How can I use callback to check before status transition? #69

Open luoxi001713 opened 3 years ago

Scenario: Status A - > status B, I want to check if a field is valid before transition.

I know there is a before_EVENT, but I don't know how to control don't let the status from A to B in this function.

Thanks

I saw that there is a Cancel() method in event object you can call it in callbacks
