Python TypeError:+；的操作数类型不受支持：'；布尔'；和'；str'；-从Odoo v8到Odoo v10的迁移

我有这个方法：

@api.multi
def search_partner_seniat(self):
    """ Check vat of the partner and update iva rate
    """
    self.ensure_one()
    vat = self.vat.upper()
    res = {
        'name': _('The requested contributor does not exist'),
        'vat_subjected': False,
        'vat': vat,
        'wh_iva_agent': False,
        'wh_iva_rate': 0.0
    }

    if 'VE' in vat:
        vat = vat[2:]

    # assumption: both methods in new api style
    if self.env['res.partner'].check_vat_ve(vat): 
        res = self.env['seniat.url']._dom_giver(vat) 
    self.write(res)

    return {
        'type': 'ir.actions.act_window',
        'res_model': 'search.info.partner.seniat',
        'view_mode': 'form',
        'view_type': 'form',
        'res_id': self.id,
        'views': [(False, 'form')],
        'target': 'new',
    }

它是一个按钮，此方法调用_dom_giver，如下所示：

@api.multi
def _dom_giver(self, vat):
    """ Check and validates that the vat is a passport,
    id or rif, to send information to SENIAT and returns the
    partner info that provides.
    """

    url_obj = self.search([], limit=1)
    url1 = url_obj.name + '%s'
    url2 = url_obj.url_seniat + '%s'
    vat = self._validate_rif(vat)
    if vat:
        return self._get_rif(vat, url1, url2)
    else:
        return False

错误出现在这一行“

url1=url.obj.name+'%s'

”，完整的回溯：

最初，

\u dom\u giver

方法如下所示：

def _dom_giver(self, cr, uid, vat, context=None):
    """ Check and validates that the vat is a passport,
    id or rif, to send information to SENIAT and returns the
    partner info that provides.
    """
    if context is None:
        context = {}

    url_obj = self.browse(cr, uid, self.search(cr, uid, []))[0]
    url1 = url_obj.name + '%s'
    url2 = url_obj.url_seniat + '%s'
    vat = self._validate_rif(cr, uid, vat, context=None)
    if vat:
        return self._get_rif(cr, uid, vat, url1, url2, context=context)
    else:
        return False

有什么想法吗？

以下代码有问题：

url1 = url_obj.name + '%s'
url2 = url_obj.url_seniat + '%s'

name或url\u seniat或两者的值都为False。您正在尝试用字符串连接。我们不能连接两个不同的对象/类型。我们做过铅字铸造

尝试使用以下代码以避免错误：

name = ''
url_seniat = ''

if url_obj.name:
    name = url_obj.name

if url_obj.url_seniat
    url_seniat = url_obj.url_seniat

url1 = name + '%s'
url2 = url_seniat + '%s'

如果执行此操作，则会出现相同的错误：

False + "hello"

TypeError: unsupported operand type(s) for +: 'bool' and 'str'

这意味着url_obj的名字在odoo中是假的意味着它没有，因为 odoo将null更改为False

请在奥多论坛查看我的答案点击

这已经解决了

False + "hello"

TypeError: unsupported operand type(s) for +: 'bool' and 'str'
