Initial transition not created/callbacks not fired unless `state_machine` is touched

[mikebaldry]

The documentation suggests implementing like:

def state_machine
  @state_machine ||= OrderStateMachine.new(self, transition_class: OrderTransition,
                                                 association_name: :transitions,
                                                 initial_transition: true)
end

the initial transition is created and the callbacks then fired from this initializer, so if the state_machine isn't called after create of a model, this doesn't fire.

I'm not exactly sure of the scenarios state_machine isn't touched, if something happens internally with Statesman but not always or if it mostly happens that our code touches it in most cases, but we've had sporadic issues that has led me to add

after_create { state_machine }

to the models using Statesman, which appears to fix.

Should we need to do this, if so, could it be added to the documentation, if not, any ideas where we're going wrong?

Many thanks!

I'm also facing this issue but the after_create solution isn't working for me, at least not in a test environment. Is this still what you're doing @mikebaldry or did you come up with anything else?

Scratch that, I am facing the issue still, but that fix does work for me. Turns out I'd installed the gem just before the readme got updated, and so I'd installed using ~> 12.0.0 instead of ~>13.0.0 which introduced the initial_transition method itself.

Updating to 13.0.0 now allows me to create that initial transition, provided I manually initialise the state machine after create.

TL;DR is yes, this is an issue.
