django-longerusernameandemail
provides a migration and a monkeypatch to make the Django auth.user username and email fields longer, instead of the arbitrarily short 30 and 75 characters. It's designed to be a simple include-and-forget project that makes a little headache go away. Enjoy, and pull requests welcome!
Note that Django 1.5 or newer already includes support for custom User
models (read this tutorial and the official documentation about Substituting a custom User model). So, you only need django-longerusernameandemail
if you use an older Django version, or if you don't want to create your own User model for some reason.
Usage
Step 1. Install django-longerusernameandemail.
pip install django-longerusernameandemail
You will also need to install south to use the migration.
pip install south
longerusernameandemail
to your installed apps.
Step 2. Add Add 'longerusernameandemail' to the top of your INSTALLED_APPS
in settings.py
settings.py
INSTALLED_APPS = ("longerusernameandemail",) + INSTALLED_APPS
Step 3. (Optional) Specify a custom username length, or other settings.
If you want custom behavior, you can specify the following in settings.py
settings.py
MAX_USERNAME_LENGTH = 100 # optional, default is 255.
MAX_EMAIL_LENGTH = 50 # optional, default is 255.
REQUIRE_UNIQUE_EMAIL = False # optional, default is True
Step 4. Run the migration
$ python manage.py migrate longerusernameandemail
That's it, you should be good to go!
Notes about the built-in forms
This app also automatically monkey patches the User forms in the Django admin to remove the 30 character limit.
It provides a suitable replacement for the standard AuthenticationForm as well, but due to the implementation you must manually utilize it.
urls.py
from longerusernameandemail.forms import AuthenticationForm
urlpatterns = patterns('',
# ...
(r'^accounts/login/$', 'django.contrib.auth.views.login', {'authentication_form': AuthenticationForm}),
)
