  • email – The recipient’s address.
  • page – The page which will be used to render the email body.
  • extra_context – The context for rendering the page.
password_reset(request, extra_context=None, token_generator=<django.contrib.auth.tokens.PasswordResetTokenGenerator object at 0x31e6950>)

Handles the process by which users request a password reset, and generates the context for the confirmation email. That context will contain:

link
The confirmation link for the password reset.
user
The user requesting the reset.
site
The current Site.
request
The current HttpRequest instance.
Parameters:token_generator – The token generator to use for the confirmation link.
password_reset_confirm(request, extra_context=None, uidb36=None, token=None, token_generator=<django.contrib.auth.tokens.PasswordResetTokenGenerator object at 0x31e6950>)

Checks that token` is valid, and if so, renders an instance of password_set_form with password_set_page.

Parameters:token_generator – The token generator used to check the token.
password_change(request, extra_context=None)

Renders an instance of password_change_form with password_change_page.

class philo.contrib.waldo.models.RegistrationMultiView(*args, **kwargs)

Adds support for user registration to the PasswordMultiView.

register_page

register_confirmation_email

register(request, extra_context=None, token_generator=<philo.contrib.waldo.tokens.RegistrationTokenGenerator object at 0x42dc8d0>)

Renders the register_page with an instance of registration_form in the context as form. If the form has been submitted, sends a confirmation email using register_confirmation_email and the same context as PasswordMultiView.password_reset().

Parameters:token_generator – The token generator to use for the confirmation link.
register_confirm(request, extra_context=None, uidb36=None, token=None, token_generator=<philo.contrib.waldo.tokens.RegistrationTokenGenerator object at 0x42dc8d0>)

Checks that token is valid, and if so, logs the user in and redirects them to post_register_confirm_redirect().

Parameters:token_generator – The token generator used to check the token.
post_register_confirm_redirect(request)

Returns an HttpResponseRedirect for post-registration-confirmation. Default: Node.get_absolute_url() for request.node.

class philo.contrib.waldo.models.AccountMultiView(*args, **kwargs)

Adds support for user accounts on top of the RegistrationMultiView. By default, the account consists of the first_name, last_name, and email fields of the User model. Using a different account model is as simple as replacing account_form with any form class that takes an auth.User instance as the first argument.

manage_account_page

A ForeignKey to the Page which will be used to render the account management form.

email_change_confirmation_email

A ForeignKey to a Page which will be used to render an email change confirmation email. This is optional; if it is left blank, then email changes will be performed without confirmation.

If the form has been posted, the user’s email was changed, and email_change_confirmation_email is not None, sends a confirmation email to the new email to make sure it exists before making the change. The email will have the same context as PasswordMultiView.password_reset().

Parameters:token_generator – The token generator to use for the confirmation link.
has_valid_account(user)

Returns True if the user has a valid account and False otherwise.

account_required(view)

Wraps a view function to allow access only to users with valid accounts and otherwise redirect them to the account_view().

Forms

class philo.contrib.waldo.forms.EmailInput(attrs=None)

class philo.contrib.waldo.forms.RegistrationForm(data=None, files=None, auto_id='id_%s', prefix=None, initial=None, error_class=<class 'django.forms.util.ErrorList'>, label_suffix=':', empty_permitted=False, instance=None)

Handles user registration. If recaptcha_django is installed on the system and recaptcha_django.middleware.ReCaptchaMiddleware is in settings.MIDDLEWARE_CLASSES, then a recaptcha field will automatically be added to the registration form.

recaptcha-django

email = None

An EmailField using the EmailInput widget.

class philo.contrib.waldo.forms.UserAccountForm(user, *args, **kwargs)

Handles a user’s account - by default, auth.User.first_name, auth.User.last_name, auth.User.email.

email_changed()

Returns True if the email field changed value and False if it did not, or if there is no email field on the form. This method must be supplied by account forms used with waldo.

reset_email()

ModelForms modify their instances in-place during _post_clean(); this method resets the email value to its initial state and returns the altered value. This is a method on the form to allow unusual behavior such as storing email on a UserProfile.

classmethod set_email(user, email)

Given a valid instance and an email address, correctly set the email address for that instance and save the changes. This is a class method in order to allow unusual behavior such as storing email on a UserProfile.

class philo.contrib.waldo.forms.WaldoAuthenticationForm(request=None, *args, **kwargs)

Handles user authentication. Checks that the user has not mistakenly entered their email address (like django.contrib.admin.forms.AdminAuthenticationForm) but does not require that the user be staff.

Token generators

Based on django.contrib.auth.tokens. Supports the following settings:

WALDO_REGISTRATION_TIMEOUT_DAYS
The number of days a registration link will be valid before expiring. Default: 1.
WALDO_EMAIL_TIMEOUT_DAYS
The number of days an email change link will be valid before expiring. Default: 1.
philo.contrib.waldo.tokens.registration_token_generator = <philo.contrib.waldo.tokens.RegistrationTokenGenerator object at 0x42dc8d0>

Strategy object used to generate and check tokens for the user registration mechanism.

philo.contrib.waldo.tokens.email_token_generator = <philo.contrib.waldo.tokens.EmailTokenGenerator object at 0x42dc950>
