Question

I have 2 models (Paygrade and Empsal) for 2 controllers (paygrades and empsals)
Here in the form of empsals in view (_form.html.erb)

# PayGrade <%= f.collection_select :pay_grade, Paygrade.all, :id, :title,  
# :prompt => 'Select Paygrade' %>
PayGrade <%= f.collection_select :paygrade, Paygrade.all, :id, :title,  
                :prompt => 'Select Paygrade' %>

Model of Empsal

class Empsal
  include Mongoid::Document
  # field :pay_grade, type: String
  belongs_to :paygrade
  field :salary_component, type: String
  field :pay_frequency, type: String
  field :currency, type: String
  field :amount, type: String
  field :comments, type: String

end

Model of Paygrade

class Paygrade
  include Mongoid::Document
  has_many :empsals # +++++ added
  validates_presence_of :title
  field :title, type: String

end

I want to make the association such that it will save id of paygrade in Empsal for field pay_grade.
But shows the related name of id in view.html.erb
<% empsal.pay_grade %>
what association should be done in model of (Paygrade and Empsal) to get the required output?

Answer 1

class Empsal
  include Mongoid::Document
  belongs_to :paygrade
end
