There is one setting that is needed for django-oauth-access:

OAUTH_ACCESS_SETTINGS = {
    'facebook': {
        'keys': {
            'KEY': 'YOURAPPKEY',
            'SECRET': 'yourappsecretcode',
        },
       'endpoints': {
            'authorize': 'https://graph.facebook.com/oauth/authorize',
            'access_token': 'https://graph.facebook.com/oauth/access_token',
            'callback': 'friends.contrib.suggestions.views.import_facebook_contacts',
        },
    },
    'twitter': {
        'keys': {
            'KEY': 'YOURAPPKEY',
            'SECRET': 'yourappsecretcode',
        },
        'endpoints': {
            'request_token': 'https://api.twitter.com/oauth/request_token',
            'authorize': 'http://twitter.com/oauth/authorize',
            'access_token': 'https://twitter.com/oauth/request_token',
            'callback': 'friends.contrib.suggestions.views.import_twitter_contacts',
        },
    },
    'yahoo': {
        'keys': {
            'KEY': 'YOURAPPKEY',
            'SECRET': 'yourappsecretcode',
        },
        'endpoints': {
            'request_token': 'https://api.login.yahoo.com/oauth/v2/get_request_token',
            'authorize': 'https://api.login.yahoo.com/oauth/v2/request_auth',
            'access_token': 'https://api.login.yahoo.com/oauth/v2/get_token',
            'callback': 'friends.contrib.suggestions.views.import_yahoo_contacts',
        },
    },
    'linkedin': {
        'keys': {
            'KEY': 'YOURAPPKEY',
            'SECRET': 'yourappsecretcode',
        },
        'endpoints': {
            'request_token': 'https://api.linkedin.com/uas/oauth/requestToken',
            'authorize': 'https://api.linkedin.com/uas/oauth/authorize',
            'access_token': 'https://api.linkedin.com/uas/oauth/accessToken',
            'callback': 'friends.contrib.suggestions.views.import_linkedin_contacts',
        },
    },
}

Remember to change YOURAPPKEY and yourappsecretcode for each service. You can get them by registering your applications on this sites:

• Facebook: https://developers.facebook.com/apps
• Twitter: https://dev.twitter.com/apps/new
• Yahoo: https://developer.apps.yahoo.com/projects
• LinkedIn: https://www.linkedin.com/secure/developer

Advanced usage

By default friends suggestions are created after each contacts import but there are other situations when you could want to create friends suggestions. One example is when new user is registered on your site. This new user has no imported contacts yet but other users have some imported contacts and maybe new user matches some of the already imported contact. Here is how to create friends suggestions on user activation using some signals:

First create signal receiver:

def find_friends_suggestions(sender, user, **kwargs):
    from friends.contrib.suggestions.models import FriendshipSuggestion
    FriendshipSuggestion.objects.create_suggestions_for_user_using_imported_contacts(user)

If django-easy-userena (or django-userena) app is used for managing users registration use this code:

from userena.signals import activation_complete
activation_complete.connect(find_friends_suggestions, dispatch_uid="find_friends_suggestions_on_activation_complete")

If django-registration app is used use this code:

from registration.signals import user_activated
user_activated.connect(find_friends_suggestions, dispatch_uid="find_friends_suggestions_on_user_activated")
