Where is the override keyword?

This is the code from Saas Module

[Authorize(SaasHostPermissions.Tenants.ManageConnectionStrings)]
        public async Task ApplyDatabaseMigrationsAsync(Guid id)
        {
            await DistributedEventBus.PublishAsync(
                new ApplyDatabaseMigrationsEto
                {
                    TenantId = id,
                    DatabaseName = ConnectionStrings.DefaultConnectionStringName
                }
            );
            
            foreach (var databaseInfo in DbConnectionOptions.Databases.Values)
            {
                if (!databaseInfo.IsUsedByTenants)
                {
                    continue;
                }
                
                await DistributedEventBus.PublishAsync(
                    new ApplyDatabaseMigrationsEto
                    {
                        TenantId = id,
                        DatabaseName = databaseInfo.DatabaseName
                    }
                );    
            }
        }

ApplyDatabaseMigrationsAsync method is not virtual so we cannot override it

Hi,

                {
                    TenantId = id,
                    DatabaseName = ConnectionStrings.DefaultConnectionStringName
                }
            );

            foreach (var databaseInfo in DbConnectionOptions.Databases.Values)
            {
                if (!databaseInfo.IsUsedByTenants)
                {
                    continue;
                }

                await DistributedEventBus.PublishAsync(
                    new ApplyDatabaseMigrationsEto
                    {
                        TenantId = id,
                        DatabaseName = databaseInfo.DatabaseName
                    }
                );
            }
        }
    }
}

My swagger is showing error now as below :

Also If you can give advice me on adding 3 new string properties in SaasTenantCreateDto which I want to Insert into SaasTenantConnectionStrings table.

Please answer both of my queries. Thanks !!!

Hi mailming

This is TenantAppService source code https://github.com/abpframework/abp/blob/4.3.1/modules/tenant-management/src/Volo.Abp.TenantManagement.Application/Volo/Abp/TenantManagement/TenantAppService.cs

There are no events published here Also there is no method called ApplyDatabaseMigrations in this AppService.

Please can you guide us with sample code or something as this activity is on priority for us.

Hi still not working with ITransientDependency

Hi **@maliming **

How do I Custom the app service and Angular UI I need few details : Angular

• Component I need to override
• How do I add field or list of connection string to DTO

Service level

• Which method in TenantAppService I need to override as none of the method in TenantAppService is with name ApplyDatabaseMigrations
• How do I add extra properties for modules connection strings in abp's DTO

Hi @enisn,

Can't we use TenantSettingValueProvider ? This is also a kind of setting manager right ?

Is there any answer for this question ?

@albert Please reply.

I was able to validate user credentitals using await _signInManager.CheckPasswordSignInAsync() Now I just want to know below things, This is angular login component code

login(params: LoginParams): Observable<any>; Which backend method is called when the above method is called from angular component ?

May be I can make a wrapper method and call this backend login method in my method once I done with my requirement.

import { Injector } from '@angular/core';
import { Params } from '@angular/router';
import { Observable } from 'rxjs';
import { LoginParams } from '../strategies/auth-flow.strategy';
import * as ɵngcc0 from '@angular/core';
export declare class AuthService {
    protected injector: Injector;
    private strategy;
    get isInternalAuth(): boolean;
    constructor(injector: Injector);
    init(): Promise<any>;
    logout(queryParams?: Params): Observable<any>;
    /**
     * @deprecated Use navigateToLogin method instead. To be deleted in v5.0
     */
    initLogin(): void;
    navigateToLogin(queryParams?: Params): void;
    login(params: LoginParams): Observable<any>;
    static ɵfac: ɵngcc0.ɵɵFactoryDef<AuthService, never>;
}

Can you share a simple project?

No I can't.Sorry May be we can have a section and you can have a look into my project.
