I've got a working site, but I made a copy of the database in order to do
some development work.
I've hit a snag that looks like a problem in the data.
The odd part is that this database is in production, and my backups have
the same problem. So I'm presuming my new code is broken in some way I
don't understand.
For instance, Ive written a management command to show the problem:
from django.core.management.base import BaseCommand, CommandError
from oil.models import Packet, Signature, Log, Voter
class Command(BaseCommand):
help = 'Quick test'
BaseCommand.requires_migrations_checks = True
def handle(self, *args, **options):
voters = Log.objects.all()
self.stdout.write(repr(voters[0]))
I'm suspecting a problem has crept into my Log table, because it works fine
if I change Log on the
second line of handle() to any of the other tables. If it runs as shown
here however, I get
kevin@camelot-x:/build/comprosloco$ manage oiltest
Traceback (most recent call last):

self.accepted

kevin@camelot-x:/build/comprosloco$
And I have no idea how to debug it further. The schema of Log is
sqlite> .schema oil_log
CREATE TABLE "oil_log" ("id" integer NOT NULL PRIMARY KEY AUTOINCREMENT,
"packet" integer NOT NULL, "signature" integer NOT NULL, "action"
varchar(20) NOT NULL, "criteria" varchar(150) NOT NULL, "candidates"
varchar(100) NOT NULL, "accepted" varchar(10) NOT NULL, "user_id" integer
NOT NULL REFERENCES "auth_user" ("id"), "timestamp" datetime NOT NULL);
CREATE INDEX "oil_log_packet_ecd59bc4" ON "oil_log" ("packet");
CREATE INDEX "oil_log_user_id_7f26e501" ON "oil_log" ("user_id");
sqlite>
Help???
