I would need to evolve the workflow of a resource a from an on_change
. I use the following syntax :
[...]
Model.draft(records)
[...]
but I got the error message:
psycopg2.InternalError: ERROR: cannot execute UPDATE in a readonly transaction
Is it possible ? is there an example somewhere?

You can not, on_change are readonly by design.
You should consider using a button and updating the requierd values on the transition.
BTW: If you explain us the problem you are trying to solve we may be able to give a better guidance.
