  • ABP Framework version: V4.2.2
  • UI type: MVC
  • DB provider: EF Core
  • Tiered (MVC) or Identity Server Separated (Angular): no
  • Exception message and stack trace:
  • Steps to reproduce the issue:

I have the following code in my OnPost of a page where i am throwing a new UserFriendlyException

public virtual async Task<IActionResult> OnPostAsync()
{

    var tenant = await TenantRepository.FindByNameAsync(Tenant.Name);

    if (tenant != null)
    {

        throw new UserFriendlyException(message: "Tenant Name already exists please choose another");

However the page go to a 403 Forbidden page and not shows a popup dialog, can you let me know what I am doing wrong

    hi

    Hi @learnabp, I can't see UserFriendlyException but I'll suggest something below. If you already construct your exception same, please share your exception class too.


    Make sure your exception is a DomainException and it has an error code and your localization json files have a resource with that error code as key.

    You can examine 'AuthorAlreadyExistsException' in this sample

    i am throwing the exception in my OnPost when i submit the form on a page to check if tenant exists

    
        if (tenant != null)
        {
    
            throw new UserFriendlyException(message: "Tenant Name already exists please choose another");
    
        }

    If exception is inherited from Business exception and it has errorcode, exception detail text will be displayed from resources, exception message won't be displayed in UI automatically. You have to add a resource for errorcode of your exception

    @learnabp let me introduce for your situation:

    • As a best-practice, BusinessException should be thrown from Domain layer. So You have to create your Exception in your Domain layer:
    public class UserFriendlyException : BusinessException
    {
        public UserFriendlyException(SerializationInfo serializationInfo, StreamingContext context) : base(serializationInfo, context)
        {
        }
    
        public UserFriendlyException(string tenantName)
        {
            // As an example, place your awesome unique code here
            Code = "Acme.BookStore:0001"; 
    
            WithData(nameof(TenantName), tenantName);
        }
        public string TenantName { get; set; }
    }
    
    • You can throw like that:
        if (tenant != null)
        {
            throw new UserFriendlyException(Tenant.Name);
        }
    
    • You can localize what user sees in your localization files: en.json
      {
        "culture": "en",
        "texts": {
          "Acme.BookStore:0001": "Tenant Name {TenantName} already exists please choose another",
          //...
        }
      }
      
      You can display different messages for each language with that.

    If you create a Business Exception like that, you won't see "internal error occured".

    Let me know if that helps or not. @learnabp
