How do I activate a workflow transition from a wizard?

By

I've set up a wizard in OpenERP 7.0 that is updating fields correctly and all is working fine. Now I would like that, after submitting and updating the information on my object, the wizard would send a signal to the workflow of the object it acted uppon, to check if there is any transition to be taken.

How should I do that?

Do I have to directly call the workflow action from inside the def save_info() (see code below)? (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!

My wizard python 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})

          #self.pool.get('generic.request').req_reformulate_request(cr, uid, context['active_id'], context)
        return {
                'type': 'ir.actions.act_window_close',
         }
ref_generic_request()

And this is the XML that defines wizard's view:

<?xml version="1.0" encoding="utf-8"?>
<openerp>
    <data>
        <record id="view_reformulate_generic_request_wizard" model="ir.ui.view">
            <field name="name">reformulate_generic_request_wizard.form</field>
            <field name="model">ref.generic.request</field>
            <field name="type">form</field>
            <field name="arch" type="xml">
                <form string="Insert reformulation info" version="7.0">
                    <group >
                        <separator string="Please insert instruction for the reformulation of this request" colspan="2"/>
                        <field name="reformulation_info" string="Reformulation info"/>
                        <newline/>
                    </group>
                    <div style="text-align:right">
                        <button  icon="gtk-cancel" special="cancel" string="Cancel"/>
                        <button  icon="gtk-ok" name="save_info" string="Send to reformulation" type="object" />
                    </div>
               </form>
            </field>
        </record>
        <record id="action_reformulate_generic_request" model="ir.actions.act_window">
            <field name="name">Reformulate Request</field>
            <field name="type">ir.actions.act_window</field>
            <field name="res_model">ref.generic.request</field>
            <field name="view_type">form</field>
            <field name="view_mode">form</field>
            <field name="view_id" ref="view_reformulate_generic_request_wizard"/>
            <field name="target">new</field>
        </record>
        <act_window id="action_reformulate_generic_request"
                name="Reformulate Request"
                res_model="ref.generic.request"
                view_mode="form"
                target="new"
        />
    </data>
</openerp>

I have a workflow (I'll show here only the part that is relevant for this question):

<?xml version="1.0"?>
<openerp>
    <data>
        <record model="workflow" id="wkf_request">
            <field name="name">request.wkf</field>
            <field name="osv">generic.request</field>
            <field name="on_create">True</field>
        </record>
    (...)
        <record model="workflow.activity" id="act_confirm">
            <field name="wkf_id" ref="wkf_request" />
            <field name="name">request_confirmed</field>
            <field name="kind">function</field>
            <field name="action">confirm_request()</field>
        </record>
        <record model="workflow.activity" id="act_req_reformulate">
            <field name="wkf_id" ref="wkf_request" />
            <field name="name">request_reformulation</field>
            <field name="kind">function</field>
            <field name="action">req_reformulate_request()</field>
        </record>
    (...)
        <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>
    (...)
    </data>
</openerp>

And after the wizard updates info in my generic.request object I would like it to signal a function that and is actually called from the workflow the make the transition:

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

Hello Luis,

In order to do your thing with worflows, the code below should do the trick:

 

import netsvc

request_id = context['active_id']

if request_id:

wf_service = netsvc.LocalService('workflow')

wf_service.trg_validate(uid,'generic.request',request_id,'req_reformulate_request',cr)

 

Regards,

Jos

For OpenERP v7 as  said:

import netsvc
...
wf_service = netsvc.LocalService('workflow')
wf_service.trg_validate

For Odoo v8 the code change a little

from openerp import workflow
...
workflow.trg_validate(uid, 'account.invoice', id, 'invoice_cancel', cr)

Thanks a lot! I'll try it out and will give you feedback right away!. This code should be included in my wizard.py, right?

Jos De Graeve,YOU are the best! It worked! Thanks a lot.

For future reference, I'll leave here the modification on my py code, in order to make it work.

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()

Once again, many, many thanks!
