使用Ember Data存储从另一个命名空间注册模型 [英] Registering models from another namespace with the Ember Data store

问题描述

我正在使用一个共享库，该库具有调用应用程序使用的内部Ember数据模型。但是，库中的 DS.Model 对象不能找到他们进入调用应用程序的存储的方式。

library.js

  DS .SharedLibrary.User = DS.Model.extend（{}）; 
 DS.SharedLibrary.BaseModel = DS.Model.extend（{
 createdBy：DS.belongsTo（'DS.SharedLibrary.User'）
}）; 
  

app.js

  App.MyModel = DS.SharedLibrary.BaseModel.extend（{
 customField：DS.attr（）
}）; 
  

但是，当适配器解决 createdBy 关系：

 错误：没有找到DS.SharedLibrary.BaseModel的模型
  

如何通知我存储在另一个命名空间中的对象？

解决方案

您可以通过在库中设置 Application.initializer 来注册您的自定义模型：

  Ember.Application.initializer（{
 name：'myLibrary-models'，
 
 initialize：函数（容器，应用程序）{
 //每个模型的这些调用之一，您需要注册
 application.register（'model：DS.SharedLibrary.User'，DS.SharedLibrary.User）; 
} 
}）; 
  

然后，您的应用程序的模型可以像其他任何参考一样：

  App.MyModel = DS.Model.extend（{createdBy：DS.belongsTo（'DS.SharedLibrary.User'）}）; 
  

I'm working on a shared library that has internal Ember Data Models that are used by the calling application. However, those DS.Model objects from the library don't find their way into the store for the calling application.

library.js

DS.SharedLibrary.User = DS.Model.extend({});
DS.SharedLibrary.BaseModel = DS.Model.extend({
    createdBy: DS.belongsTo('DS.SharedLibrary.User')
});

app.js

App.MyModel = DS.SharedLibrary.BaseModel.extend({
    customField: DS.attr()
});

However, when the adapter goes to resolve the createdBy relationship:

Error: No model was found for 'DS.SharedLibrary.BaseModel'

How can I inform my store of objects that exist in another namespace?

解决方案

You can register your custom models by setting up an Application.initializer inside the library:

Ember.Application.initializer({
    name: 'myLibrary-models',

    initialize: function(container, application) {
        //one of these calls for each model you need to register
        application.register('model:DS.SharedLibrary.User', DS.SharedLibrary.User);
    }
});

Then your application's models can reference them like any other:

App.MyModel = DS.Model.extend({ createdBy: DS.belongsTo('DS.SharedLibrary.User') });
