ember js从json获取元信息 [英] ember js get meta informations from json
本文介绍了ember js从json获取元信息的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我的服务器上有一个json数据:
{
post:{
id:1,
title:Progressive Enhancement is Dead,
comments:[1,2],
links:{
user:/ people / tomdale
}
},
meta:{
total:100
}
}
看起来完全像文档( https://guides.emberjs.com/v2.5.0/models/handling-metadata/ )我试着获取不成功的元对象
导出默认值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;
}
});
解决方案
您正在使用findAll方法,它不支持元数据。如果要使用元数据获取多个帖子,则应该使用 this.store.query('post',{/ * params * /})
p>
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
}
}
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;
}
});
解决方案
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.
