Jekyll和嵌套列表的YAML首要问题
Jekyll和嵌套列表的YAML首要问题
提问于 2012-10-06 23:35:23
我有一组嵌套的yaml列表，如下所示：
title: the example
image: link.jpg
products:
- top-level: Product One
arbitrary: Value
nested-products:
- nested: Associated Product
sub-arbitrary: Associated Value
- top-level: Product Two
arbitrary: Value
- top-level: Product Three
arbitrary: Value我可以使用for item in page.products顺利地遍历产品，并且可以使用逻辑运算符来确定是否存在嵌套产品--我不能做的是在每次top-level迭代中遍历多个nested-products
我试过使用for subitem in item和其他选项--但我不能让它工作--有什么想法吗？

我刚刚写的这个例子(叫做index.html)
---
title: the example
products:
- top-level: Product One
arbitrary: Value
nested-products:
- nested: Associated Product
sub-arbitrary: Associated Value
- nested: Another associate
sub-arbitrary: with its associated value
- top-level: Product Two
arbitrary: Value
nested-products:
- nested: nested product Two
sub-arbitrary: Two's nested's associate value
- top-level: Product Three
arbitrary: Value
- top-level: Product Four
arbitrary: SomeValue

<!-- index.html -->
<!DOCTYPE html>
<html lang="en">
<head>
<title>{{ page.title }}</title>
</head>
<body>
<h4>products:</h4>
<ul>{% for product in page.products %}
<li>{{ product.top-level }}: {{ product.arbitrary }}{% if product.nested-products %}
<ul>
{% for nestedproduct in product.nested-products %} <li>{{ nestedproduct.nested }}: {{ nestedproduct.sub-arbitrary }}</li>
{% endfor %}</ul>
{% endif %}</li>{% endfor %}
</ul>
<p>Hope that answers it</p>
</body>
</html>生成以下内容：
<!-- index.html -->
<!DOCTYPE html>
<html lang="en">
<head>
<title>the example</title>
</head>
<body>
<h4>products:</h4>
<ul>
<li>Product One: Value
<ul>
<li>Associated Product: Associated Value</li>
<li>Another associate: with its associated value</li>
</ul>
</li>
<li>Product Two: Value
<ul>
<li>nested product Two: Two's nested's associate value</li>
</ul>
</li>
<li>Product Three: Value</li>
<li>Product Four: SomeValue</li>
</ul>
