Question on how to display blocks in Haml? Getting string and nil errors

Hello All,

First off, I love haml/sass and it's changing the way I work
for the
better, but I'm having some problems wrapping my head
around
something.

          <% flash.each do |name, msg| %>
		        <%= content_tag :div, msg, :id =>
"flash_#" %>
		      <% end %>

Take that for example, I can't quite figure out how to make
that
display correctly without getting a "can't convert nil
into String"
error.  Anyone have some advice?

Here's how I'd do it:

- flash.each do |name, msg|
  %div{:id => "flash_#"}= msg

Or, if you want to use content_tag, you might as well make
it a helper:

def flash_display
  flash.each do |name, msg|
    open :div, msg, :id => "flash_#"
  end
end

Then put in your template:

- flash_display
