Question

I am iterating over a moment-range daterange and trying to insert documents. I am getting the following error:

Exception while simulating the effect of invoking '/carpool_events/insert'

This is my loop with the insert. I have tested the loop by just writing to console.log instead of inserting and the loop works fine

    'click button.save-addEventDialogue': function(e, tmpl) {

          var start = Session.get("showAddEventDialogue_dateRangeStart");
          var end = Session.get("showAddEventDialogue_dateRangeEnd");
          var dateRange = moment().range(moment(start),moment(end));
          var dateLoopIncrement = moment().range(moment(start),moment(start).add('days',1));

          console.log(dateRange);
          console.log(dateLoopIncrement);

          // Loop through the date range
          dateRange.by(dateLoopIncrement, function(moment) {
            // Do something with `moment`
            var dateToSave = dateRange.start;  

        // Insert the record
            Carpool_Events.insert({
                       owner: Meteor.user().profile.name,
                       owner_id: Meteor.userId(),
                       original_owner: Meteor.user().profile.name,
                       original_owner_id: Meteor.userId(),
                       declined: 0,
                                  date: dateToSave.toDate()
                      });
            dateToSave.add('days',1);
         });            

         // Clear the Session
         Session.set("showAddEventDialogue_dateRangeStart","");
         Session.set("showAddEventDialogue_dateRangeEnd","");

         // Close the dialogue
         Session.set("showAddEventDialogue", false);
       } 

What is the right way to do this? Thanks.

Answer 1

The error message Sorting not supported on Javascript code is a result of inserting a JavaScript function (!) into a collection — for example, by doing something like Carpool_Events.insert({x: function () { ... }}); JavaScript functions should not normally go into collections.

Somewhere in your code there is probably a typo where you are not calling a function (for example, writing Meteor.userId on the client instead of Meteor.userId().) My guess would be that in the process of making your code run on the server, you coincidentally fixed or avoided this.

I wasn’t able to visually find the problem in your code — if I’m wrong, to make more progress it would be helpful to have a reproduction.
