Question

我使用omniauth-facebook并在user.rb中获取有关此功能的用户的信息

def self.find_for_facebook_oauth(auth, signed_in_resource=nil)
  user = User.where(:provider => auth.provider, :uid => auth.uid).first
  unless user
    user = User.create(name: auth.extra.raw_info.first_name,
                       surname: auth.extra.raw_info.last_name,
                       provider: auth.provider,
                       uid: auth.uid,
                       email: auth.info.email,
                       password: Devise.friendly_token[0, 20],
                  #   City: auth.extra.raw_info.location.name,
                      state: auth.extra.raw_info.locale.gsub(/_/, '-'),

                       gender: auth.extra.raw_info.gender,
                       language: auth.extra.raw_info.language|| { },
                       bio: auth.extra.raw_info.bio|| { },
                       work: auth.extra.raw_info.work|| { } ,
                       education: auth.extra.raw_info.education|| { })
    end                   
  user
end

但是auth.extra.raw_info.education|| { }, work: auth.extra.raw_info.work|| { }，给我这样的回复：

  ---
  - !ruby/hash:OmniAuth::AuthHash
  school: !ruby/hash:OmniAuth::AuthHash
  id: '115686675112108'
  name: istituto magistrale
  type: High School
  - !ruby/hash:OmniAuth::AuthHash
  school: !ruby/hash:OmniAuth::AuthHash

  name: laurea in pedagogia

  id: '116957165019970'
  name: '1986'
  type: College

我不知道这是一个数组还是什么，我的教育领域是一个字符串，我如何访问学校，姓名，年份或类型？

如果我尝试auth.extra.raw_info.education.name，则说不可能将整数转换为字符串

Answer 1

如果您正确使用omniauth，则数据应已在内部转换为哈希值（确保auth为env["omniauth.auth"]）

要获得第一个学校名称，请使用：

auth.extra.raw_info.education[0].school.name

ruby on rails登录facebook获取信息
