Mongoid Relation

Question

I have this model

  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

And I want to add a relation to this model

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

but when I used it in my form it says Undefined Method 'year' I tried to belongs_to :users, has_many :user_detail already still the same this is in the view

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

Log Error

Answer 1

The error is saying that User doesn't have a method named 'year', which it doesn't. UserDetails does. So you need to access year from UserDetails.
