Inverted "not_" AR scopes

[h0jeZvgoxFepBQ2C]

Hi,

It would be nice to have also inverted automatic ActiveRecord scopes, like f.e. for a Sms-Model:

state :delivered

=> SmsMessage.delivered

It would be nice if we would add the "not_" scopes as well:

=> SmsMessage.not_delivered

# like SmsMessage.where("aasm_state <> (?)", STATE_DELIVERED)

If you like, I can open a PR? Just tell me if you would accept such a change or if you have any thoughts about this?

Another option is to allow a boolean argument, inverted that defaults to false. Then you would use SmsMessage.delivered(false). I prefer this when you have filters where the user may turn it on or off, because then you only have to change the argument instead of using #send to change the method name.

I came here to propose something similar, but I was thinking on automatic scopes for events, something like Model.may_event to get all models that could transition to an event. Is it something for another issue? Not sure I can provide a PR in the short term...

Edit: change verb :P
