Iron Router routing entry data retrieval function run twice

I'm new to Meteor (and full stack JS development for that matter) and experimenting a bit trying to convert an app I currently have running on Google App Engine in Django/Python.

I have the following route entry using Iron Router:

this.route("editFacility", {
  path: "/facilities/:_id/edit",
  template: "editFacility",
  data: function() {
    return Facilities.findOne({ _id: this.params._id });
  }
});

... and the following template (using autoform's quickform):

<template name="editFacility">
  <h2>Edit facility "{{description}}"</h2>
  <div class="row">
    <div class="col-md-12">
      {{> quickForm
        collection="Facilities"
        omitFields="createdAt, updatedAt"
        doc=this
        id="updateFacilityForm"
        type="update"
        template="bootstrap3-horizontal"
        label-class="col-sm-2"
        input-col-class="col-sm-6"}}
    </div>
  </div>
</template>

The route gets triggered by:

{{#linkTo route='editFacility' _id=this._id class="btn btn-default btn-xs"}}Edit{{/linkTo}}

Initially it looked like the form wasn't filled with data, but putting a debugger statement in the route's data: function revealed that this function is actually ran twice. The first time finding the document and correctly filling the form, immediately followed by a second time and failing the find thus clearing the form. The stack doesn't reveal any particulars and looks identical for both runs:

I googled the issue and found some references but none with a clear solution. I've updated meteor and all my packages to the latest & greatest but this issue persists.

So my question, what causes meteor / Iron Router to execute this route entry twice?

Solution

  • Seems like you are missing the package autopublish from your package list. It's responsible for publishing every data available in the server. Otherwise you need to write a publication and then subscribe it back in the client.
