Requirements

• Python (3.5, 3.6, 3.7, 3.8)
• Django (2.0, 2.1, 2.2, 3.0, 3.1)

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 = (
    ...
    'your_app',
    'email_confirm_la',
    ...
)

EMAIL_CONFIRM_LA_HTTP_PROTOCOL = 'https'
EMAIL_CONFIRM_LA_DOMAIN = 'vinta.ws'
EMAIL_CONFIRM_LA_AUTOLOGIN = True
EMAIL_CONFIRM_LA_TEMPLATE_CONTEXT = {
    'THE_ANSWER': 42,
}

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 = [
    ...
    url(r'^email_confirmation/', include('email_confirm_la.urls', namespace='email_confirm_la')),
    ...
]

$ 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')
email = '[email protected]'
EmailConfirmation.objects.verify_email_for_object(email, 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 verify some emails:

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

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

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

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

def post_email_confirmation_confirm_callback(sender, confirmation, **kwargs):

Templates

You will want to override the project's email message and confirmation pages.

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 first.

There are following template that you can override:

• email_confirm_la/email/email_confirmation_subject.txt: Produces the subject line of the email.
• email_confirm_la/email/email_confirmation_message.html: The HTML body of the email.
• email_confirm_la/email_confirmation_success.html: What the user sees after clicking a confirmation link (on success).
• email_confirm_la/email_confirmation_fail.html: What the user sees after clicking a invalid confirmation link.
• email_confirm_la/email_confirmation_expiration.html: What the user sees after clicking an expired confirmation link.
