AttributeError: Cursor instance has no attribute ‘connection’

I’m experiencing the same problem as the first Alex, where there’s a fatal error on upgrading trac (by ‘trac-admin /var/lib/trac/my_project upgrade’) and when I try to open the Burndown menu.

The exception is:

My configuration is:

Trac: 0.11.5
Python: 2.5.2 (r252:60911, Jul 22 2009, 15:52:25)
setuptools: 0.6c8
pyPgSQL: 2.5.1
Genshi: 0.5.1
mod_python: 3.3.1
Subversion: 1.4.6 (r28521)
jQuery: 1.2.6

thanks for this superb plugin! Any news on the schedule for the new version you mentioned?

Thanks!

Is there anywhere I can get hold of the latest source? Trac-hacks only has up to 1.9.1, and I’d like to tinker with the code before building an egg. I don’t see much point in making my modifications based on 1.9.1 if you’re about to change a lot anyway.

Thanks,
Dave.

Would love to try the plugin, any clue what might be going wrong?

trac-admin /home/techops-tracd/yfroot/webapps/trac/changes upgrade
Command failed: Cursor instance has no attribute ‘connection’

Now whole trac is broken. If there is no quick fix then how do I uninstall the plugin.

Any help is much appreciated. We have lots of data on to our trac.

Thanks,
Abhay

It’s untested, but you can try…
