I want to run my process entirely by code. I've managed to start a process but a I can't run the next part of the process. I tried using the "flow.Function" and calling my desired function but i't says
'Function {} should be called with task instance', 'execute'"
and the documentation on this subject is'nt very clear.
flows.py
@flow.flow_start_func
def create_flow(activation, campos_proceso, **kwargs):
activation.process.asignador = campos_proceso['asignador']
activation.process.ejecutor = campos_proceso['ejecutor']
activation.process.tipo_de_flujo = campos_proceso['tipo_de_flujo']
activation.process.estado_del_entregable = campos_proceso[
'estado_del_entregable']
activation.process.save()
activation.prepare()
activation.done()
return activation
@flow.flow_func
def exec_flow(activation, process_fields, **kwargs):
activation.process.revisor = process_fields['revisor']
activation.process.save()
activation.prepare()
activation.done()
return activation
@frontend.register
class Delivery_flow(Flow):
process_class = DeliveryProcess
start = flow.StartFunction(create_flow).Next(this.execute)
execute = flow.Function(exec_flow).Next(this.end)
end = flow.End()
views.py
def Execute(request): #campos_ejecucion, request):
campos_ejecucion = {
'ejecutor':request.user,
'revisor':request.user,
'observaciones_ejecutor':'Este es un puente magico',
'url_ejecucion':'https://www.youtube.com/watch?v=G-yNGb0Q91Y',
}
campos_proceso = {
'revisor':campos_ejecucion['revisor']
}
flows.Delivery_flow.execute.run()
Entregable.objects.crear_entregable()
return render(request, "Flujo/landing.html")
Generally, running "entirely by code" is the antipattern and should be avoided. Flow class is the set of views bound with URLs, so it's like class-based URL config, you don't need to have one more addition separate view and URL entry.
For custom views, you can take a look at the cookbook sample - https://github.com/viewflow/cookbook/blob/master/custom_views/demo/bloodtest/views.py
As for the actual question, you have missed task_loader. Function node should figure out what task is actually executed. You can do it on the flow layer (with task_loader) or directly get the Task model instance and pass it as the function parameter - http://docs.viewflow.io/viewflow_flow_nodes.html#viewflow.flow.Function
