koalaを使って写真のタグ付けを行う

Last updated at Posted at 2013-02-04

koalaでは写真のアップロードはあってもタグ付けは用意されていません。
なので

put_object

メソッドを使います。

流れとしては、
写真を投稿する -> 投稿した写真のIDを使ってタグ付けする

という流れになります。

graph = Koala::Facebook::API.new(access_token)
result = graph.put_picture("sample.jpg", {:message => "めっせーじ"} )

params = {
  :to => my_friend_id,
  :x  => tags_x,
  :y  => tags_y
}

tags_result = graph.put_object(result["id"], "tags", params)

put_obejtect メソッド を使えば koalaで標準で用意されているメソッド以外にも
拡張してfacebookのGraph API を使うことができます。
