【问题描述】：

如果产品的数量是 Unicode 字符，我得到 /add/处的UnicodeEncodeError。当我设置 DEBUG = False 时，satchmo 无法处理 500 错误，无法返回 HttpResponse 对象，但 handler404 没问题。我在 apache 错误日志中找到以下内容。

这里是 500.html：

{% block content %}

    <h3>{% trans "Error" %}</h3>
    <h4>{% trans "There was an error with the store.  The admin has been notified." %}</h4>

{% endblock %}

django为什么不能处理500错误页面？

【问题讨论】：

很难说，除非您发布 500 处理程序的代码...
@Daniel Roseman 谢谢提醒
在开发服务器下运行是否得到同样的结果？
@Peter Rowell：不，这是一个错误，顺便说一句，我已经修复了这个错误。但是我想知道django为什么不能处理500错误页面。
我不知道为什么你的副本不能处理它。 使用开发服务器尝试以下操作：首先使用settings.DEBUG = True 尝试保证 500 错误（我总是喜欢 1/0）的视图，然后使用 False。如果您的 500 页面在开发服务器下正常工作，那么在您的生产服务器上尝试相同的操作：首先使用 settings.DEBUG = True，然后使用 False。请记住，您可能必须重新启动生产服务器才能使更改生效。您正在测试的是 a) 您的 500 页是否正确编写，并且 b) 您没有遇到环境问题。

【解决方案1】：

Django's documentation，

默认 500 视图通过 no 此模板的变量并且是用一个空的 Context 渲染到减少额外错误的机会

我认为你应该对你的 500.html 保持同样的方法，not 扩展 base.html，not 甚至引用 i18n，而是保持它尽可能简单。

当您收到服务器错误时，请考虑上下文：出现问题，您不知道发生了什么。您甚至可能处于未满足所有常见先决条件的情况，因此您应该使页面尽可能简单。
就个人而言，我什至避免使用图像，只依赖于一些 ASCII 艺术 :-)
