Allow a new user to register an account.
The actual registration of the account will be delegated to the
backend specified by the ``backend`` keyword argument (see below);
it will be used as follows:
1. The backend's ``registration_allowed()`` method will be called,
passing the ``HttpRequest``, to determine whether registration
of an account is to be allowed; if not, a redirect is issued to
the view corresponding to the named URL pattern
``registration_disallowed``. To override this, see the list of
optional arguments for this view (below).
2. The form to use for account registration will be obtained by
calling the backend's ``get_form_class()`` method, passing the
``HttpRequest``. To override this, see the list of optional
arguments for this view (below).
3. If valid, the form's ``cleaned_data`` will be passed (as
keyword arguments, and along with the ``HttpRequest``) to the
backend's ``register()`` method, which should return the new
``User`` object.
4. Upon successful registration, the backend's
``post_registration_redirect()`` method will be called, passing
the ``HttpRequest`` and the new ``User``, to determine the URL
to redirect the user to. To override this, see the list of
optional arguments for this view (below).
**Required arguments**
None.
**Optional arguments**
``backend``
The dotted Python import path to the backend class to use.
``disallowed_url``
URL to redirect to if registration is not permitted for the
current ``HttpRequest``. Must be a value which can legally be
passed to ``django.shortcuts.redirect``. If not supplied, this
will be whatever URL corresponds to the named URL pattern
``registration_disallowed``.
``form_class``
The form class to use for registration. If not supplied, this
will be retrieved from the registration backend.
``extra_context``
A dictionary of variables to add to the template context. Any
callable object in this dictionary will be called to produce
the end result which appears in the context.
``success_url``
URL to redirect to after successful registration. Must be a
value which can legally be passed to
``django.shortcuts.redirect``. If not supplied, this will be
retrieved from the registration backend.
``template_name``
A custom template to use. If not supplied, this will default
to ``registration/registration_form.html``.
**Context:**
``form``
The registration form.
Any extra variables supplied in the ``extra_context`` argument
(see above).
**Template:**
registration/registration_form.html or ``template_name`` keyword
argument.
