Django-admin won't allow me to modify user permissions and groups - django

Question

When editing user model through admin interface, here's what I see:
And here's what I expect to see:
The second one allows me to modify the user permissions, the first one does not.
The User model I use on the first screenshot inherits from AbstractUser and is registered in the following way:
from django.contrib import admin
import accounts.models
admin.site.register(accounts.models.User)
In my settings:
DEBUG = True
AUTH_USER_MODEL = 'accounts.User'
What can be the problem? How do I get from the first screenshot to the second?

Answer 1

Had the same issue but the solution is quite simple. In your admin.py file just add 'groups', 'user_permissions' to filter_horizontal = ()
i.e
filter_horizontal = ('groups', 'user_permissions')
that is basically it.

Answer 2

OK, the actual problem was that I inherited not from AbstractUser but from AbstractBaseUser and forgot about PermissionsMixin (the mixin adds the apropriate fields). So I should've done something like this.

Answer 3

The problem in my case is that, I was inheriting only from admin.UserAdmin, I had to create a UserAdmin class that inherits from admin.ModelAdmin and add the filter_horizontal to it, I'm adding the filter every time I modify the UserAdmin, it should look like:
class UserAdmin(UserAdmin):
model = User
filter_horizontal = ('groups', 'user_permissions')
add_form = UserCreationForm
form = UserChangeForm
list_display = ('email', 'is_staff', 'is_active',)
list_filter = ('email', 'is_staff', 'is_active',)
fieldsets = (
# ('Zone label',{'fields.....'})
(None, {'fields': ('email', 'username', 'password',)}),
('Permissions', {'fields': ('is_staff', 'is_active',)}),
('Personal', {'fields': ('about',)}),
)
add_fieldsets = (
(None, {
'classes': ('wide',),
'fields': ('email', 'password1', 'password2', 'is_staff', 'is_active')}
),
)
search_fields = ('email',)
ordering = ('date_joined',)
admin.site.register(User, UserAdmin)
admin.site.unregister(User)
class UserAdmin(admin.ModelAdmin):
list_display = ['username']
filter_horizontal = ("groups", "user_permissions")
admin.site.register(User, UserAdmin)
