格式返回当前用户.
使用createRecord直接在模型上设置返回的JSON属性.例如,is_private变为user.is_private,而不是user.get(‘isPrivate’)?
如何加载用户模型以便正确设置属性并且我不必使用id重新获取它?
:
Loading Data
Previously, some features of the store, such as load()
, assumed a
single adapter.
If you want to load data from your backend without the application
asking for it (for example, through a WebSockets stream), use this
API:
store.adapterForType(App.Person).load(store, App.Person, payload);
This API will also handle sideloaded and embedded data. We plan to add
a more convenient version of this API in the future.
但不幸的是,尽管文档声称,它并不处理侧载数据.我个人使用类似下面的内容,它基于如何实现find(ID):
var id = json["person"]["id"]; var store = DS.get("defaultStore"); var adapter = store.adapterForType(App.Person); adapter.didFindRecord(store, App.Person, json, id); var person = App.Person.find(id);
请注意,此代码假定JSON的格式与find(ID)期望从服务器接收的格式相同,如 documented in the RESTAdapter guide :
{ person: { id: 1, is_private: false, projects: [3] }, projects: [ { id: 3, name: "FooReader" } ] }
这将应用您使用keyForAttributeName配置的任何转换(例如将is_private映射到isPrivate),它将处理侧载记录.我不确定这是不是最好的做法,但效果很好.
