Separate button for login & sign up using Facebook.

[Shamim Hasnath]

First of all, thanks for this extra ordinary package.

I was trying to implement facebook connect using FacebookOAuth2.

As far as I understand, If "create_user" pipeline is added, it creates a profile if no matching (e.g. by email) profile exists. Now, I would like to have two buttons.

1. To login user: if account doesn't exist it WILL NOT create a new profile. (Reason: User might have a profile in my site already)

2. To sign up user: if account doesn't exist, it will create a new profile & connect.

Any idea how can I do this?

Thanks in advance.

There's not a direct way to do it, the quick solution that comes to my
mind is:

1. Add a parameter to differentiate the actions, use "/login/facebook"
for login and "/login/facebook?signup=1" for signup.

2. Define this setting:

SOCIAL_AUTH_FIELDS_STORED_IN_SESSION = ['signup']

This setting tells the app to store the query parameter "signup" in
the session (if it's present).

3. Override "create_user" pipeline with this (not tested) version:

from social.pipeline.user import create_user

def custom_create_user(strategy, user=None, *args, **kwargs):
if user is None: # no user discovered
if strategy.session_get('signup'):
# user clicked the "signup" button
return create_user(strategy, user, *args, **kwargs)
else:
# user clicked the "login" button but the account wasn't
# registered (yet)
return redirect('/')
else:
return {'is_new': False}

Makes sense?

Awesome! Thanks @Matías Aguirre. This is exactly what I ended up with. Although I used "FIELDS_STORED_IN_SESSION" as provided in the doc (not tested yet).

I am trying to follow this example to do a similar thing but I keep getting an error when overriding the pipeline. I imported social.pipeline.user without error from the shell, so I am not sure what is going wrong. Here is the code:

from django.shortcuts import redirect

from social.pipeline.user import create_user

def custom_create_user(strategy, user=None, *args, **kwargs):
    if user is None:  # no user discovered

        if strategy.session_get('register'):

            # user clicked the "signup" button

            return redirect('/pd/regerror')
            #return create_user(strategy, user, *args, **kwargs)

        else:
            # user clicked the "login" button but the account wasn't
            # registered (yet)

            return redirect('/pd/regerror')
    else:
        return {'is_new': False}

Here is the error:

Your own module is called "social", that conflicts with the library and fails to import.
