Jekyll按类别显示收藏 [英] Jekyll display collection by category

问题描述

我无法弄清楚如何按类别对集合的内容进行排序.我发现了一个关于如何按类别对帖子进行排序的非常相似的问题，但是它似乎不适用于

I'm having trouble figuring out how to sort the content of a collection by category. I've found a very similar question on how to sort posts by category but it doesn't seem to work with collections Jekyll display posts by category.

比方说，我有一个名为汽车"的收藏，分为两个类别:旧"和新".如何仅显示旧"类别的汽车?

Let's say I have a collection called 'cars' with two categories: 'old' and 'new'. How can I display only cars with the category 'old'?

推荐答案

您可以像对任何其他对象(如页面或帖子)那样对集合进行排序，分组或过滤.

You can sort, group or filter collection like any other object like page or posts.

_my_collection/mustang.md

---
category: 'old'
abbrev: tang
---
mustang content

_my_collection/corvette.md

---
category: 'new'
abbrev: vet
---
corvette content

过滤

{% assign newcars = site.my_collection | where: "category", "new" %}

排序

{% assign allcarssorted = site.my_collection | sort: "category" %}

分组

{% assign groups = site.my_collection | group_by: "category" | sort: "name" %}

这会将您的汽车分组，然后按类别(即类别)对分组进行排序.

This groups your cars and then sort groups by name that is the category.

{% for group in groups %}
    {{ group.name }}
    {% for item in group.items %}
        {{item.abbrev}}
    {%endfor%}
{%endfor%}
