Django unit testing: South-migrated DB works in MySQL, throws duplicate PK error in PostGreSQL. Am I
- by unclaimedbaggage
Hi folks,
(Worth starting off with a disclaimer: I'm very new to PostGreSQL)
I have a django site which involves a standard app/tests.py testing file. If I migrate the DB to MySQL (through South),, the tests all pass.
However in PostGresQL, I'm getting the following error:
IntegrityError: duplicate key value violates unique constraint "business_contact_pkey"
Note this happens while unit testing only - the actual page runs fine in both MySQL & PostGresql.
Really having a heckuva time figuring this one out. Anyone have ideas? Below are the Postgresql "\d business_contact" & offending tests.py method if they help. No changes made to either DB except the (same) South migrations
Thanks
