如何在gorm中创建BelongTo关系(GoLang)

type User struct {
    ID       uint
    Name     string
    Profile  Profile
    ProfileID uint
}

type Profile struct {
    ID   uint
    Bio  string
}

func main() {
    db, err := gorm.Open("your_database_driver", "your_connection_string")
    if err != nil {
        panic("failed to connect database")
    }
    defer db.Close()

    db.AutoMigrate(&User{}, &Profile{})

    // Add foreign key constraint
    db.Model(&User{}).AddForeignKey("profile_id", "profiles(id)", "CASCADE", "CASCADE")
}

var user User
db.Preload("Profile").Find(&user)
