  Hi,

  You can write a domain event to handle this, see https://aspnetboilerplate.com/Pages/Documents/EventBus-Domain-Events#entity-changes.

  Here is a similar example, https://github.com/aspnetboilerplate/aspnetboilerplate/blob/dev/src/Abp.Zero.Common/Authorization/Users/UserAccountSynchronizer.cs.

  Hi,

  I tried to get what I needed with the help of domain events. But I have a problem.

  Suppose this: When I create a User1 in tenant A, my domain activity is triggered. In the case of domain, I add the new user with the same attributes to the Default tenant. however, this action triggers my domain activities again.

  I am having the same problem updating user information. For example, when I change the user's last name in Tenant A, my domain activity is triggered, so I update the user's last name in Tenant Default, but again this update repeats the triggers domain event.

  Any solution to turn off the domain event in a section of the code? Or is there any way to get any information that shows me that the event was routed by the system and not the end user?

  Here is my code for recreate user in default tenant:

   public virtual void HandleEvent(EntityCreatingEventData<AbpUserBase> eventData)
          {
              //If user is not being added to host or default tenant
              if (eventData.Entity.TenantId != null && eventData.Entity.TenantId != 1)
              {
                  //Workining on default tenant
                  using (_unitOfWorkManager.Current.SetTenantId(1))
                  {
                      //Get all users of default tenant
                      IQueryable<User> allUser = _userRepository.GetAll();
  
                      //Get user with same email or username
                      var defaultTenantUser = allUser.FirstOrDefault(ua => ua.TenantId == 1 && (ua.UserName == eventData.Entity.UserName || ua.EmailAddress == eventData.Entity.EmailAddress));
  
                      //If user with same email or username is not available in default tenant
                      if (defaultTenantUser == null)
                      {
                          //add "User" Role to new user roles
                          var userRoles = new Collection<UserRole>();
                          var defaultRole = _roleRepository.FirstOrDefault(r => r.Name == Pudux.Authorization.Roles.StaticRoleNames.Tenants.User);
                          userRoles.Add(new UserRole(1, eventData.Entity.Id, defaultRole.Id));
  
                          var userToAdd = new User
                          {
                              TenantId = 1,
                              UserName = eventData.Entity.UserName,
                              Name = eventData.Entity.Name,
                              Surname = eventData.Entity.Surname,
                              EmailAddress = eventData.Entity.EmailAddress,
                              Password = eventData.Entity.Password,
                              PasswordResetCode = eventData.Entity.PasswordResetCode,
                              EmailConfirmationCode = eventData.Entity.EmailConfirmationCode,
                              IsActive = eventData.Entity.IsActive,
                              IsDeleted = eventData.Entity.IsDeleted,
                              IsEmailConfirmed = eventData.Entity.IsEmailConfirmed,
                              IsLockoutEnabled = eventData.Entity.IsLockoutEnabled,
                              IsPhoneNumberConfirmed = eventData.Entity.IsPhoneNumberConfirmed,
                              IsTwoFactorEnabled = eventData.Entity.IsTwoFactorEnabled,
                              NormalizedEmailAddress = eventData.Entity.EmailAddress.ToUpperInvariant(),
                              NormalizedUserName = eventData.Entity.UserName.ToUpperInvariant(),
                              Roles = userRoles,
                          };
  
                          //add user to default tenants
                          _userRepository.Insert(userToAdd);
                      }
                  }
              }
          }

  Hi @bulutyonetim

  You are right, it will trigger same event and it will cause an endless loop. Another option would be overriding CreateAsync method of UserManager and create duplicate user entity on another tenant.

  Hi,

  Thanks for answer. What is best practice of overriding CreateAsync method of UserManager. I do not want my code be lost when I update my project to lateset Asp.net Zero in future.

  Hi @bulutyonetim

  You can directly implement it in the UserManager class. We don't modify this class. If we need to make any modifications on CreateAsync method, we basically change the AbpUserManager base class.
