Extending default user using Abstract User - django

Question

I am trying to add some extra fields in default user model. But the new fields is not showing up in admin page. Here are the models of 'users' app.
models.py
from django.db import models
from django.contrib.auth.models import AbstractUser
class CustomUser(AbstractUser):
q1 = models.TextField()
q2 = models.TextField()
forms.py
from django import forms
from django.contrib.auth.forms import UserCreationForm, UserChangeForm
from .models import CustomUser
class CustomUserCreation(UserCreationForm):
class Meta(UserCreationForm.Meta):
model = CustomUser
fields = ('username', 'email', 'q1', 'q2')
class CustomUserChange(UserChangeForm):
class Meta:
model = CustomUser
fields = ('username', 'email', 'q1', 'q2')
admin.py
from django.contrib import admin
from django.contrib.auth.admin import UserAdmin
from .forms import CustomUserCreation, CustomUserChange
from .models import CustomUser
class CustomUserAdmin(UserAdmin):
add_form = CustomUserCreation
form = CustomUserChange
list_display = ['email', 'username', 'password', 'q1', 'q2']
model = CustomUser
admin.site.register(CustomUser, CustomUserAdmin)
P.S. I have added AUTH_USER_MODEL = users.CustomUser in settings.py

Answer 1

In your admin.py file you need to override UserAdmin as:
class CustomUserAdmin(BaseUserAdmin):
form = CustomUserChange
add_form = CustomUserCreation
list_display = ('email', 'username', 'password', 'q1', 'q2')
fields = ('email', 'username', 'password', 'q1', 'q2')
model = CustomUser
admin.site.register(CustomUser, UserAdmin)
Check this example in the docs for more understanding link

Answer 2

Please check the following things into your django project.
Have you added AUTH_USER_MODEL = 'users.models.CustomUser' to your settings.py file ?
Ensure you have added q1 and q2 to your fields attribute in CustomUserAdmin as follow:
class CustomUserAdmin(UserAdmin):
add_form = CustomUserCreation
form = CustomUserChange
list_display = ['email', 'username', 'password', 'q1', 'q2']
fields = ['email', 'username', 'password', 'q1', 'q2']
model = CustomUser

Answer 3

You can just create a user profile model with a OneToOne relation and fire it up using signal whenever a user has been added without having to touch the User model.
from django.db.models.signals import post_save
from django.dispatch import receiver
from django.contrib.auth.models import User
class Profile(models.Model):
user=models.OneToOneField(User, on_delete=models.CASCADE)
q1 = models.TextField()
q2 = models.TextField()
def __unicode__(self):
return self.user.q1
def create_profile(sender, **kwargs):
user = kwargs["instance"]
if kwargs["created"]:
user_profile = Profile(user=user)
user_profile.save()
post_save.connect(create_profile, sender=User)
