django-newsletter-subscription

Another newsletter subscription app.

Subscription flow

• User enters his/her email address on /newsletter/.
• A mail is sent to the given address containing a link of the form /newsletter/s/<signed_email_address>/.
• Upon visiting the link the user is immediately subscribed for the newsletter. Optionally, a form asking the user for additional data is shown.

Unsubscription flow

• The user enters his/her email address on /newsletter/ and is immediately unsubscribed.
• An email is sent to the user informing him/her that the unsubscription took place. A link is provided to immediately subscribe again in case the unsubscription was not meant to take place. The link is of the form /newsletter/r/<signed_email_address>/.

Subscription model

The minimal set of database fields is as follows:

• email (EmailField, unique)
• is_active (BooleanField, defaults to False)

Usage

This example assumes you are using at least Django 1.4.

1. Install django-newsletter-subscription using pip.

2. Add a concrete model inheriting newsletter_subscription.models.SubscriptionBase with optionally additional fields about the subscription. You should be prepared to work without those additional fields -- their presence is not enforced as per the subscription flow description above. A full example:

   from django.db import models
   from django.utils.translation import ugettext_lazy as _
   
   from newsletter_subscription.models import SubscriptionBase
   
   class Subscription(SubscriptionBase):
       full_name = models.CharField(_('full name'), max_length=100, blank=True)

3. Add the URLconf entry:

   from .newsletter.models import Subscription
   
   from newsletter_subscription.backend import ModelBackend
   from newsletter_subscription.urls import newsletter_subscriptions_urlpatterns
   
   urlpatterns += patterns(
       '',
       url(
           r'^newsletter/',
           include(newsletter_subscriptions_urlpatterns(
               backend=ModelBackend(Subscription),
           )),
       ),
   )

4. Register your own subscription model with django.contrib.admin.

5. Add newsletter_subscription to INSTALLED_APPS if you want to use the bundled templates. The templates require Towel's towel_form_tags template tag library.

6. Ensure that Django's messages framework is activated and that the messages are included in your templates, otherwise the notifications from django-newsletter-subscriptions will not be shown to the users.
