Upgrade to Rails 4?

[joevandyk]

Any chance this gem could be compatible with Rails 4?

[krancour]

Another github user named @peterbeers forked this and made it Rails 4 compatible. It works great. But neither this nor peterbeer's is Rails 4.1 compatible. I dug down into this and try as I might, I couldn't get it to work with Rails 4.1. If someone who understands validations (and the callbacks used internally by validations) better than me, I'd be very interested in a Rails 4.1-compatible version of this.

This fixed the issue for us using Rails 4.2.4.

I am using Rails 4.2.4 but I am still getting the following error:

2.2.3 :002 > game.valid?
NoMethodError: undefined method `validate' for #<ActiveSupport::Callbacks::Callback:0x007f9ae41149b0>

Any ideas?
