Comment (by tom_payne):
Well, I've had this problem again and have traced the error...
I was trying to insert null values into my booleanfield (which I shouldn't
be doing - that's what NullBooleanField is for - see #5563), but I think
it's more a question of raising any error like this.
Essentially, the bug is that you don't get a nice error message telling
you what's wrong, rather you get an irrelevant Transaction error because
the proper error message raises an exception.
The problem comes when this error is raised in loaddata.py
(django/core/management/commands/loaddata.py). The except clause (line 124
onwards) tries to print an error message using traceback.format_exc, but
this needs to be traceback.format_exception(sys.exc_type, sys.exc_value,
sys.exc_traceback). The _exc shortcut, IIRC, is only available to
print_exc.
I hope that's clear.
Tom
