在 Ember.js 中从belongsTo 关联中查找记录 [英] Find record from belongsTo association in Ember.js

问题描述

如何从 Ember 模型中获取关联记录?或者:如何从Promise对象中获取记录?

How can I get the associated record from an Ember model? Or: how to get the record from the Promise Object?

客户模型

Docket.Customer = DS.Model.extend({
  name:        DS.attr('string'),
  initial:     DS.attr('string'),
  description: DS.attr('string'),
  number:      DS.attr('string'),
  archived:    DS.attr('boolean'),
  projects:    DS.hasMany('project',{ async: true })
});

项目模型

Docket.Project = DS.Model.extend({
  name:        DS.attr('string'),
  description: DS.attr('string'),
  number:      DS.attr('string'),
  archived:    DS.attr('boolean'),
  customer:    DS.belongsTo('customer', { async: true })
});

查找方法

var project = this.store.find('project', id).then(function(data) {
  console.log(data.get('customer').toString());
});

控制台输出

<DS.PromiseObject:ember654> 

JSON 响应

{"projects":[
  {
    "id":1,
    "name":"test",
    "number":"a310",
    "description":null,
    "archived":false,
    "customer_id":22
  }
]};

推荐答案

用另一个然后就搞定 :)

use another then on the get :)

var project = this.store.find('project', id).then(function(data) {
  data.get('customer').then(function(c){
    console.log(c);
  }
});
