I would like to use both adapters, depending on the route. Currently I have the following store:
if (window.USE_FIXTURES) { var my_adapter = \'DS.FixtureAdap
@intuitivepixel's answer no longer works in current day Ember (v1.0+); as registerAdapter no longer exists in the API.
Nowadays you can just declare an Adapter for each model where you want to override the adapter choice:
App.LegacyModel = DS.Model.extend({
name: DS.attr('string'),
});
App.LegacyAdapter = DS.FixtureAdapter;
