问题
Is there a way to access YFM properties defined in a child layout in its parent layout?
For example, given a child layout page.hbs:
---
layout: wrapper.hbs
no_header: true
----
<div class="wrapper">{{> body }}</div>
I'd like to access the no_header YFM property defined in page.hbs in the parent layout wrapper.hbs:
<html>
<body>
{{#unless layout.no_header}}<header></header>{{/if}}
{{> body }}
</body>
</html>
回答1:
The front matter merges up so you should be able to get it on the root of the context.
Try doing {{#unless no_header}}.
