Concurrency exception when I use PaymentModule with own PaymentRequestGateway #8608
Answer

Hi, thanks for sending me the following files:

  • PaymentRequestAppService.cs
  • PaymentCompletedHandler.cs
  • SubscriptionCanceledHandler.cs
  • SubscriptionCreatedHandler.cs
  • SubscriptionUpdatedHandler.cs

Unfortunately I could not find the cause in these files...

Where else is an update made on the PaymentRequest?

Concurrency exception when I use PaymentModule with own PaymentRequestGateway #8608
Answer

Here is an excerpt from the log file, I have tried to make as many log messages as possible. But unfortunately I can't see where exactly the exceptions are happening, as this seems to come from your module.

Due to the character limitation in two parts...

You can publish an event in PalmaTenantDatabaseMigrationHandler

Ah yes, that's it. Thank you!

Hide or protect admin user #7896
Answer

Ok, I've seen the problem. It's because my TenantEventHandler was called first and then PalmaTenantDatabaseMigrationHandler, which creates the admin user.

Probably you can't specify a order?

I would simply prefer to have my logic in a separate EventHandler, as there are also further steps (sending mail etc.) which have nothing to do with database migration...

    public async Task HandleEventAsync(TenantCreatedEto eventData)
    {
        await MigrateAndSeedForTenantAsync(
            eventData.Id,
            eventData.Properties.GetOrDefault("AdminEmail") ?? PalmaConsts.AdminEmailDefaultValue,
            eventData.Properties.GetOrDefault("AdminPassword") ?? PalmaConsts.AdminPasswordDefaultValue
        );

        using (_currentTenant.Change(eventData.Id))
        {
            // Set admin user as confirmed
            var adminUser = await _userManager.FindByEmailAsync(PalmaConsts.AdminEmailDefaultValue);
            if (adminUser != null)
            {
                adminUser.SetEmailConfirmed(true);
                await _userManager.UpdateAsync(adminUser);
            }
        }
    }
Hide or protect admin user #7896
Answer

Another problem: After creating the tenant (TenantAppService.CreateAsync), I would like to change something about the user. But it seems that the user is not yet in the database. It is not (yet) found...

Is the transaction only completed after all EventHandlers have been handled? Or is this a timing problem?

public class TenantEventHandler : IDistributedEventHandler<TenantCreatedEto>, ITransientDependency
{
    private readonly IdentityUserManager _userManager;
    private readonly ICurrentTenant _currentTenant;

    public TenantEventHandler(IdentityUserManager userManager, ICurrentTenant currentTenant)
    {
        _userManager = userManager;
        _currentTenant = currentTenant;
    }

    public async Task HandleEventAsync(TenantCreatedEto eventData)
    {
        using (_currentTenant.Change(eventData.Id))
        {
            // Set admin user as confirmed
            var adminUser = await _userManager.FindByEmailAsync(PalmaConsts.AdminEmailDefaultValue);
            if (adminUser != null)
            {
                adminUser.SetEmailConfirmed(true);
                await _userManager.UpdateAsync(adminUser);
            }
        }
    }

[AllowAnonymous] works, thank you for the hint.

Hide or protect admin user #7896
Answer

I am using version 8.2.2... maybe it's already fixed in 8.3?

maybe you can try

It's not that important to me, I just wanted to make a contribution to improving ABP.

My next problem: The tenant should be created automatically when a customer registers. Now, of course, I have a problem with the permissions, as certain rights are required to create a tenant and an anonymous user cannot have these.

I have already extended the TenantAppService and the CreateAsync method, but the permissions are taken from the base class.

How can I achieve my goal?

Answer

You don't need to extend TenantAppService, you can use data seeder.: https://abp.io/docs/latest/framework/infrastructure/data-seeding

Thank you, that worked.

Answer

Not yet definitely. We have to wait for a few decisions from the customer and I would therefore like to leave the question open so that we can ask again later if necessary.
