Question

Dies ist mein Python-Code. welches hr.employee, res.partner und sale.order erbt.

from openerp.osv import fields, osv 

#Inheriting the hr.employee object

    _inherit = "hr.employee" 

    _columns = { 
       'customer_ids': fields.many2many('res.partner', 'lead_employee_rel', 'emp_id', 'partner_id', 'Customers'),

       } 

#Inheriting the res.partner object

das ist mein XML-Code

      </field> 
     </record> 
    </data> 
</openerp> 

während OnChanging die customer_id, die Seite müssen die Mitarbeiter Details mit nur zwei Felder (Name des Mitarbeiters und Mitarbeiterbewertung) in der Baumansicht laden. Die Felder werden zum ersten Mal richtig geladen, aber während ich die Kundennummer ändere, werden die Baumansichtsfelder nicht aktualisiert.

Answer 1

Versuchen Sie, die "magischen Zahlen" unter def write in openerp.osv.orm.BaseModel (V7) oder openerp.models.Model (V8 +) dokumentiert zu verwenden:

def on_change_partner_id(self, ...): 
    # ... 
    emp_tuple_list=[(5,)] # without (5,) it won't delete all old data 
    for emp in part.employee_ids: 
     emp_tuple_list.append((4, emp.id)) 
    val.update({'employee_ids': emp_tuple_list}) 
    # ...
