Hello
I've had some troubles when child templates need to provide some content
for the parent templates.
My first approach was setting $var in child template, and access it from
parent template. But this approach has obvious limitation: you cannot
provide more complex content than just one string (yes you can by setting
$var to sub-sub-template output, but this is not flexible).
Instead of this I implemented a special content_for code block, that
outputs contents to web.ctx, so then parent templates may output them.
Child template:
$content_for("header"):
> <p>Some content for header</p>
Parent template:
$:content_for("header")
I've put the code in this issue
https://github.com/webpy/webpy/issues/192#issuecomment-10693336
My first implementation was dirty, but then I found out how to make it
nicer by hiding functionality in generated template code
I'm not sure if this feature can make its way in web.py code, but I'd like
to get some feedback from web.py users.
