Question

如何从hr_payslip类扩展onchange_employee_id方法，我尝试过这段代码：

import openerp
from openerp.osv import fields, osv
from openerp import api, fields, models, _, SUPERUSER_ID

class hr_payslip(models.Model):
    _inherit = 'hr.payslip'


    @api.onchange('employee_id')
    def onchange_employee_id(self, date_from, date_to, employee_id=False, contract_id=False):
      *#my logic here* 
       return {}

我得到了这样的错误：

    Traceback (most recent call last):
  File "C:\Program Files (x86)\Odoo 8.0\server\.\openerp\http.py", line 544, in _handle_exception

和iam使用odoo v8，谢谢

Answer 1

你不需要使用cr，uid，context作为函数的参数。在新的odoo api方法中，你可以使用装饰器来调用onchange。因此，您应该删除 @ api.model 或使用 @ api.onchange（'employee_id'）。如果你正在使用装饰器，那么你应该删除不需要的 cr，uid，id，context ，我们可以访问 self 这些形式。

如果你需要扩展onchange方法，一个选项是在继承模型'hr.payslip'中重新定义函数并定义一个函数，如下所示

@api.onchange('employee_id')
def onchange_employee_id(self):#gave extra arguments if any
      *logic*
      return {}

Answer 2

您必须从原始功能

复制剪切def线

def onchange_employee_id(self, cr, uid, ids, date_from, date_to, employee_id=False, contract_id=False, context=None):
        res=super(hr_payslip, self).onchange_employee_id(self, cr, uid, ids, date_from, date_to, employee_id=False, contract_id=False, context=None)

        # Add your code here
        return res

从hr_payslip类扩展onchange_employee_id方法
