Once the InitSchema function is called, the contents of []*gormigrate.Migration are not executed as expected.

My database is clean, without any tables.

I want to InitSchema and do some other migrations, just like this:

	m := gormigrate.New(db, gormigrate.DefaultOptions, []*gormigrate.Migration{
		&gormigrate.Migration{
			ID: "20230716",
			Migrate: func(tx *gorm.DB) error {
				return tx.Exec("INSERT INTO user (username) VALUES ('admin')").Error
			},
			Rollback: func(tx *gorm.DB) error {
				return tx.Exec("DELETE FROM user WHERE username='admin'").Error
			},
		},
	})
	m.InitSchema(func(tx *gorm.DB) error {
		err := tx.AutoMigrate(
			&User{},
			// all other tables of you app
		)
		return err
	})
	if err := m.Migrate(); err != nil {
		log.Fatalf("Migration failed: %v", err)
	}
	log.Println("Migration did run successfully")

However, the sql INSERT INTO user (username) VALUES ('admin') was not executed as expected.

I then checked the source code of this library. There is only insertMigration in this place:

gormigrate/gormigrate.go

Lines 347 to 351 in 293e5ee

	for _, migration := range g.migrations {
	if err := g.insertMigration(migration.ID); err != nil {
	return err
	}
	}

Is migration.Migrate(g.tx) missing. Or should it be call g.runMigration(migration.ID) instead of g.insertMigration(migration.ID)?

The problem seems to be on the actual migrate function

https://github.com/go-gormigrate/gormigrate/blob/56c66f9d1f074e78fd0ce4693399347385a746c2/gormigrate.go#L186C2-L207

After it runs the initSchema it returns before doing the actual migration that was supposed to run

To confirm, is this a bug or intended behaviour? We have a lot of duplication between initSchema and our regular migrations because only one of them runs at any given time.

Is there a solution to this problem?
