Description
Do you think success callbacks
- defined on transitions
- trigger after the state is persisted
is something worth considering and sending a patch for?
Use case is something like
class Order < ActiveRecord::Base
include AASM
aasm do
state :unconfirmed
state :cash_on_delivery
state :paid
event :confirm do
transitions to: :cash_on_delivery,
from: unconfirmed,
success: proc { cash_on_delivery_callbacks },
guard: { payment_type == 'Cash on Delivery' }
transitions to: :paid,
from: :unconfirmed,
success: proc { other_payment_type_callbacks },
guard: { payment_type != 'Cash on Delivery' }
end
end
endSuccess callbacks would perform work specific to the transition path and would have to run only after state transition is successful.
New order of calling would be something like
begin
event before
event guards
transition guards
old_state before_exit
old_state exit
transition after
new_state before_enter
new_state enter
...update state...
transition success # if persist successful
event success
old_state after_exit
new_state after_enter
event after
rescue
event error
end
