我到处搜索,但似乎无法在这里找到这个简单问题的答案。
问题:
我在一个模型中有一个hasMany关系,该模型由findAll()中的路由加载。根据我在这里看到的很多答案,有效负载看起来很好,但我得到了#34; TypeError:无法读取属性'替换'未定义"。更多细节如下。
我怎样才能让这个有很多关系起作用?我使用asynch:false并按照建议发送了sideload。
使用:Ember 2.1.0,Ember-Data 2.1.0。

路线:
应用程序/路由/ search.js
export default Ember.Route.extend({
model(params) {
if(params.query){
return this.store.findAll('search-result');
}
return null;
},
actions:{
sendSearch: function(queryString){
this.store.unloadAll('search-result');
this.refresh();
}
}
});
型号:
应用程序/模型/搜索result.js
import DS from 'ember-data';
export default DS.Model.extend({
title: DS.attr('string'),
description: DS.attr('string'),
url: DS.attr('string'),
tags: DS.hasMany('search-result-tag', {async:false})
});
应用程序/模型/搜索结果-tag.js
import DS from 'ember-data';
export default DS.Model.extend({
name: DS.attr('string'),
});
适配器(搜索结果)
import DS from 'ember-data';
export default DS.RESTAdapter.extend({
host: 'http://localhost:8080',
urlForFindRecord(id, modelName, snapshot) {
let url = this._super(...arguments);
let query = Ember.get(snapshot, 'adapterOptions.query');
if (query) {
url += '?' + Ember.$.param(query); // assumes no query params are present already
}
return url;
},
urlForFindAll(modelName) {
var queryDict = {};
location.search.substr(1).split("&").forEach(function(item) {queryDict[item.split("=")[0]] = item.split("=")[1]})
let url = this._super(...arguments);
let query = queryDict['query'];
if (query) {
url += '?query=' + query; // assumes no query params are present already
}
return url;
}
});
