HI Guys,
Problem in a nutshell: In an edge rails app with edge haml, using
content_for in a helper method fails to yield content to the layout.
Here's the relevant pastie:
http://pastie.org/286887
I've been using Haml for awhile now, but have never delved into its
implementation. Recently I was using it with a Rails 2.1.1 app but
needed to upgrade to Edge Rails for a few bug named_scope bug fixes.
Upgrading to edge Rails broke a few things in the view and I think
I've traced it to edge Haml's CaptureHelper#capture_with_haml.
To trace the problem, I created a bare-bones edge rails app with a
layout that contains a 'yield :sidebar' and a helper method that uses
'content_for(:sidebar)' to render a partial into the layout. I noticed
that if I explicitly set @content_for_sidebar, the output showed up
correctly. I then put the regular content_for call back in my template
and manually hacked CaptureHelper#content_for in my frozen edge rails
to explicitly call capture_without_haml (instead of capture) and once
again the output showed up correctly.
So I'm pretty sure the problem is in the Haml implementation of
capture (or further down the callchain) but quickly got lost in Haml's
internals.
Any ideas?
