【中文标题】Django 保存到 DB：TypeError：int() 参数必须是字符串、类似字节的对象或数字，而不是“元组”【英文标题】：Django save to DB: TypeError: int() argument must be a string, a bytes-like object or a number, not 'tuple' 【发布时间】：2017-10-27 16:14:28 【问题描述】：我在将数据保存到数据库时遇到了问题。
@staticmethod
def _save(account, proxy,
proxy_provider_id, period,
country, start_date,
price, meta,
account_type, ip):
try:
period = int(period)
end_date = start_date + timedelta(days=period)
prx = Proxy()
prx.account = account
prx.proxy = proxy
prx.proxy_provider_id = proxy_provider_id
prx.period = period,
prx.country = country,
prx.start_date = start_date
prx.end_date = end_date
prx.price = price
prx.meta = meta
prx.ip = ip
print('\n')
print('Save proxy '.format(prx))
print('account: type '.format(account, type(account)))
print('proxy: type '.format(proxy, type(proxy)))
print('proxy id: type '.format(proxy_provider_id, type(proxy_provider_id)))
print('country: type '.format(country, type(country)))
print('start date: type '.format(start_date, type(start_date)))
print('end date: type '.format(end_date, type(end_date)))
print('price: type '.format(price, type(price)))
print('meta: type '.format(meta, type(meta)))
print('ip: type '.format(ip, type(ip)))
print('\n')
prx.save() # exception raised there
payment = [start_date.strftime('%Y/%m/%d'),
end_date.strftime("%Y/%m/%d")]
payments = json.loads(account.history_of_payments)
payments.append(payment)
account.history_of_payments = json.dumps(payments)
account.account_type = account_type
print('\n')
print('Save account '.format(prx))
print('payment: type '.format(payments, type(payments)))
print('account type: type '.format(account_type, type(account_type)))
print('\n')
account.save(update_fields=['history_of_payments', 'account_type'])
log.debug('Update account '.format(account))
except Exception:
raise ProxyException('Exception, when trying to save proxy for '
'date price meta '
.format(proxy, country, account.username,
start_date, price, meta))
else:
log.info('Save new proxy for from to price meta '
.format(proxy, country, account.username,
start_date, end_date, price, meta))
return True
我不知道是什么原因导致了这个异常，因为我没有尝试保存任何元组。您可以查看日志。只有 srting、float、object、datetime 和 int 类型。
TypeError: int() argument must be a string, a bytes-like object or a number, not 'tuple'

如果我使用原始 SQL 查询会更好吗？
【问题讨论】：
【参考方案1】：您在设置prx.country 的行的末尾有一个逗号，这会将其转换为一个元组。
这段代码中有很多奇怪的东西。最重要的是，你真的不应该只为了引发自己的异常而捕获所有异常；你应该抓住你知道你可以处理的错误（并实际处理它们，而不是引发另一个错误）；其他一切都应该让 Django 自己处理。
