title: How to call fetch method of Backbone Collection passing Id
body: <p>I want to fire <code>fetch</code> method on Backbone Collection which would pass an Id parameter similar to what happens in <code>Model.fetch(id)</code></p>
  
  <p>E.g. </p>
  
  <pre><code>var someFoo= new Foo({id: '1234'});// Where Foo is a Backbone Model
  someFoo.fetch();
  </code></pre>
  
  <p>My Backbone collection:-</p>
  
  <pre><code>var tasks = backbone.Collection.extend({
      model: taskModel,
      url: '/MyController/GetTasks',
      initialize: function () {
          return this;
      }
  });
  </code></pre>
  
  <p>In my View when I try to fetch data:-</p>
  
  <pre><code>var _dummyId = 10; //
  
  // Tried approach 1 &amp;&amp; It calls an api without any `id` parameter, so I get 500 (Internal Server Error).
  this.collection.fetch(_dummyId); 
  
  
  // Tried approach 2 &amp;&amp; which fires API call passing Id, but just after that 
  // I am getting error as below:- Uncaught TypeError: object is not a function
  this.collection.fetch({
      data: {
          id: _dummyId
      }
  });
  </code></pre>
  
  <p>Found it very late : To cut short the above story I want something like <a href="https://stackoverflow.com/questions/6262444/get-collection-id-in-backbone-without-loading-the-entire-collection"><strong>Get /collection/id in backbone</strong></a>. </p>
