title: AngularJS default value for ng-model
body: <p>Is it possible to make ng-models get default values, like <code>''</code>?</p>
  
  <p>I have a form on which I have used jQuery's <code>serialize</code> function, and whenever a a value is not present, it will still include it in the serialized data, E.g. <code>{name: '', age: ''}</code>.</p>
  
  <p>However, when I use try using posting it by using Angular's <code>$http</code> and getting the model from <code>$scope</code>, it appears as <code>undefined</code> when it is empty.</p>
