We currently do something similar (time-based workflow transition)
Our setup is:
* python script that searches for all content in particular workflow
state and performs the correct transition
* cron job to automatically call the script at particular intervals
In your case you could search for all content that is 'expired' and
perform that workflow transition 'submit'.
Here's a partial example of code that we use:
#
# Apply a workflow transition after a period of time
#
from DateTime import DateTime
import time
def applyTransition(self, transition, time_offset):
pc = self.portal_catalog
pw = self.portal_workflow
t0 = DateTime(time.time() - time_offset * 3600)
pending = 0
promoted = 0
#
# Grab all of the offers that are only visible to premium members
#
for obrain in pc.queryCatalog({'portal_type':"OfferFolder",
'review_state':"respondable_premium"}):
o = obrain.getObject()
last_transition = o.workflow_history['offer_folder_workflow'][-1]
t1 = last_transition.get('time')
pending += 1
#
# Check to see if this offer has passed the blackout period
#
pending_objs = {}
if t1 < t0:
promoted += 1
#
# TODO: currently it silently ignores objects who's
transition does not exist
#
for t in pw.getTransitionsFor(o):
if t['id'] == transition:
pw.doActionFor(o, transition)
pending_objs[pending] = o.absolute_url()

Hi all,
I want to set up a workflow that automatically submits content for
review (by changing its state) when it reaches its expiration date.
I'm using Plone 2.1.1
Any ideas?
