假设我有一个这样的词典列表:

[{'amount': 42140.0, 'name': 'Payment', 'account_id_credit': 385, 'type': u'expense', 'account_id_debit': 476}, 
{'amount': 43926.0, 'name': 'Payment', 'account_id_credit': 695, 'type': u'payable', 'account_id_debit': 641}, 
{'amount': 3800.0, 'name': 'Payment', 'account_id_credit': 695, 'type': u'expense', 'account_id_debit': 476},
{'amount': 46330.0, 'name': 'Payment', 'account_id_credit': 695, 'type': u'expense', 'account_id_debit': 476}, 
{'amount': 67357.0, 'name': 'Payment', 'account_id_credit': 695, 'type': u'payable', 'account_id_debit': 323},
{'amount': 26441.0, 'name': 'Payment', 'account_id_credit': 695, 'type': u'expense', 'account_id_debit': 476} ... ]

我想将字典合并在一起,以便关键的"金额"将是所有amounts字典的总和,其中account_id_credit和account_id_debit是相同的,但只有type这些是expense.其他types应该保持原样.

最好的方法是什么？

我正在尝试创建一个选择字段，其中的值应该动态计算。声明是：

payment_mode = fields.Selection('_compute_selection', string="Payment mode", default="cash")

和功能：

@api.model
def _compute_selection(self):
    context = dict(self._context or {})
    active_ids = context.get('active_ids')
    active_model = context.get('active_model')
    invoices = self.env[active_model].browse(active_ids)
    type_payment = MAP_INVOICE_TYPE_PARTNER_TYPE[invoices[0].type]
    if type_payment == "expense":
        if active_model == "account.invoice":
            payment_mode = [('cash', 'Cash'),
                ('idoklad', 'Internal'),
                ('transfer', 'Bank transfer')]
        else:
            payment_mode =  [('cash', 'Cash'),
                ('transfer', 'Bank transfer')]
    else:
        if active_model == "account.invoice":
            payment_mode = [('cash', 'Cash'),
                ('idoklad', 'Internal')]
        else:
            payment_mode = [('cash', 'Cash')]

    return payment_mode

所见声明：

<field name="payment_mode" widget="radio" />

但是，在模块升级时我收到此错误：
