在雨果模板中，如何在.site.data上进行查找。假设我有这样的数据结构：

{
    "my-blog-post": {
        "Version": 21,
        "Revision": 0,
        "Code": "my-blog-post",
        "Name": "My Blog Post",
        "Parent": "the-parent-post"
    },
    "another-post": {
        "Version": 21,
        "Revision": 0,
        "Code": "another-post",
        "Name": "Another Post",
        "Parent": "the-parent-post"
    }

}

在博客文章的详细信息页面内，我想获取所有以当前帖子为父的帖子的列表。基本上，我想查询具有“父母库”作为父字段的价值的帖子。我可以使用范围来实现这一目标，但我需要使用它们来使用它们。我尝试了这样的表情，但没有快乐。

{{$child_posts := where (where .Site.Data "Section" "blog") "Parent" "the-parent-post" }}

我可以做到这一点：

{{$posts := where $site.Pages "Section" "blog"}}
{{ range sort $posts "Name" "asc" }}
    {{ $post := . }}
    {{if eq $post.parent $currentPage.Code}}
          ...Do something...
    {{end}}
{{end}}

但这不是理想的，而不是我需要的。提前致谢。

In a hugo template how can I do a lookup on .Site.Data. Assuming I have a data structure like this:

{
    "my-blog-post": {
        "Version": 21,
        "Revision": 0,
        "Code": "my-blog-post",
        "Name": "My Blog Post",
        "Parent": "the-parent-post"
    },
    "another-post": {
        "Version": 21,
        "Revision": 0,
        "Code": "another-post",
        "Name": "Another Post",
        "Parent": "the-parent-post"
    }

}

Inside the detail page for a blog post, I would like to get the list of all the posts that have the current post as the parent. Basically I would like to query posts that have "the-parent-post" as the value of Parent field.
I can achieve this using range but I need to get them using where.
I experimented with expressions like this but no joy.

{{$child_posts := where (where .Site.Data "Section" "blog") "Parent" "the-parent-post" }}

I can do this:

{{$posts := where $site.Pages "Section" "blog"}}
{{ range sort $posts "Name" "asc" }}
    {{ $post := . }}
    {{if eq $post.parent $currentPage.Code}}
          ...Do something...
    {{end}}
{{end}}

But it is not ideal and not what I need.
Thanks in advance.
