无法序列化 ember 数据中的后端响应

如何解决无法序列化 ember 数据中的后端响应

我正在尝试访问响应中的分页变量，例如我的控制器内的 page_number、total_pages，因为我刚刚将这个功能引入了后端的这个遗留代码，现在我被卡住了如何读取这些数据然后去进一步。

我的序列化程序代码

import DS from 'ember-data';


var underscore = Ember.String.underscore;
export default DS.RESTSerializer.extend(DS.EmbeddedRecordsMixin,{
  attrs: {
    rules: {
      embedded: 'always'
    },test_cases: {
      serialize: "id",deserialize: 'records'
    },},keyForRelationship: function (rawKey) {
    return underscore(rawKey) + "_id";
  }
})

route.js

import Route from '@ember/routing/route';
import { hash } from 'rsvp'
import ResetScrollMixin from 'admin-frontend/mixins/reset-scroll-mixin'
export default Route.extend(ResetScrollMixin,{

  model(params) {
    return hash({
      ruleSetVersions: this.store.query('rule-set-version',{
        rule_set_id: params.rule_set_id,is_archived: false,page: '1'
      }),ruleSet: this.store.findRecord('rule-set',params.rule_set_id)
    })
  }
});

响应 json 看起来像

{
    "page_number": 1,"page_size": 5,"rule_set_versions": [{
        "id": 930,"last_updated_by": 1,"created_by": 1,"default_rule_id": 963,"is_live": true,"is_archived": false,"start_time": "2020-12-30T18:30:00Z","rule_set_id": 11,"rules": [{

    }],"total_entries": 3,"total_pages": 1
}

我能够读取和解析 rule_set_versions 数组中的所有数据，但我无法访问它之外的分页参数。
