Use XWorkflows along with Django models.
Django-XWorkflows allow to bind a Django model to a workflow, with a few extra features:
- Auto-save after transitions
- Log each action into the database
Define a workflow and add it to a model:
from django import models
from django_xworkflows import models as xwf_models
class MyWorkflow(xwf_models.Workflow):
states = (
('new', _(u"New")),
('old', _(u"Old")),
)
transitions = (
('get_old', 'new', 'old'),
)
initial_state = 'new'
class MyModel(xwf_models.WorkflowEnabled, models.Model):
state = xwf_models.StateField(MyWorkflow)Use the workflow:
>>> obj = MyModel()
>>> obj.state # Defaults to the initial_state
State('new')
>>> # Perform a transition
>>> obj.get_old()
>>> obj.state
State('old')
>>> # Object was saved to the database
>>> obj.pk
1
>>> # Logs were saved to the database
>>> xwf_models.TransitionLog.objects.all()
