For the django admin, how do I add a field to the User model and have it editable in the admin?

Question

I'm trying to understand the django admin better and at the same time, I'm trying to add one more field to the current user admin. In models.py I've done ``` User.add_to_class('new_field', models.BooleanField(default=False)) ``` and in admin.py I've got the following (with fieldsets basically just copied from django/contrib/auth/admin.py) ``` class AdjUserAdmin(UserAdmin): list_display = UserAdmin.list_display + ('new_field',) list_filter = UserAdmin.list_filter + ('new_field',) fieldsets = UserAdmin.fieldsets fieldsets[1][1]['fields'] = ('first_name','last_name','email','new_field') ``` The problem is, when I do this I get the error: `AdjUserAdmin.fieldsets[4][1]['fields']' refers to field 'new_field' that is missing from the form.` I've looked at UserChangeForm, but it looks like it's already correctly pulling in User as the model.

First the "is it plugged in?" question -- Have you manually added new_field to the users table in the database? Syncdb wouldn't have taken care of that, of course.

After that, I would try appending the fields onto the existing UserAdmin rather than rebuilding it from scratch:

```
from django.contrib.auth.admin import UserAdmin

UserAdmin.list_display += ('new_field',)  # don't forget the commas
UserAdmin.list_filter += ('new_field',)
UserAdmin.fieldsets += ('new_field',)
```
