• To determine if a user logged in with a local account or via an external login (such as BankID), you can inspect the user's login providers. ABP's Identity system stores external login information in the user logins table. You can check if the current user has a login with the external provider (e.g., "BankID") to distinguish the login type. The ICurrentUser service provides access to the current user's claims, but you may need to query the user manager for external login info.

• To include a custom claim in both the access_token and id_token, you can use claims contributors in ABP. Implement IAbpClaimsPrincipalContributor and register it. In your contributor, add a custom claim (e.g., "login_type") based on the authentication context. This claim will be included in the generated tokens if added during the authentication process.

  Example:

public class LoginTypeClaimsContributor : IAbpClaimsPrincipalContributor
  {
      public Task ContributeAsync(AbpClaimsPrincipalContributorContext context)
      {
          // Example: Add a claim based on login provider
          var loginType = context.Principal?.FindFirst("amr")?.Value ?? "local";
          context.Identity.AddClaim(new Claim("login_type", loginType));
          return Task.CompletedTask;
      }
  }

• For BankID-only actions, the recommended approach is:

  1. When a user must perform a BankID-only action, check if they have a BankID external login associated.
  2. If not, prompt them to add it (initiate the external login flow).
  3. To avoid double authentication, ensure your claims contributor or token generation logic can detect the BankID login context during the external login callback. You may need to persist a flag or use the authentication properties to pass context between the external login initiation and callback, so you can add the correct claim in a single flow.

  The key is to ensure your claims contributor has enough context to know the login was via BankID during the external login callback, so you can add the "BankID-authenticated" claim immediately.

The error "Specified module 'app' does not exist" occurs because the Angular CLI cannot find a module named app when you use the --module app option. In Angular, the --module option expects the name of an existing module file (e.g., app.module.ts), not just app.

Solution

1. Use the Correct Module Path
   • Instead of --module app, specify the full path to your root module file, usually app.module.ts:

yarn ng generate module author --module src/app/app.module.ts --routing --route authors

• This tells Angular CLI to import the new module into src/app/app.module.ts.

2. Verify Module File Exists

   • Ensure that src/app/app.module.ts exists in your project. If your main module has a different name or location, adjust the path accordingly.

3. Reference from Official Tutorial

   • The official ABP Book Store tutorial uses the following command:

yarn ng generate module author --module app --routing --route authors

• However, if your project structure is different or the CLI cannot resolve app, always use the explicit path as shown above.

Example

yarn ng generate module author --module src/app/app.module.ts --routing --route authors

This will correctly generate the author module and update your app.module.ts with the new import.

• ABP Framework 默认支持 OAuth2 的 client_credentials 授权方式。第三方系统可通过 POST 请求调用 /connect/token 接口获取 token。
• 请求示例（以 Postman 或代码方式）：

POST https://<your-abp-server>/connect/token
Content-Type: application/x-www-form-urlencoded

grant_type=client_credentials
&client_id=abpdemo_App
&client_secret=1q11WE

• 你需要在 ABP 的 AuthServer 或 IdentityServer 客户端配置中，确保 client_id、client_secret、允许的 grant_type（client_credentials）已正确设置。

• 系统自带 /connect/token 接口，无需自定义。

• 参考配置和调用方式详见下方链接。

• ABP'nin ticari NuGet paketlerine erişim için, NuGet kaynağınızı (https://nuget.abp.io/{ORGANIZATION_ID}/v3/index.json) kullanırken kullanıcı adı olarak e-posta adresinizi, şifre olarak ise ABP Commercial lisans portalından oluşturduğunuz access token'ı kullanmalısınız.
• Docker build sırasında bu bilgileri güvenli şekilde iletmelisiniz. ARG veya ENV ile şifre göndermek güvenli değildir, bunun yerine Docker build secret veya CI/CD ortam değişkenleri kullanmanız önerilir.
• Ayrıca, "Project file does not exist" hatası, NuGet erişiminden bağımsız olarak Docker context'inizde ilgili .csproj dosyasının bulunmadığını gösterir. Dosya yolunu ve Dockerfile COPY adımlarınızı kontrol edin.

