Nested attributes in mongodb confusion - ruby-on-rails

Question

I am using rails with database Mongodb.
I am using devise . Devise has model name user.The id of the user is in
:id => current_user.id
I want to make a model such that when data is save from the form the id of the current user will also save in the collection.
The model of my employee is
class Employee
include Mongoid::Document
field :first_name, type: String
field :middle_name, type: String
field :last_name, type: String
field :otherid, type: String
field :licennum, type: String
field :citizennum, type: String
field :licenexp, type: String
field :gender, type: String
field :state, type: String
field :marital_status, type: String
field :country, type: String
field :birthdate, type: String
field :nickname, type: String
field :description, type: String
validates_presence_of :first_name
{
}
end
what should i put inside curly bracket so that when data is saved from that model it saves the current user id also inside it?

Answer 1

The code you show only contains personal information fields like birth date and such. I suppose the simplest solution would be to place them inside the User class, and change them using built-in devise actions such as devise/registrations#edit, which applies the changes to current_user as default.
Alternatively, if you want to keep Employee as a separate class, you could try embedding Employee in User class, like this:
class User
include Mongoid::Document
embeds_one :employee
(...)
class Employee
include Mongoid::Document
embedded_in :user
In this case, you would set up the relation at controller level, e.g.:
class EmployeesController < ApplicationController
def create
current_user.create_employee(params[:employee])
end
After creation, you could access the user's ID from Employee class as user.id.
