ajax-datatables-rails как использовать view_columns с одним классом, связанным дважды

Я использую этот драгоценный камень для таблиц данных в рельсах, и у меня возникают проблемы при работе с одной моделью, связанной дважды

https://github.com/jbox-web/ajax-datatables-rails

это моя модель 

class Associate < ActiveRecord::Base
    has_many :missions
    has_many :coordinator_missions, :class_name => "Mission", :foreign_key  => "coordinator_id"
end
class Mission < ActiveRecord::Base
  belongs_to :associate
  belongs_to :coordinator, :class_name => "Associate"
end

Показ данных в таблице работает нормально, но я не могу искать из-за координатора это мой код с датой 

class MissionDatatable < AjaxDatatablesRails::Base


  def view_columns
    @view_columns ||= {
       id: { source: "Mission.id", cond: :eq },
       fy: {source: "Mission.fy"},
       associate_email: {source: "Associate.email"},
       associate_id: {source: "Mission.associate_id"},
       coordinator_email: { source: "Coordinator.email" },
       coordinator_id: { source: "Mission.coordinator_id" },
       name: { source: "Mission.name" },
       fye_output: { source: "Mission.fye_output" },
       status: { source: "Mission.status" },
       created_at: { source: "Mission.created_at" },
       updated_at: { source: "Mission.updated_at" }
    }
  end



  def data
    records.map do |mission|
      {
        # example:
         id: mission.id,
         fy: mission.fy,
         associate_email: mission.associate.email,
         associate_id: mission.associate_id,
         coordinator_email: mission.coordinator.email,
         coordinator_id: mission.coordinator_id,
         name: mission.name,
         fye_output: mission.fye_output,
         status: mission.status,
         created_at: mission.created_at,
         updated_at: mission.updated_at
        }
    end
  end

  private



def get_raw_records
  Mission.joins(:associate).joins(:coordinator)
end


end

Не могли бы вы помочь мне, как сделать правильную настройку для одной модели, связанной дважды? Ошибка в журнале "неверное имя константы"

Похоже, у вас нет константы с именем Coordinator, и согласно документации о связанных моделях вам необходимо использовать имя класса ActiveRecord, Associate, а не Coordinator.
