You know how when you are using the new resource features in Rails 1.2  
it  
will create all these helper methods for you. Like if I had a resource  
for  
my `Comment` class I’d get `comments_url`, `comments_path`,  
`comment_path(1)`, etc. Well let’s say I’m trying to dry up my views –  
some  
of these crud pages are just very repetitive – how do I call a helper  
based  
on a string I create. I’d like to create a string like  
`object.class.to\_s.downcase.pluralize + ‘\_url’ and then call that  
helper.  
How can I do this?
