I was wondering whether someone could show me how to dynamically set the the 'id' attribute in the 'body' tag. I would like to set the id to controller name (in lowercase) using embedded ruby.
<body id="xxxx">
</body>
cheers

thxs Rimantas. Just tried it and it works a treat. So basically i can
place <%= %> expression anywhere within quotes and it will get evaluated
before generating the XHTML.

Well, in this case it just happen that you need to have output
something between quotes.
In templates you can use ERB wherever you need.
You may want to read ERB section here
http://api.rubyonrails.com/classes/ActionView/Base.html
and also "Recognized tags"
http://stdlib.rubyonrails.org/libdoc/erb/rdoc/classes/ERB.html
This should give you a general idea, how it works. Keep in mind that
second link is to
the general documentation of ERB, not rails specific.
