title: Backbone fetch() throws an Uncaught TypeError: Cannot read property 'ajax' of undefined
body: <p>I am integrating BackBone on a new project. While I am somewhat familiar with BackBone, this will be my first attempt at creating a new project with it.</p>
  
  <p>I setup a model and view, but am getting a console error that doesn't return any helfpul results on StackOverflow or Google. I'm hoping someone here can spot where I've gone wrong.</p>
  
  <p>Here's the error, which occurs when I call <code>thing.fetch()</code></p>
  
  <pre><code>Uncaught TypeError: Cannot read property 'ajax' of undefined 
  </code></pre>
  
  <p>And here's my CoffeeScript code:</p>
  
  <pre><code>Thing = Backbone.Model.extend
      name: 'thing'
      url: -&gt;
          "/things/#{@id}"
  
  ThingView = Backbone.Model.extend
      el: "#thing"
      render: -&gt;
          console.log 'render', @$el
  
  thing = new Thing(id: 1)
  thing.fetch()
  
  thingView = new ThingView()(model: Thing)
  thingView.render()
  </code></pre>
