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)



this is my flow.py

[chris rose]

did you add 'viewflow.frontend' to installed_apps?

[Михаил Подгурский]

It looks that you are using an outdated version of the viewflow.

viewflow.frontend was added to the open-source version since 0.12+

Please consider upgrade to the latest 0.12.2

You can check out the viewflow cookbook helloword sample, and get it
running with few commands.

https://github.com/viewflow/cookbook/tree/master/helloworld

$ virtualenv env --python=python3.4
$ env/bin/pip install requirements.txt
$ env/bin/python manage.py migrate
$ env/bin/python manage.py createsuperuser
$ env/bin/python manage.py runserver
