javascript - Tell ember.js to use different key for its model's "id"

Question

I am stuck in a situation where I shouldn't return id field in the API endpoint. I need to tell ember to use slug field for / instead of id.

I tried DS.RESTAdapter.map('App.Post', id: {key: 'slug'}). While this works perfectly fine for App.Post.find("a-slug-name"), It messes up for App.Post.find() resulting in adding a new model every time it is called. And also assigning id to null.

So how should I do this.

Answer 1

您需要指定应该用作primaryKey适配器中的属性。如果您希望该slug属性用作您的Post模型，请像这样在您的适配器上id定义：primaryKey

DS.RESTAdapter.map('App.Post', {
  primaryKey: 'slug'
});

更新

从 Ember-data 版本1.0.0-beta.7 canary开始，您需要这样做而不是上面的代码段：

App.PostSerializer = DS.JSONSerializer.extend({
  primaryKey: 'slug'
});

我不是 ember 专业人士，但我最近想使用 slug 而不是 ID 并且这样做了，想知道这是否是您所追求的？ https://stackoverflow.com/a/14967337/472852
