发生其他异常时引发Unicode异常

标签： django

我在运行的django项目（1.11）中有这种奇怪的行为（例如，来自开发服务器的示例）：首先，我收到记录错误，这可能与设置有关 但是，真正奇怪的是：每当引发异常时，都会导致Unicode错误。我假设语言设置或python版本干扰可能存在问题？

这是视图-我添加了零除以导致错误。当我删除它时，一切正常：

class TestView(TemplateView):
    template_name = "table.html"

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        dummy=1/0
        return context

以下是错误日志：

我已经在这里显示-我认为-错误日志的重要部分。记录错误和unicode错误会显示更多次。所以我的基本问题是，每当发生异常时，我都会得到20个Unicode期望值和10个记录错误，这使得很难找到真正的异常。

答案 0 :(得分：1)

您的模型 str 无法正确处理Unicode。我建议您使用UTF-8编码。为此，请将其放在您的.py模块/文件的开头：

# -*- coding: utf-8 -*-

如果这不起作用，请尝试：

def __str__(self):
return self.name.encode('utf8')

或使用：

class TestView(TemplateView):
    template_name = "table.html"

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        dummy=1/0
        return context.encode('utf-8')
