杰基尔的类别页面 [英] Category Page in Jekyll

问题描述

我有一个category.html页面，该页面将循环浏览某些类别的帖子.

I have a category.html page that will loop through a certain category of posts.

{% for post in site.categories.tech %}

当用户单击

{{ post.categories }}

这是通过显示所有帖子的循环生成的.

Which is generated from a loop that displays all of the posts.

{% for post in site.posts %}

我需要该{{ post.categories }}变量来替换categories.html中的.tech

I need that {{ post.categories }} variable to replace the .tech in the categories.html like this

{% for category in site.categories.{{ post.categories }} %}

我不知道如何将变量从index.html传递到categories.html

I don't know how to pass the variable from index.html to categories.html

推荐答案

站点类别是一个对象，其中每个键都是类别名称.所以

Site categories is an object where each key is the category name. So

{{ site.categories }}

输出如下内容:

{
  "Category name" => [#, #, #, #, #, #, #],
  "Another category name" => [#, #, #, #, #, #, #],
  ...
}

因此，方括号应该这样做.因此，如果您将index.html放在首位，那么

Therefore, square brackets should do it. So if in the front matter of your index.html you have

---
categories: tech
---

下面的代码将呈现您所有属于技术类别的帖子.

The code below will render all your posts under tech category.

{% for post in site.categories[post.categories] %}
  {{ post }}
{% endfor %}

如果您在前面有多个类别，那么这当然行不通，但是我不知道您的用例.

Of course this won't work if you have multiple categories in the front matter, but I don't know your use case.
