ruby on rails - Sortable Table Row with Nested Resource -


in rails app, timesheet has_many entries , entry belongs_to timesheet.

class timesheet < activerecord::base   has_many :entries, order: 'position', dependent: :destroy end   class entry < activerecord::base   belongs_to :timesheet end

i'm following railscast 147 sortable lists (the updated version). in development log notice params hash correctly updates sort order, on reload doesn't save positions correctly. furthermore, request being processed create action instead of custom sort action. here's controller. 

class entriescontroller < applicationcontroller   before_filter :signed_in_user   before_filter :find_timesheet    def index     @entries = @timesheet.entries.order("position")     @entry = @timesheet.entries.build   end    def create     @entry = @timesheet.entries.build(params[:entry])     @entry.position = @timesheet.entries.count + 1     if @entry.save       #flash[:notice] = "entry created"       #redirect_to timesheet_entries_path       respond_to |format|         format.html { redirect_to timesheet_entries_path }         format.js       end     else       flash[:alert] = "entry not added"       render 'new'     end   end    def destroy     @entry = @timesheet.entries.find(params[:id])     @entry.destroy     respond_to |format|       format.html { redirect_to timesheet_entries_path, flash[:notice] = "entry destroyed" }       format.js     end   end    def sort     params[:entry].each_with_index |id, index|       @timesheet.entries.update_all({position: index+1}, {id: id})     end     render nothing: true   end    private      def find_timesheet       @timesheet = timesheet.find(params[:timesheet_id])     end   end

and routes.rb file. 

sledsheet::application.routes.draw    resources :timesheets     resources :entries, only: [:index, :create, :destroy]       collection { post :sort }     end   end end

the entries.js.coffee

jquery ->      $("#entries tbody").sortable(         helper: fixhelper         update: ->             $.post($(this).data('update-url'), $(this).sortable('serialize'))     ).disableselection()

the output development log

started post "/timesheets/8/entries" 127.0.0.1 @ 2012-06-04 20:14:18 -0400 processing entriescontroller#create */*   parameters: {"entry"=>["60", "59", "61"], "timesheet_id"=>"8"}   user load (0.2ms)  select "users".* "users" "users"."remember_token" = 'qds53hgowfrmbnn9jkau3w' limit 1   timesheet load (0.1ms)  select "timesheets".* "timesheets" "timesheets"."id" = ? order date desc limit 1  [["id", "8"]] completed 500 internal server error in 2ms  nomethoderror (undefined method `stringify_keys' "60":string):   app/controllers/entries_controller.rb:11:in `create'

i googled error undefined method, i'm confused why create action called in case anyway? have new_entry form on page, creates new entry via ajax. perhaps interfering sort? appreciated!

the reason why there's no 'stringify_keys' method because you're passing array create action , not sort action. have data-update-url in erb.html file? should sort_entries_path.
