Sentry 自定义 500 处理程序答案

【问题描述】：

我有一个自定义的 500 处理程序用于哨兵。在我的 urls.py 文件中，我有：

def handler500(request):
    """
    500 error handler which includes ``request`` in the context.

    Templates: `500.html`
    Context: None
    """
    from django.template import Context, loader
    from django.http import HttpResponseServerError

    t = loader.get_template('500.html') # You need to create a 500.html template.
    return HttpResponseServerError(t.render(RequestContext(request)))

在我的 500.html 模板中：

{% extends "intranet/index.html" %}

{% block main_content %}
<h1>Internal Error!</h1>
<p>You've encountered an error, please try again in some time or file an 
error report if the problem persists. 
{% if request.sentry.id %}
You may reference this error as <strong>{{ request.sentry.id }}</strong>.
{% endif %}
</p>
{% endblock %}

这适用于我的本地计算机，但不适用于我的虚拟主机。 apache 日志包含此错误：

这快把我逼疯了。任何建议将不胜感激

【解决方案1】：

您的设置在开发和生产之间是否完全 100% 相同？

确保您的TEMPLATE_CONTEXT_PROCESSORS 中有django.core.context_processors.request

虽然我在您的模板中没有看到任何应该大声抱怨的内容，但您必须在另一个模板中存在导致此问题的内容。

希望是这样！

【讨论】：

有一些不同的设置，但这只是调试等，它们位于我导入的不同 local_settings 文件中。
另外，我的设置中有“django.core.context_processors.request”。有任何想法吗？我在边缘，我随时都会扯掉我的头发：D
是的，仅在 500 页面上：'(
@Yuji'Tomita'Tomita “虽然我在您的模板中没有看到任何应该大声抱怨的内容”——模板尝试访问请求的属性：request.sentry.id
@zsquare django.core.context_processors 已移入 django 1.10，因此您现在需要 django.template.context_processors.request

【解决方案2】：

由于另外两个原因（除了TEPMLATE_CONTEXT_PROCESSORS 中的缺失部分），我出现了同样的错误：

模型已过时 - 运行 syncdb 并迁移，这会消失
urlconf 没有在 urls.py 中定义 - 所有 urlconfs 都被整齐地注释掉了。
