使用Flow Router访问父模板数据 [英] Access parent template data with Flow Router

问题描述

我切换到Flow Router，但遇到了问题.如何访问父模板数据?使用Iron Router，数据来自路由器，并且在模板内部可用，因此，如果我要访问父数据，Template.parentData()可以正常工作. 但是在Flow Router中，数据不是来自路由器，而是来自助手，而Template.parentData()不再包含数据！

I switched to Flow Router and I have a problem. how can I access the parent template data? with Iron Router the data was coming from router and was available inside the template, so if I wanted to access a parent data Template.parentData() was working. But in Flow Router the data is not coming from router, it comes from helpers and Template.parentData() doesn't have the data in it anymore!

<template name="myTemplate">
    {{#if Template.subscriptionsReady}}
      {{> showPost parentPost }}
      {{> newPost }}
    {{/if}}  
</template>

Template.myTemplate.helpers({
    parentPost: function(){ return Posts.findOne({...})}
});

Template.newPost.events({
    'submit .js-new-post':function(event,template){
         console.log(Template.parentData(1).parentPost);
}});

推荐答案

您需要将该数据传递到模板.

You need to pass that data through to the Template.

例如{{> newPost parentPost=mydatahere}}
