Question

我正在使用的API端点返回其中包含多个嵌套关系的数据，我在normalizeResponse()中使用DS.JSONAPISerializer将其按到完全是JSON-API的内容兼容。

ember检查器显示所有数据都正确放置在各自的容器中。顶级模型与其hasMany子级之间的链接确实有效，但嵌套模型之间的链接不起作用。我通过在检查器中导航到嵌套模型的子模型，点击它并观察它的内容来验证这一点。 property is null。

首先，看看我的模型是如何设置的：

// models/search.js
// i am able to browse from the search model to children with success
export default DS.Model.extend({
  articles: DS.hasMany('article'),
});

// models/article.js
// i CANNOT browse from an article down to its digest in ember inspector
export default DS.Model.extend({
  search: DS.belongsTo('search'),
  type: DS.attr(),
  created: DS.attr(),
  updated: DS.attr(),
  digest: DS.belongsTo('digest'),
});

// models/digest.js
export default DS.Model.extend({
  title: DS.attr(),
  desc: DS.attr(),
  date: DS.attr(),
  article: DS.belongsTo('article'),
});

现在，在normalizeResponse内的函数完成后，我的修改后的JSON就行了。从normalizeResponse返回此数据后，＆＃34;摘要＆＃34;父母之间的对象＆＃34;关系＆＃34;对象消失了。我的JSON有问题吗？我已尝试过如此多的排列，但没有成功，我很确定这符合Compound Documents的JSON-API规范。

您的回复表明以下关系模型：

self

所以你必须修复你的回复：

删除// models/search.js export default DS.Model.extend({ articles: DS.hasMany('article'), dignists: DS.hasMany('digest'), }); // models/article.js export default DS.Model.extend({ search: DS.belongsTo('search'), }); // models/digest.js export default DS.Model.extend({ search: DS.belongsTo('search'), });

digest

为每个search

digest

所以你会以这样的结局结束：

article

知道您也可以反过来执行此操作并在{ "data":{ "type":"searches", "id":"17482738723", "attributes":{ }, "relationships":{ "articles":{ "data":[ { "type":"articles", "id":"19988" }, { "type":"articles", "id":"19989" }, ] } } }, "included":[ { "id":"19988", "type":"articles", "attributes":{ "type": "internal", "created":"2016-09-27T00:13:11.000Z", "updated":"2016-09-27T00:13:11.000Z", }, "relationships":{ "digest": { "data": { "type":"digest", "id":"19988_digest" } } } }, { "id":"19988_digest", "type":"digest", "attributes":{ "title":null, "desc":"four five six", }, "relationships":{ "digest":{ "data": { "type":"digest", "id":"19989_digest" } } } }, { "id":"19989", "type":"articles", "attributes":{ "type": "internal", "created":"2016-09-27T00:13:11.000Z", "updated":"2016-09-27T00:13:11.000Z", } }, { "id":"19989_digest", "type":"digest", "attributes":{ "title":"one two three", "desc":null, } }, ] }上指定article。 digest会自动将所有内容保持同步。为了清晰起见，我个人更喜欢指定关系的两个方面。

normalizeResponse无法识别嵌套关系之间的链接
