Python解释器显示错误

目前我正在XAMPP上本地运行代码

我目前的日志文件设置如下：

log.py

以下是我的意思的一个例子： views.py

sqltables.py

在上面的例子中，我在浏览器中收到一条500错误消息

我在error.log中得到了这个

Apache错误日志也不包含任何有用的内容

如何在日志文件中打印更多信息？

OP使用日志记录是不正确的

我建议始终遵循以下模式：

logging.debug("user %r", user)

这将正确处理None或3.1459等奇数值，并正确转换不可打印的字符串

最后，由于它是一个web服务器，我建议您将顶级功能包装在try/except块中，例如：

try:
    render_user_or_something()
except:
    logging.exception("oh no!")
    raise

虽然这本身并不能解决您的问题，但它会告诉您代码的错误所在。

我认为您弄错了：XAMPP使用Apache运行PHP应用程序，而不是Python应用程序。或者你设置了更高级的东西？嘿@mavroprovato，Python也可以用它来设置：检查error.log是否与log.py创建在同一路径中我知道。因此，请添加有关您的配置的更多信息感谢@qarma。不知道有关%r的信息。我会试一试的。
