I have a need to get routes into my AR models, but I can not find the  
module that provides them to ActionController. For example, I would  
like to provide an event feed from two different locations, so want to  
do something like this;

xml.instruct! :xml, :version =\> ‘1.0’  
xml rss stuff  
@events.each do |event|  
event.to\_rss(xml)  
end

Event.rb  
def to\_rss(xml)  
xml.item do  
xml.link(event\_url(self))  
xml.guid(event\_url(self))  
end  
end

but AR (rightly) doesn’t know how to do event\_url() Where does it  
come from?

Thanks,
