Social log in only

[rjbriody]

It would be awesome if it were possible to log in w/ a social account only. Meaning there would be no need to enter email or passwords.

Apparently others are looking for this as well (I did not create this stack post): http://stackoverflow.com/questions/17998627/using-flask-social-with-oauth-providers-only-no-local-registration-login-form

Hey @rjbriody. This is doable without too much extra work using the @login_failed.connect_via decorator. With app as your instance of a Flask app, it would look like

@login_failed.connect_via(app):
def on_login_failed(sender, provider, oauth_response):
    connection_values = get_connection_values_from_oauth_response(provider, oauth_response)
    ds = current_app.security.datastore
    user = ds.create_user( ... ) #fill in relevant stuff here
    ds.commit()
    connection_values['user_id'] = user.id
    connect_handler(connection_values, provider)
    login_user(user)
    db.commit()
    return render_template('success.html')

As for filling in the relevant stuff for creating the user, I just create a random string for the password, and haven't had issues leaving the email null. Hope that helps!

Hey this is way better than the ugly hack I made. I'm excited to try it out. Thanks!

@rjbriody @eriktaubeneck Just wondering if you guys wrote a tutorial somewhere about how to do this (a small complete application). Would be a nice tutorial for beginners like me. :)

This really should be in the docs!
