Question

OmniAuth FaceBook登录我的webapp时遇到了一些问题。请告诉我，我应该编辑什么来修复此错误？检查代码。

浏览器出错：

未定义的方法`to_a＆＃39; for＆＃34; Name Surname＆＃34;：String

User.rb：

def self.from_omniauth(auth)
    where(provider: auth.provider, uid: auth.uid).first_or_create do |user|
      x = auth.info.name.to_a
      user.name = x[0]
      user.surname = x[1]
      user.login = auth.info.uid
      user.email = auth.info.email
      user.password = Devise.friendly_token[0,20]

    end
  end

Omniauth_callback_controller.rb：

def facebook
    if request.env["omniauth.auth"].info.email.blank?
      redirect_to "/users/auth/facebook?auth_type=rerequest&scope=email"
    end
    @user = User.from_omniauth(request.env["omniauth.auth"])
    if @user.persisted?
      sign_in_and_redirect @user, :event => :authentication #this will throw if @user is not activated
      set_flash_message(:notice, :success, :kind => "Facebook") if is_navigational_format?
    else
      session["devise.facebook_data"] = request.env["omniauth.auth"]
      if(@user.surname.nil?)
        redirect_to new_profile_path
      else
        redirect_to my_profile_path
      end
    end
  end

devise.rb：

config.omniauth :facebook, '*********', '*********', {:client_options => {:ssl => {:verify => false}}}

Answer 1

name是一个字符串，您正在尝试将其转换为数组

x = auth.info.name.to_a

使用split代替

x = auth.info.name.split
#=> ['Name', 'Surname']

Answer 2

您可以使用OmniAuth first_name和last_name：

更新你的devise.rb：

config.omniauth :facebook, '*********', '*********', info_fields: 'email, first_name, last_name', {:client_options => {:ssl => {:verify => false}}}

和你的user.rb：

def self.from_omniauth(auth)
    where(provider: auth.provider, uid: auth.uid).first_or_create do |user|

      user.name = auth.info.first_name
      user.surname = auth.info.last_name
      user.login = auth.info.uid
      user.email = auth.info.email
      user.password = Devise.friendly_token[0,20]

    end
  end

Answer 3

你的user.rb应该是这样的

def self.from_omniauth(auth)
    where(provider: auth.provider, uid: auth.uid).first_or_create do  |user|
      x = auth.info.name.split
      if x.count > 1
        user.name = x[0]
        user.surname = x[1]
      else
        user.name = x[0]
      end 
      user.login = auth.info.uid
      user.email = auth.info.email
      user.password = Devise.friendly_token[0,20]
    end
end

但我建议将其存储在一个字段中，因为名称可能超过两个字，因此很难识别名字和姓氏。
