What are GORM hooks and how do I use them?

GORM hooks are methods that allow you to execute custom logic before or after certain actions in GORM, like Create, Update, or Delete.

Can you give me an example of a GORM hook?

Sure! For instance, you can use the BeforeCreate hook to set a timestamp before a record is created.

How do I implement the BeforeCreate hook in my model?

You can implement it by defining a method named BeforeCreate in your model struct. Here's a quick example:

func (u *User) BeforeCreate(tx *gorm.DB) (err error) {
    u.CreatedAt = time.Now()
    return
}

Are there other hooks I should know about?

Yes, GORM provides several hooks like AfterCreate, BeforeUpdate, and AfterDelete that you can use for various purposes.
