Adding extension to URL: Rails

Question

I'm setting up some link_to xml views within a rails app. How can the url display the .xml extension?

Need it to appear as:
http://localhost:3000/test/1-testing.xml

Currently it appears as:
http://localhost:3000/test/1-testing

Assuming you want to link to the instance @test, try:

test_url(@test, :format => :xml)
