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

回答1:

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.
