First example simplified

The first code example may be simplified, since the call to method to_xml is made implicitly anyway:

def index
  @people = Person.find :all

  respond_to do |format|
    format.html
    format.xml { render :xml => @people }
  end
end

Passing an object as argument

It is possible to pass an instance of a record to the method. See the documentation of polymorphic_url (http://apidock.com/rails/ActionDispatch/Routing/PolymorphicRoutes).
