Activate a workflow transition from wizard in OpenERP 7.0 - workflow

Question

I've set up a wizard in OpenERP 7.0 that is updating fields correctly and all is working fine. But I would like to send a signal to the workflow from that wizard after user submits information to check if there is any transition to be taken.
My wizard code is the following:
from openerp.osv import osv
from openerp.osv import fields
from openerp.tools.translate import _
class ref_generic_request(osv.osv_memory):
_name='ref.generic.request'
_columns = {
'reformulation_info': fields.text('Reformulation instructions', help='Instructions for the requestor justification the reformulation needs'),
}
def save_info(self, cr, uid, ids, context=None):
if 'active_id' in context:
info=self.browse(cr,uid,ids)[0].reformulation_info
self.pool.get('generic.request').write(cr,uid,context['active_id'],{'reformulation_info' : info, 'needs_reformulation': 1})
return {
'type': 'ir.actions.act_window_close',
}
ref_generic_request()
And in this particular case I would like to signal this function in my generic.request object:
def req_reformulate_request(self, cr, uid, ids, context=None):
req = self.browse(cr, uid, ids, context=context)
goto = req[0].state
if goto:
self.write(cr, uid, ids, {'goto': goto, 'state': 'req_reformulation', 'needs_reformulation': True} )
else:
self.write(cr, uid, ids, {'state': 'req_reformulation', 'needs_reformulation': True})
self.insert_trace(cr, uid, ids, context)
return True
How should I do that?
Do I have to call the function inside the def save_info()? (I've tried this call self.pool.get('generic.request').req_reformulate_request(cr, uid, context['active_id'], context) but it throws so many errors, that I quickly gave up this approach)
Do I have to return something like 'signal': 'generic.request.req_reformulate_request' ?
Since I didn't find any information on this, I'm completely lost here, so any help would be very appreciated!
Thanks!

The transition I want to trigger in this particular case is the one with id="request_t2"
<record model="workflow.transition" id="request_t2">
<field name="act_from" ref="act_submit" />
<field name="act_to" ref="act_req_reformulate" />
<field name="signal">req_reformulate_request</field>
</record>
And here is a screenshot of the workflow, the highlighted transition is the one I want to trigger.

Answer 1

I finaly found the answer. I'll leave here the modified python code that made it!
from openerp.osv import osv
from openerp.osv import fields
from openerp.tools.translate import _
import netsvc
class ref_generic_request(osv.osv_memory):
_name='ref.generic.request'
_columns = {
'reformulation_info': fields.text('Reformulation instructions', help='Instructions for the requestor justification the reformulation needs'),
}
def save_info(self, cr, uid, ids, context=None):
if 'active_id' in context:
info=self.browse(cr,uid,ids)[0].reformulation_info
self.pool.get('generic.request').write(cr,uid,context['active_id'],{'reformulation_info' : info, 'needs_reformulation': 1})
wf_service = netsvc.LocalService('workflow')
wf_service.trg_validate(uid,'generic.request',context['active_id'],'req_reformulate_request',cr)
return {
'type': 'ir.actions.act_window_close',
}
ref_generic_request()
So, resuming, I had to add 3 lines to my code:
import netsvc
And, after saving my info, invoked the workflow with these two:
wf_service = netsvc.LocalService('workflow')
wf_service.trg_validate(uid,'generic.request',context['active_id'],'req_reformulate_request',cr)
Hope this will help someone! :)

On odoo8 use signal_workflow method.
#api.multi
def confirm_multi_payslips(self):
for payslip in self:
payslip.signal_workflow('hr_verify_sheet')
