django-email-confirm-la

Django email confirmation for any Model and any Field.

Requirements

• Python (2.6, 2.7, 3.3, 3.4)
• Django (1.4, 1.5, 1.6, 1.7)

Installation

$ pip install django-email-confirm-la

In your settings.py:

Add the email_confirm_la app (put it after your apps) and set the required settings:

INSTALLED_APPS = (
    ...
    'email_confirm_la',
    ...
)

DEFAULT_FROM_EMAIL = '[email protected]'
EMAIL_CONFIRM_LA_HTTP_PROTOCOL = 'http'
EMAIL_CONFIRM_LA_DOMAIN = 'your-domain.com'

If you are using the sites framework, then EMAIL_CONFIRM_LA_DOMAIN can be omitted and Site.objects.get_current().domain will be used.

In your urls.py:

urlpatterns = patterns(
    '',
    url(r'^email_confirmation/', include('email_confirm_la.urls')),
    ...
)

then run

$ python manage.py syncdb
$ python manage.py migrate

Models

For User Model

from django.contrib.auth.models import User
from email_confirm_la.models import EmailConfirmation

user = User.objects.get(username='vinta')
unconfirmed_email = '[email protected]'

email_confirmation = EmailConfirmation.objects.set_email_for_object(
    email=unconfirmed_email,
    content_object=user,
)

For Any Model And Any Field

Assumed you have a model:

from django.db import models
from django.contrib.contenttypes.fields import GenericRelation  # Django 1.7+
from django.contrib.contenttypes.generic import GenericRelation

class YourModel(models.Model):
    ...
    customer_support_email = models.EmailField(max_length=255, null=True, blank=True)
    marketing_email = models.EmailField(max_length=255, null=True, blank=True)
    ...

    # optional, but recommended when you want to perform cascade-deletions
    email_confirmations = GenericRelation('email_confirm_la.EmailConfirmation', content_type_field='content_type', object_id_field='object_id')

And you want to confirm some emails:

from your_app.models import YourModel
from email_confirm_la.models import EmailConfirmation

some_model_instance = YourModel.objects.get(id=42)

email_confirmation = EmailConfirmation.objects.set_email_for_object(
    email='[email protected]',
    content_object=some_model_instance,
    email_field_name='customer_support_email'
)

email_confirmation = EmailConfirmation.objects.set_email_for_object(
    email='[email protected]',
    content_object=some_model_instance,
    email_field_name='marketing_email'
)

Signals

• post_email_confirmation_send
• post_email_confirm
• post_email_save

In your models.py:

from django.dispatch import receiver
from email_confirm_la.signals import post_email_confirm

@receiver(post_email_confirm)
def post_email_confirm_callback(sender, confirmation, **kwargs):
    model_instace = confirmation.content_object
    email = confirmation.email

    do_your_stuff()

Commands

$ python manage.py clear_expired_email_confirmations

Templates

You will want to override the project's email text and confirmation page.

Ensure the email_confirm_la app in INSTALLED_APPS is after the app that you will place the customized templates in so that the django.template.loaders.app_directories.Loader finds your templates before the default templates.

Then copy the templates into your app:

$ cp -R django-email-confirm-la/email_confirm_la/templates/email_confirm_la your_app/templates/email_confirm_la

Finally, modify them:

• email/email_confirmation_subject.txt: Produces the subject line of the email.
• email/email_confirmation_message.html: The HTML body of the email.
• email_confirm_success.html: What the user sees after clicking a confirmation link (on success).
• email_confirm_fail.html: What the user sees after clicking a confirmation link that has expired or is invalid.

Settings

Default values of app settings:

EMAIL_CONFIRM_LA_EMAIL_BACKEND = settings.EMAIL_BACKEND
EMAIL_CONFIRM_LA_HTTP_PROTOCOL = 'http'
EMAIL_CONFIRM_LA_DOMAIN = ''  # remember to override this setting!
EMAIL_CONFIRM_LA_CONFIRM_EXPIRE_SEC = 60 * 60 * 24 * 1  # 1 day
EMAIL_CONFIRM_LA_CONFIRM_URL_REVERSE_NAME = 'confirm_email'
EMAIL_CONFIRM_LA_SAVE_EMAIL_TO_INSTANCE = True
