Non-persistent attributes in EmberJS

Question

Does anyone know of a way to specify for an Ember model an attribute which is not persisted?

Basically, we\'re loading some metadata related to each model

Answer 1

The other answers to this question work with Ember data versions up to 0.13, and no longer work. For Ember data 1.0 beta 3 you can do:

App.ApplicationSerializer = DS.RESTSerializer.extend({
  serializeAttribute: function(record, json, key, attribute) {
    if (attribute.options.transient) {
      return;
    }
    return this._super(record, json, key, attribute);
  }
});

Now you can use transient attributes:

App.User = DS.Model.extend({
  name: DS.attr('string', {transient: true})
});

These attributes won't be sent to the server when saving records.
