Python 在odoo13中创建多个记录失败，但在odoo12中通过

我有一个函数，可以将多个奖金分配给员工合同

我的特殊问题是，当我调用此函数时，它会抛出错误，

Expected singleton未能解压缩多个记录…

contract\u id

am using是一个与模型hr.contract相关的多个字段

我理解单例错误的原因，但是我对每个create调用都使用for循环，所以我不知道我的错误在哪里

  def action_allocate_bonus(self):
        for rec in self.contract_ids:
            vals = {
                'contract_id': rec.id,
                'cash_allowance_id': self.cash_allowance_id.id,
                'computation': 'fixed',
                'fixed': rec.allowance_amount,
            }
            self.env['ke.cash_allowances'].sudo().create(vals)

这是实际的日志错误：

似乎是“self”导致了错误，它是一组多条记录，但被称为一条记录。 更具体地说，在

compute\u declutation

的第一行中，它已经遇到了一个问题，即它不知道

computement

字段应该为两个不同的字段返回什么。 我认为您可能希望将整个方法放在for循环中，然后使用记录而不是self。 像这样：

@api.dependens（'计算'，'固定'）
def计算扣除额（自）：
请自行记录：
如果record.computation=='fixed'：
record.amount=record.fixed
....

如果您使用的是odoo12，请在上添加@api.multi decoratormethod@AdamStrauss，我使用的是ODOO13请使用日志错误更新您的问题Yes@Kenly说的是正确的事情…问题在于当您尝试在

中获取
计算的值时，如果self.computation='fixed'：
。您需要在
self
上循环以获取字段值。您可以查看文档
@api.depends('computation', 'fixed')
def compute_deduction(self):
    if self.computation == 'fixed':
        self.amount = self.fixed

    elif self.computation == 'formula':
        baselocaldict = {
            'result': None,
            'employee': self.employee_id,
            'deduction': self}
        localdict = dict(baselocaldict)
        try:
            Eval(self.formula, localdict, mode='exec', nocopy=True)
        except BaseException:
            raise ValidationError(
                    _('Error in the formula defined for this\
                      deduction: %s\n [%s].') %
                    (self.name, self.formula))
        self.amount = localdict['result']
    else:
        self.amount = 0.00
