Question on Db Migrations in a Multi-Tenant environment with each tenant having separate databases. #4859
Question

ABP Commercial 7.0.1 / Blazor Server / EF / Non tiered / Separate Host DB, Separate Tenant DBs

What is the transactional behavior when the migrator is migrating multiple tenant databases?

If a particular tenant exceptions out, does just that tenant's migration roll back or will all tenants that have already been migrated in the process also roll back?

Thanks in advance!

Preventing tenant's SQL user name and password from being in plain text in the SaasTenantConnections table #4853
Answer

Hi @liangshiwei

Thank you for taking the time to setup the scenario!

The problem was that I didn't override the obsolete non-async version of the Resolve method.

I'll close the issue.

Preventing tenant's SQL user name and password from being in plain text in the SaasTenantConnections table #4853
Question

ABP Commercial 7.0.1 / Blazor Server / EF / Non tiered / Separate Host DB, Separate Tenant DBs

For security reasons, we are currently saving the tenant connection strings to the database without a user name and password

We then overrode the MultiTenantConnectionStringResolver so that we can fill in the user name and password at run time based on values we have stored in Azure Key Vault.

The problem we are having is that at certain point, when logging into a tenant, the method below in our MultiTenantConnectionStringResolver is called by ABP with _currentTenant.Id == null and the framework returns the host connection string, but immediately after that there is an exception occurring because, in the tenant database, there is no user name or password in the connection string.

There must be somewhere else in the frame work that we need to override, but we can't seem to figure it out from the stack trace.

I've included the stack trace below...

    public override async Task<string> ResolveAsync(string connectionStringName = null)
    {

        if (_currentTenant.Id == null)
        {
            //No current tenant, fallback to default logic
            return await base.ResolveAsync(connectionStringName);
        }
        
        // we have logic below here to update the connection string when _currentTenant.Id is a tenant and not the host....
        ....
        //return our custom connection string
        ....

Overriding default 404 error page in Blazor Server template w/Lepton theme #4787

That was easy and worked perfectly. Thanks @maliming !!

Interesting... I have the same setup. Could it be because I'm using a Blazor Server templated solution and your using MVC?

Overriding default 404 error page in Blazor Server template w/Lepton theme #4787
Answer

We created our own nVisionLeptonErrorViewComponent and added our own 404.cshtml

Our project solution is as follows:

Our 404.cshtml is as follows:

@using FM.nVision.Blazor.Views.Error.DefaultErrorComponent;
@using Volo.Abp.AspNetCore.Mvc.UI.Theme.Lepton.Views.Error.DefaultErrorComponent
@model Volo.Abp.AspNetCore.Mvc.UI.Theme.Shared.Views.Error.AbpErrorViewModel

@(await Component.InvokeAsync&ltnVisionLeptonErrorViewComponent&gt(new { model = Model, defaultErrorMessageKey = "404Message" }))

Our nVisionLeptonErrorViewComponent is as follows:

using Volo.Abp.AspNetCore.Mvc.UI.Theme.Lepton.Views.Error.DefaultErrorComponent;

namespace FM.nVision.Blazor.Views.Error.DefaultErrorComponent;

public class nVisionLeptonErrorViewComponent : LeptonViewComponentBase
{
    public IViewComponentResult Invoke(AbpErrorViewModel model, string defaultErrorMessageKey)
    {
        var leptonModel = new LeptonErrorPageModel
        {
            ErrorInfo = model.ErrorInfo,
            HttpStatusCode = model.HttpStatusCode,
            DefaultErrorMessageKey = defaultErrorMessageKey
        };

        return View("~/Views/Error/DefaultErrorComponent/Default.cshtml", leptonModel);
    }
}

We still don't see our custom Default.cshtml in Views/Error/DefaultErrorComponent. Is there something else we are missing?

MultiTenantConnectionStringResolver override/replace issue #4790
Answer

Thanks @maliming

Now I know to check base class interfaces and included them in the [ExposeServices] attribute.

MultiTenantConnectionStringResolver override/replace issue #4790
Question

ABP Commercial 7.0.1 / Blazor Server / EF / Non tiered / Seperated Host and Tenant DBs

Hi, as per the answer to... https://support.abp.io/QA/Questions/4703/Question-on-separate-databases-per-tenant

...we are attempting to override MultiTenantConnectionStringResolver

The problem is that the ResolveAsync method never gets hit in our overriden/replaced implementation when we set a brake point. Either we are not overriding/replacing the correct Abp class or there is a problem with the way we are attempting to override the resolver.

Our override/replace is defined as follows:

using Volo.Abp.MultiTenancy;

namespace FM.nVision.Saas;

[Dependency(ReplaceServices = true)]
[ExposeServices(typeof(MultiTenantConnectionStringResolver))]
public class MyMultiTenantConnectionStringResolver : MultiTenantConnectionStringResolver
{
    private readonly ICurrentTenant _currentTenant;

    public MyMultiTenantConnectionStringResolver(
        IOptionsMonitor<AbpDbConnectionOptions> options,
        ICurrentTenant currentTenant,
        IServiceProvider serviceProvider)
        : base(options, currentTenant, serviceProvider)
    {
        _currentTenant = currentTenant;

    }

    public override async Task<string> ResolveAsync(string connectionStringName = null)
    {

        return await base.ResolveAsync(connectionStringName);
    }
}

We are attempting to decrypt the connection string from the database when the framework is reading it.

Please advise and thanks in advance...

Answer

Also, LeptonErrorViewComponent's Invoke method is not overridable (virual) so the component cannot be replaced.
