How to get a named route from a class in rails?

I have a common partial for index where i want to insert some links. On this links i would like to use the named_routes, like

link_to "Say hi",things_path(:param1=>:hello, :params2=>:there)

but i dont know if things_path is users_path, places_path or reviews_path, because this partial is shared for all controllers. There is any way to get the named route associated to the class or the current controller. I want something like this

link_to "Say hi", path_of(@current_class)(:param1=>:hello, :params2=>:there)

A path helper like cars_path is ultimately just a shortcut to setting :controller, :action and other params like :id. If you want to make the controller always equal to the current controller you can just say

link_to "Say hi", :action => "index", :param1=>:hello, :params2=>:there

Because the :controller option is omitted, it will be assumed to be the current controller.

There are several approaches to this. The simplest thing is to rely on polymorphic routing, such as: link_to "Say hi", @my_object. In this case rails will look at the class of @my_object and its current state (new_record?) and use the appropriate route and restful action. Assuming your partial is named _foo.html.erb then this can be as simple as

link_to 'Say hi', foo

... which is pretty awesome. This question has been asked before, here: Polymorphic Routes in Rails - in views but I guess it's hard to find answers without knowing the magic words "polymorphic routing" :-)
