AttributeError: 'bool' object has no attribute 'strftime'

Question

我正在继承 'account.partner.ledger' 模块。当我们 select 客户时，我们将能够打印客户分类帐的报告。在合作伙伴分类帐菜单中，如果过滤器是 date/period，我想默认选中 'include Initial Balances' 复选框。我试图通过我的自定义模块覆盖该方法，但我无法解决我遇到的错误得到.

代码，

@api.multi
def onchange_filter(self,filter='filter_no', fiscalyear_id=False):
    res = super(account_partner_ledger, self).onchange_filter(filter=filter, fiscalyear_id=fiscalyear_id)
    if filter in ['filter_no', 'unreconciled']:
        if filter == 'unreconciled':
            res['value'].update({'fiscalyear_id': False})
        res['value'].update({'initial_balance': False, 'period_from': False, 'period_to': False, 'date_from': False ,'date_to': False})

    if filter in ['filter_date','filter_period']:
        res['value'].update({'initial_balance': True, 'period_from': True, 'period_to': True, 'date_from': True ,'date_to': True})
    return res

错误，

Answer 1

有时您必须查看底层代码以了解发生了什么，您会收到错误，因为 Odoo 正在尝试将布尔对象转换回时间的字符串表示形式（它期望 python 日期对象)

您可以启动终端并重现您的错误：

>>> True.strftime
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'bool' object has no attribute 'strftime'
>>>

这是来自 odoo

的 to_string 方法

@staticmethod
def to_string(value):
    """ Convert a :class:`date` value into the format expected by the ORM. """
    return value.strftime(DATE_FORMAT) if value else False

测试条件 if value 测试以查看 value 是否评估为 False，从终端测试

>>> x = ''
>>> if x: print('Yeah')
... 
>>> 
>>> x = True
>>> if x: print('Yeah')
... 
Yeah
>>> x = False
>>> if x: print('Yeah')
... 
>>> 
>>>

从输出中，我们可以得出一个结论，即空字符串或 False 的计算结果为 False，而 True 值的计算结果为 True，因此不要将日期值设置为 True，而是将它们全部设置为空字符串。

@api.multi
def onchange_filter(self,filter='filter_no', fiscalyear_id=False):
    res = super(account_partner_ledger, self).onchange_filter(filter=filter, fiscalyear_id=fiscalyear_id)
    if filter in ['filter_no', 'unreconciled']:
        if filter == 'unreconciled':
            res['value'].update({'fiscalyear_id': False})
        res['value'].update({'initial_balance': False, 'period_from': False, 'period_to': False, 'date_from': False ,'date_to': False})

    if filter in ['filter_date','filter_period']:
        res['value'].update({'initial_balance': 'True', 'period_from': '', 'period_to': '', 'date_from': '', 'date_to': ''})

    return res

Answer 2

当您查看代码时，您会看到：

'date_from': True ,'date_to': True

这会导致您的错误。您应该将这些字段设置为日期而不是布尔值。值 False 有效，因为您应该可以不填写日期。

Answer 3

尝试使用 strptime 而不是 strftime，看看是否能解决问题。您可以使用 strptime，例如：-

from openerp.tools import DEFAULT_SERVER_DATETIME_FORMAT my_date = datetime.strptime(self.date_column, DEFAULT_SERVER_DATETIME_FORMAT)
