ember.js - 处理路线时出错，工厂未定义

Question

我尝试通过 RESTAdapter 获取数据(按照教程)，但收到一个我不明白的错误。

"Error while processing route: players.index" "factory is undefined" "Store<.modelFor@http://localhost:4200/assets/vendor.js:74981:1

有人知道我错过了什么吗？我需要安装附加组件吗？

routes/players/index.js

import Ember from 'ember';

export default Ember.Route.extend({
  model: function() {
    return this.store.find('player');
  }
});

models/player.js

import DS from 'ember-data';

export default DS.Model.extend({
  finalScore: DS.attr('number'),
  name: DS.attr('string'),
  heightFormatted: DS.attr('string'),
  heightCm: DS.attr('number'),
  weightLb: DS.attr('number'),
  weightKg: DS.attr('string'),
  birthplace: DS.attr('string'),
  birthdate: DS.attr('string'),
  neoId: DS.attr('number'),
  position: DS.attr('string'),
  number: DS.attr('string'),
  faults: DS.attr('number'),
  stats: DS.belongsTo('stat')
});

models/stat.js

import DS from 'ember-data';

export default DS.Model.extend({
  points: DS.attr('number'),
  assits: DS.attr('number'),
  defr: DS.attr('number'),
  ofr: DS.attr('number'),
  steals: DS.attr('number'),
  blocks: DS.attr('number'),
  turnovers: DS.attr('number'),
  fta: DS.attr('number'),
  ftm: DS.attr('number'),
  fga: DS.attr('number'),
  fgm: DS.attr('number'),
  lsa: DS.attr('number'),
  lsm: DS.attr('number'),
  minutes: DS.attr('number'),
  isStarter: DS.attr('boolean'),
  gamesPlayed: DS.attr('number'),

  player: DS.belongsTo('player')
});

适配器/application.js

import DS from 'ember-data';

export default DS.RESTAdapter.extend({
  host: 'http://localhost:3000',
  namespace: 'api'
});

我无法重现您的确切错误，但根据您共享的内容，我能够通过进行这些更改来使其正常工作。如果您的代码有不同之处请发表评论，我会查看。

序列化器/application.js

由于您使用的是自定义主键(neo_id 而不是 id)，因此您可以在此处进行更改，并指示 stats 记录嵌入在 players 中数据:

export default DS.RESTSerializer.extend(DS.EmbeddedRecordsMixin, {
  attrs : {
    stats: { embedded: 'always' }
  },
  primaryKey : 'neo_id'
});
