Hello,

I am a French student. I want test mymod, for workflow.

But I have this error :

AttributeError: 'NoneType' object has no attribute '_name'

mymod.py

# -*- coding: utf-8 -*-
from osv import fields, osv

def mymod_new(self, cr, uid, ids):
     self.write(cr, uid, ids, { 'state' : 'new' })
     return True

     self.write(cr, uid, ids, { 'state' : 'assigned' })
     return True

     self.write(cr, uid, ids, { 'state' : 'negotiation' })
     return True

     self.write(cr, uid, ids, { 'state' : 'won' })
     return True

def mymod_lost(self, cr, uid, ids):
     self.write(cr, uid, ids, { 'state' : 'lost' })
     return True

class mymod(osv.osv):
    _name = "mymod.mymod"
    _description = "mymod"
    _columns = { 
    'name' : fields.char("names",),
    'state': fields.selection([
    ('new','New'),
    ('assigned','Assigned'),
    ('negotiation','Negotiation'),
    ('won','Won'),
    ('lost','Lost')], 'Stage', readonly=True),

Hi, your problem it is in the line :

<menuitem name="Boutton" parent="dev_menu_person" id="view_partner_form" action="mymod_form" />

action="mymod_form" must reference in record of type ir.actions.act_window

so add this record :

   <record model="ir.actions.act_window" id="action_mymod_form">
        <field name="name">Workflow</field>
        <field name="res_model">mymod.mymod</field>
        <field name="view_type">form</field>
        <field name="view_mode">form</field>
    </record>   
  <menuitem name="Boutton" parent="dev_menu_person" id="view_partner_form" action="action_mymod_form" />

Thx for your help.

But I have this error : Integrity Error

The operation cannot be completed, probably due to the following: - deletion: you may be trying to delete a record while other records still reference it - creation/update: a mandatory field is not correctly set

[object with reference: res_model - res.model]

In French : Erreur d'intégrité

L'opération n'a pas pu être terminée, probablement à la suite d'une : - suppression : vous avez essayer de supprimer un enregistrement auquel d'autres enregistrements font référence - création/modification : un champ requis n'a pas été correctement rempli

[objet ayant pour référence : res_model - res.model]

But my buttons do not appear :(

Borni DHIFI

many errors in your code. the record form should be type ir.ui.view and not ir.actions.act_window because menuitem name="Boutton" should be reference to record action and not record form.

in your model mymod add defualt state to display first button _defaults = { 'state':'new',}

and others...

How to reference "ir.ui.view"?
