Question

値データを取得しています: name, uid, highschool_name, Graduateschool_name のように:

def add_friends
    facebook.get_connections("me", "friends", :fields => "name, id, education").each do |hash|
      self.friends.where(:name => hash['name'], 
                         :uid => hash['id'], 
                         :highschool_name => hash['education']['school']['name'] unless hash["education"].blank?,
                         :graduateschool_name => hash['education']['school']['name'] unless hash["education"].blank?).
                   first_or_create
    end
end

ハッシュの配列から:

"education": [
    {
      "school": {
        "id": "110703012290674", 
        "name": "Kunskapsgymnasiet Malmö"
      }, 
      "year": {
        "id": "136328419721520", 
        "name": "2009"
      }, 
      "type": "High School"
    }, 
    {
      "school": {
        "id": "112812485399398", 
        "name": "Malmö University"
      }, 
      "year": {
        "id": "118118634930920", 
        "name": "2012"
      }, 
      "concentration": [
        {
          "id": "104076956295773", 
          "name": "Computer Science"
        }
      ], 
      "type": "Graduate School", 
      "classes": [
        {
          "id": "165093923542525", 
          "name": "Programmering", 
          "description": "Kursen fokuserar på metoder och tekniker vid utveckling av webbapplikationer med hjälp av HTML5."
        }
      ]
    }
  ], 

編集: このコードは機能しません。このハッシュの配列からすべての高校と大学院を選択して保存したいと思います。

Answer 1

high_schools = response['education'].collect{|ed| ed['school']['name'] if ed['type'] == "High School" } 
grad_schools = response['education'].collect{|ed| ed['school']['name'] if ed['type'] == "Graduate School" }
