How do I use transactions in GORM?

In GORM, you can use transactions by creating a new transaction context. You can do this using the db.Transaction method.

Can you show me an example of a transaction in GORM?

Sure! Here's a simple example:

err := db.Transaction(func(tx *gorm.DB) error {
    if err := tx.Create(&user).Error; err != nil {
        return err
    }
    if err := tx.Create(&profile).Error; err != nil {
        return err
    }
    return nil
})

What happens if an error occurs during the transaction?

If an error occurs, the transaction will be rolled back automatically, ensuring data integrity.

Are there any best practices for using transactions in GORM?

Yes, it's best to keep transactions short, avoid long-running transactions, and handle errors properly to ensure reliability.
