Overview

ActionView handler for .rsx templates: app/views/users/show.html.rsx

The handler returns Ruby source, which ActionView compiles into a method on the view context. That means a .rsx view is compiled once per process and every Rails helper (url helpers, t, form builders, CSRF tags) is available directly, because self inside the template is the view.
