python - Django: How to get exception instance in error handlers -

django has built-in default views used automatically when exceptions such permissiondenied, http404, suspiciousoperation, etc. raised. convenient feature of django love, seems have limitation.

i raising exception message: raise permissiondenied('you not xyz , have no access foobar')

is there context variable containing original exception instance available in templates (i.e. 403.html) called original error handlers can access message?

if not, possible hold of original exception custom handler (settings.handler403, etc.) can inject context?

note: believe can create custom middleware process_exception, avoid if possible since guess duplicating lot of existing django logic , it's cleaner reuse it. also, looks custom process_exception override logging in django.core.handlers.base amongst other behaviors. re-implementing sake of injecting exception info error template seemed kind of silly.

this feature has been implemented ticket 24733.

in django 1.9 , later, exception passed error handlers.
