Rails 5 undefined method hide_action

Hey, when I try to run Rails 5 beta app, I get this error:

@mensfeld Thanks very much for bringing this to our attention. There is actually another pull-request (#121) that fixes this. I'll look into getting this fixed asap.

@mattpolito you are welcome. Here's a temporary patch for that issue: http://dev.mensfeld.pl/2015/12/upgrading-to-ruby-on-rails-5-0-from-rails-4-2-application-use-case/

[mattpolito]

This is addressed in v.2.3.3
