Class DS.Transform

Defined in: packages/ember-data/lib/transforms/base.js:1
Module: ember-data

The DS.Transform class is used to serialize and deserialize model attributes when they are saved or loaded from an adapter. Subclassing DS.Transform is useful for creating custom attributes. All subclasses of DS.Transform must implement a serialize and a deserialize method.

// Converts centigrade in the JSON to fahrenheit in the app
export default DS.Transform.extend({
  deserialize: function(serialized) {
    return (serialized *  1.8) + 32;
  },
  serialize: function(deserialized) {
    return (deserialized - 32) / 1.8;
  }
});
