database error while running migration

[Federico Bruni]

Hi all

I have a problem with the database migration during a deployment.

I have changed only the LANGUAGE_CODE variable in settings.py
When I launch 'fab deploy' I get this error:

'''
out: django.db.utils.ProgrammingError: ERROR:  the relation "conf_setting" already exists
[xx.xx.xx.xx] out:
[xx.xx.xx.xx] out:

Fatal error: run() received nonzero return code 1 while executing!

Requested: /home/fede/.virtualenvs/test/bin/python /home/fede/.virtualenvs/test/project/manage.py migrate --noinput
Executed: /bin/bash -l -c "cd /home/fede/.virtualenvs/test/project && source /home/fede/.virtualenvs/test/bin/activate && /home/fede/.virtualenvs/test/bin/python /home/fede/.virtualenvs/test/project/manage.py migrate --noinput"

Aborting.
'''

What should I check?
Thanks in advance
Federico

Any pointer?
I don't want to destroy the project and re-deploy from scratch.

Hey Federico, shot in the dark here, but was South definitely installed when you deployed in the first place?  I'm wondering if some of the records of migrations are missing.

I could be totally off and I'm not sure how changing the language code would affect the db.

Hey Josh

no, South was not installed. I thought it was a dependency of Mezzanine, but I see that it's optional:
https://pypi.python.org/pypi/Mezzanine/3.1.5

I've installed it, added it to the requirements and pushed to the repository, but I'm getting the same error.

I've deployed from scratch. I'll see next time..

Thank you

Federico
