Persisting additional object information

[bpleao]

Hi, I'm creating my state machine class in 'inheritance mode'. I have some additional properties specific of my class that I'd like to persist and I'd like to leverage the state persistence to do this for simplicity. What would be the proper way of doing this? Thanks.

simplest way would be to create an extra field in your backend of choice (say for example postgres) that stores that data. the way to store the data would be by extending multiple classes to allow that data to be passed to the statemachine classes and the persistence adapter. classes that need to be subclassed: State, Builder, PersistenceAdapter, factory and possibly some others.
The statemachine package allows for use cases like this, so once you identify the correct classes it's fairly easy to implement. work from the existing examples and override only specific methods and you're good to go.
OTOH: I think that the data should be stored via the domain object, which might be much easier to do since you actually have acces to that domain object and will probably use it in your command and rule classes.
