title: Backbone localstorage - A "url" must be specified (without view)
body: <p>I know there are more similar questions like this, but I really couldn't find the answer to my problem..</p>
  
  <p>Here is my jsfiddle: <a href="http://jsfiddle.net/ktyghnL1/3/" rel="nofollow">http://jsfiddle.net/ktyghnL1/3/</a></p>
  
  <p>Code:</p>
  
  <pre><code>var Todo = Backbone.Model.extend({
  });
  
  var Todos = Backbone.Collection.extend({
      model: Todo,
      localStorage: new Backbone.LocalStorage('todos-backbone'),
      comparator: 'order'
  });
  
  todos = new Todos();
  </code></pre>
  
  <p>I am only using models and collections for my angularjs app.</p>
  
  <p>When I try to create an new todo, it fails.</p>
