javascript - 尝试在 ember.js 中 self 引用模型时出错

Question

我正在尝试在模型中创建自引用属性，但出现以下错误:

Error while processing route: index No model was found for 'menu' Error

这是我的模型(menus.js):

import DS from 'ember-data';

export default DS.Model.extend({    
  title: DS.attr('string'),
  link: DS.attr('string'),
  isActive: DS.attr('boolean'),
  children: DS.hasMany('menus', { inverse: null }),
});

我正在尝试从 Web API 返回一个列表。这是我的 API JSON 返回:

[
  {
    "id": 1,
    "title": "Test",
    "link": "index",
    "isActive": false,
    "children": [
      {
        "id": 4,
        "title": "Test 2",
        "link": "index",
        "isActive": false
      }
    ]
  },
  {
    "id": 2,
    "title": "Test 2",
    "link": "index",
    "isActive": false,
    "children": [
      {
        "id": 5,
        "title": "Test 4 ",
        "link": "index",
        "isActive": false
      }
    ]
  },
  {
    "id": 3,
    "title": "Test 5",
    "link": "index",
    "isActive": false,
    "children": [
      {
        "id": 6,
        "title": "Test 6",
        "link": "index",
        "isActive": false
      },
      {
        "id": 7,
        "title": "Test 7",
        "link": "index",
        "isActive": false
      }
    ]
  }
]

Answer 1

您应该以单数形式调用您的模型。因此，将 model/menus.js 重命名为 model/menu.js 和 DS.hasMany('menus', { inverse: null }),使用 DS.hasMany('menu', { inverse: null }),。
