Base form classes

Several form classes are provided with django-registration, covering common cases for gathering account information and implementing common constraints for user registration. These forms were designed with django-registration‘s built-in registration workflows in mind, but may also be useful in other situations.

class registration.forms.RegistrationForm

A simple form for registering an account. This is a subclass of Django’s built-in UserCreationForm, and has the following fields, all of which are required:

username
The username to use for the new account. This is represented as a text input which validates that the username is unique, consists entirely of alphanumeric characters and underscores and is at most 30 characters in length.
email
The email address to use for the new account. This is represented as a text input which accepts email addresses up to 75 characters in length.
password1
The password to use for the new account. This is represented as a password input (input type="password" in the rendered HTML).
password2
The password to use for the new account. This is represented as a password input (input type="password" in the rendered HTML).

Because this is a subclass of Django’s own UserCreationForm, the constraints on usernames and email addresses match those enforced by Django’s default authentication backend for instances of django.contrib.auth.models.User. The repeated entry of the password serves to catch typos.

The validation error for mismatched passwords is attached to the password2 field. This is a backwards-incompatible change from django-registration 1.0.

class registration.forms.RegistrationFormTermsOfService

A subclass of RegistrationForm which adds one additional, required field:

tos
A checkbox indicating agreement to the site’s terms of service/user agreement.
class registration.forms.RegistrationFormUniqueEmail

A subclass of RegistrationForm which enforces uniqueness of email addresses in addition to uniqueness of usernames.

class registration.forms.RegistrationFormNoFreeEmail

A subclass of RegistrationForm which disallows registration using addresses from some common free email providers. This can, in some cases, cut down on automated registration by spambots.

By default, the following domains are disallowed for email addresses:

  • aim.com
  • aol.com
  • email.com
  • gmail.com
  • googlemail.com
  • hotmail.com
  • hushmail.com
  • msn.com
  • mail.ru
  • mailinator.com
  • live.com
  • yahoo.com

To change this, subclass this form and set the class attribute bad_domains to a list of domains you wish to disallow.
