strange StateMachine behaviour

[ErkA]

hello I've strange problem with state machine

in my model

state_machine :user_state, :initial => :unconfirmed do
state :unconfirmed, :value => 0
state :confirmed, :value => 1
state :trusted, :value => 2

event :verify do
transition :unconfirmed => :confirmed
end

event :trust do
transition [ :unconfirmed, :confirmed] => :trusted
end
end
-----------

x ==> #<Price id: 88, user_id: 1, station_id: 13157,
session_id: "201924b30b53bd38250d396c252b2847", user_type: 2, price:
#<BigDecimal:9f0bdc0,'0.34E2',4(8)>, user_state: 0, created_at:
"2009-12-10 06:22:06", updated_at: "2009-12-10 07:46:33", ip:
"10.10.10.1">
-----------

x.user_state_transitions
==> [#<StateMachine::Transition attribute=:user_state
event=:verify from=0 from_name=:unconfirmed to=1 to_name=:confirmed>,
#<StateMachine::Transition attribute=:user_state event=:trust from=0
from_name=:unconfirmed to=2 to_name=:trusted>]
-----------
events.valid_for(x)
==> [#<StateMachine::Event name=:verify transitions=[:unconfirmed
=> :confirmed]>, #<StateMachine::Event name=:trust transitions=
[[:unconfirmed, :confirmed] => :trusted]>]

-------- and here we go:
x.verify!
StateMachine::InvalidTransition: Cannot transition user_state
via :verify from :unconfirmed

x.trust!
StateMachine::InvalidTransition: Cannot transition user_state
via :trust from :unconfirmed

on log Im getting only:

SQL (0.0ms) BEGIN
SQL (1.8ms) ROLLBACK

but if I use
x.verify false
==> true

what Im doing wrong or where is the problem?




best regards

No idea. But you haven't said what this StateMachine class is or where
you got it from.

If it's a Rails plugin, you'd be better off asking on a Rails mailing
list. Better still, see if this StateMachine has its own mailing list.

I second what Brian said. What -is- this?
Also, you're not actually using :user_state anywhere. What good is it?
