I use this gem for datatables in rails and have problem working with one Model associated twice
https://github.com/jbox-web/ajax-datatables-rails
this is my model
class Associate < ActiveRecord::Base has_many :missions has_many :coordinator_missions, :class_name => "Mission", :foreign_key => "coordinator_id"endclass Mission < ActiveRecord::Base belongs_to :associate belongs_to :coordinator, :class_name => "Associate"endShowing data in table works fine, but I cannot search because of Coordinatorthis is my datatable code
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 privatedef get_raw_records Mission.joins(:associate).joins(:coordinator)endendcould you pls help me how to do correct setup for one model associated twice?The error in log is "wrong constant name Coordinator"
