Django Viewflow - How do apply the same transition for multiple tasks

Question

With viewflow, My usecase is this: A user is assigned multiple tasks. He wants to select some of the task and apply the same transition(Approve/Reject) to them. How can he do this?

Answer 1

Nothing specific. Just to activate and complete activation per-task. For safety reasons, you need to pre .select_for_update all included processes.

Process.objects.filter(...).select_for_update()
for task in _list_of_tasks_:
   activation = task.activate()
   activation.prepare()
   # do something
   # activation.process.approved = False
   # activation.process.save()
   activation.done()
