我正在使用 ember django 适配器，因为我的后端是在 python/django 中设计的。（http://dustinfarris.com/ember-django-adapter/）

feed.js（模型） 

import DS from 'ember-data';

const {attr} = DS

export default DS.Model.extend({
     gallery_name:attr('string'),
     thumbnail_url:attr('string'),
     is_following:attr('boolean'),
     time:attr('string'),
     description:attr('string'),
     feedPhotos:DS.hasMany('feedPhoto',{embedded:'always'})
});

feedphoto.js(模型)

import DS from 'ember-data';

export default DS.Model.extend({
  feed: DS.belongsTo('feed'),
  url: DS.attr(),
  profilePic: DS.attr(),
  userName: DS.attr(),
  userKarma: DS.attr(),
  caption: DS.attr(),
  numComments: DS.attr(),
  owner: DS.attr(),
  time: DS.attr(),
  photo_url: DS.attr(),
  comments_url: DS.attr(),
  numFives: DS.attr(),
  fivers_url: DS.attr(),
  fivers_pk: DS.attr(),
  fullphoto_url: DS.attr(),
  fullphoto_pk: DS.attr(),
  is_fived: DS.attr('boolean'),
  hiFiveKarma: DS.attr(),
  owner_pk: DS.attr(),
  userFirstName: DS.attr(),
  is_bookmarked: DS.attr('boolean')
});

feed.js（序列化器）

import DRFSerializer from './drf';
import DS from 'ember-data';

export default DRFSerializer.extend(DS.EmbeddedRecordsMixin,{
  primaryKey: 'pk',
  attrs:{
    feedPhotos:{ embedded: 'always' }
  }
});

feedphoto.js(serailizer)

import DRFSerializer from './drf';
import DS from 'ember-data';

export default DRFSerializer.extend({
  primaryKey: 'pk',
});

响应.json

        "owner_pk": 34,
        "userFirstName": "Shushma",
        "is_bookmarked": false
    }]
}]

该代码能够保存 feed 模型的详细信息，但不能保存 feedphoto 模型。在我的 ember 检查器中，feed 模型显示了正确的数据。但是 feedphoto 模型没有显示任何数据。我不知道为什么我会出错。

我认为你有两个问题

  1. 中的大写字母：DS.hasMany('feedPhoto',{embedded:'always'}). 这意味着您的模型文件应命名为“feed-photo.js”或“feed_photo.js”。
  2. 另外，我还没有使用过 ember-django-adapter，但他们通常将feed_photos即将到来的响应解释为feedPhotoember 关系。因此，您可能应该feed_photos从您的服务器返回，而不是feedPhotos将属性重命名为feedphotos
