Django has truncatewords template tag, which cuts the text at the given word count. But there is nothing like truncatechars.

What's the best way to cut the text in the template at given char-length limit?

This has recently been added in Django 1.4. e.g.:

{{ value|truncatechars:9 }}

Extending the User model with custom fields in Django

The least painful and indeed Django-recommended way of doing this is through a OneToOneField(User) property.

Extending the existing User model

…

If you wish to store information related to User, you can use a one-to-one relationship to a model containing the fields for additional information. This one-to-one model is often called a profile model, as it might store non-auth related information about a site user.

That said, extending django.contrib.auth.models.User and supplanting it also works...

Substituting a custom User model

Some kinds of projects may have authentication requirements for which Django’s built-in User model is not always appropriate. For instance, on some sites it makes more sense to use an email address as your identification token instead of a username.

[Ed: Two warnings and a notification follow, mentioning that this is pretty drastic.]

I would definitely stay away from changing the actual User class in your Django source tree and/or copying and altering the auth module.
