Odoo 8 KeyError auf benutzerdefiniertes Modul auf "Upgrade-Modul"

Question

Ich habe eine verwandte Feld-Setup und funktioniert gut, wenn das Feld zu FormView über GUI im Entwicklermodus hinzugefügt wird. Wenn ich jedoch die Felder dem benutzerdefinierten Modul hinzugefügt habe und versucht habe, ein Upgrade durchzuführen, bricht es mit KeyError auf x_work_order_num. Was vermisse ich?

Einige andere Hinweise:

• odoo-Server nach Änderungen neu gestartet
• Felder in den Einstellungen existieren .py> Datenbankstruktur> Modelle und Felder
• x_rel_order und x_ext_num Hinzufügen über Bearbeiten Formview Formuaransicht (Entwicklermodus) funktioniert, aber Upgrade über lokale Module löst den obigen Fehler aus.
• Fehler tritt auf, bevor "onchange" -Methode implementiert wurde.

KeyError: 'x_work_order_num' 

Answer 1

Nicht gerade etwas, das einige suchen können, aber in meinem Fall, was ich gebraucht habe gelöst wurde durch das Ersetzen Definition von

x_ext_num = fields.Char(related='x_rel_order.x_work_order_num', string ="External Number") 

mit

x_ext_num = fields.Char(string='External Number', compute='_compute_x_ext_num') 

Ich brauche die entsprechende Option nicht und band einen ON_CHANGE im XML ein Verfahren:

@api.multi 
def onchange_x_rel_order(self, order_id, context=None): 
    ext_num = '' 

    if(order_id): 
     p = self.env['sale.order'].browse(order_id) 
     ext_num = p.x_work_order_num 

    res = { 
      'value': { 
       'x_ext_num': ext_num 
      } 
    } 

    return res 


def _compute_x_ext_num(self): 
    for record in self: 
      p = self.env['sale.order'].browse(record.x_rel_order.id) 
      record.x_ext_num = p.x_work_order_num
