我有一个定制的500汉德与哨兵一起使用.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:

这真让我抓狂.任何建议将不胜感激
开发和生产之间的设置绝对 100% 相同吗？
确保您django.core.context_processors.request的TEMPLATE_CONTEXT_PROCESSORS
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。
希望情况确实如此！