Bu yaklaşım ABP Commercial NuGet erişim standartlarıyla uyumludur, ancak resmi dokümantasyonda Docker build için özel bir örnek bulunmamaktadır.

To reset the distributed cache related to permissions (or any ABP module) after updating permission grants in the database, you need to clear the relevant cache entries. ABP caches permission grants for performance, especially when using Redis as a distributed cache. If you update permissions directly in the database (e.g., via repository), the cache will not be automatically invalidated, and users may not see updated permissions until the cache expires or is cleared.

For the permission system, you should clear the permission grant cache for the affected user/tenant. There is no built-in ABP API to clear only one module's cache, but you can use the IDistributedCache interface to remove specific cache keys.

Example: Clear permission grant cache for a user

using Volo.Abp.Caching;
using Volo.Abp.Authorization.Permissions;
using Microsoft.Extensions.Caching.Distributed;

// Inject IDistributedCache<PermissionGrantCacheItem>
private readonly IDistributedCache<PermissionGrantCacheItem> _permissionGrantCache;

public async Task ClearPermissionGrantCacheAsync(string providerName, string providerKey, string permissionName, Guid? tenantId)
{
    var cacheKey = PermissionGrantCacheItem.CalculateCacheKey(permissionName, providerName, providerKey, tenantId);
    await _permissionGrantCache.RemoveAsync(cacheKey);
}

• providerName: "U" for user, "R" for role
• providerKey: userId.ToString() or roleName
• permissionName: the permission name
• tenantId: the tenant's ID

Call this method after you update the permission grants in the database.

For other modules, you can use the same approach: identify the cache key and remove it using IDistributedCache.

Note: If you want to clear all permission grants cache, you may need to clear all related keys in Redis, but this is not recommended in production unless necessary.

• The error Could not find file '~/Abp/ApplicationLocalizationScript?cultureName=en' during deployment to Azure is typically caused by missing or misconfigured static files, or by the bundling/minification process not including dynamic endpoints like /Abp/ApplicationLocalizationScript.

• In ABP, /Abp/ApplicationLocalizationScript is a dynamic endpoint, not a physical file. If your deployment or bundling configuration tries to treat it as a static file, it will fail.

How to Fix:

1. Check Bundling Configuration:

   • Ensure you are not adding /Abp/ApplicationLocalizationScript as a static file in your bundle configuration. It should not be included in any AddFiles or similar methods for static bundling.

2. Update Your Layouts:

   • In your Razor layout files (e.g., _Layout.cshtml), use the ABP-provided tag helpers or script includes for localization, not a static file reference.

   Example:

<script src="~/Abp/ApplicationLocalizationScript?cultureName=@CultureInfo.CurrentUICulture.Name"></script>

Do not add this path to any static bundle.

3. Azure Deployment:

   • Make sure your deployment process does not remove or block dynamic endpoints under /Abp/.
   • If you use Azure App Service, ensure that all required runtime files are published and that your web.config (if present) does not rewrite or block /Abp/* routes.

4. Clear Bundling Cache:

   • If you have previously bundled this path as a static file, clear your bundling output and cache, then redeploy.

5. Check for Customizations:

   • If you have customized the ABP theme or layout, review those changes to ensure you are not referencing /Abp/ApplicationLocalizationScript in a way that expects it to be a static file.

Summary:
Remove /Abp/ApplicationLocalizationScript from any static bundle configuration. Reference it only as a dynamic script in your layout. Redeploy after clearing any old bundle outputs.

• The impersonation ("Login with this tenant") and return icon issues in ABP Blazor WebApp (v9.3, LeptonX, non-tiered, multi-tenancy) are known and have been reported by other users. The problems include:

  • The impersonation menu option is inconsistently visible.
  • When impersonation works, a NullReferenceException is thrown (see stack trace), but after a refresh, the impersonation session appears to work temporarily.
  • The "return" icon for ending impersonation disappears after a short time.

• These issues are not present in Blazor Server starter templates, only in Blazor WebApp projects generated by ABP Suite.

