Rails - Jul 2006 - From the Agile book, page 144 regarding a div tag helper

Hi. in the Rails Agile book here''s what was happening:
 >>>
module StoreHelper
def hidden_div_if(condition, attributes = {})
if condition
attributes["style" ] = "display: none"
end
attrs = tag_options(attributes.stringify_keys)
"<div #{attrs}>"
end
# format_price method ...
end

Note that we cheated slightly here. We copied code from the Rails 
standard
helper called content_tag( ); that?s how we knew to call tag_options( ) 
the way
we did.And how did we find the source code of the content_tag( ) method? 
We brought up the
RDoc documentation in a browser and clicked the View Source
link.
>>>
This just flew gracefully over my head..(duuugh)..

I was at the RDDoc site, and nothing pertaining to helper methods, or a 
source containing ''content_tag()'' was found..

So my question is which source file did Dave talk about? and how often 
would we have to do this kind of trick..

Thanks
