Sorry for being boring ...
I cannot persuade the UserAdmin to use a custom widget instead of the
one it usually uses. If you can point out where I'm going wrong I will
be indebted to you.
I have tried two ways of using a custom widget ...
1.
https://docs.djangoproject.com/en/2.2/ref/contrib/admin/#django.contrib.admin.ModelAdmin.formfield_overrides
2.
https://docs.djangoproject.com/en/2.2/ref/contrib/admin/#django.contrib.admin.ModelAdmin.formfield_for_manytomany
I think the documentation might be wrong on both the above references.
Or at least I couldn't get either to work so your mileage may vary.
What did work (for me) was the following ...
#common.admin.py (common is my custom-user app)
from django.contrib.auth.admin import UserAdmin
from common.widgets import CommonFilteredSelectMultiple
class CommonUserAdmin(UserAdmin):
def formfield_for_manytomany(self, db_field, request, **kwargs):
if db_field.name == "groups":
formfield = super().formfield_for_manytomany(db_field,
request, **kwargs)
formfield.widget = CommonFilteredSelectMultiple(
db_field.verbose_name,
db_field.name in self.filter_vertical,
)
return formfield
return super().formfield_for_manytomany(db_field, request,
**kwargs)
...
#common.widgets.py
from django.contrib.admin import widgets
class CommonFilteredSelectMultiple(widgets.FilteredSelectMultiple):
def get_context(self, name, value, attrs):
context = super().get_context(name, value, attrs)
context['widget']['attrs']['class'] = 'selectfilter'
if self.is_stacked:
context['widget']['attrs']['class'] += 'stacked'
context['widget']['attrs']['data-field-name'] = self.verbose_name
context['widget']['attrs']['data-is-stacked'] =
int(self.is_stacked)
print("\n20 common.widgets")

Neither of these seem to work for me with a minimally adjusted widget
(see below). This is what I have done ...
#common.widgets.py (my app here is "common")
from django.contrib.admin import widgets
class CommonFilteredSelectMultiple(widgets.FilteredSelectMultiple):
""" If we can only get this to execute we can adjust the context """
def get_context(self, name, value, attrs):
# apart from the print call, this matches FilteredSelectMultiple
print("\n10 admin.widgets")
context = super().get_context(name, value, attrs)
context['widget']['attrs']['class'] = 'selectfilter'
if self.is_stacked:
context['widget']['attrs']['class'] += 'stacked'
context['widget']['attrs']['data-field-name'] = self.verbose_name
context['widget']['attrs']['data-is-stacked'] =
int(self.is_stacked)
return context
