Rails equivalent to php die()?

Question

Is there an equivalent in Rails to PHP's die()?

I have a case where it would make my controller code a little cleaner to set it up in a way that would sometimes call render twice, unless there is a die() that is.

@Andrei S, That would work but I have several actions that use a common resond method, and I just want to call "die" once in the common respond method. — tybro0103, May 26 '11 at 19:52

abort("Message goes here")

A better answer is `render :text => "Message goes here"` – skcin7 Nov 09 '12 at 07:16

I won't pretend to be a Ruby expert, but according to [this article](http://guides.rubyonrails.org/layouts_and_rendering.html) it seems that `render` is inappropriate as an equivalent to PHP's `die()` because execution continues after `render` is called. – George Cummins Nov 10 '12 at 09:00

A direct mapping of PHP's die() in Ruby would be Kernel::exit()

Er, it really isn't. `Kernel::exit()` raises a SystemExit exception, an exception which can be caught and ignored. While PHP's `die()` does permit destructors to run, this is a different circumstance and calling it a direct mapping is wholly inaccurate. – Winfield Trail Nov 07 '14 at 19:05
