StateMachine::InvalidTransition (Cannot transition state via :next from :payment (Reason(s): Нет незавершённых платежей)

[BRZInc]

Hello,

Thanks for development of spree_robokassa gem. It looks excellent. Though I have a small issue with it.

Yesterday I've installed it to my site and still can't make it work for me in the test mode. Whenever I try to proceed with payment I get the following exception: StateMachine::InvalidTransition (Cannot transition state via :next from :payment (Reason(s): Нет незавершённых платежей) (in english exception message says 'No payment found').

This exception occurs when I get to the "http://test.robokassa.ru/ReturnResults.aspx?Culture=ru" page and click on "Перейти" button.

I use spree 2.1.4. I've made a fork of this gem and added a few small changes into it: https://github.com/BRZInc/spree_robokassa.git

Here is my log: I, [2014-01-29T16:45:05.960022 #1095] INFO -- : Completed 200 OK in 1065ms (Views: 775.6ms | ActiveRecord: 43.6ms) I, [2014-01-29T16:45:15.142067 #1090] INFO -- : Started GET "/gateway/robokassa/result?OutSum=2690.0&InvId=724416111&SignatureValue=A08D9FEE8B0972A64D34802D92546F48" $ I, [2014-01-29T16:45:15.151368 #1090] INFO -- : Processing by Spree::Gateway::RobokassaController#result as HTML I, [2014-01-29T16:45:15.151471 #1090] INFO -- : Parameters: {"OutSum"=>"2690.0", "InvId"=>"724416111", "SignatureValue"=>"A08D9FEE8B0972A64D34802D92546F48"} I, [2014-01-29T16:45:15.304705 #1090] INFO -- : Completed 500 Internal Server Error in 153ms F, [2014-01-29T16:45:15.308554 #1090] FATAL -- : StateMachine::InvalidTransition (Cannot transition state via :next from :payment (Reason(s): Нет незавершённых платежей)): state_machine (1.2.0) lib/state_machine/event.rb:252:in block in add_actions' state_machine (1.2.0) lib/state_machine/machine.rb:765:incall' state_machine (1.2.0) lib/state_machine/machine.rb:765:in block (2 levels) in define_helper' /home/spree/jersey_shop/shared/bundle/ruby/1.9.1/bundler/gems/spree_robokassa-1257d39b8ac2/app/controllers/spree/gateway/robokassa_controller.rb:34:inresult' actionpack (4.0.0) lib/action_controller/metal/implicit_render.rb:4:in send_action' actionpack (4.0.0) lib/abstract_controller/base.rb:189:inprocess_action' actionpack (4.0.0) lib/action_controller/metal/rendering.rb:10:in process_action' actionpack (4.0.0) lib/abstract_controller/callbacks.rb:18:inblock in process_action' activesupport (4.0.0) lib/active_support/callbacks.rb:463:in _run__187398052__process_action__callbacks' activesupport (4.0.0) lib/active_support/callbacks.rb:80:inrun_callbacks' actionpack (4.0.0) lib/abstract_controller/callbacks.rb:17:in process_action' actionpack (4.0.0) lib/action_controller/metal/rescue.rb:29:inprocess_action' actionpack (4.0.0) lib/action_controller/metal/instrumentation.rb:31:in block in process_action' activesupport (4.0.0) lib/active_support/notifications.rb:159:inblock in instrument' activesupport (4.0.0) lib/active_support/notifications/instrumenter.rb:20:in instrument' activesupport (4.0.0) lib/active_support/notifications.rb:159:ininstrument' actionpack (4.0.0) lib/action_controller/metal/instrumentation.rb:30:in process_action' actionpack (4.0.0) lib/action_controller/metal/params_wrapper.rb:245:inprocess_action' activerecord (4.0.0) lib/active_record/railties/controller_runtime.rb:18:in process_action' actionpack (4.0.0) lib/abstract_controller/base.rb:136:inprocess' actionpack (4.0.0) lib/abstract_controller/rendering.rb:44:in process' actionpack (4.0.0) lib/action_controller/metal.rb:195:indispatch' actionpack (4.0.0) lib/action_controller/metal/rack_delegation.rb:13:in dispatch' actionpack (4.0.0) lib/action_controller/metal.rb:231:inblock in action' actionpack (4.0.0) lib/action_dispatch/routing/route_set.rb:80:in `call'

From the log I see that Robokassa tries to call back my site by the Return URL, but an exception occurs on my side, when I try to call @order.next!. I've checked by InvId - I have such an order in my list in the Payment state.

Please help! This thing blows my mind for 2 days already. Can't figure out what else to try

it is not ready for current stable spree version. you can try to fix it , and i will merge you pull request.

[BRZInc]

The problem is that I can't figure out myself what goes wrong:(

For some reason @order.next! throws me an error.

Can you please help?

[pronix]

order haven't payments.

[BRZInc]

I've meant that exception occurs on the following line: @order.next! until @order.state == "complete"

[BRZInc]

@artemaminov, sorry for disturbing you, but probably you have some bright ideas about this?

[pronix]

order should have payments for call 'next!' on 'payment' state

(Cannot transition state via :next from :payment (Reason(s): Нет незавершённых платежей) (in english exception message says 'No payment found').

[artemaminov]

@BRZInc, @pronix is absolutely right

[BRZInc]

@pronix, @artemaminov Gentlemen, but what should I do in this case? I've took @artemaminov 's fork, made some minor changes into it. Now can't figure out why it's not working.

Though I haven't tried production mode, but testing mode is not working for me.

[pronix]

@BRZInc try to understand how to working aasm in spree.

[artemaminov]

@BRZInc, excuse me, but my fork is not ready yet

[BRZInc]

@pronix @artemaminov gentlemen, thanks a lot for your comments! Fincally I've used forked fork of @antonfefilov. It looks a bot more stable for me.

Overall thing seems to be working. Though with test robokassa account I get Invalid Signature error. After the code review I've figured out onew thing in robokassa_controller, which I don't understand. It exists in all versions.

In result and success methods valid_signature is checked against different passwords: In def result:

if @order && @gateway && valid_signature?(@gateway.options[:password2])

In def result:

if @order && @gateway && valid_signature?(@gateway.options[:password1]) && @order.complete?

def valid_signature?(key)
    params["SignatureValue"].upcase == Digest::MD5.hexdigest([params["OutSum"], params["InvId"], key ].join(':')).upcase
  end

How could it come?
