#
# url_for :controller => 'posts', :action => nil
#
# If you explicitly want to create a URL that's almost the same as the current URL, you can do so using the
# :overwrite_params options. Say for your posts you have different views for showing and printing them.
# Then, in the show view, you get the URL for the print view like this
#
# url_for :overwrite_params => { :action => 'print' }
#
# This takes the current URL as is and only exchanges the action. In contrast, <tt>url_for :action => 'print'</tt>
# would have slashed-off the path components are the changed action.
#
# Instead of passing an options hash, you can also pass a method reference in the form of a symbol. Consider this example:
#
# class WeblogController < ActionController::Base
