What is transaction atomicity in GORM?

Can you explain what transaction atomicity means in GORM?

Transaction atomicity in GORM ensures that a series of database operations are completed successfully as a single unit. If any operation fails, the entire transaction is rolled back.

Why is atomicity important in database transactions?

Atomicity is crucial because it maintains data integrity. It ensures that either all operations succeed or none do, preventing partial updates that could lead to inconsistent data.

How do I implement atomic transactions in GORM?

You can implement atomic transactions in GORM using the db.Transaction method, which allows you to group multiple operations into a single transaction.

Can you give me an example of using transactions 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
})
