iron router - Meteor client side collection needs to have all data populated before anything else -

I'm trying to use the client side store as a site configuration system. I incorporate the documents representing my various pages, and using the iron-router and navigation tabs, they use all to determine which pages they are and their Which templates are presented by each page a {{& gt; ContentTemplate}} The Insertion Assistant has to load this relevant template.

It all works great, when all the data is loaded. When I restart the app on some pages, the data is not loaded yet, and I get an exception from the Dipes Recomputing Function: Error: Expected faucet or template was found in exchange for the included function: Undefined < / code> error.

Here is my javascript:

  Storyrere = [{Category: 'Teaching', Content Template: 'teachingHome', Title : 'Teaching Home'}, ...]; Stories = New Meteor. Compile (empty); Story More Year (function (story, index) {story._id = index + ''; storyjinst (story);}); // in main.js Template.teachingPost.contentTemplate = function () {console.log (this); Console.log (this.contentTemplate); Return template [this.contentTemplate]; }; // in router.js this.route ('teaching', {layoutTemplate: 'teachingPost', data: function () {back stories.fundon ({content title: 'teaching home', category: 'teaching'})}} }); Log on twice to   
 console  contentTemplate  assistant, for the first time in this form:  
  object {} main JS? 1f560c50f23d9012c6b6dd54469bb32b99aa4285: 45 undefined main.js? 1f560c50f23d9012c6b6dd54469bb32b99aa4285: 46   
 and second time like this:  
  object {category: "teaching", contentTemplate: "teaching home", title: "Teaching Home "} main. Js? 1f560c50f23d9012c6b6dd54469bb32b99aa4285: 45th Home of Education: JS? 1f560c50f23d9012c6b6dd54469bb32b99aa4285: 46   
 So the router is just trying to load this data very quickly.  
 I have put the process of loading code into different files in my code, including  lib , and even so That it is  Meteor.startup , but it is always the same result.  
 Normal  iron-router   wait  /  subscription  pattern does not really apply here because it is a client side The memory which is w ith  null , which has no server representation, I do not want to   for the representation of the server, because it is the static content that no need to go to my server is not.  
 How can I ensure that this information has already been released?   
 
 
 unchecked, but copy:  
 
 return a subscription handle, Or with any  ready  to the  ready  method, any task will add the handle to a waiting list.   
 In addition to this, it is better to use  find  with  data ,  findOne  As  Find  the collection is empty when an empty cursor will return, as opposed to  findOne  return  undefined . Then try it:   router.js this.route ('teaching', {layoutTemplate: 'teachingPost', data: function () {return stories. Search ({contentTemplate: 'teaching home, category:' Learning}}}, wait: function () handle {var handle = {} handle.read = function () {if (Stories.find). Count ()! == 0) return true; and false return;} Return handle;}});   
 and adjust your  Template.teachingPost.contentTemplate  function to work with the cursor instead of the object.
