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

这是500.html：

{% extends "base.html" %}
{% load i18n %}

{% block navbar %}
   <li class="first"><a href="{{ shop_base }}/">{% trans "Home" %}</a></li>
{% endblock %}

{% block content %}

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

{% endblock %}

这是base.html：

{% load i18n satchmo_category satchmo_google satchmo_util satchmo_currency satchmo_discounts app_plugins normalize_decimal %}
{% block doctype %}<?xml version="1.0" encoding="UTF-8"?>

为什么django不能处理500错误页面？

通过Django 的文档，

默认的 500 视图不向此模板传递任何变量，并使用空的 Context 进行渲染，以减少出现其他错误的机会

我认为你应该对你的 500.html 保持相同的方法，不扩展 base.html，甚至不引用 i18n，而是尽可能简单。

当你得到一个服务器错误时，考虑一下上下文：出了点问题，你不知道是什么。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，只依赖一些 ASCII 艺术 :-)
