Question

A fangate is a method to check if user likes the page where the app is, if so, he can view the content.

I’ve been trying for a while to do a fangate with rest-graph gem.

rest_graph_setup(
  :write_session => true,
  :iframe => true,
  :auto_authorize => true,
  :auto_authorize_scope => 'email',
  :app_id        => ENV['FB_ID'],
  :secret        => ENV['FB_SC'],
  :write_cookies => true,
)
raise rest_graph.get('me/likes/PAGE_ID').inspect

Thats the way I connect to the app and get, in theory, the status (/USER_ID/likes/PAGE_ID). But nothing happens, I got an empty array for a PAGE_ID I liked.

I also tried fql method

raise rest_graph.fql('SELECT uid FROM page_fan WHERE page_id=PAGE_ID AND uid=USER_ID').inspect

But again, I get an empty array.

So, any ideas for this?

Looks like you don’t have the user_likes permission in the scope. Add it like

rest_graph_setup(
  :write_session => true,
  :iframe => true,
  :auto_authorize => true,
  :auto_authorize_scope => 'email,user_likes',
  :app_id        => ENV['FB_ID'],
  :secret        => ENV['FB_SC'],
  :write_cookies => true,
)
raise rest_graph.get('me/likes/PAGE_ID').inspect

And that will probably solve your issue
