我正在尝试在我的Jekyll网站中创建一个页面,该页面将显示一个自定义变量并列出包含该自定义变量的帖子.
我使用模板Thiago Rossener创建了一个电影评论博客：
蒂亚戈的模板：https://github.com/thiagorossener/jekflix-template
我的网站：https://www.howdareyoureview.com/
在每篇文章中,我都在YAML前面的内容中定义了与电影细节相关的自定义变量(即演员,导演得分等).
例如：
--- layout: post title: "Baby Driver" image: 'https://res.cloudinary.com/how-dare-you-review/image/upload/c_fill,h_399,w_760/v1529865791/baby-driver.png' tags: - action score: 72 director: Edgar Wright written-by: Edgar Wright staring: - Ansel Elgort - Lily James - Eiza González - Jon Hamm - Jamie foxx ---
我想创建与此模板中已存在的标签页完全相同的页面：
https://www.howdareyoureview.com/tags/
除了我想要按导演,主演等排序,而不是标签.
使用tags.html文件中的以下代码创建标签页：
---
layout: minimal
title: "#Tags"
permalink: /tags/index.html
description: "Procure por sua #tag favorita."
---
<div class="tags">
{% assign tags_list = site.tags %}
{% if tags_list.first[0] == null %}
{% for tag in tags_list %}
<a href="#{{ tag | slugify }}">{{ tag }}</a>
{% endfor %}
{% else %}
{% for tag in tags_list %}
<a href="#{{ tag[0] | slugify }}">{{ tag[0] }}</a>
{% endfor %}
{% endif %}
{% assign tags_list = nil %}
</div>
{% for tag in site.tags %}
<div class="tag-wrapper">
<span class="tag-title" id="{{ tag[0] | slugify }}">{{ tag[0] }}</span>
<ul class="post-list">
{% assign pages_list = tag[1] %}
{% for post in pages_list reversed %}
{% if post.title != null %}
{% if group == null or group == post.group %}
<li><a href="{{ site.url }}{{ post.url }}">{{ post.title }}<span class="entry-date"><time datetime="{{ post.date | date_to_xmlschema }}" itemprop="datePublished">{{ post.date | date: "%m/%d/%Y" }}</time></a></li>
{% endif %}
{% endif %}
{% endfor %}
{% assign pages_list = nil %}
{% assign group = nil %}
</ul>
</span>
</div>
{% endfor %}
为了实现我创建的自定义变量,我尝试用director替换“tag / tags”并将文件保存到根目录中作为“directors.html”,但页面为空白.
---
layout: minimal
title: "#Directors"
permalink: /directors/index.html
description: "Procure por sua director favorita."
---
<div class="directors">
{% assign directors_list = site.director %}
{% if directors_list.first[0] == null %}
{% for director in directors_list %}
<a href="#{{ tag | slugify }}">{{ director }}</a>
{% endfor %}
{% else %}
{% for director in directors_list %}
<a href="#{{ director[0] | slugify }}">{{ director[0] }}</a>
{% endfor %}
{% endif %}
{% assign directors_list = nil %}
</div>
{% for director in site.director %}
<div class="director-wrapper">
<span class="director-title" id="{{ tag[0] | slugify }}">{{ director[0] }}</span>
<ul class="post-list">
{% assign pages_list = director[1] %}
{% for post in pages_list reversed %}
{% if post.title != null %}
{% if group == null or group == post.group %}
<li><a href="{{ site.url }}{{ post.url }}">{{ post.title }}<span class="entry-date"><time datetime="{{ post.date | date_to_xmlschema }}" itemprop="datePublished">{{ post.date | date: "%m/%d/%Y" }}</time></a></li>
{% endif %}
{% endif %}
{% endfor %}
{% assign pages_list = nil %}
{% assign group = nil %}
</ul>
</span>
</div>
{% endfor %}
由于代码和概念与填充标记的方式完全相同 – 我无法理解为什么这不起作用 – 我希望有人可以提供帮助！
这是我的整个目录供参考：

解决方法
标签页使用site.tags,这是一个按标签分组的site.posts数组,由Jekyll在生成时创建.
您试图通过定位site.directors来复制,但此预期的数组不存在.但是,您可以使用group_by过滤器来实现您的目标.
<div class="directors">
{% assign directors = site.posts | group_by: 'director' | sort: "name" %}
{% for director in directors %}
{% if director.name == "" %}
{% assign name = "Anonymous" %}
{% else %}
{% assign name = director.name %}
{% endif %}
<a href="#{{ name | slugify }}">{{ name }}</a>
{% endfor %}
</div>
{% for director in directors %}
<div class="director-wrapper">
{% if director.name == "" %}
{% assign name = "Anonymous" %}
{% else %}
{% assign name = director.name %}
{% endif %}
<span class="director-title" id="{{ name | slugify }}">{{ name | debug }}</span>
<ul class="post-list">
{% assign pages_list = director.items %}
{% for post in pages_list reversed %}
<li><a href="{{ site.url }}{{ post.url }}">{{ post.title }}<span class="entry-date"><time datetime="{{ post.date | date_to_xmlschema }}" itemprop="datePublished">{{ post.date | date: "%m/%d/%Y" }}</time></a></li>
{% endfor %}
</ul>
</span>
</div>
{% endfor %}
提示：您可以使用inspect过滤器来调试变量. {{myvar |检查}}
