inherited_resources does both of these automatically (s/model/resource/ for the helper method) - http://github.com/josevalim/inherited_resources/
After having a quick glance at resource_this inherited_resources seems to largely similar but might be easier to override behaviour on one action (though I only glanced at the docs for r_t quickly)
