rendering partials from other controllers

Just include the directory name, so if you have app/views/foo/_foo.rhtml, then:
render :partial=>'foo/foo'



1 thing I started doing about a month ago is putting all of my
partials in the layouts directory.

Then, they are all in one place and easy to find later.

Maybe it would make sense to create a partials directory.

The layouts directory is good though. Usually I only have
about 3 or 4 or 5 layouts in there anyway.
