title: emberjs record.save() throwing TypeError: Cannot read property 'hasOwnProperty' of null
body: <p>am having an issue where my emberjs on record.save() is throwing</p>
  
  <p>"TypeError: Cannot read property 'hasOwnProperty' of null"</p>
  
  <p>here is my code</p>
  
  <pre><code>App.Signup = DS.Model.extend({
      email: DS.attr('string'),
      password: DS.attr('string')
  });
  
  App.SignupController = Ember.ArrayController.extend({
  actions: {
      cliky: function() {
          var sElement = this.store.createRecord('signup', {
              email: "test",
              password: "test1",
          }).save();
      },
  }
  });
  </code></pre>
  
  <p>fixed the bottom errors with the fixed response on the server side ( i hardcoded for testing). but the information comming from Emberjs is null!</p>
  
  <p>I am using the Django rest framework and when i do print request.DATA it is 'none'...</p>
  
  <p>So am i printing something wrong from django?</p>
