I''m using the haml gem and it''s great, been using it for a
while and I
love it.
I''ve got a problem trying to display the flash messages, if I do the
following:
- if flash[:notice]
#flashNotice
=flash[:notice]
- else if flash[:error]
#flashError
=flash[:error]
- end
I get
You don''t need to use "- end" in Haml. Use indentation
instead:
- if foo?
%strong Foo!
- else
Not foo.
Ok, so I take out "- end" and I get
default.haml:21: syntax error, unexpected $end, expecting kEND
So which is it? What do I have to do to get around this? My
indentation is perfect, so I don''t see what else I can do.
Incidentally this appears to be a new problem with the latest version
of haml. Before I was using "- end" and it worked perfectly.
Any help appreciated.
Thanks
Matt

I realize this isn''t a direct answer to your question but to give you some context I have been using haml since it was first released and I have used in on many many projects. I absolutely cannot go back to rhtml because haml is so much more concise. Still though, I have no idea the answer to your question. Why? Because I had always heard that conditional logic should not be in my views. I realize this is a personal opinion but I figure I would show you how I would handle this: # application_helper.rb # even if flash error doesn''t exist this will return nil (empty as expected) def place_flash_message flash[:notice] ? flash[:notice] : flash[:error] end # view.html.haml = place_flash_message or if I really need conditional logic such as in: if logged_in? something else other thing I would simply create a helper or a helper block with capture. Anyways, in my opinion this improves readability and as a general rule of thumb in 2 years of rails development projects I have never felt the need to stick conditional logic directly in my view. Now assuming you discard all that, I think the correct method is not to put the end in haml which would make more sense in the haml way of doing things. Since I haven''t actually needed to do this, I am not sure the issue.
