GORM-based migration workaround

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

WHY

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.

Install

go get github.com/icbd/gorm-migration

How to use

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

Migrate

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()

Rollback

It will roll it back step by step.

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

Check

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