1. Add-Migration "HostMigration" -Context MVCTierdSepSchemaDbContext
2. Then I run dbmigrator and receive the error message
3. Add-Migration "TenantMigration" -Context MVCTierdSepSchemaTenantDbContext -OutputDir TenantMigrations
4. Then I run dbmigrator and receive the error message

i have yes and while it creates the schema it fails on seeding the data. i get the same error message regardless.

H Cotur,

Can you detail out what the bug was? I'm using this project as an example of how to implement things in my project so I want to make sure this bug won't affect my project.

Thanks.

• Steps to reproduce the issue: using ABP suite I creat new solution. MVC, DB PostgreSQL, Seperated tenant schema with tiered option. I manually add the first migration (because there are 2 contexts in the dbmigrator project) and then run the dbmigrator project to apply the migration and seed the data. I get the above message.

In my OnModelCreating method of the *DbContextBase.cs file I have the following code to remove the 'abp' prefix from the table names.

protected override void OnModelCreating(ModelBuilder builder)
{
    base.OnModelCreating(builder);

    /* Include modules to your migration db context */

    builder.ConfigurePermissionManagement(options => { options.TablePrefix = ""; });
    builder.ConfigureSettingManagement(options => { options.TablePrefix = ""; });
    builder.ConfigureBackgroundJobs(options => { options.TablePrefix = ""; });
    builder.ConfigureAuditLogging(options => { options.TablePrefix = ""; });
    builder.ConfigureIdentityPro(options => { options.TablePrefix = ""; });
    builder.ConfigureIdentityServer(options => { options.TablePrefix = ""; });
    builder.ConfigureFeatureManagement(options => { options.TablePrefix = ""; });
    builder.ConfigureLanguageManagement(options => { options.TablePrefix = ""; });
    builder.ConfigureSaas(options => { options.TablePrefix = ""; });
    builder.ConfigureTextTemplateManagement(options => { options.TablePrefix = ""; });
    builder.ConfigureBlobStoring(options => { options.TablePrefix = ""; });

    /* Configure your own tables/entities inside here */

    //builder.Entity<YourEntity>(b =>
    //{
    //    b.ToTable(MVCTierdSepSchemaConsts.DbTablePrefix + "YourEntities", MVCTierdSepSchemaConsts.DbSchema);
    //    b.ConfigureByConvention(); //auto configure for the base class props
    //    //...
    //});

    //if (builder.IsHostDatabase())
    //{
    //    /* Tip: Configure mappings like that for the entities only available in the host side,
    //     * but should not be in the tenant databases. */
    //}
}

Thanks for this. I notice though that the Blazor application does not run. I followed all the steps as outlined in the 'Server Side / MVC' section prior to trying to run the Blazor application and the Blazor app just gives me the spinner in the center of the page as shown in the attachment.

Is there a comprehensive open source or feature rich application (like an ecommerce site) showcasing real world scenarios using ABP? What I'm having a hard time figuring out is how to do the most basic standard web application tasks using ABP and a real-world sample application would be beneficial as a reference for further investigation.

I would like to override the existing layout of the stock theme that comes with ABP. In other words I want to have multiple base layouts that I can set programitically for certain pages, etc. How can this be accomplished?
