Question

我有一个用户类

  class User
  include Mongoid::Document
  include Mongoid::Timestamps

  embeds_one :profile

和班级资料

class Profile
include Mongoid::Document
include Mongoid::Timestamps

embedded_in :user

我使用devise和mongoid来验证用户以及以下方法来存储用户信息：

def self.from_omniauth(auth)
    where(provider: auth.provider, uid: auth.uid).first_or_create do |user|
      user.email = auth.info.email
      user.password = Devise.friendly_token[0,20]
      # Store information in user's profile
      user.profile.first_name = auth['info']['first-name']
      user.profile.last_name = auth['info']['last-name']
      user.profile.profile_picture = auth['info']['picture-url']
      user.profile.linkedin = auth['info']['public-profile-url']
    end
  end

但我总是面临以下错误

未定义的方法`first_name =＆＃39;为零：NilClass

Answer 1

创建一个新的Profile对象，用户作为属性

profile = Profile.create({
  :user => user,
  :first_name => auth['info']['first-name'],
  :last_name => auth['info']['last-name'], ....})

使用Devise an Mongoid在身份验证期间创建Mongoid中对象创建的嵌入文档
