Hi all,

Is the state_machine_history gem the best way to maintain state
history?

Are there any other plugins / gems / techniques to look at?

Maybe even something to keep state history in the same table?

Thanks!

Chris

Hey Chris -

state_machine_history is the closest thing that I'd expect of a
history tracker. There is also a library called state_machine_audits
at http://github.com/isotope11/state_machine_audits.

I don't know of any library that stores the history in the same table.

Best of luck,
Aaron

On the same topic, seems like state_machine_history broke with the
update to 0.10... if anyone knows how to get in touch with the authors

It isn't difficult creating your own state machine history using a states table and a has_many association between the stateful model and the states model.

Care is needed in reading and writing, but I was able to do it by overriding the state and state= methods in my stateful model. It works well.

If you want more details, I'll be happy to share more code.

state_machine_history gem has been good, so far (barring the current
version breakage)

Thanks!
