Naming Strategy

GORM converts struct and field names to database identifiers. By default, struct names are pluralized and snake_cased for table names; field names become snake_case column names.

Default behavior

• Post → table posts
• UserProfile → table user_profiles
• CreatedAt → column created_at

Overriding table name

func (Post) TableName() string {
    return "posts"
}

Overriding column names

Email string `gorm:"column:email_address"`

Custom naming in GORM

Configure GORM at connect time with NamingStrategy:

db, err := gorm.Open(dialector, &gorm.Config{
    NamingStrategy: schema.NamingStrategy{
        SingularTable: true,  // Post → post, not posts
    },
})
