Description (last modified by coderanger)

I finally got the plugin installled and ran the upgrade to the database which it said ran successfully, and now I'm getting a "no such column:" error.

The traceback is as follows (typed in by hand):

Traceback (most recent call last):
  File "E:\Python23\Lib\site-packages\trac\web\", line 131, in run dispatch_request(req.path_info, req, env)
  File "E:\Python23\Lib\site-packages\trac\web\", line 139, in dispatch_request dispatcher.dispatch(req)

DatabaseError: no such column:

Any suggestions?

Check if forum table exists, if don't try to clear all DiscussionPlugin database entries (if you know how) and run trac-admin upgrade again. Maybe error in updating existing db shema. This part is not well-coded yet. New installation should be clear.

I have tried to get access to the trac.db database through SQLite with no success. It tells me that the trac.db is either encrypted or not a database. I know that is not a DiscussionPlugin issue specifically, but maybe you can help shed some light on the subject. I am using Trac 0.9.3 with Python 2.3 on a Windows 2000 Server. The SQLite version is 2.8.16. Trac and Subversion are being served by Apache 2.0.54.

I had this issue some time ago too. See

The only time I get the “file is encrypted or is not a database” error is when I try to access the DB from the DOS command prompt with the sqlite.exe program. Otherwise DB access seems to be fine through Trac except for the "no such column:" error for this plugin. If I understand the TracUpgrade page correctly, I need to upgrade from SQLite 2.8.x to 3.x if I have upgraded from Trac 0.8.x to 0.9.x. Is that right?

Yes it is. Perhaps your sqlite.exe is version 2 and your database is version 3.

Could you please evoke this error with 836 and post cut from debug log?

Replying to Blackhex:

Could you please evoke this error with 836 and post cut from debug log?

I was able to fix the problem by upgrading to sqlite3.exe and pysqlite-2.2.2 for Windows. Once I did those two things, I was able to access the database correctly and the plugin started working.

So that means that it's invalid.
