How to post additional parameters via JQuery with FullCalendar in Rails? -

i using fullcalendar library adam shaw rails project.

currently, have when click on date, prompts input title event (and possibly other fields later down road) using select callback.

to store events, using sqlite database model event.

i post additional fields (such type:string model not default parameters eventobject in fullcalendar.

for reason works:

// js file associated calendar div $('#calendar').fullcalendar({    ...    select: function(start, end, allday){      var title = prompt('event title:');     if (title){        var eventdata = {         title: title,         description: '',         start: start.format(),         end: end.format(),         url: ''       };        $.ajax({         url: '/events',         type: 'post',         data: {         title: title,         description: '',         start: start.format(),         end: end.format(),         url: '',         type: ''   // <------ can post when it's empty/nil       },          success: function(resp){  // <------ called           alert('success!');           $('#calendar').fullcalendar('renderevent', eventdata, true);          },          error: function(resp){           alert('failure!');         }       });     }     $('#calendar').fullcalendar('unselect');   },  });  

but not when type: non-empty string:

$.ajax({         url: '/events',         type: 'post',         data: {         title: title,         description: '',         start: start.format(),         end: end.format(),         url: '',         type: 'custom'   // <------ gives me alert 'failure!'       },          success: function(resp){           alert('success!');           $('#calendar').fullcalendar('renderevent', eventdata, true);         },          error: function(resp){           alert('failure!');     // <--- called         } }); 

how go posting these non-default fields?

here post , event_params code /events_controller.rb (note: using devise login system, therefore current_tutor retrieves currently-logged in user/tutor; tutor has_many :events , event belongs_to :tutor):

class eventscontroller < applicationcontroller     ...     def create         @tutor = current_tutor         @event = @tutor.events.build(event_params)          respond_to |format|           if @event.save             format.html { redirect_to @event, notice: 'event created.' }             format.json { render :show, status: :created, location: @event }           else             format.html { render :new }             format.json { render json: @event.errors, status: :unprocessable_entity }           end         end     end     ...     def event_params       params[:start_time] = params[:start]       params[:end_time] = params[:end]        params.permit(:title, :description, :start_time, :end_time, :url, :type)     end end 

as testament inexperience , naivety, came realisation data shouldn't contain reserved key used ajax request.

changed type field post_type , worked charm. doh!
