📞 Disable ActiveRecord callbacks in Rails for great justice!

Hold Please

Because ActiveRecord callbacks are a bad idea. They're way too easy to misuse and should probably be removed from Rails altogether. But, as some Rails core team members in favor of the removal have pointed out, that will probably never happen.

But that's no reason not to protect yourself and your loved ones.

class User < ActiveRecord::Base

  before_create do
    # Bad stuff
  end

end

>> User.create!
HoldPlease::NoCallbacks: You really shouldn't use ActiveRecord callbacks

Installation

Add the gem to your Gemfile.

gem "hold_please"

Usage

You don't have to do anything—just don't use ActiveRecord callbacks. If someone does, an exception will be raised letting them know they've done a bad thing. Callbacks used from within gems will continue to work as normal—an exception will only be raised if a callback is used from inside the app.

It should work on Rails versions 3.0.0 and up.

Credits

Lots of love to Gary Bernhardt and his gem Do Not Want for giving me the idea.

Also infinite thanks to Avand, as always, for brainstorming the perfect name with me and myriad other things.
