V10将One2Many值传递给瞬态模型One2Many（onchange中的TypeError，默认情况下是DataError）

Question

我正在为hr.payroll定制一个模块，用于为工资单注册付款，首先是一个Register Payment向导，该向导随后在验证要打印的支票时将数据传递给account.payment。备注和partner_id之类的所有其他字段均按预期方式通过，但没有在我的one2many字段中填充任何内容，该字段试图从hr.payslip line_ids中提取Name和Amount值。

我的One2Many字段：

pay_line_ids = fields.One2many（'pay.line.ids'，'payline_id'，string ='Paylines'，readonly = False，copy = True）

class PayLineIds(models.Model):
    _name = 'pay.line.ids'
    _description = 'Payslip Payment Lines'

    payline_id = fields.Many2one('account.payment', string='Pay Slip', required=False)
    name = fields.Char(string='Name', required=False)
    amount = fields.Float(digits=dp.get_precision('Payroll'))

我尝试了两种方法。任何帮助表示赞赏。

首先设置onchange

@api.onchange('pay_line_ids')
def _onchange_lines(self):
    context = dict(self._context or {})
    active_ids = context.get('active_ids', [])
    payslip = self.env['hr.payslip'].browse(active_ids)
    ids = []
    for line in payslip.line_ids:
        lines = {'name':line.name,'amount':line.amount}
        ids.append(lines)
    self.pay_line_ids = [(6,0,ids)]

将导致以下错误：

  File "/mnt/extra-addons/hr_payroll_payment/hr_payroll_register_payment.py", line 119, in _onchange_lines
    self.pay_line_ids = [(6,0,ids)]
  File "/usr/lib/python2.7/dist-packages/odoo/fields.py", line 933, in __set__
    value = self.convert_to_cache(value, record)
  File "/usr/lib/python2.7/dist-packages/odoo/fields.py", line 2055, in convert_to_cache
    ids = OrderedSet(command[2])
  File "/usr/lib/python2.7/dist-packages/odoo/tools/misc.py", line 1121, in __init__
    self._map = OrderedDict((elem, None) for elem in elems)
  File "/usr/lib/python2.7/collections.py", line 52, in __init__
    self.__update(*args, **kwds)
  File "/usr/lib/python2.7/_abcoll.py", line 567, in update
    self[key] = value
  File "/usr/lib/python2.7/collections.py", line 58, in __setitem__
    if key not in self:
TypeError: unhashable type: 'dict'

第二个设置默认值。

pay_line_ids = fields.One2many（'pay.line.ids'，'payline_id'，string ='Paylines'，readonly = False，copy = True，默认= _default_line_ids）

@api.model
def _default_line_ids(self):
    context = dict(self._context or {})
    active_ids = context.get('active_ids', [])
    payslip = self.env['hr.payslip'].browse(active_ids)
    res = {}
    for line in payslip.line_ids:
        res = {
            'name': line.name,
            'amount': line.amount,
            }
        return [(6, 0, res)]

将导致以下错误：

DataError: invalid input syntax for integer: "amount"
LINE 2: ...                      WHERE "pay_line_ids".id IN ('amount', ...
                                                             ^

Answer 1

用于传递值的语法不正确。

(6, _, ids) replaces all existing records in the set by the ids list
