同时使用 DS.FixtureAdapter 和 DS.RESTAdapter [英] Using DS.FixtureAdapter and DS.RESTAdapter at the same time

问题描述

我想使用两个适配器，具体取决于路线.目前我有以下商店:

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.FixtureAdapter'; }
else                     { var my_adapter = SettingsApp.Adapter.create(); }

SettingsApp.Store = DS.Store.extend({
    revision: 12,
    adapter:  my_adapter
});

(SettinsApp.Adapter 是一个 DS.RESTAdapter)

但我想要的是有两家商店.是否可以逐条路由地执行此操作?有人可以提供有关如何为此配置路由器的示例吗?

But what I would like is to have two stores. Is it possible to do this, on a route-by-route basis? Could somebody provide an example on how to configure the router for this?

根据设计，您永远不应该希望在您的应用中有多个商店.但是，每个模型都有一个适配器的可能性存在.

As per design you should never want to have multiple stores in your App. But instead the possibility to have an adapter on a per model basis exists.

这看起来像这样:

DS.Store.registerAdapter('App.LegacyModel', App.MyLegacyAdapter.extend({});

如果您有多个使用相同适配器的模型，您可以这样做:

If you have multiple models that use the same adapter you could do:

DS.Store.registerAdapter(['App.FooModel', 'App.BarModel'], App.MyAdapter.extend({});

然后，商店将在发出请求时使用模型类型对应的适配器.

The store will then use the model type corresponding adapter when making requests.

您仍然可以使用以下语法为商店指定默认适配器:

You can still specify a default adapter for the store by using the this syntax:

App.Store = DS.Store.extend({
  adapter: 'DS.RESTAdapter'
});

如果您尝试加载没有为其类型指定适配器的记录，则此默认适配器将用作后备.

This default adapter will be used as a fallback if you try to load a record that does not have an adapter specified for its type.

是否可以逐条路由地执行此操作?

遵循最佳实践，如果您想使用不同于惯例查找的模型(例如，使用您的路线名称)，您可以执行以下操作:

Following best practices, if you want to use a different model other than the one looked up by convention (e.g. using your route's name) you could do something like:

App.SomeRoute = Ember.Route.extend({
  setupController: function(controller, model) {
    controller.set('model', App.MySpecialModel.find());
  }
});

另外值得一提的是，DS.FixtureAdapter 并没有取代 DS.RESTAdapter 也没有相同的功能集，它只是为了提供简单的模型数据您的应用程序，因此在 DS.FixtureAdapter 的情况下无法在适配器之间切换 &DS.RESTAdapter.当您不关心与后端通信但会将您的数据作为夹具"存储在客户端时，请使用 DS.FixtureAdapter.

Also worth mentioning is that the DS.FixtureAdapter does not replace nor have the same feature set as the DS.RESTAdapter, it's only meant to provide simple mockup data for your app, so switching between adapter's would not work in case of the DS.FixtureAdapter & DS.RESTAdapter. Use DS.FixtureAdapter when you don't yet care to communicate with a backend, but will store your data as "fixtures" in the client.

希望有帮助.
