How to Modify Emailfield in AbstractUser Model so that Email is Required - django

Question

How to set emailfield to required when extending AbstractUser?
I was wondering how to override the AbstractUser's emailfield model to set it as required. Currently my form list the email field but does not set as required. By default shouldn't all models be required?
From the documentation it shows an example of how to set a field to required when creating a super user but I am not sure how to complete the task from the AbstractUser model without using AbstractBaseUser.
model.py
from django.db import models
from django.contrib.auth.models import AbstractUser
class CustomUser(AbstractUser):
display_name = models.CharField(max_length=50, unique=True)
bio = models.CharField(max_length=500, blank=True, null=True)
authorization_code = models.CharField(max_length=20)
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', 'display_name', 'authorization_code')
class CustomUserChangeForm(UserChangeForm):
class Meta:
model = CustomUser
fields = ('username', 'email', 'bio')
admin.py
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 = ['email', 'username', 'display_name', 'bio']
list_display_links = ('username', 'display_name')
fieldsets = (
(None, {'fields': ('username', 'display_name', 'email', 'bio', 'password')}),
('Permissions', {'fields': ('is_staff', 'is_active')}),
)
add_fieldsets = (
(None, {
'classes': ('wide',),
'fields': ('username', 'display_name', 'email', 'bio', 'password1', 'password2', 'is_staff', 'is_active')}
),
)
admin.site.register(CustomUser, CustomUserAdmin)
Solution:
# It was as simple as updating my CustomUser model as shown:
class CustomUser(AbstractUser):
display_name = models.CharField(max_length=50, unique=True)
bio = models.CharField(max_length=500, blank=True, null=True)
authorization_code = models.CharField(max_length=20)
email = models.EmailField(max_length=50, unique=True)

You can do it by overriding email in AbstractBaseUser.
from django.contrib.auth.models import AbstractBaseUser, UserManager
class User(AbstractBaseUser):
email = models.EmailField(_('email address'), blank=False)
objects = UserManager()
