使用Omniauth-Facebook gem存储user_likes

Question

Does anyone know where in the Auth Hash the user_likes are stored?

I've tried different combos:

auth.extra.raw_info.user_likes
auth.extra.raw_info.likes

I've got the permission, I just don't know how to get to the user_likes array.

Omniauth-Facebook gem

After some time (edit)

Alternatively I could do something like this using the HTTParty gem:

  url = "https://graph.facebook.com/#{auth.uid}/likes&access_token=#{auth.credentials.token}"
  @likes = HTTParty.get(url)

But I really want to know if its possible through the omniauth authentication process...

Answer 1

The omniauth-facebook gem uses the /me call to fill the raw_info hash. Per the facebook docs http://developers.facebook.com/docs/reference/api/user/ , likes are not included in the user object but are a connection that can be accessed by calling https://graph.facebook.com/me/likes .

Answer 2

Hope this response though late, helps someone who is trying to figure out what is inside the different hashes part of auth hash object (schema reference: https://github.com/intridea/omniauth/wiki/Auth-Hash-Schema )

Instead of trying different combinations (as posted in the question), one could simply render the object as an yaml to browser. Now page source of the browser output would give a clear picture of what is returned part of the auth object. Other option is to put a debug break and inspect the auth object in the callback controller (an ide would be very helpful in this case).

routes.rb

 ...
 match '/auth/facebook/callback' => 'authentications#create'
 ...

authentications_controller.rb (or your controller that receives the call back)

class AuthenticationsController < ApplicationController
    ...


    def create
        # a simple code to understand the content of the auth object
        render :text => request.env["omniauth.auth"].to_yaml
    end
 end
