I have a chunk of rhtml that gets reused by several views in several  
controllers. I make partial out of it \_foo and call it with

\<%= render :partial =\>‘bar/foo’ %\>

# RAILS\_ROOT/app/views/bar/\_foo.rhtml

(note I’m not calling with a collection.) Is there a way to send a  
variable to the partial? the doc says i can use :locals =\> { :name =\>  
‘val’ } but what I want to do is alias :name to another variable. I  
can always set some class variable @var and using that inside the  
partial, but I want to make it explicit what it is that I’m passing to  
the partial.

also, is this the way to share something among views? I’m aware of  
layouts but that seems to be for whole page content, rather than  
common snippets.

As usual, you’re on the ball Greg. I was thinking about that very  
resource, but couldn’t remember where I saw it.

Peace,

thank you. excellent article.

an O/T question. what is the font used in the pdf for the code  
portion? it’s a nice fixed monospace font and I’m always on the  
lookout for good monospace fonts to use for coding 🙂 Currently I use  
Lucida Console but it has a problem in that commas and periods look  
too much alike.

That would be Monaco (default monospaced font on a Mac)