• The root cause is related to the ABP Unit of Work and transaction behavior in the Blazor WebApp template, especially after package upgrades (9.2 → 9.3). The impersonation state is not reliably maintained, and the UI does not always reflect the correct session.

Recommended Actions:

1. Ensure all ABP and module packages are updated to the latest compatible versions (including LeptonX and SaaS modules).
2. Clean and rebuild the solution after upgrading packages.
3. If the problem persists, this is a framework-level issue. You should report it (if not already) or follow the official support thread for updates:
   • ABP Support: Blazor Web App Impersonation Issue

Workaround:

• As a temporary measure, use the Blazor Server template if impersonation is critical for your workflow, as it does not exhibit these issues.

• The error NG01203: No value accessor for form control name: 'authorId' in your ABP Suite-generated Angular UI typically means the form control is not bound to a compatible Angular Material component (like <mat-select>) or the necessary module is not imported.

• In a one-to-many navigation (e.g., Book → Author), ABP Suite should generate a dropdown for selecting the related entity (Author) in both the create/edit form and the advanced filter. If this is missing, it is usually due to:

  1. The <mat-select> component is not used for the authorId field.
  2. The MatSelectModule is not imported in your feature or shared module.
  3. The lookup data for authors is not loaded or bound to the dropdown.

How to Fix:

1. Ensure <mat-select> is used for authorId:

<mat-form-field>
     <mat-label>Author</mat-label>
     <mat-select formControlName="authorId" required>
       <mat-option *ngFor="let author of authors" [value]="author.id">
         {{ author.name }}
       </mat-option>
     </mat-select>
   </mat-form-field>

2. Import MatSelectModule in your module:

import { MatSelectModule } from '@angular/material/select';

   @NgModule({
     imports: [
       // ... other imports
       MatSelectModule
     ]
   })
   export class SharedModule { }

3. Load and bind the authors list: In your component:

authors: AuthorDto[] = [];

   ngOnInit() {
     this.authorService.getList().subscribe(result => {
       this.authors = result.items;
     });
   }

4. Advanced Filter Dropdown: Similarly, use <mat-select> for the filter and bind the authors list.

5. Regenerate Code if Needed: If the ABP Suite did not generate the dropdown, you may need to re-add the navigation property and regenerate, ensuring you select the correct display and filter options.

This approach aligns with common ABP conventions for one-to-many navigation properties in Angular UI.

To resolve the issue with missing AI library static assets (such as dompurify) in a module-based ABP application, especially when the AI chat page is in a submodule, follow these steps:

1. Ensure the required JS libraries (e.g., dompurify, marked, etc.) are present in your project:

   • Place the necessary files (like /ai-libs/dompurify/dist/purify.es.mjs) in the wwwroot/ai-libs directory of the module or the main web project.
   • If your submodule is a class library, ensure it has a wwwroot folder and that the files are marked as "Content" and "Copy if newer" in the .csproj.

2. Serve static files from the submodule:

   • In your submodule's module class, add the following configuration to ensure embedded/static files are served:

Configure<AbpVirtualFileSystemOptions>(options =>
   {
       options.FileSets.AddEmbedded<YourSubmoduleName>();
   });

   Configure<AbpAspNetCoreStaticFilesOptions>(options =>
   {
       options.FileSets.AddEmbedded<YourSubmoduleName>();
   });

Replace YourSubmoduleName with the actual module class.

3. If using embedded resources, ensure the files are embedded:
   • In your .csproj:

<ItemGroup>
       <EmbeddedResource Include="wwwroot\**" />
     </ItemGroup>

4. If using physical files, ensure the StaticFiles middleware is enabled in your main app's Startup or Program:

app.UseStaticFiles();

5. Reference the static assets correctly in your page/component:

   • Use /ai-libs/dompurify/dist/purify.es.mjs as the path if the files are in the main web project's wwwroot.
   • If served from a module, the path may be /Your.Module.Name/ai-libs/dompurify/dist/purify.es.mjs.

6. Publish and verify:

   • After publishing, check that the files are present in the output directory and accessible via the expected URLs.

This approach ensures that static assets required by the AI chat template are available at runtime, regardless of whether the page is in the main app or a submodule.
