A Django app providing simple email confirmation.

This app can be used to support three different ways of organizing your Users their email address(es). Each email address can be in a confirmed/unconfirmed state.

  • Users have one email address that is stored on the User
  • Users have one primary email address stored on the User model, and have N secondary emails stored in EmailAddress objects
  • Users have N email addresses stored in EmailAddress objects.

Examples

Create a new User, confirm their email:

.. code:: python

from django.core.mail import send_mail
# ...

email = 'original@here.com'
user = User.objects.create_user(email, email=email)
user.is_confirmed # False

send_mail(email, 'Use %s to confirm your email' % user.confirmation_key)
# User gets email, passes the confirmation_key back to your server

user.confirm_email(user.confirmation_key)
user.is_confirmed # True

Add another email to an existing User, confirm it, then set it as their primary.

.. code:: python

new_email = 'newaddr@nowhere.com'
confirmation_key = user.add_unconfirmed_email(new_email)
new_email in user.unconfirmed_emails # True

send_mail(new_email, 'Use %s to confirm your new email' % confirmation_key)
# User gets email, passes the confirmation_key back to your server

user.confirm_email(confirmation_key)
new_email in user.confirmed_emails # True

user.set_primary_email(new_email)
user.email # newaddr@nowhere.com

Installation

#. From pypi using pip:

.. code:: sh

    pip install django-simple-email-confirmation

#. Add simple_email_confirmation to your settings.INSTALLED_APPS__:

.. code:: python

    INSTALLED_APPS = (
        ...
        'simple_email_confirmation',
        ...
    )

#. Add the provided mixin to your django 1.5+ custom user model__:

.. code:: python

    from django.contrib.auth.models import AbstractUser
    from simple_email_confirmation.models import SimpleEmailConfirmationUserMixin

    class User(SimpleEmailConfirmationUserMixin, AbstractUser):
        pass

Note: you don't strictly have to do this final step. Without this, you won't have the nice helper functions and properties on your `User` objects but the remainder of the app should function fine.

#. Change default settings (optional):

By default, keys don't expire. If you want them to, set `settings.SIMPLE_EMAIL_CONFIRMATION_PERIOD` to a timedelta.

.. code:: python

    from datetime import timedelta

    EMAIL_CONFIRMATION_PERIOD_DAYS = 7
    SIMPLE_EMAIL_CONFIRMATION_PERIOD = timedelta(days=EMAIL_CONFIRMATION_PERIOD_DAYS)

By default, auto-add unconfirmed EmailAddress objects for new Users. If you want to change this behaviour, set `settings.SIMPLE_EMAIL_CONFIRMATION_AUTO_ADD` to False.

.. code:: python

    SIMPLE_EMAIL_CONFIRMATION_AUTO_ADD = False

By default, a length of keys is 12. If you want to change it, set `settings.SIMPLE_EMAIL_CONFIRMATION_KEY_LENGTH` to integer value (maximum 40).

.. code:: python

    SIMPLE_EMAIL_CONFIRMATION_KEY_LENGTH = 16

You are able to override the EmailAddress model provided with this app. This works in a similar fashion as Django's custom user model and allows you to add fields to the EmailAddress model, such as a uuid, or define your own model completely. To set a custom email address model, set `settings.SIMPLE_EMAIL_CONFIRMATION_EMAIL_ADDRESS_MODEL` to the model you would like to use in the <app_label>.<model_name> fashion.

An admin interface is included with simple email confirmation. Although, it is designed to work with the EmailAddress provided. Functionality with the admin cannot be guaranteed when a custom model is used so it is recommended you provide your own admin definition.

Note for existing apps that already use the provided model:

    Similar to Django's custom user model, migrating a custom email address model after the default one is already migrated is not supported and could have unforeseen side effects. The recommendation is to use a custom model from the beginning of development.

.. code:: python

    SIMPLE_EMAIL_CONFIRMATION_EMAIL_ADDRESS_MODEL = 'yourapp.EmailAddress'

Migrating

0.23 to 1.0


A number of backwards incompatible changes are included in the 1.0 release.

- Signal arguments have been refactored. Now, the `email_confirmed`, `unconfirmed_email_created`, and `primary_email_changed` signals send the user class as the `sender` argument and include the user instance as an additional `user` argument. You can update your code as follows:

    .. code:: python

        @receiver(email_confirmed)
        def listener(sender, user, email, **kwargs):
            pass

        @receiver(unconfirmed_email_created)
        def listener(sender, user, email, **kwargs):
            pass

        @receiver(primary_email_changed)
        def listener(sender, user, old_email, new_email, **kwargs):
            pass



Python/Django supported versions
--------------------------------

- Python: 2.7, 3.4, 3.5 and 3.6
- Django: 1.8 to 2.0


Running the Tests
-----------------

#.  Install `tox`__ and `coverage`__

    .. code:: sh

        pip install tox coverage

#.  From the repository root, run

    .. code:: sh

        tox
        tox -e coverage

    It's that simple.
