Validation with Mongoid 4.0.0-alpha2

[pasitolonen]

My environment

• Ruby: 2.0.0-p353
• Rails: 4.0.2
• Mongoid: 4.0.0-alpha2
• state_machine: the latest

class Foo
   include Mongoid::Document
   field :name
   validates_length_of :name, minimum: 4
end

state_machine, :initial => :start do
event :go do
   transition :start => :end
   end
end

I just wrote a quick example, not copied the actual code so typos may apply, but the problem is as follows. I get a warning:

Instance method "validated?" is already defined in Mongoid::Validatable, use generic helper instead or set StateMachine::Machine.ignore_method_conflicts = true.

All the validations return false no matter if I set them ignore_method_conficts or not. Without state_machine, validations work as expected. Any ideas with this?

Looks like state machine does not support mongoid. As the warning says, Mongoid::Validatable also injects #validated? method on model scope.
