Disable validation for dto properties not working

Hi, I have a Dto with a property name Guid, I want set this property in server side, so I set this attribute with DisableValidation attribute and pass this dto from angular with guid value empty string. but i got status code 400 (bad request). what is solution for my scenario?

C#

public class ContentEntityBaseDto : FullAuditedEntityDto<int>
  {
      [DisableValidation]
      public Guid Guid { get; set; } = Guid.NewGuid();
  }

angular:

export abstract class ContentEntityBase extends FullAuditedEntityBase {
    guid: string  = '';
}

BTW, if it will be always null, then just don’t add it to your DTO. This would be a better design.

[DisableValidation] works for ABP. But a non-null Guid (a value type) is considered as “required” and MVC validation marks it as invalid. Even we (somehow, I don’t know) handle it with ABP, your ModelState.IsValid will be still false. So, you should make it nullable if you allow nulls to set by clients. This is the true design. Other solutions will be just workarounds.
