布局中的 Front Matter 数据不起作用 Eleventy

Question

我在布局中使用 front matter 时遇到问题。它只是显示页面的前端内容，而不创建我的布局所需的数据。

代码如下：

/src/_includes/layouts/base.html

---
rightLinks : [
        {
            "icon": "mail_outline",
            "href": "https://google.com"
        }
    ]
---
<!DOCTYPE html>
<html lang="es-AR">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>{{ title }}</title>
  <link href="https://fonts.googleapis.com/icon?family=Material+Icons"
      rel="stylesheet">
  <link rel="preconnect" href="https://fonts.googleapis.com">
<link rel="preconnect" href="https://fonts.gstatic.com" crossorigin>
<link href="https://fonts.googleapis.com/css2?family=Source+Sans+Pro:ital,wght@0,300;0,400;0,600;0,700;0,900;1,300;1,400;1,600;1,700;1,900&display=swap" rel="stylesheet">
  <link rel="stylesheet" href="/css/global.css">
</head>
<body>
  <!-- top-nav try to use rightLinks data from this layout -->
  {% include "partials/top-nav.html" %}
  {% include "partials/main-nav.html" %}
  <main tabindex="-1" id="main-content">{% block content %}{% endblock %}</main>
</body>
</html>

/src/_includes/layouts/home.html

{% extends "layouts/base.html" %} 
{% block content %}

<section class="hero is-black is-fullheight-with-navbar hero-home">
  <div class="hero-body">
    <div class="container">
      <div>
        <h1 class="title text-black text-huge">
          Nexus Materiales Eléctricos
        </h1>
        <h2 class="subtitle is-4">
          Somos mayoristas en insúmos eléctricos de calidad.
        </h2>
      </div>
      <div class="mt-6">
        <a href="/marcas" class="button is-rounded is-large is-dark is-uppercase text-semi-black">
          ver marcas
        </a>
      </div>
    </div>
  </div>
</section>

<section class="section has-background-white">
  <h2 class="title">Nuestras marcas destacadas</h2>
  <h3 class="subtitle">Calidad y seguridad</h3>
</section>

{% endblock %}

/src/index.md

---
title: 'Hello World!'
layout: 'layouts/home'
---

我得到的视觉结果是顶部的实际字符串：

在我看来，Eleventy 出于某种原因跳过了前面的内容。

这是我的 Eleventy 配置文件：

module.exports = function(config) {
    config.addWatchTarget("./src/sass/");
    config.addPassthroughCopy('./src/images')

    // Return your Object options:
    return {
        dir: {
            input: "src",
            output: "dist"
        },
        markdownTemplateEngine: 'njk',
        dataTemplateEngine: 'njk',
        htmlTemplateEngine: 'njk',
    }
  };

有人可以向我解释为什么会这样，我该如何解决？谢谢

Front-matter 数据仅在页面直接引用的布局文件中可用 layout: front matter key，not with Nunjucks {% extends %} .直接引用的布局文件中的前题数据作为 11ty's data cascade. (11ty docs: front matter in layouts)

的一部分与其他数据合并

例如：

<!-- index.md -->
---
layout: layouts/content
---
# some content here

{# layouts/base.njk #}
---
hello: "world"
---
{# ^ the above will be printed as plain text and isn't available #}

{# layouts/content.njk #}
---
someKey: "something"
---
{% extends "layouts/base.njk" %}

{{ someKey }}
{# ^ this will render "something" as expected #}

这可能是因为 {% extends %} 是 Nunjucks 的一项功能，Eleventy 不知道哪些其他 Nunjucks 文件被引用。

对于您的情况，您有两种选择。首先，您可以将前题数据放在 layouts/home 中，因为这就是您在 index.md 中引用的内容。另一种选择是只使用 Nunjuck's set tag.

{% set links = [
    {
        "icon": "mail_outline",
        "href": "https://google.com"
    }
] %}

{% for link in links %}
    {{ link.icon }}
    {{ link.href }}
{% endfor %}
