流星:没有路径可解决路径错误.如何在嵌套对象中访问单篇文章 [英] Meteor: There is no route for the path error. how to access SINGLE article within a nested object

问题描述

我有10个对象类别"的数组，每个类别都有子对象，例如该类别中的帖子.这就是它的样子.

I have an array of 10 objects 'categories' and each category has sub objects such as posts within that category. This is how it looks.

我这样访问类别列表.

<template name="CategoriesMain">
  {{#each articles}}
    <li>
      <a href="/unfiltered/{{_id}}"><h2>{{name}}</h2></a>
    </li>
  {{/each}}
</ul>
</template>

此链接

<a href="/unfiltered/{{_id}}"><h2>{{name}}</h2></a>

访问类别如下的帖子"列表

accesses the 'posts' list within the category which looks like this

<template name="CategoriesSingle">

<h1>This is a test</h1>
<ul>
  {{#each articles}}
  {{#each posts}}
    <li>
      <a href="/catsingle/{{_id}}"><h2>{{title}}</h2></a>
    </li>
    {{/each}}
  {{/each}}
</ul>
</template>

该链接应该以类别

<a href="/catsingle/{{_id}}"><h2>{{title}}</h2></a>

问题:

我得到一个错误:路径:/catsingle/没有路径，当我尝试访问单个帖子时

I get the error: There is no route for the path: /catsingle/ when ever i try to access the SINGLE POST

即使我这样在我的route.js中也有

even though i have it in my routes.js like this

FlowRouter.route('/catsingle/:_id', {
    name: 'catsingle',
    action() {
        BlazeLayout.render("AppLayout", {main: "CategoryArticleSingle"});
    }
});

模板助手看起来像这样

  Template.CategoryArticleSingle.helpers({
      articles: function () {
        var id = FlowRouter.getParam('_id')
        return CategoryCollection.findOne({_id: id});
      }
    });

我如何在某个类别中成功发布单个帖子?

How can I successfully the single post within a category?

推荐答案

您的posts数组没有_id键，它具有ID键.

Your posts array doesn't have an _id key, it has an ID key.

尝试:

<a href="/catsingle/{{ID}}"><h2>{{title}}</h2></a>
