获取错误：您需要将模型名称传递给商店的modelFor方法 [英] Getting error: You need to pass a model name to the store's modelFor method

问题描述

使用Ember 2.6.0

Using Ember 2.6.0

确定以下路线：

Router.map(function() {
  this.route('brands');
  this.route('brand', {path: '/brands/:brand_id'});
});

品牌的型号是： p>

The model for brand is:

export default Model.extend({
  name: attr('string'),
  description: attr('string'),
  dateCreated: attr('date'),
  lastUpdated: attr('date'),
  regions: hasMany('region')
});

而区域的模型是： / p>

And the model for region is:

export default Model.extend({
  name: attr('string'),
  dateCreated: attr('date'),
  lastUpdated: attr('date'),
  brand: belongsTo('brand')
});

现在，尝试访问 /品牌我在路线上这样做：

Now, when trying to access /brands I am doing this in the route:

export default Ember.Route.extend({
  model() {
    return this.store.findAll('brand');
  }
});

我收到以下错误：

您需要将模型名称传递给商店的modelFor方法

You need to pass a model name to the store's modelFor method

code>品牌路线和区域关系。品牌是父母，所以我不知道为什么这不工作。

This worked prior to adding the brand route and region relationships. Brand is the parent, so I'm not sure why this isn't working.

更新：

从品牌中删除​​区域：hasMany（'region'）允许事情再次工作。不知道为什么它不能与定义的关系使用。

Removing regions: hasMany('region') from the brand model allows things to work again. Not sure why it isn't working with the defined relationship.

推荐答案

所以原来我必须为每个对象创建序列化。对于品牌我有：

So it turns out I had to create serializers for each object. For brand I have:

import RESTSerializer from 'ember-data/serializers/rest';
import DS from 'ember-data';

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

而对于区域我有： p>

And for region I have:

import RESTSerializer from 'ember-data/serializers/rest';

export default RESTSerializer.extend({
});

从技术上讲，它没有区域序列化程序，但是我收到一个警告，即ember找不到$ 区域内的c $ c>区域。我可以向ember提交一张机票，建议不要创建一个空的 RESTSerializer ，以避免此警告。

Technically, it works without the region serializer but I get a warning that ember couldn't find regions inside the region model. I may submit a ticket to ember to suggest not having to create an empty RESTSerializer just to avoid this warning.
