ember.js - Ember js属于关系

Question

我有两个模型 employee 和 empdetails

//employee model
import DS from 'ember-data';
export default DS.Model.extend({
    empId : DS.attr(),
    password : DS.attr(),
    email : DS.attr(),
    empdetails : DS.belongsTo("empdetails") 
});

//empdetails model
import DS from 'ember-data';    
export default DS.Model.extend({
    firstName : DS.attr(),
    lastName : DS.attr(),
    dateOfJoining: DS.attr(),
    employee : DS.belongsTo("employee")
});

我使用 RESTAdapter 进行 REST 调用。

//serializer
import DS from 'ember-data';
export default DS.JSONSerializer.extend({
});

当我尝试为员工发出获取请求时，出现以下错误

Please check your serializer and make sure it is serializing the relationship payload into a JSON API format. Error: Assertion Failed: Encountered a relationship identifier without a type for the belongsTo relationship 'empdetails' on , expected a json-api identifier with type 'empdetails' but found '{"id":"1","firstName":"xxx"}

我从我的后端得到下面的 JSON

[
  {
    "id": 1,
    "email": "xyz@gmail.com",
    "password": "12345678",
    "empdetails": {
      "id": 1,
      "firstName": "xxx",
      "lastName": "yyy",
      "dateOfJoining": "22-10-2018"
    }
  }
]

谁能指导我改正错误

尝试按如下方式更新您的员工序列化程序:

import DS from 'ember-data';

export default DS.JSONSerializer.extend(DS.EmbeddedRecordsMixin, {
    attrs: {
        empdetails: {
            serialize: 'records',
            deserialize: 'records'
        }
}});
