python-social-auth backend not found for linkedin oauth2

Question

I am trying to incorporate linkedin oauth2 in my app using python-social-auth. However, when i navigate to 127.0.0.1:8000/login/linkedin/ in Chrome I get a "Backend not found" error. Specifically, the logs display the following errors:

[08/Sep/2014 16:44:38] "GET /login/linkedin HTTP/1.1" 301 0
[08/Sep/2014 16:44:38] "GET /login/linkedin/ HTTP/1.1" 404 1608

I have the following related code in my settings.py:

INSTALLED_APPS = (
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'github_app',
    'tech_seeker',
    'social.apps.django_app.default'
)

SOCIAL_AUTH_LINKEDIN_OAUTH2_KEY = "<MY_KEY_HERE>"
SOCIAL_AUTH_LINKEDIN_OAUTH2_SECRET = "<MY_SECRET_HERE>"

SOCIAL_AUTH_STRATEGY = 'social.strategies.django_strategy.DjangoStrategy'

AUTHENTICATION_BACKENDS = (
    'social.backends.linkedin.LinkedinOAuth2',
    'django.contrib.auth.backends.ModelBackend',
)

SOCIAL_AUTH_PIPELINE = (
    'social.pipeline.social_auth.social_details',
    'social.pipeline.social_auth.social_uid',
    'social.pipeline.social_auth.auth_allowed',
    'github_app.auth_pipeline.user'
)

Any help is appreciated.

If you are using social.backends.linkedin.LinkedinOAuth2the url must be http://localhost:8000/login/linkedin-oauth2/: <a href="{% url 'social:begin' 'linkedin-oauth2' %}">Login</a> For social.backends.linkedin.LinkedinOAuth it's http://localhost:8000/login/linkedin/: <a href="{% url 'social:begin' 'linkedin' %}">Login</a> – Retrogressive

I am also having the same problem. please help me if you have got the solution – Review

Answer 1

Because you use OAUTH2 you need to change you url for using oauth2.

<a href="{% url 'social:begin' backend='linkedin-oauth2' %}">LinkedIn</a>

There's a list of backends here, a few examples of the django apps here, but is there a complete list of backends and url names somewhere or a way to work it out? – Northwesterly

No, you can only look inside every backend at github.com/omab/python-social-auth/blob/master/social/backends for "name" value – Plunkett

Thanks, I found the documentation to be really lacking here. – Grimm
