Description
I'm currently attempting to debug what appears to be an error handling bug in Django REST Framework: https://github.com/tomchristie/django-rest-framework/issues/3446
However, the error I *really* want to be investigating is the original one, rather than the secondary failure in the DRF exception handling.
Python 3 captures this information in the __context__ (or __cause__) attribute on the exception object, as described in https://www.python.org/dev/peps/pep-3134/
It would be handy if the DEBUG view could be updated to display that information when it was available (although I have no idea how difficult such a change would be)
Note:
See TracTickets
for help on using tickets.
I believe this is done in Django 1.9 (see #23643).
