Ich versuche, mithilfe von simple_form eine Tabelle mit wiederkehrenden Abzügen für Mitarbeiter über Kontrollkästchen zu implementieren. Mein Code funktioniert, aber die ausgewählten wiederkehrenden Abzüge werden nicht in meiner Tabelle gespeichert. Ich kann nicht herausfinden warum.

Hier sind meine Modelle.

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

Migration

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

bilden

<%= 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 %>

Regler

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

Hier ist mein bearbeitetes Protokoll
