Django Custom User --- Edit new CustomUser fields in admin

Question

I am trying to expand on the tutorial by William Vincent, posted below:

https://wsvincent.com/django-custom-user-model-tutorial/

I am trying to add new fields to the CustomerUser model I extended via the AbstractUser import from django.contrib.auth.models:

users/models.py:

from django.db import models
from django.contrib.auth.models import AbstractUser, UserManager

class CustomUserManager(UserManager):
    pass

class CustomUser(AbstractUser):
    bio         = models.TextField(max_length=500, blank=True)

    objects = CustomUserManager()

    def __str__(self):
        return self.username

I added the 'bio' field to the model above, but when I access a user via the django admin portal, I don't see the new 'bio' field in there with the default admin fields packaged with django: ie: Personal info: first name, last name, email address, etc.

My CustomUser app is registered to the admin portal like so (following the tutorial mentioned above):

As a test for myself, I was able to display the bio field successfully (showing blank as expected) in my list_display. To reiterate, my problem is I have no way of updating this field when I click to edit a user. The good news is that django picked up the migration of my new 'bio' field.

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

from .forms import CustomUserCreationForm, CustomUserChangeForm
from .models import CustomUser

class CustomUserAdmin(UserAdmin):
    add_form = CustomUserCreationForm
    form = CustomUserChangeForm
    model = CustomUser
    list_display = ['username', 'email','is_staff', 'bio']

admin.site.register(CustomUser, CustomUserAdmin)

My guess is that the solution I am looking for has something to do with editing the admin forms. Here is what I have in my user app (from the tutorial).

users/forms.py:

from django import forms
from django.contrib.auth.forms import UserCreationForm, UserChangeForm
from .models import CustomUser

class CustomUserCreationForm(UserCreationForm):

    class Meta(UserCreationForm):
        model = CustomUser
        fields = ('username', 'email')

class CustomUserChangeForm(UserChangeForm):

    class Meta:
        model = CustomUser
        fields = ('username', 'email')

Admittedly, I don't have a great understanding of what is happening in the form.py file just above. I suspect that it might have nothing to do with the actual user edit form that I am accessing via the admin portal, so I might just need to figure out how to make changes to the default django admin app.

As always, your help is much appreciated, thanks!

Answer 1

The 'fieldsets +' approach is much better than having to write out all the default fields again.

fieldsets = UserAdmin.fieldsets + (
    (None, {'fields': ('some_extra_data',)}),
)
