This error occurs in the Admin for my custom user when I try to
specify a custom widget for permission groups. I haven't included
'groups' in any raw_id_fields, radio_fields or autocomplete_fields.
The groups are correctly displayed in the Admin user page with the
default FilteredSelectMultiple widget.
This is the relevant code in admin.py ... (traceback below)
class CommonUserAdmin(UserAdmin):
model = get_user_model()
def formfield_for_manytomany(self, db_field, request, **kwargs):
if db_field.name == "groups":
formfield_overrides = {
models.ManyToManyField: {'widget':
CommonFilteredSelectMultiple},
}
...
If I omit the formfield_for_manytomany() method and just run
formfield_overrides nakedly nothing happens - presumably because the
admin doesn't consider "groups" is a ManyToManyField at that point.
How do I persuade the Admin to use my widget?
Thanks for any advice
Mike
