Warum bekomme ich den Fehler: 'int' Objekt hat kein Attribut 'create'?

Question

Code:

@api.multi 
    def open_second_class(self): 
     ac = self.env['ir.model.data'].xmlid_to_res_id('account.invoice_form', raise_if_not_found=True) 
     write_obj = ac.create({'partner_id': self.name_id}) 
     accountant = False 
     for o in self: 
      accountant = o.id 
     result = { 
      'name': '2nd class', 
      'view_type': 'form', 
      'res_model': 'account.invoice', 
      'res_id': write_obj.id, 
      'view_id': False, 
      'context': {'default_id_tbl1': accountant}, 
      'type': 'ir.actions.act_window', 
      'view_mode': 'form', 
      'target': 'new', 
      'domain': '[]' 
     } 
     return result 

Fehler:

Answer 1

Verwenden self.env.ref('external_id') anstelle der xmlid_to_res_id Methode. Aber ich denke, was wollen Sie so etwas wie dies zu tun ist:

@api.multi 
def open_second_class(self): 
    self.ensure_one() 
    ac = self.env.ref('account.invoice_form') 
    invoice = self.env['account.invoice'].create({ 
     'partner_id': self.name_id.id 
    }) 

    return { 
     'name': '2nd class', 
     'type': 'ir.actions.act_window', 
     'res_model': 'account.invoice', 
     'res_id': invoice.id, 
     'view_type': 'form', 
     'view_mode': 'form', 
     'target': 'new', 
     'context': {'default_id_tbl1': self.env.id }, 
    }
