CUser, make email the USERNAME\_FIELD
=====================================
CUser makes it easy to use email address as your identification token
instead of a username.
CUser is a custom Django user model (extends ``AbstractBaseUser``) so it
takes a tiny amount of effort to use.
The only difference between CUser and the vanilla Django ``User`` is email
address is the ``USERNAME_FIELD`` (and username does not exist).
CUser supports Django 3.2 - 4.2. If you need to use CUser with
Django 1.8 - 3.1, you must install an older, unmaintained version of
CUser, as noted in the "Install & Set up" section.
Why use CUser?
--------------
Because you want everything in ``django.contrib.auth`` except for the
``username`` field and you also want users to **log in with email addresses**.
And you don't want to create your own custom user model or authentication
backend.
Install & Set up
----------------
**Important:** To keep things simple, the steps below will guide you through
the process of using CUser's ``CUser`` model for your Django project's user
model. However, it is strongly recommended that you set up a custom user model
that extends CUser's ``AbstractCUser`` class, even if CUser's ``CUser`` model
is sufficient for you (this way, you can customize the user model if the need
arises). If you would *not* like to follow this recommendation and just want to
use CUser's ``CUser`` model, simply follow the steps below (you can skip the
rest of this paragraph). If you *would* like to follow this recommendation, you
should still follow the steps below, but with the following adjustments: After
step 3, follow
`these instructions <https://docs.djangoproject.com/en/3.2/topics/auth/customizing/#using-a-custom-user-model-when-starting-a-project>`_,
but instead of using ``from django.contrib.auth.models import AbstractUser``
use ``from cuser.models import AbstractCUser`` and instead of using
``from django.contrib.auth.admin import UserAdmin`` use
``from cuser.admin import UserAdmin``. Then for step 4 of the steps below, you
should set ``AUTH_USER_MODEL`` to your custom user model instead of CUser's
``CUser`` model. You should then run ``python manage.py makemigrations``. After
that, you may follow the remaining steps below just the way they are.
1. If your Django project previously used Django's default user model,
``django.contrib.auth.models.User``, or if you are unfamiliar with using
custom user models, jump to **Notes** first (then come
back). Otherwise, continue onward!
2. Install with ``pip``:
.. code-block:: shell
# Django 3.2 - 4.2
pip install django-username-email
# Django 3.1 (unmaintained)
pip install django-username-email==2.4.2
# Django 2.2 or 3.0 (unmaintained)
pip install django-username-email==2.3.1
# Django 2.0 or 2.1 (unmaintained)
pip install django-username-email==2.2.4
# Django 1.11 (unmaintained)
pip install django-username-email==2.1.6
# Django 1.8 - 1.10 (unmaintained)
pip install django-username-email==2.1.2
3. Add ``cuser`` to your ``INSTALLED_APPS`` setting:
.. code-block:: python
INSTALLED_APPS = [
...
'cuser',
]
4. Specify the custom model as the default user model for your project
using the ``AUTH_USER_MODEL`` setting in your settings.py:
.. code-block:: python
AUTH_USER_MODEL = 'cuser.CUser'
5. If you use Django's default ``AuthenticationForm`` class, it is
strongly recommended that you replace it with the one included with
CUser. This will make the ``<input>`` have its ``type`` attribute set
to ``email`` and browsers' autocomplete feature will suggest email
addresses instead of usernames. For example, if your project is using
Django's default ``LoginView`` view (or ``login`` view in Django < 1.11), this is
what you would put in your urls.py in order to make use of CUser's
``AuthenticationForm`` class:
.. code-block:: python
from cuser.forms import AuthenticationForm
from django.conf.urls import include, url
from django.contrib.auth.views import LoginView
urlpatterns = [
url(r'^accounts/login/$', LoginView.as_view(authentication_form=AuthenticationForm), name='login'),
url(r'^accounts/', include('django.contrib.auth.urls')),
...
]
Or if you're using Django < 1.11:
.. code-block:: python
from cuser.forms import AuthenticationForm
from django.conf.urls import include, url
from django.contrib.auth.views import login
urlpatterns = [
url(r'^accounts/login/$', login, {'authentication_form': AuthenticationForm}, name='login'),
url(r'^accounts/', include('django.contrib.auth.urls')),
...
]
6. Run migrations.
.. code-block:: shell
python manage.py migrate
7. There is a good chance that you want foo@example.com and FOO@example.com to
be treated as the same email address. There is a variety of ways to go about
doing this. How you handle it will depend on the needs of your project and
personal preference, so CUser does not provide a solution for this out of
the box. You will need to address this yourself if this applies to you. If
you're using CUser's ``AuthenticationForm`` class (see step 5), you may want
to subclass it and override ``error_messages['invalid_login']``.
Configuration
-------------
To override any of the default settings, create a dictionary named ``CUSER`` in
your settings.py with each setting you want to override. For example:
.. code-block:: python
CUSER = {
'app_verbose_name': 'Authentication and Authorization',
'register_proxy_auth_group_model': True,
}
These are the settings:
``app_verbose_name`` (default: ``_("Custom User")``)
****************************************************
This controls the value that CUser will use for its ``AppConfig`` class'
``verbose_name``.
``register_proxy_auth_group_model`` (default: ``False``)
********************************************************
When set to ``True``, CUser's admin.py will unregister Django's default
``Group`` model and register its own proxy model of Django's default ``Group``
model (also named ``Group``). This is useful if you want Django's default
``Group`` model to appear in the same part of the admin as CUser's ``CUser``
model.
Notes
-----
If you have tables referencing Django's ``User`` model, you will have to
delete those table and migrations, then re-migrate. This will ensure
everything is set up correctly from the beginning.
Instead of referring to User directly, you should reference the user model
using ``django.contrib.auth.get_user_model()``
When you define a foreign key or many-to-many relations to the ``User``
model, you should specify the custom model using the ``AUTH_USER_MODEL``
setting.
For example:
.. code-block:: python
from django.conf import settings
from django.db import models
class Profile(models.Model):
user = models.ForeignKey(
settings.AUTH_USER_MODEL,
on_delete=models.CASCADE,
)
