Hi,

My requirement is similar to this ticket : https://support.abp.io/QA/Questions/1087/DbMigrator-for-multi-tenant--multi-db

But I can't see any resolution on this ticket. Please can you help me with it.

Also If you can answer below question it will be helpful

  1. This is the end point api/saas/tenants/3a03440a-5d0e-e4e2-4fa5-c40c2671b8fe/apply-database-migrations. I was not able to find the actual app service method it belongs to on git hub, please give me the name of this app service.
  2. Will I be able to override the above service ?
  3. How do I add multiple connection string ( i,e, per module ) from UI i.e. Saas Tenant screen where we create a Tenant and give the connection string. My project have 3 custom module, So I have 1 database for Admin/Abp/IdentityServer and other 3 for 3 different modules

    If the default UI does not support it, you need to implement it yourself. Custom the app service and Angular UI

    I suggest you download the source code of the saas module for analysis.

    If your change too much, you can add the source code of saas to your project.

    Hello

    You need to replace TenantsComponent and TenantService.

    You can replace TenantComponent with the following code

    import {Component} from '@angular/core';
    import {ReplaceableComponentsService} from "@abp/ng.core";
    import {eSaasComponents} from "@volo/abp.ng.saas";
    
    @Component({
    /* Component Metadata */
    })
    export class AppComponent {
      constructor(private replaceableComponentsService: ReplaceableComponentsService) {
        replaceableComponentsService.add({
          key: eSaasComponents.Tenants,
          component: YOUR_COMPONENT
        });
      }
    }
    

    And you can replace TenantService with the following code

    //app.module.ts
    
    import {NgModule} from '@angular/core';
    import {MyTenantService} from "./my-tenant.service";
    import {TenantService} from "@volo/abp.ng.saas";
    
    @NgModule({
      declarations: [
      //declarations
      ],
      imports: [
        // imports
      ],
      providers: [
        // other providers
        {
          provide: TenantService,
          useClass: MyTenantService
        }
      ]
    })
    export class AppModule {}
    

    Also, you can replace only the ConnectionStringsComponent in version 4.4 and abp supports multiple connection strings in version 4.4

    If you upgrade your version to 4.4 you can replace ConnectionStringsComponent with the following code

    import {Component} from '@angular/core';
    import {ReplaceableComponentsService} from "@abp/ng.core";
    import {eSaasComponents} from "@volo/abp.ng.saas";
    
    @Component({
    /* Component Metadata */
    })
    export class AppComponent {
      constructor(private replaceableComponentsService: ReplaceableComponentsService) {
        replaceableComponentsService.add({
          key: eSaasComponents.ConnectionStrings,
          component: YOUR_COMPONENT
        });
      }
    }
