}

func (u User) Valid() (bool, validator.Errors) {
	return validator.ByJSON(u, validator.Validators{
		"name":    validator.StringRequire(u.Name, validator.Shorter(2)),
		"email":   validator.StringRequire(u.Email, validator.Email()),
		"message": validator.StringOption(u.Message, validator.Longer(10)),
