You can accomplish that with ' Smart Select Fields '

type APIShopCategory struct {
    ID uint
    Name string
    Slug string
}


func GetShopCategory(c *fiber.Ctx) error {
    var shopCategories []APIShopCategory
    err := model.DB.Model(&model.ShopCategory{}).Find(&shopCategories)
    if err.Error != nil {
        return c.SendStatus(fiber.StatusNoContent)
    }
    return c.JSON(shopCategories)
}
