How do I handle migrations in Go using an ORM?

To handle migrations in Go using an ORM, you can use libraries like Gorm or sql-migrate. Would you like a code example?

Yes, please provide a code example using Gorm.

Sure! Here's a simple example:

package main

import (
    "gorm.io/driver/sqlite"
    "gorm.io/gorm"
)

func main() {
    db, err := gorm.Open(sqlite.Open("test.db"), &gorm.Config{})
    if err != nil {
        panic("failed to connect to the database")
    }

    db.AutoMigrate(&User{})
}

type User struct {
    gorm.Model
    Name string
    Age  int
}

This code connects to a SQLite database and automatically migrates the User model.

What if I want to roll back a migration?

You can use the Migrate function to roll back migrations. For example, you can create a migration file and use the Down method to revert changes. Would you like more details on that?
