英文:
Need to validate two fields in go-playground/validator/v10
问题
需要检查至少一个字段应该存在，即电子邮件和电话至少一个是必需的。
目前我有自定义验证器。
func validateEmailPhone(fl validator.FieldLevel) bool {
user := fl.Top().Interface().(models.User)
validate := validator.Validate{}
if user.Email == "" && user.Phone == "" {
return false
}
if user.Email != "" {
if err := validate.Var(user.Email, "email"); err != nil {
return false
}
}
if user.Phone != "" {
if err := validate.Var(user.Phone, "e164"); err != nil {
return false
}
}
return true
}
但是它会引发恐慌。
用户是gorm模型。
在这种情况下，如何检查这两个字段？
英文:
need to check atleast one of field should be present email, phone atleast one is mandatory
currently I have custom validator
func validateEmailPhone(fl validator.FieldLevel) bool {
user := fl.Top().Interface().(models.User)
validate := validator.Validate{}
if user.Email == "" && user.Phone == "" {
return false
}
if user.Email != "" {
if err := validate.Var(user.Email, "email"); err != nil {
return false
}
}
if user.Phone != "" {
if err := validate.Var(user.Phone, "e164"); err != nil {
return false
}
}
return true
}
but its panic
the user is gorm model
in this scenario how to check these two fields

在validator中有很多条件性的required标签。
在你的情况下，你可能想要使用required_without_all + omitempty。
required_without_all - 如果列表中的所有字段都为空，则使字段为必需。
omitempty - 允许字段为空。
请记住，required标签必须在omitempty之前。
英文:
There are plenty of conditional required tags in validator.
In your case, you probably want required_without_all + omitempty.
required_without_all - makes a field required if all fields in the list are empty.
omitempty - simply allows the field to be empty.
Please keep in mind that the required tag must come before omitempty.
