EmberJS中的RESTAdapter

Question

我是EmberJs的新手，我在Ember的Adapter中不清楚，我只是在App.Js中尝试了ember适配器，却遇到了这样的错误（断言失败：您尝试将adapterproperty 设置为的实例DS.Adapter，在这里应该是名字或工厂）。我在App.js中的余烬代码是：

//Store
App.Adapter =  DS.RESTAdapter.extend();
App.Store = DS.Store.extend({
    revision: 12,
    adapter: App.Adapter.create()
});
//Models
App.Product = DS.Model.extend({
    name: DS.attr('string'),
    description: DS.attr('string'),
    price: DS.attr('number')
});

// Products Route
 App.ProductsRoute = Ember.Route.extend({
  model: (function() {
      return this.store.find('Product');
  })
});
return App;

我认为您误解了设置和配置适配器的方式。

//
// Application-wide adapter, everything will use this unless you override it
//

App.ApplicationAdapter =  DS.RESTAdapter.extend({
  host: 'https://api.example.com'
});

//
// Product model, will use ApplicationAdapter
// 

App.Product = DS.Model.extend({
  name        : DS.attr('string'),
  description : DS.attr('string'),
  price       : DS.attr('number')
});

//
// Invoice model, will use fixtures, so specify a different adapter 
// 

App.InvoiceAdapter =  DS.FixtureAdapter.extend({ /* options */ });

App.Invoice = DS.Model.extend({
  name   : DS.attr('string'),
  amount : DS.attr('number')
});

//    
// Routes, these should work as expected
//

App.ProductRoute = Ember.Route.extend({
  model: function(params) {
    return this.store.find('product', params.id);
  }
});

App.ProductsRoute = Ember.Route.extend({
  model: function() {
    return this.store.find('product');
  }
});

App.InvoicesRoute = Ember.Route.extend({
  model: function() {
    return this.store.find('invoice');
  }
});

return App;

Ember会根据其名称知道要使用的型号/路线/等- 有关详细信息，请参见http://emberjs.com/guides/concepts/naming-conventions/。
