如何使用DS.Store.registerAdapter

Question

我尝试使用ember-data的"每种类型的适配器"功能.不确定我做错了什么,或者它是否是ember-data中的错误.基本上我认为它会像这样工作:

Person = DS.Model.extend({
  name: DS.attr('string')
});
var personAdapter = DS.Adapter.create();
DS.Store.registerAdapter(Person, personAdapter );

商店总是使用默认适配器而不是注册的'每类型适配器'我写了一个测试用例来表明我的意思:

var get = Ember.get, set = Ember.set;
var Person, store, adapter, personAdapter;

module("DS.Store and DS.Adapter 'adapter per type' integration test", {
  setup: function() {
    Person = DS.Model.extend({
      name: DS.attr('string')
  });

  adapter = DS.Adapter.create();
  personAdapter = DS.Adapter.create();

  DS.Store.registerAdapter(Person, personAdapter);
    store = DS.Store.create({ adapter: adapter });
  },

  teardown: function() {
    adapter.destroy();
    store.destroy();
  }
});


test("test function on the per type adapter", function() {

  adapter.find = function(store, type, id) {
    ok(false, "should call find on the registered 'per type adapter' not on the default one");
  };

  personAdapter.find = function(store, type, id) {
    store.load(Person, {
      'id': 1,
      'name': "My Name"
    });
  };

  var person = store.find(Person, 1);
  equal(person.get('name'), "My Name");
});

在调试时我注意到"DS.Mappable._reifyMapping"混合显式检查DS.Store并在"this"是DS.Store时停止.

这应该工作.

var get = Ember.get, set = Ember.set;
var Person, StoreClass, store, adapter, personAdapter;

module("DS.Store and DS.Adapter 'adapter per type' integration test", {
  setup: function() {
    Person = DS.Model.extend({
      name: DS.attr('string')
    });

    adapter = DS.Adapter.create();
    personAdapter = DS.Adapter.create();

    StoreClass = DS.Store;
    StoreClass.registerAdapter(Person, personAdapter);
    store = StoreClass.create({ adapter: adapter });
  },

  teardown: function() {
    adapter.destroy();
    store.destroy();
  }
});
