A django app enabling Django models to use xworkflows.
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() [TransitionLog(MyModel: new -> old at 2012-04-14T12:10:00+0200)]
