if you are using the Koala Gem just use:

#check wether wallpost is allowed
permissions = graph.get_connections('me','permissions')
@has_wallpost_permission = permissions.select{|o| o['permission'] == 'manage_pages'}.length == 1

  • That's half of it but how do you tell Koala to request certain permissions from the user when they authorise the app? – Dave Sag Aug 27 '12 at 02:25

If you don't use Koala you can send request 'GET /{user-id}/permissions' This is described in 'Checking Current Permissions' section here https://developers.facebook.com/docs/facebook-login/permissions/v2.1

You must autorize user with publish_stream permission. In rails I do it with OmniAuth gem.

  • The scenario is the user has authorize the app. I want to check if the user given certain permission to my app. if not I want to take that permission. Is this possible in facebook graph API or in rails 3. My app is running in facebook canvas. – AliZubi Nov 18 '11 at 08:14
  • You can use FQL query to [check permission](http://developers.facebook.com/docs/reference/fql/permissions/) – super_p Nov 18 '11 at 12:33
