在Meteor中访问模板渲染函数中的父数据上下文

Question

I have the following parent template:

<template name="parentTempl">
    {{#each child}}
       {{> childTempl}}
    {{/each}}
</template>

I want to access the parent data context in childTempl :

Template.childTempl.rendered = function() {
    console.log(this.parent.data); // ?
};

How can I do this? Any help would be greatly appreciated.

You can use Template.parentData(n) to access the parent context inside any template helper or rendered callback. See the docs here . Internally, all it does is call the Blaze getView method for the parent view until it hits the desired parent context (as defined by n).
