How to run transition about python-statemachine

[galhyt]

Hi @fgmacedo,

But does it calling on_transition (on_event) function as it used to in 0.9.0?

[galhyt]

Ok, I managed with this problem.
I had a decorator to each event's method so I just removed it and moved the logic else where.

Hi @galhyt , it should work the same.

The main difference is that I've made explicit the difference between Event and Transition. An event is the name of the trigger bound to one or more transitions, and transition is any arc that connect two states.

Taking your example:

transition = source.to(target)

• transition is the event name.
• source.to(target) is the transition.

If your system is more event-oriented, you can use the sm.send(<event_name>):

sm.send("transition")

Or if you want to call the event in an imperative-style programming, you can still call the event as a method:

sm.transition()

Please see https://python-statemachine.readthedocs.io/en/latest/transitions.html for a more complete explanation.

Best regards!

Yes. Are you getting an error? Or an action not being called?

[galhyt]

The function on_transition is not being called

[fgmacedo]

The function on_transition is not being called

Can you please copy-paste or write a complete example that reproduces the error that I can run locally?

We have automated tests to test this callback, so maybe is something easy like a typo that a fresh look on the code can spot.

Ok I will,
Tnx
