need to render several html snippets in different places inside a hamlet template
in my default-layout.hamlet:
!!!
<html lang="en">
<head>
<meta charset="utf-8">
<title>#{pageTitle pc}
^{pageHead pc}
<body>
<div id="main">
<div id="header">
????
<div id="content">
^{pageBody开发者_如何学运维 pc}
from a handler function, I need to replace the ???? above with some HTML contents.
how is this done?
thanks for any input.
EDIT:
I am looking for functionality similar to, for example, django's template blocks. I can define a block inside a template and the handler that uses this template for rendering, can fill in the template's blocks with the needed contents. Right now, yesod has effectively a single block in a template's body. that "defined" by the call ^{pageBody pc}. I know I can build up the output generated by pageBody any way I want using addWidget etc., but right now I will need to output my <div id="header"> and <div id="content"> too and I want to avoid that because all my handlers will have to output these div's to have the same markup structure in all the pages.
I think the answer is to define a function besides defaultLayout. The only thing that's magical about defaultLayout is that subsites (e.g., auth) and error messages use it by default. But you could define a "myDefaultLayout" that takes the other pieces of content you want. You could even define a helper function that wraps up the extra blocks into a single block and then passes that to defaultLayout.
