Events can't share name with methods in the Kernel module

[smathieu]

I have the following class that defines an event named 'abort'.

class Run < ActiveRecord::Base
  state_machine :initial => :queued do
    event :abort do
      transition any => :aborted
    end
  end
end

When I try to fire the event, I get the following error:

NoMethodError: private method `abort' called for #<Run:0x007f9480936c70>

This is likely because the abort method is defined in the Kernel module or ruby, and thus is available for any object.

I've made a fork of the repo and reproduced the failure in a unit test.

You can probably work around this buy using the low level methods.

YourClass.state_machines[:name_of_machine].events[:abort].transition_for(instance_of_your_class).perform(args)

Probably, but that's an horrible hack :)

That's not a hack, it's just not using the instance helper methods, which are an abstraction over the one mentioned.

Alternatively you can remove/undef the method from your class before initializing the state machine.
