Question

我有这个模型

  class User

  include Mongoid::Document
  authenticates_with_sorcery!
  has_one :user_details 

  field :email , type: String
  field :id_number , type: String
  field :crypted_password , type: String
  field :salt , type: String
  field :fname , type: String
  field :lname , type: String
  field :mname , type: String
end

我想添加一个与此模型的关系

class UserDetails
  include Mongoid::Document

  belongs_to :user

  #fields
  field :year , type: String
  field :block , type: String
  field :course , type: String
  field :alumni , type: Boolean
end

但是当我在表单中使用它时，它表示未定义的方法＆＃39;年＆＃39; 我试过belongs_to：users，has_many：user_detail已经相同了这是在视图中

 =f.text_field :year , placeholder: "Year"

记录错误

Answer 1

错误是说User没有名为'year'的方法，但它没有。 UserDetails的确如此。所以你需要从UserDetails访问年份。
