我如何使用widgetFile在另一个文件中包含一个hamletfile? [英] How can I include an hamletfile inside another using widgetFile?

问题描述

出于可重用性，我想在另一个内部重用一个小部件.例如，小部件文件blogpost.hamlet可以包含帖子的显示方式，而blog.hamlet可以包含完整的博客.

For reusability, I want to re-use a widget inside another. For instance, the widget file blogpost.hamlet could contain how a post is displayed, and blog.hamlet could contain the full blog.

blog.hamlet的以下内容不起作用:

$forall post <- posts
    ^{widgetFile "blogpost")

那么，将一个小部件嵌入另一个小部件的正确语法是什么?

So, what is the correct syntax to embed one widget inside another?

推荐答案

Hamlet语法不支持将模板Haskell拼接嵌入其中，这使您想要执行的代码无法实现.相反，您需要在Haskell中创建一个辅助函数，例如:

The Hamlet syntax does not support embedding Template Haskell splices inside of it, which makes the code you're looking to do impossible. Instead, you need to create a helper function in Haskell, e.g.:

blogpost post = $(widgetFile "blogpost")

然后在blog.hamlet中，您可以:

Then in blog.hamlet, you can have:

$forall post <- posts
    ^{blogpost post}
