Problem adding user's email in Django admin - django

Question

I created a custom model extending AbstractUser in order to authenticate users by email instad of by username (but not wanting to drop the username, because it will also be used).
This was the first thing I made before running the first migration, everything worked correctly except in the Django admin, when I create a new user, I want these fields to be filled
username
email
password
And the admin only ask me for the username and password. How could I add the email too? Here's my codes
models.py
from django.db import models
from django.contrib.auth.models import AbstractUser
from django.contrib.auth.base_user import BaseUserManager
from django.utils.translation import ugettext_lazy as _
class CustomUserManager(BaseUserManager):
"""
Custom user model manager where email is the unique identifier for
authentication instead of username.
"""
def create_user(self, email, password, **extra_fields):
"""
Create and save a User with the given email and password.
"""
if not email:
raise ValueError(_('The Email must be set'))
email = self.normalize_email(email)
user = self.model(email=email, **extra_fields)
user.set_password(password)
user.save()
return user
def create_superuser(self, email, password, **extra_fields):
"""
Create and save a SuperUser with the given email and password.
"""
extra_fields.setdefault('is_staff', True)
extra_fields.setdefault('is_superuser', True)
extra_fields.setdefault('is_active', True)
if extra_fields.get('is_staff') is not True:
raise ValueError(_('Superuser must have is_staff=True.'))
if extra_fields.get('is_superuser') is not True:
raise ValueError(_('Superuser must have is_superuser=True.'))
return self.create_user(email, password, **extra_fields)
class User(AbstractUser):
email = models.EmailField(_('email address'), unique=True)
USERNAME_FIELD = 'email'
REQUIRED_FIELDS = []
objects = CustomUserManager()
def __str__(self):
return self.email
admin.py
from django.contrib import admin
from django.contrib.auth.admin import UserAdmin
from .models import User as CustomUser
class CustomUserAdmin(UserAdmin):
model = CustomUser
list_display = ('email', 'is_staff', 'is_active',)
list_filter = ('eamil', 'is_staff', 'is_active',)
fieldsets = (
(None, {'fields': ('email', 'password')}),
('Permissions', {'fields': ('is_staff', 'is_active')}),
)
add_fieldsets = (
(None, {
'classes': ('wide',),
'fields': ('email', 'password1', 'password2', 'is_staff', 'is_active')}
),
)
search_fields = ('email',)
ordering = ('email',)
admin.site.register(CustomUser, UserAdmin)
What I have to do? It seems that everything is correct, but the required email field is missing. Notice that this only happens when I use the Add User feature in the admin. When I create a superuser or when I login to the admin, everything is working as expected.
UPDATE:
Here's the content of my forms.py
from django.contrib.auth.forms import UserCreationForm
# the user model was customized it should be invoked
from django.contrib.auth import get_user_model
from django.contrib.auth import forms as auth_forms
from .models import User as CustomUser
class UserChangeForm(auth_forms.UserChangeForm):
class Meta(auth_forms.UserChangeForm.Meta):
model = CustomUser
class UserCreationForm(auth_forms.UserCreationForm):
class Meta(auth_forms.UserCreationForm.Meta):
model = CustomUser
fields = ("username", "email")
class CustomUserCreationForm(UserCreationForm):
class Meta(UserCreationForm.Meta):
# the user model was customized it should be invoked
model = get_user_model()
fields = UserCreationForm.Meta.fields + ("email",)
And here the content (updated) of my admin.py
from django.contrib import admin
from django.contrib.auth.admin import UserAdmin
from .models import User as CustomUser
from .forms import UserChangeForm, UserCreationForm
class CustomUserAdmin(UserAdmin):
model = CustomUser
list_display = ('email', 'username', 'is_staff', 'is_active',)
list_filter = ('eamil', 'username', 'is_staff', 'is_active',)
form = UserChangeForm
add_form = UserCreationForm
fieldsets = (
(None, {'fields': ('email', 'username', 'password')}),
('Permissions', {'fields': ('is_staff', 'is_active')}),
)
add_fieldsets = (
(None, {
'classes': ('wide',),
'fields': ('email', 'username', 'password1', 'password2', 'is_staff', 'is_active')}
),
)
search_fields = ('email',)
ordering = ('email',)
admin.site.register(CustomUser, UserAdmin)
But I still have the same problem, I still can't add an email field in /admin/users/user/add/

Answer 1

The UserAdmin class has the attributes form and add_form which point to form classes to be used to edit and create the user respectively. You need to override these form classes and also set these attributes yourself as these two forms are created for the default user model.
Firstly define these custom forms:
from django.contrib.auth import forms as auth_forms
from .models import User as CustomUser
class UserChangeForm(auth_forms.UserChangeForm):
class Meta(auth_forms.UserChangeForm.Meta):
model = CustomUser
class UserCreationForm(auth_forms.UserCreationForm):
class Meta(auth_forms.UserCreationForm.Meta):
model = CustomUser
fields = ("username", "email")
Next set these in your CustomUserAdmin:
from .forms import UserChangeForm, UserCreationForm
class CustomUserAdmin(UserAdmin):
# Your other attributes here
form = UserChangeForm
add_form = UserCreationForm

Answer 2

In your code, I see
admin.site.register(CustomUser, UserAdmin)
but you have to register through your CustomUserAdmin.
Change your admin.py code to
admin.site.register(CustomUser, CustomUserAdmin)
