Migrations Error unable to create object of type #1782

pvaz created 3 years ago

ABP Framework version: v4.4.0
UI type: MVC
DB provider: EF Core
Tiered (MVC) or Identity Server Separated (Angular): yes
Exception message and stack trace:
Steps to reproduce the issue:"

When I'm trying to add a new migration using the command line dotnet ef migrations add TicketStatuses I get the following error:

Unable to create an object of type 'IndoDbContext'. For the different patterns supported at design time, see https://go.microsoft.com/fwlink/?linkid=851728

I have all well defined on the frameworkcore

namespace Indo.TicketStatus { public class EfCoreTicketStatusRepository : EfCoreRepository<IndoDbContext, TicketStatuses, Guid>, ITicketStatusRepository { public EfCoreTicketStatusRepository( IDbContextProvider<IndoDbContext> dbContextProvider) : base(dbContextProvider) { } } }

What's missing ?

Can you share the steps to reproduce the problem with a new project?

Hi,

I think it's better to share the project with you, so you can test easier and for sure spot the problem quickier

Share the steps will be simpler.

Well, not so easier, but ok.

I've create the following files in the following projects/folders:

Project.Domain
- TicketStatuses
  - ITicketStatusRepository.cs
  - TicketStatus.cs
  - TicketStatusAlreadyExistsException.cs
  - TicketStatusManager.cs
Project.Domain.Shared
- TicketStatuses
  - TicketStatusConsts.cs
Project.EntityFrameworkCore
- EfCoreTicketStatusRepository.cs
Project.Application
- TicketStatuses
  - TicketStatusesAppService.cs
Project.Application.Contracts
- TicketStatuses
  - CreateTicketStatusDto.cs
  - ITicketStatusAppService.cs
  - TicketStatusDto.cs
  - UpdateTicketStatusDto.cs

In Project.Application on file ProjectApplicationAutoMapperProfile.cs I've added

CreateMap<TicketStatus, TicketStatusDto>()

In Project.EntityFrameworkCore -> EntityFrameworkCore - IndoDbContext.cs - public DbSet<TicketStatus> TicketStatuses { get; set; }

IndoDbContextModelCreatingExtensions builder.Entity<TicketStatus>(b => { b.ToTable(IndoConsts.DbTablePrefix + "TicketStatuses", IndoConsts.DbSchema); b.ConfigureByConvention(); b.Property(x => x.Description).HasColumnName(nameof(TicketStatus.Description)).IsRequired(); b.Property(x => x.CloseTicket).HasColumnName(nameof(TicketStatus.CloseTicket)); });

Project is compiling without any error.

The I went to the command shell, Project.EntityFrameworkCore, and done the following command

dotnet ef migrations add Added_TicketStatuses

There is should be a IndoDbContextFactory.cs file and Microsoft.EntityFrameworkCore.Tools package in hte EntityFrameworkCore project.

/* This class is needed for EF Core console commands
 * (like Add-Migration and Update-Database commands) */
public class IndoDbContextFactory : IDesignTimeDbContextFactory<IndoDbContext>
{
    public IndoDbContext CreateDbContext(string[] args)
    {
        IndoEfCoreEntityExtensionMappings.Configure();

        var configuration = BuildConfiguration();

        var builder = new DbContextOptionsBuilder<IndoDbContext>()
            .UseSqlServer(configuration.GetConnectionString("Default"));

        return new IndoDbContext(builder.Options);
    }

    private static IConfigurationRoot BuildConfiguration()
    {
        var builder = new ConfigurationBuilder()
            .SetBasePath(Path.Combine(Directory.GetCurrentDirectory(), "../Indo.DbMigrator/"))
            .AddJsonFile("appsettings.json", optional: false);

        return builder.Build();
    }
}
