In some case it's useful to return error information to the users. But not everyone should see everything and settings.DEBUG should normally be disabled.
Here is a way to return different information to different users:

# insert more information into the traceback and re-raise the original error
etype , evalue , etb = sys . exc_info ()
evalue = etype ( ' %s (More info: %s )' % ( msg , evalue ))
raise etype , evalue , etb
if request . user . is_staff :
# add more info for staff members
msg += u" ( %s )" % err
if request . user . is_superuser :
# put the full traceback into page_msg, but only for superusers
messages . debug ( request , mark_safe ( " %s :<pre> %s </pre>" % ( msg , traceback . format_exc ())))
return u"[ %s ]" % msg
