Django-south not detecting DB changes

问题:

I have updated our project from svn and I have new migration files. When I use :

./work/manage.py schemamigration mypackage --auto

I have this message:

Nothing seems to have changed.

But the database has changed! Why south couldn't detect any change?

Thanks in advance

If you already have the migration files, there is no need to run schemamigration as that just generates the migration files. To apply the migration files to the database, run:

./work/manage.py migrate mypackage --merge

The merge flag will run any missed migrations as a result of an SVN update.
