Sentry custom 500 handler
I have a custom 500 hander to use with sentry. In my urls.py file i have:
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)))
And in my 500.html template:
{% 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 %}
This works on my local machine, but not on my webhost. The apache logs contain this error:

This is driving me crazy. Any advice would be much appreciated
Are your settings absolutely 100% the same between dev and production?
Make sure you have django.core.context_processors.request in your TEMPLATE_CONTEXT_PROCESSORS
While i don't see anything in your template that should complain this loudly, you must have something in another template causing this problem.
Hope that's the case!

I had this same error appear for two additional (in addition to the missing part in the TEPMLATE_CONTEXT_PROCESSORS) reasons:
- models were out of date - run syncdb and migrate and this went away
- urlconf was not defined in the urls.py - all urlconfs were neatly commented out.
