prototype-rails provides Prototype, Scriptaculous, and RJS on Rails 3.1 and later.
//= require prototype //= require prototype_ujs //= require effects //= require dragdrop //= require controls
prototype-rails supports RJS debugging. RJS responses are wrapped to catch
exceptions, alert() them, and re-raise the exception. Debugging is disabled by
default. To enable in development, set
config.action_view.debug_rjs = true
Support for Rails 4.1 and above
Unfortunately, due to limited manpower and resources, the Rails core team has not been able to confirm if this gem currently works with Rails 4.1 and above. If you have found any problems while upgrading your application, please report them at the issue tracker, or better yet, submit patches by sending a pull request.
In any case, this gem will NOT be officially supported on Rails 5.0 and above.
