रेल 4 सरल_फॉर्म चेक बॉक्स के माध्यम से है_many

Question

सहेज नहीं रहा है मैं सरल_फॉर्म का उपयोग करके चेक बॉक्स के माध्यम से एक कर्मचारी आवर्ती कटौती तालिका को लागू करने की कोशिश कर रहा हूं। मेरा कोड काम करता है लेकिन चयनित आवर्ती कटौती मेरी तालिका में सहेजी नहीं जाती है। मैं क्यों काम नहीं कर सकता।

यहां मेरे मॉडल हैं।

class Employee < ActiveRecord::Base 
    belongs_to :club 
    has_many :employee_recurrents 
    has_many :recurrents, :through => :employee_recurrents 
end 

class Recurrent < ActiveRecord::Base 
    belongs_to :club 
    has_many :employee_recurrents 
    has_many :employees, :through => :employee_recurrents 
end 

class EmployeeRecurrent < ActiveRecord::Base 
    belongs_to :employee 
    belongs_to :recurrent 
end 

प्रवास

class CreateEmployeeRecurrents < ActiveRecord::Migration 
    def change 
    create_table :employee_recurrents, :id => false do |t| 

     t.references :employee 
     t.references :recurrent 

    end 

    add_index :employee_recurrents, [:employee_id, :recurrent_id] 
    add_index :employee_recurrents, [:recurrent_id, :employee_id] 

end 
end 

रूप

<%= simple_form_for @employee, html: {class: 'form-horizontal' } do |f| %> 

    <%= f.error_notification %> 

    <%= f.input :first_name %> 
    <%= f.input :last_name %> 

    <%= f.association :recurrents, 
        as: :check_boxes, 
        label_method: :description, 
        value_method: :id, 
        label: 'Recurrent Deductions' %> 

    <%= f.button :submit, class: 'btn btn-primary' %> 
<% end %> 

नियंत्रक

def employee_params 
    params.require(:employee).permit(:first_name, :recurrent_ids) 
end
