Subject: Use --fake-initial for migrations if necessary
X-Git-Tag: v1.0~9^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=refs%2Fpull%2F137%2Fhead;p=cephmetrics.git

Use --fake-initial for migrations if necessary

Migrations won't work correctly if the db already exists. This manifests
in an error like:
django.db.utils.OperationalError: table "django_content_type" already exists
