TypeError：類型為'bool'的對象沒有len（）-Odoo v9

Question

我正在嘗試通過Odoov9模塊連接到Web服務。

這是我的課：

class invoice(models.Model):
_inherit = "account.invoice"

@api.multi
def send_xml_file(self):
    # haciendolo para efacturadelsur solamente por ahora
    host = 'https://www.efacturadelsur.cl'
    post = '/ws/DTE.asmx' # HTTP/1.1
    url = host + post
    _logger.info('URL to be used %s' % url)
    # client = Client(url)
    # _logger.info(client)
    _logger.info('len (como viene): %s' % len(self.sii_xml_request))

    response = pool.urlopen('POST', url, headers={
        'Content-Type': 'application/soap+xml',
        'charset': 'utf-8',
        'Content-Length': len(
            self.sii_xml_request)}, body=self.sii_xml_request)

    _logger.info(response.status)
    _logger.info(response.data)
    self.sii_xml_response = response.data
    self.sii_result = 'Enviado'

但是每次它解析代碼以連接到服務器時，都會引發此錯誤：

Odoo Server Error

TypeError: object of type 'bool' has no len()

錯誤在這條線上

_logger.info('URL to be used %s' % url) # client = Client(url) # _logger.info(client) _logger.info('len (como viene): %s' % len(self.sii_xml_request))

我已經搜索過SO，它似乎與括號有關，但是我仍然不確定。

有什么想法嗎？

提前致謝！

編輯

這是設置它的代碼：

    sii_xml_request = fields.Text(
    string='SII XML Request',
    copy=False,
    )

當您嘗試訪問self.sii_xml_request時。 首先檢查它的值是否為空。

在您的情況下，它返回一個空字符串False 。 為避免這種情況，請嘗試以下代碼：

_logger.info('len (como viene): %s' % (len(self.sii_xml_request) if self.sii_xml_request else '')

如果其中包含值，則只會記錄“ self.sii_xml_request”。 否則，它將只記錄一個空字符串。 您當然可以更改此設置，以記錄與“ self.sii_xml_request”中沒有值的其他顯示內容。
