m getting this error * Import error: no module named viewflow.frontend * yet 
i followed the procedures on how to apply the view flow module what could 
be the problem.


 

Flow.py

 

 

from viewflow import flow,lock

from viewflow.base import this, Flow

from viewflow.contrib import celery

from viewflow.flow.views import CreateProcessView, UpdateProcessView, 
Startview

from viewflow import frontend

from viewflow.site import viewsite

 

 

from .models import HelloWorldProcess

 

 

@frontend.register

class HelloWorldFlow(Flow):

    process_class = HelloWorldProcess

    lock_impl = lock.select_for_update_lock

 

    start = (

        flow.Start

        (CreateProcessView,

        fields=["text"]

        ).Permission(auto_create=True)\

        .Next(this.approve))

 

    approve = (flow.View(UpdateProcessView,fields=["approved"])\

        .Permission(auto_create=True)\

        .Next(this.check_approve)

    )

 

    check_approve = (

        flow.If(lambda activation: activation.process.approved)\

        .Then(this.send)\

        .Else(this.end)

    )

 

    send = (celery.Job(tasks.send_hello_world_request)\

        .Next(this.end)

    )

 

    end = flow.End()

 

    viewsite.register(HelloWorldFlow)

 

    #def send_question_app_request(self, activation):

        #print(activation.process.text)
