title: How to show data from mongoDB with ObjectID
body: <p>i have an "back end" application which write in MongoDb (in database i have _id: with ObjectId("13f6ea...002")) i use meteor app to show information. Everything was good i displays list of information with {{#each}}. But when i wanted show one element with '_Id' nothing works.</p>
  
  <p>I read <a href="https://stackoverflow.com/questions/21317621/understand-new-mongo-id-and-use-it-with-iron-router/23417420#23417420">this issue</a> and adapt my code to get right root, But i can't display anything on the page. I tried to write Template helpers but it didn't helped</p>
  
  <p>Db record:</p>
  
  <pre><code>  {
   _id: ObjectId("13f6ea...002"),
   url: "foo",
   title: "bar",
   published: "2014-08-22 03:26:21 UTC",
   image: "foo.jpg",
   summary: "foo ",
   categories: [
     "F",
     "B"
    ],
    ...
    }
  </code></pre>
  
  <p>Route:</p>
  
  <pre><code>this.route('news', {
  path: '/news/:_id',
  template: 'news',
  waitOn: function () { 
    var id = this._id; 
    Meteor.subscribe('news', id);
  },
  data: function() {
    var id = this.params._id;
    return News.findOne({ _id: Meteor.Collection.ObjectID(this.params._id)});
  },
   action : function () {this.render();},
  });
  </code></pre>
  
  <p>Publish </p>
  
  <pre><code>Meteor.publish('news', function(id) {
    return News.find({_id: id}); 
  });
  </code></pre>
  
  <p>Template which redirect to unique post </p>
  
  <pre><code>&lt;h4&gt;&lt;a href="{{pathFor 'news' _id=this._id.toHexString}}"&gt;{{title}}&lt;/a&gt;&lt;/h4&gt;
  </code></pre>
  
  <p>And template is just {{news}}</p>
  
  <p>How can i fix this?</p>
  
  <hr>
  
  <p><strong>UPDATE</strong></p>
  
  <p>My solutions to fix that:</p>
  
  <p>router.js</p>
  
  <pre><code>waitOn: function () {
    var id = this._id;
    Meteor.subscribe('News', id);
  },
  data: function() {
    return News.findOne(new Meteor.Collection.ObjectID(this.params._id));
  },
  </code></pre>
  
  <p>and in template </p>
  
  <p><code>&lt;a href="news/{{_id._str}}"&gt;</code></p>
