Description

I am getting the following error message when trying to create a ticket:

IntegrityError: ticket.id may not be NULL

The back end database was converted from Postgres to SQLite. Here are some other details about my set up:

Trac: 0.11.2.1 Python: 2.4.3 (#1, Jun 11 2009, 14:09:37) [GCC 4.1.2 20080704 (Red Hat 4.1.2-44)] setuptools: 0.6c5 SQLite: 3.3.6 pysqlite: 1.1.7 Genshi: 0.5.1 mod_python: 3.2.8 Subversion: 1.5.5 (r34862) jQuery: 1.2.6

Thanks in advance.

I'm pretty sure this is due to the autoindex sequences in PostgreSQL not being set-up correctly by the conversion process. See #8575 for a similar symptom and how to fix the issue.

Off the top of my head, you'll probably need to do the following, assuming your schema is already correct (completely untested, so keep a backup around):

SELECT setval('ticket_id_seq', (SELECT MAX(id) FROM ticket));
SELECT setval('report_id_seq', (SELECT MAX(id) FROM report));

Anyway, we don't officially support database backend conversions, so this is not a bug in Trac. You may get more help on the MailingList and / or IrcChannel.

You may also want to check that the ticket.id and report.id columns are set up as auto-incrementing.

I think the code you have given my is for MySQL. Do you know the equivalent SQLite code? Thanks.

Oh, sorry, I misread the description and thought you converted from SQLite to PostgreSQL, when you actually did the opposite.

Make sure the id column of the ticket and report tables is of type "integer PRIMARY KEY". Other than that, I don't know.

Replying to rblank:

For posterity, in addition to this, make sure to all null for ticket.id in the SQLite3 database. I converted from a MySQL Database down to a SQLite3 database and the program I used to migrate left the mysql schemas mostly active, converting datatypes over only.
