Form enhancement
================

In order to be able to register users with newsletter functionality using
django-mailchimp-forms you have 3 options:

1. The default form:

The default form contains fields for: *username*, *password*, *password
confirmation*, *email*, *newsletter*. (In fact it is a
django.contrib.auth.forms.UserCreationForm wrapped with the django-mailchimp-forms
form wrapper).

It is used in a view like this:

::

from django_mailchimp_forms.forms import ChimpyForm

def register(request):
if request.method == 'POST':
form = ChimpyForm(request.POST)
if form.is_valid():
newuser = form.save()
return HttpResponseRedirect('profile_page', user_id=newuser.id)
else:
form = ChimpyForm()
return render_to_response('register.html', {'form': form})

2. The form class wrapper:

You can use this if you have already defined a form for registration or if you
are currently using a registration form from another django app
(django-registration, django-userprofile, etc). The only requirement of the
initial form is that it defines a 'save' method that creates and returns the
newly created User instance.

::

from registration import RegistrationForm
from django_mailchimp_forms.forms import chimpy_form_class_wrapper

form_class = chimpy_form_class_wrapper(RegistrationForm)
def register(request):
if request.method == 'POST':
form = form_class(request.POST)
if form.is_valid():
newuser = form.save()
return HttpResponseRedirect('profile_page', user_id=newuser.id)
else:
form = form_class()
return render_to_response('register.html', {'form': form})

3. The form instance wrapper:

If you are already use a form instance you can 'enhance' it as well with
newsletter capabilities. Note: the wrapper function takes a second optional
'data' argument that should be the POST dictionary in case the form is supposed
to be bound to post data.

::

from registration import RegistrationForm
from django_mailchimp_forms import chimpy_form_instance_wrapper

def register(request):
if request.method == 'POST':
form = RegistrationForm(request.POST)
form = chimpy_form_instance_wrapper(form, request.POST)
if form.is_valid():
newuser = form.save()
return HttpResponseRedirect('profile_page', user_id=newuser.id)
else:
form = form_class()
form = chimpy_form_instance_wrapper(form)
return render_to_response('register.html', {'form': form})

Views
=====

There are 2 views, one to register a user to a mailing list and one to
unregister. The views require HTTP POST request methods and support both AJAX
and non-AJAX requests. In the case of an AJAX request, the view will return a
JSON string with 'success'(boolean) and 'message'(string) attributes while in
the case of a non-AJAX request, the view will redirect to the path designated
by the 'next' GET variable and an appropriate message will be added to the
relevant user's message set.
