type User struct {
	ID       int
	UserName string `gorm:"not null;size:100;unique"`
}

var users []User
db = db.Where("id > ?", 0)

pagination.Pagging(&pagination.Param{
    DB:      db,
    Page:    1,
    Limit:   3,
    OrderBy: []string{"id desc"},
}, &users)

r := gin.Default()
r.GET("/", func(c *gin.Context) {
    page, _ := strconv.Atoi(c.DefaultQuery("page", "1"))
    limit, _ := strconv.Atoi(c.DefaultQuery("page_size", "3"))
    var users []User

    paginator := pagination.Pagging(&pagination.Param{
        DB:      db,
        Page:    page,
        Limit:   limit,
        OrderBy: []string{"id desc"},
