使用Ember.js为每个模型添加额外的url参数 [英] Add extra url params per model with Ember.js

问题描述

我有两个模型：

App.Providers = DS.Model.extend({    
    name: DS.attr('string'),
    description: DS.attr('string'),
    logo: DS.attr('string'),
    products: DS.hasMany('App.Products')
});

App.Products = DS.Model.extend({    
    name: DS.attr('string'),
    description: DS.attr('string')
    provider: DS.belongsTo('App.Providers'), 
});

他们都使用相同的适配器。但是，对于产品模型，我想在url中附加一个额外的URL参数（api键）。如何扩展适配器（或串行器？）来实现？

They are both using the same Adapter. However, for the Products model I want to append an extra url param (the api key) to the url. How can I extend the adapter (or the serializer?) to implement this?

所以只是给我一个例子，当我想为提供者做一个GET：

So just to give you an example when I want to do a GET for providers:

http://example.com/ap1/v1/providers/

和对于产品：

http://example.com/ap1/v1/products/?api_key=1234

我知道我可以添加这个，当我做 App.Products.find（{api_key = 1234} ）但是当我这样做时会出现问题：

I know I can add this when I do App.Products.find({api_key=1234}) but the problem occurs when I do:

var providers = App.Providers.find(1);
providers.get('products');

编辑：
我试图覆盖适配器中的buildURL方法，但不是很方便，因为我只想为某些型号追加api_key参数。

I have tried to override the buildURL method in the adapter but it's not very convenient since I want to append the api_key param only for certain models.

推荐答案

您应该创建一个覆盖buildURL方法的第二个适配器。然后将该适配器注册给应该使用api密钥的任何类型。

You should create a second adapter which overrides the buildURL method. Then register that adapter for any types that should be using an api key.

apiAdapter = originalAdapter.extend({
  buildURL: ....
}));

Store.registerAdapter(App.Providers, apiAdatper);

有关每种类型适配器的详细信息，请参阅此文章：如何使用DS.Store.registerAdapter
