README.md

django-longer-username provides a migration and a monkeypatch to make the django auth.user username field longer, instead of the arbitrarily short 30 characters.

It's designed to be a simple include-and-forget project that makes a little headache go away. Enjoy, and pull requests welcome!

Usage

Step 1. Install django-longer-username.

• pip install longerusername

You will also need to install south to use the migration.

• pip install south

Step 2. Add longerusername to your installed apps.

Add 'longerusername' to the top of your INSTALLED_APPS in settings.py

settings.py

INSTALLED_APPS = ("longerusername",) + INSTALLED_APPS

Step 3. (Optional) Specify a custom username length

If you want to specify a custom length, add it to settings.py. The default is 255 characters.

settings.py

MAX_USERNAME_LENGTH = 100  # optional, default is 255.

Step 4. Run the migration

$ python manage.py migrate longerusername

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 longerusername.forms import AuthenticationForm

urlpatterns = patterns('',
    # ...
    (r'^accounts/login/$', 'django.contrib.auth.views.login', {'authentication_form': AuthenticationForm}),
)

The monkeypatch for this is very largely based on celement's answer on stackoverflow
