I'm writing facebook canvas application with Rails3 using omniauth-facebook gem. The few moments are not clear:
Rdirect after sing in (in '/auth/facebook/callback' => 'session#create'):
After successful sing_in if user is redirected to root_url it sometime arrives to my canvas page URL (http://localhost:3000) outside of the frame. On other hand, when redirecting him to my app url (http://apps.facebook.com/my_app) it sometime stacks on blank page inside the frame. So how to handle this redirect correctly?What is a proper way to link between pages inside my app? Currently I use relative links and top.location url is always stay my app url (http://apps.facebook.com/my_app). But I saw that many facebook apps redirect the client top.location (http://apps.facebook.com/my_app/internal_link)... It raises one more question:
Now facebook always fetch my app into the iframe using POST method. How to handle this behavior in RESTful rails application?
I'd very thankful for any advices...
