django-workflow-activity 1.2.0

Manage all events on workflows

Install

Install the package via pypi:

pip install django-workflow-activity

Add the installed application in the django settings file:

INSTALLED_APPS = (
    ...
    'workflow_activity'
)

Migrate the database:

python manage.py migrate

Usage

To create workflows and permissions, see the following documentations:

• https://pythonhosted.org/django-workflows

• https://pythonhosted.org/django-permissions

To use workflow activity methods on a class :

from workflow_activity.models import WorkflowManagedInstance

class MyClass(WorkflowManagedInstance):
    ...

To add a workflow to an object:

myobj = MyClass()
myobj.set_workflow('My workflow')

Now, you can use methods on your object like:

myobj.last_state()
myobj.last_transition()
myobj.last_actor()
myobj.last_action()
myobj.allowed_transitions(request.user)
myobj.is_editable_by(request.user, permission='edit')
myobj.state()
myobj.change_state(transition, request.user)
...

And managers like:

MyClass.objects.filter()
MyClass.pending.filter()
MyClass.ended.filter()
...
