ember js 从 json 获取元信息 [英] ember js get meta informations from json

问题描述

我有一个来自我的服务器的 json 数据:

i have a json data from my server:

{
  "post": {
    "id": 1,
    "title": "Progressive Enhancement is Dead",
    "comments": ["1", "2"],
    "links": {
      "user": "/people/tomdale"
    }
  },

  "meta": {
    "total": 100
  }
}

看起来和文档完全一样(https://guides.emberjs.com/v2.5.0/models/handling-metadata/) 我尝试获取元对象但没有成功

look exactly like the documentation (https://guides.emberjs.com/v2.5.0/models/handling-metadata/) i try to get the meta object with no success

export default Ember.Route.extend({
  model() {
    var data = this.store.findAll('post');
    data.then((result) => {
      let meta = result.get('meta');
      console.log(meta); //this return me undefined
    })
    return data;
  }
});

推荐答案

您使用的 findAll 方法不支持元数据.如果您想获取多个带有元数据的帖子，您应该改用 this.store.query('post', {/*params*/}) 方法.

You are using findAll method and it does not support meta data. You should use this.store.query('post', {/*params*/}) method instead, if you want to get multiple posts with meta data.
