms
from django.contrib import admin

class FooAdminForm(forms.ModelForm):
    user = forms.ModelChoiceField(queryset=User.objects.order_by('username'))

    class Meta:
        model = Foo

 class FooAdmin(admin.ModelAdmin):
     form = FooAdminForm

 admin.site.register(Foo, FooAdmin)

Once you’ve done this, the <select> dropdown will order the user objects according to username. No need to worry about to other fields on Foo… you only need to specify the overrides in your FooAdminForm class. Unfortunately, you’ll need to provide this custom form definition for every model having an FK to User that you wish to present in the admin site.

Jarret’s answer above should actually read: 

from django.contrib.auth.models import User
from django.contrib import admin
from django import forms
from yourapp.models import Foo

class FooAdminForm(forms.ModelForm):
    class Meta:
        model = Foo

    def __init__(self, *args, **kwds):
        super(FooAdminForm, self).__init__(*args, **kwds)
        self.fields['user'].queryset = User.objects.order_by(...)

class FooAdmin(admin.ModelAdmin):
    # other stuff here
    form = FooAdminForm

admin.site.register(Foo, FooAdmin)

so the queryset gets re-evaluated each time you create the form, as opposed to once, when the module containing the form is imported.
