Custom user model for Django with the same behaviour as the default User class but with email instead of username.

Project description

PyPI version GitHub Actions Workflow Status (main branch) https://img.shields.io/pypi/dm/django-custom-user.svg

Custom user model for Django with the same behaviour as the default User class but without a username field. Uses email as the USERNAME_FIELD for authentication.

Quick start

  1. Install django-custom-user with your favorite Python package manager:

pip install django-custom-user
  1. Add 'custom_user' to your INSTALLED_APPS setting:

INSTALLED_APPS = (
    # other apps
    'custom_user',
)
  1. Set your AUTH_USER_MODEL setting to use EmailUser:

AUTH_USER_MODEL = 'custom_user.EmailUser'
  1. Create the database tables:

python manage.py migrate

Usage

Instead of referring to EmailUser directly, you should reference the user model using get_user_model() as explained in the Django documentation. For example:

from django.contrib.auth import get_user_model

user = get_user_model().objects.get(email="user@example.com")

When you define a foreign key or many-to-many relations to the EmailUser model, you should specify the custom model using the AUTH_USER_MODEL setting. For example:

from django.conf import settings
from django.db import models

class Article(models.Model):
    author = models.ForeignKey(settings.AUTH_USER_MODEL)

Extending EmailUser model

You can easily extend EmailUser by inheriting from AbstractEmailUser. For example:

from custom_user.models import AbstractEmailUser

class MyCustomEmailUser(AbstractEmailUser):
    """
    Example of an EmailUser with a new field date_of_birth
    """
    date_of_birth = models.DateField()

Remember to change the AUTH_USER_MODEL setting to your new class:

AUTH_USER_MODEL = 'my_app.MyCustomEmailUser'

If you use the AdminSite, add the following code to your my_app/admin.py file:

from django.contrib import admin
from custom_user.admin import EmailUserAdmin
from .models import MyCustomEmailUser


class MyCustomEmailUserAdmin(EmailUserAdmin):
    """
    You can customize the interface of your model here.
    """
    pass

# Register your models here.
admin.site.register(MyCustomEmailUser, MyCustomEmailUserAdmin)

Changelog

Version 1.0 (2022-03-29)

After a long hiatus, this new version brings compatibility with the latest Django and Python versions, among lots of small improvements and cleanups.

  • Supported versions:

    • Django: 3.2 LTS, 4.0

    • Python: 3.7, 3.8, 3.9, 3.10

  • Import latest code changes from Django 4.0 (#65):

    • EmailUserCreationForm does not strip whitespaces in the password fields, to match Django’s behavior.

    • EmailUserCreationForm supports custom password validators configured by AUTH_PASSWORD_VALIDATORS.

    • EmailUser.objects.create_superuser() allows empty passwords. It will also check that both is_staff and is_superuser parameters are True (if passed). Otherwise, it would create an invalid superuser.

  • Internal changes:

    • Moved away from Travis CI to Github Actions.

    • Build system and dependencies managed with Poetry.

    • Code formatted with black and isort.

Note that older versions of Django are not supported, but you can use the previous version 0.7 if you need it.

Version 0.7 (2017-01-12)

  • Fixed change password link in EmailUserChangeForm (thanks to Igor Gai and rubengrill)

Version 0.6 (2016-04-03)

  • Added migrations (thanks to everybody for the help).

How to apply the migrations after upgrading:

Django 1.7

For this version just run the following commands.

python manage.py migrate custom_user 0001_initial_django17 --fake
python manage.py migrate custom_user

Django 1.8

This version didn’t work without migrations, which means that your migrations will conflict with the new ones included in this version.

If you added the migrations with Django’s MIGRATION_MODULES setting, delete the folder containing the migration modules and remove the setting from your config.

If you just ran python manage.py makemigrations, the migrations are located inside your system’s or virtualenv’s site-packages folder. You can check the location running this command, and then delete the folder migrations that is inside:

python -c "import os; import custom_user; print(os.path.dirname(custom_user.__file__))"

You can check if you have removed the migrations successfully running this command, you shouldn’t see the section custom_user anymore:

python manage.py migrate --list

Once the old migrations are gone, run the following command to finish:

python manage.py migrate custom_user 0002_initial_django18 --fake
