Question

应用程序/模型/ index.js

import Model from 'ember-data/model';
import attr from 'ember-data/attr';

export default Model.extend({
  title: attr(),
  owner: attr(),
  city: attr(),
  type: attr(),
  image: attr(),
  bedrooms: attr()    
});

应用程序/模板/ index.hbs

{{#each model as |rental|}}
  <p>Location: {{rental.city}}</p>
  <p>Number of bedrooms: {{rental.bedrooms}}</p>
{{/each}}

我从sinatra返回这个/租赁数据请求

  { data: [{
  id: 1,
  title: 'Grand Old Mansion',
  owner: 'Veruca Salt',
  city: 'San Francisco',
  bedrooms: 15,
  type: 'rental',
  image:     'https://upload.wikimedia.org/wikipedia/commons/c/cb/Crane_estate_(5).jpg'
}, {
  id: 2,
  title: 'Urban Living',
  owner: 'Mike TV',
  city: 'Seattle',
  bedrooms: 1,
  type: 'rental',
  image:     'https://upload.wikimedia.org/wikipedia/commons/0/0e/Alfonso_13_Highrise_T    egucigalpa.jpg'
}, {
  id: 3,
  title: 'Downtown Charm',
  owner: 'Violet Beauregarde',
  city: 'Portland',
  bedrooms: 3,
  type: 'rental',
  image:     'https://upload.wikimedia.org/wikipedia/commons/f/f7/Wheeldon_Apartment_Bu    ilding_-_Portland_Oregon.jpg'
}, {
  id: 4,
  title: 'xDowntown Charm',
  owner: 'Violet Beauregarde',
  city: 'Portland',
  bedrooms: 3,
  type: 'rental',
  image:     'https://upload.wikimedia.org/wikipedia/commons/f/f7/Wheeldon_Apartment_Building_-_Portland_Oregon.jpg'
}]}.to_json

每个循环都知道有多少条记录，但是当浏览器显示

时，字段数据丢失了

Location:
Number of bedrooms:
Location:
Number of bedrooms:
Location:
Number of bedrooms:
Location:
Number of bedrooms:

使用ember 2.5

每个评论由dynamic_cast我将JSON结构更改为此并使其工作。

{
  "data" => [{
    "type" => "rentals",
    "id" => "1",
    "attributes" => {
      "title" => 'Grand Old Mansion',
      "owner" => 'Veruca Salt',
      "city" => 'San Francisco',

      "image" =>     'https://upload.wikimedia.org/wikipedia/commons/c/cb/Crane_estate_(5).jpg'
      }
    },
    {
    "type" => "rentals",
    "id" => "2",
    "attributes" => {
      "title" => 'Urban Living',
      "owner" => 'Mike TV',
