If your model is changed you need to upgrade your db, you can use this plugin.

Make sure you change you setting from create-drop to update.

There are a couple of good guides you can look at, here is a good one.

Good luck!

The behavior is defined in the GORM configuration

Basically, the default for development is drop-create, which erase all the content, and recreate tables.

On more stable releases, update might be a good setting knowing that Hibernate prefer to fails that conflict.

As always, I would recommend making a backup of the DB before performing such operation on pre-production and production systems.
