Ancestors 祖先

Returns a collection of Page objects, one for each ancestor section of the given page. 返回 Page 对象的集合，给定页面的每个祖先部分对应一个 Page 对象。

With this content structure: 采用此内容结构：

content/
├── auctions/
│   ├── 2023-11/
│   │   ├── _index.md     <-- front matter: weight = 202311
│   │   ├── auction-1.md
│   │   └── auction-2.md
│   ├── 2023-12/
│   │   ├── _index.md     <-- front matter: weight = 202312
│   │   ├── auction-3.md
│   │   └── auction-4.md
│   ├── _index.md         <-- front matter: weight = 30

│   └── payment.md
├── books/
│   ├── _index.md         <-- front matter: weight = 10
│   ├── book-1.md
│   └── book-2.md
├── films/

└── _index.md

And this template:

{{ range .Ancestors }}
  <a href="{{ .RelPermalink }}">{{ .LinkTitle }}</a>
{{ end }}

On the November 2023 auctions page, Hugo renders:

<a href="/auctions/2023-11/">Auctions in November 2023</a>
<a href="/auctions/">Auctions</a>
<a href="/">Home</a>

In the example above, notice that Hugo orders the ancestors from closest to furthest. This makes breadcrumb navigation simple:

<nav aria-label="breadcrumb" class="breadcrumb">
  <ol>
    {{ range .Ancestors.Reverse }}
      <li>
        <a href="{{ .RelPermalink }}">{{ .LinkTitle }}</a>
      </li>
    {{ end }}
    <li class="active">
      <a aria-current="page" href="{{ .RelPermalink }}">{{ .LinkTitle }}</a>
    </li>
  </ol>
</nav>

With some CSS, the code above renders something like this, where each breadcrumb links to its page:

使用一些 CSS，上面的代码会呈现如下内容，其中每个面包屑都链接到其页面：

Home > Auctions > Auctions in November 2023 > Auction 1
