title: Ember.js: how to save a model
body: <p>From the ember docs its clear you should be able to save a dirty model</p>
  
  <pre><code>var m = App.MyModel.find(10) ;
  ...
  m.set("firstName", "John") ;
  m.get("isDirty") ; // --&gt; true
  </code></pre>
  
  <p>Now, I don't know how to save, things like</p>
  
  <pre><code>m.save() ;
  App.MyModel.save(m) ;
  //etc
  </code></pre>
