我有简单的api返回频道,每个频道都包含许多故事。 API为频道返回以下结构:
{
"id": 1,
"name": "The Awesome Channel",
"stories": [
{
"icon": null,
"id": 3,
"pub_date": "2015-08-08T17:32:00.000Z",
"title": "First Cool Story"
},
{
"icon": null,
"id": 4,
"pub_date": "2015-10-20T12:24:00.000Z",
"title": "Another Cool Story"
}
]
}
我定义了以下两个模型,channel.js
:
import DS from 'ember-data';
export default DS.Model.extend({
name: DS.attr('string'),
bgurl: DS.attr('string'),
stories: DS.hasMany('story')
});
和story.js
:
import DS from 'ember-data';
export default DS.Model.extend({
channelId: DS.attr('number'),
title: DS.attr('string'),
pubDate: DS.attr('string'),
icon: DS.attr('string'),
});
我也有这个RESTSerializer来反序列化一个频道:
import DS from 'ember-data';
export default DS.RESTSerializer.extend({
normalizeArrayResponse(store, primaryModelClass, hash, id, requestType) {
var newHash = {
channels: hash
};
return this._super(store, primaryModelClass, newHash, id, requestType);
},
normalizeSingleResponse(store, primaryModelClass, hash, id, requestType) {
// Convert embedded data into a lost of story ids
var stories = hash.stories.map(function(story) {
return story.id;
});
delete hash.stories;
hash.stories = stories;
var newHash = {
channel: hash,
};
return this._super(store, primaryModelClass, newHash, id, requestType);
}
});
上面的代码可以工作,但它会为通道中的每个故事向服务器发出新的请求,但由于数据已包含在响应中,因此不需要这些额外的请求。如果我将故事数据保留为原样,则规范化数据将失败。
有没有办法表明相关模型的数据是否嵌入在响应中?

您是否尝试将故事声明为频道序列化程序中的内容?
export default DS.RESTSerializer.extend(DS.EmbeddedRecordsMixin, {
attrs: {
stories: { embedded: 'always' }
},
normalizeArrayResponse(store, primaryModelClass, hash, id, requestType) {
...
});
