Assign user to tasks automatically (Viewflow, Django)

I'm using Viewflow/Django and trying to assign tasks created by dynamic nodes.

I'm using the same nodes.py in customnode.

However, I need to automatically assign each new task based on information in the MOCTask model (the assignee).

But tasks don't allow an Assign with anything other than a specific user object and I don't have access to the MOCTask objects (they are related by foreign key to MOC, which is related by foreign key to MOCProcess, the flow itself).

My code I was trying (flows.py):

...
split_on_task_assignment = (
  DynamicSplit(lambda p: MOCTask.objects.filter(MOC=p.MOC).count())
  .IfNone(this.end)
  .Next(this.task_completion)
)

task_completion = (
  flow.View(views.TaskCompletion)
  .Permission('MOC.is_MOC_actor')
  .Assign(this.assign_actors)
  .Next(this.join_on_task_completion)
)
...
def assign_actors(self, activation):
  task = MOCTask.objects.filter(MOC=activation.process.MOC, assigned=False).first()
  task.assigned = True
  task.save()
  return User.objects.filter(email=task.assignee).first()

However, I can't put a this reference in the assign block, so I'm not sure how to proceed.

Any ideas?

Solution

  • Users can be assigned inside DynamicSplitActivation when subsequent tasks are created

    def activate_next(self): if self._split_count: token_source = Token.split_token_source( self.task.token, self.task.pk) for _ in range(self._split_count): activation = self.flow_task._next.activate( prev_activation=self, token=next(token_source)) activation.activate(..a user..)
