Scopes are not being created in activerecord 4.1.9 from a rails engine

@seuros this is a show stopper for me. I'm happy to dig in and fix it but need to be pointed in the right direction. Perhaps a usage error, or documentation needs updated?

I've traced it back further to Integrations. @integrations is an empty array so I'm assuming that I've misconfigured or this module is not registering itself. #register is never called.

[seuros]

Thank you for your input.

#register is in fact used in the integrations, for example : https://github.com/state-machines/state_machines-activerecord/blob/master/lib/state_machines/integrations/active_record.rb#L562

@seuros Found it! Simple problem but I think the readme needs updated:

require 'state_machines'
require 'state_machines-activerecord'

I didn't require it anywhere and expected auto-detection.

[seuros]

Bundler should require them by default.
Else you can require just 'state_machines-activerecord'

[rosskevin]

This may be due to the fact that these models are in a rails Engine.

[seuros]

If state_machines-activerecord is part of your Gemfile, it should work.

[rosskevin]

They are in the gemspec:

  s.add_dependency 'state_machines'
  s.add_dependency 'state_machines-activerecord

But still had to explicitly require them. Perhaps I'm missing a setting for the engine/gem?

[seuros]

I'm facing this exact issue in one of my project (with another gem), maybe it a bug in rails.

PS, you don't need to add state_machines as dependency too, state_machines-activerecord depend on state_machines-activemodel and state_machines.

[rosskevin]

Got it, thank you for the quick assistance.
