Django Registration App (originally by POPVOX)

This app provides infrastructure for new user registration including support for social logins (built-in support for Google, Twitter, LinkedIn, and Facebook). For new user accounts using an email address and password, the user is sent a confirmation (verification) email before the account is created.

The email verification routine can be used as an independent app that provides an infrastructure for executing callback routines when a user follows a custom link sent to them in an email. See emailverification/README.txt for details.

Utilities are also provided to manage bounced mail.

Configuration

After cloning this repository, make the registration and emailverification directories available on your Python path. Then install the dependencies:

pip install -r requirements.txt

In settings.py, add to your INSTALLED_APPS:

django.contrib.staticfiles
emailverification
registration

Then set:

APP_NICE_SHORT_NAME = "MySite" # a short name for your site
SERVER_EMAIL = "MySite <noreply@example.org>" # From: address on verification emails
REGISTRATION_ASK_USERNAME = True

If REGISTRATION_ASK_USERNAME is True, then the user is always asked for a username. If False, a username is guessed when enough information is provided by the login provider.

Optionally set:

SITE_ROOT_URL = "http://www.example.org" # canonical base URL of the site, no trailing slash
                                         # The default will be "http://%s" % Site.objects.get_current().domain

Add records to your URLConf like this (you can use any base path):

url(r'^emailverif/', include('emailverification.urls')),
url(r'^registration/', include('registration.urls')),

The registration app provides a new user registration page at /registration/signup.

You will probably also want to use:

url(r'^accounts/login/?$', 'registration.views.loginform'),
url(r'^accounts/logout/?$', 'registration.views.logoutview'),
url(r'^accounts/profile/?$', 'registration.views.profile'),

You will probably want to override the templates in

emailverification/templates/emailverification
    badcode.html: invalid verification code or an error occurred processing it
    expired.htm: expired verification code

by either editing them in place or copying the directories to your site's root templates directory and editing the copies there.

Run python manage.py syncdb to create the necessary database tables.

Beyond this, many of the components of this app are optional. The dependencies and configuration for the optional parts are given next.

Configuring Login Providers

reCAPTCHA on new account creations:

dependencies: python-recaptcha <http://pypi.python.org/pypi/recaptcha-client>

settings.py:

RECAPTCHA_PUBLIC_KEY = "..."
RECAPTCHA_PRIVATE_KEY = "..."

Google login with OpenID:

dependencies: python-openid <https://github.com/openid/python-openid>

No configuration necessary.

Google login with OAuth 1 (not recommended unless you are accessing the user's Google resources):

dependencies: python-oauth2 <http://github.com/simplegeo/python-oauth2>

settings.py:

GOOGLE_OAUTH_TOKEN = "..."
GOOGLE_OAUTH_TOKEN_SECRET = "..."
GOOGLE_OAUTH_SCOPE = "http://www.google.com/m8/feeds/contacts/default/full" # can be an empty string

Twitter login with OAuth 1:

dependencies: python-oauth2 <http://github.com/simplegeo/python-oauth2>

settings.py:

TWITTER_OAUTH_TOKEN = "..."
TWITTER_OAUTH_TOKEN_SECRET = "..."

LinkedIn login with OAuth 1:

dependencies: python-oauth2 <http://github.com/simplegeo/python-oauth2>

settings.py:

LINKEDIN_API_KEY = "..."
LINKEDIN_SECRET_KEY = "..."

Facebook login with OAuth 2:

no dependencies

settings.py:

FACEBOOK_APP_ID = "..."
FACEBOOK_APP_SECRET = "..."
FACEBOOK_AUTH_SCOPE = "email" # can be an empty string

Management

When users register with an email address, they are sent an email to confirm their address. The table that stores state for that should be cleared periodically (e.g. daily) with:

python manage.py clear_expired_email_verifications

Bounced Mail Utility

The emailverification app also contains a utility to check an IMAP mailbox for bounced mail from your site's outgoing mail to registered users.

Send your outbound email with a return path to a special mailbox address that encodes the user ID the message was sent to. For instance, use:

from django.core.mail import EmailMessage
email = EmailMessage(emailsubject, body, "bounces+uid=USER_ID@example.com",
	"user1234@gmail.com", headers = { 'From': "Example Website <feedback@example.com>" })

to specify a return path encoding the recipiens user's id separate from the From: field on the message. Most mail servers ignore the part of an address starting with a plus sign, so you can create an infinite number of virtual addresses. If you use a different address for each user, you can reliably tell who you emailed in message delivery failure emails.

Create an account to receive the mail (e.g. bounces@example.com) that you can access with IMAP. In settings.py, configure access to that inbox:

BOUNCES_IMAP_SSL = True
BOUNCES_IMAP_HOST = 'localhost'
BOUNCES_IMAP_USER = 'bounces'
BOUNCES_IMAP_PASSWORD = '...'

And also configure a regular expression that picks out the user ID from the email address:

BOUNCES_UID_REGEX = re.compile(r"bounces\+uid=(\d+)@example\.com")

Then run:

./manage.py catch_bounces

Which will create an emailverification.BouncedEmail record for each user that a bounced mail was received from, and it will increment a counter for each bounced message. And, it will delete the message from the IMAP server so that you don't count it again the next time you run the management command.

It is up to you to do something with the BouncedEmail records.
