before this works, you'll need to satisfy all the criteria for getting debug information in your template context:

Have 'django.core.context_processors.debug' in your TEMPLATE_CONTEXT_PROCESSORS setting (it was there in the default settings, last time I checked). Have your current IP in your INTERNAL_IPS setting. Use RequestContext when rendering the current template (if you're using a generic view, you're already using RequestContext).
