Oh, I should have caught that before! The trick is that there are two ways
of getting text to the output buffer. The first is to use "=" and include it
as a string; the second is to directly write to the buffer. Haml code
directly writes to the buffer, so when you call "yield", that's what's
happening. There are two ways around this. You can either capture the Haml
as a string and use that:
def round_corners
"<div class='rc'>#{capture { yield }}</div>"
end
Or you can use the "open" helper to create your tags, which will write to
the buffer:
def round_corners
open 'div', :class => 'rc' { yield }
end
This way is more elegant and thus recommended. Note that it won't output
anything, so you'll want to have
- round_corners do
%span some text
in your view.
