Random Haml tips

1. Multiline code block with |

= link_to "Back", root_path,            |
   :class => "back", :accesskey => "b", |
   :title => "Go back (ctrl-b)"         |

Although for this example, you'll be better off creating helper method for it.

2. Two types of comment

Make sure you use the one you need.

/ this will be translated to HTML comment, visible to anyone 

-# and this will not, so use this one for dev. notes 

3. One-liners

Not very pretty, but they do the job.

== #{label_tag "Email"}:

= label_tag('Email'), ':'

4. Use &= to sanitize any HTML-sensitive characters

Not that anything is wrong with h(), but I like this better.

%p
  &= @comment.body
