1. Write migration functions with Golang
2. Register functions on MigrationManger
3. Execute the migrate or rollback command

If you've used rails, you'll be impressed by its migration management.

gorm-migration is a clumsy parody, I've implemented basic migration management, including Check, Migrate and Rollback.

go get github.com/icbd/gorm-migration

For some types of databases, you need to create the database first.

It will perform all the tasks that haven't been run yet.

db := newMemoryDB()
mm := NewMigrationManger(db, Migrate)
mm.RegisterFunctions(
    mm.createUsersTable,
    mm.addAvatarToUsers,
    mm.addEmailIndexToUsers)
mm.Migrate()

It will roll it back step by step.

# ...
mm.Type = Rollback
mm.Migrate()

# ...
mm.Type = Check
mm.Migrate()
