Hi,

I have data with a many2many relation between 2 models. Simplified model is :

Class property(orm.Model):

        _name = 'property'

        _columns = {

                'value_ids': fields.many2many(

                        'value', 'property_value', 'property_id', 'value_id', _('Values'))

        }

Class value(orm.Model):

        _name = 'value'

        _columns = {

                'property_ids': fields.many2many(

                        'property', 'property_value', 'value_id', 'property_id', _('Properties')),

                'field1': fields.char(_('Field 1')),

                'field2': fields.char(_('Field 2'))

        }

class dummy(orm.Model):

       _name = 'dummy'

       _columns = {

            'case_study_ids': fields.one2many(
                  'property', 'dummy_id', string=_('Properties'))

      }

Until here, everything works fine. Now, on my dummy model form view I have a button who launch a wizard who makes some process over values for a specific property (id passed in context). This wizard first shows values associated to property and allows modifications on them. Then, the internal process is done.

class property_process_wizard(orm.TransientModel):
        _name = 'property.process.wizard'
    
        def get_value_ids(self, cr, uid, ids, field_name, arg, context=None):
                property_id = context.get('property_id', False)
                if not property_id:
                        return dict([(id, []) for id in ids])

                value_obj = self.pool.get('value')
                value_ids = value_obj.search(cr, uid, vals = [('property_id', '=', property_id)])
                return dict([(id, value_ids) for id in ids])

 

        _columns = {

                'value_ids': fields.function(get_value_ids, type='one2many',
                                                                                                   obj='value'),

        }

Here is my problem. The field function is not computed when the wizard is launched. Is there a way to force field computation on wizard launching?

Best regards,
