Dynamically construct RESTful route using Rails

I'm trying to write a helper method that accepts the name of a plural resource and returns a corresponding link. The essence of the method is:

def get_link(resource)
  link_to "#{resource.capitalize}", resource_path
end

—Clearly the resource_path part above doesn't work. What I'd like is to be able to pass foos to get foos_path and bars to get bars_path etc. How can I do that? I can't quite work out the syntax.

If you want to construct a RESTful route with a member:

send("edit_#{resource}_path".to_sym, @resource)

def get_link(resource)
  link_to(resource.to_s.titleize, send("#{resource}_path"))
end

The to_s call on resource is to support passing symbols as resource. So 

get_link("foos")

will work and also 

get_link(:foos)
