How do I activate a workflow transition from a wizard?

wizard workflow transition signal

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

For OpenERP v7 as said:

import netsvc
...
wf_service = netsvc.LocalService('workflow')
wf_service.trg_validate(uid, 'account.invoice', id, 'invoice_cancel', cr)

For Odoo v8 the code change a little

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

#or with the new api
self.pool.get('account.invoice').signal_workflow(cr, uid, account_invoice, 'invoice_open')

#Edit for Update
For Odoo v9 and v10 and latter ...

records = self.env['account.invoice'].browse(ids)
records.signal_workflow('invoice_cancel')

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!

Hi, netsvc module does not import correctly, I get this error: ImportError: No module named netsvc, any idea what happens, thanks

Adnier Rosello

well, i have got imported the module netsvc, but now i have this error: File "/home/usuario/workspace/odoo/addons/mrp_zabyca/mrp_production.py", line 130, in set_justify wf_service.trg_validate(self.env.user,'mrp.production',id,'button_cancel', self.env.cr) File "/home/usuario/workspace/odoo/openerp/workflow/__init__.py", line 85, in trg_validate return WorkflowService.new(cr, uid, res_type, res_id).validate(signal) File "/home/usuario/workspace/odoo/openerp/workflow/service.py", line 37, in new return cls(Session(cr, uid), Record(model_name, record_id)) File "/home/usuario/workspace/odoo/openerp/workflow/helpers.py", line 6, in __init__ assert isinstance(uid, (int, long)) AssertionError

see how to do it in odoo v8 here in my answer

Jos De Graeve

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

@Axel Mendoza,

I haven't karma to comment your answer but if in V8 the code change a little, what about in v10 ?

I need to delete a workflow then create it in V10 but i didn't get uid, cr parameters, any help please ?

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

Axel Mendoza

Please could someone change the accept answer on this thread as seems to be mine the most requested so others in the future could pick it quickly
