使用JSONAPI访问hasMany/belongsTo关系数据

Question

请问您能帮我吗？

我有一个模型Channel，模型Feature，模型ChannelApplication和模型ApplicationFeature。我将它们定义是这样的：

我的模型channel.js：

import Model from 'ember-data/model'; 
import attr from 'ember-data/attr'; 
import { hasMany } from 'ember-data/relationships'; 

export default Model.extend({ 
    name: attr('string'), 
    key: attr('string'), 
    multiplePages: attr('boolean'), 
    features: hasMany('feature', { async: true }) 
}); 

我的模型feature.js：

import Model from 'ember-data/model'; 
import attr from 'ember-data/attr'; 
import { hasMany } from 'ember-data/relationships'; 

export default Model.extend({ 
    name: attr('string'), 
    key: attr('string'), 
    applicationFeatures: hasMany('application-feature', { async: true }), 
    channels: hasMany('channel', { async: true }) 
}); 

我的模型channel-application.js：

import Model from 'ember-data/model'; 
import attr from 'ember-data/attr'; 
import { belongsTo, hasMany } from 'ember-data/relationships'; 

export default Model.extend({ 
    name: attr('string'), 
    clientId: attr('string'), 
    channel: belongsTo('channel'), 
    applicationFeatures: hasMany('application-feature', { async: true }) 
}); 

我的模型application-feature.js

import Model from 'ember-data/model'; 
import attr from 'ember-data/attr'; 
import { belongsTo } from 'ember-data/relationships'; 

export default Model.extend({ 
    scope: attr('string'), 
    connectType: attr('string'), 
    channelApplication: belongsTo('channel-application', { async: true }), 
    feature: belongsTo('feature', { async: true }) 
}); 

我正在使用JSONAPI。而在我的路线我这样做：

model() { 
    return Ember.RSVP.hash({ 
     profiles: this.store.findAll('profile'), 
     channels: this.store.findAll('channel'), 
     channelApplications: this.store.query('channel-application', { filter: { feature: 'inbox'} }) 
    }) 
} 

所以，在我的模板，我需要让我的ChannelApplications并为每一个我需要知道Channel与此相关ChannelApplications，知道每个ApplicationFeature。

{{#each channelApplications as |channelApplication|}} 
    {{channelApplication.id}} 

    // I think in something like this, but this doesn't work of course 
    {{#each channelApplication.channels as |channel|}} 
     <span>{{channel.id}}</span> 
     <span>{{channel.name}}</span> 
     {{#each channelApplication.applicationFeatures as |applicationFeature|}} 
      <span>{{applicationFeature.id}}</span> 
      <span>{{applicationFeature.name}}</span> 
     {{/each}} 
    {{/each}} 

{{/each}} 

channelApplication.applicationFeatures和channelApplication.channels没有返回。

当我打印{{channelApplication.applicationFeatures.length}}它返回0

当我打印{{channelApplication.applicationFeatures}}它打印channelApplications: this.store.query('channel-application', { filter: { feature: 'inbox'} })一个<DS.PromiseManyArray>

JSONAPI回报：任何事情

     } 
    ] 
} 

所以，有人知道我在做错了，拜托？

您的回复不正确JSONAPI。也不清楚：channel-application有一个或多个channel？

因为channel: belongsTo('channel'),意味着它有一个channel，但你不应该像{{#each channelApplication.channels as |channel|}}一样循环它们。

如果你有一个channel你不能返回"channel-id":1,作为一个属性，但应该返回一个关系：

channel: { 
    data: { 
    type: 'channel', 
    id: '1' 
    } 
}
