私は自分のFacebookのフィードにメッセージを投稿するためにfb_graph rails gemを使用しています。fb_graph gemを使ってFacebookのフィード投稿を削除する
私は、次の権限を要求した：
:scope => 'email, publish_actions, offline_access, publish_stream'
私は、ユーザーのフィードに投稿することができています。しかし、私はそれを破壊することはできません。
私はRailsのコンソールで次のコマンドを実行したときにエラーを見ることができます：
me = FbGraph::User.me(user.access_token)
@facebookpost = me.feed!(:message => "sample feed message", :description => 'sample message')
post = me.feed.find(@facebookpost.identifier).first
post.destroy # this generates the following error
