Second Context Problem #2906


User avatar

mpm created

I'm having a few issues getting a second context to a vended app database wired up properly (second context should not use code first). The specific error I am getting when attempting to run 'abp.services.app.vended.getAttributes()' is 'error detail not sent by server', with a response of '{"message":"An error has occurred."}'.

I've looked at the MultiContextDemo app, and think I have things wired up properly, but I am obviously missing something.

CSDataModule

[DependsOn(typeof(AbpZeroEntityFrameworkModule), typeof(CSCoreModule))]
    public class CSDataModule : AbpModule
    {
        public override void PreInitialize()
        {
            Database.SetInitializer(new CreateDatabaseIfNotExists<CSDbContext>());
            
            //web.config (or app.config for non-web projects) file should contain a connection string named "Default".
            Configuration.DefaultNameOrConnectionString = "Default";
        }

        public override void Initialize()
        {
            IocManager.RegisterAssemblyByConvention(Assembly.GetExecutingAssembly());
            Database.SetInitializer<VendedDbContext>(null);
        }
    }

VendedDbContext

public class VendedDbContext : AbpDbContext
    {
        public VendedDbContext()
            : base("Vended")
        {
            
        }
    }

Attribute Class

using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;
using Abp.Domain.Entities;

namespace MCMT.CS.Vended
{
   /// <summary>
    /// A class which represents the Attribute table.
    /// </summary>
	[Table("Attribute")]
    public class Attribute : Entity
    {
        [Key]
        public virtual int AttributeID { get; set; }
        public virtual int ResourceTypeID { get; set; }
        public virtual string Name { get; set; }
        public virtual int AttributeTypeID { get; set; }
        public virtual int? SortOrder { get; set; }
        public virtual string DefaultValue { get; set; }
        public virtual byte? ResNameIndex { get; set; }
        public virtual bool IsUnique { get; set; }
        public virtual byte? RepNameIndex { get; set; }
        public virtual string RepNameFormat { get; set; }
        public virtual bool IsCertification { get; set; }
        public virtual bool IsPublic { get; set; }
        public virtual int? SpecialTypeID { get; set; }
        public virtual bool ShowOnTimesheet { get; set; }
        public virtual bool IsSelfServe { get; set; }
        public virtual string CertType { get; set; }
        public virtual int? CertWarnDays { get; set; }
        public virtual int? CertExpireDays { get; set; }
        public virtual string CertExpireValue { get; set; }
        public virtual bool IsContact { get; set; }
        public virtual int? CertValueOperator { get; set; }
        public virtual bool CertIgnoreNull { get; set; }
        public virtual bool CertForbidPunch { get; set; }
    }
}

Vended App Service Interface

using System.Collections.Generic;
using Abp.Application.Services;

namespace MCMT.CS.Vended
{
    public interface IVendedAppService : IApplicationService
    {
        List<Attribute> GetAttributes();
    }
}

Vended App Service

using System.Collections.Generic;
using System.Linq;
using Abp.Auditing;
using Abp.Domain.Repositories;

namespace MCMT.CS.Vended
{
    [DisableAuditing]
    public class VendedAppService : CSAppServiceBase, IVendedAppService
    {
        private readonly IRepository<Attribute> _aRepository;
        
        public VendedAppService(IRepository<Attribute> aRepository)
        {
            _aRepository = aRepository;
        }

        public List<Attribute> GetAttributes()
        {
            var attributes = _aRepository.GetAllList().ToList();
            return attributes;
        }
    }
}

Any assistance would be appreciated.

    Hi,

    Your usage seems correct. Can you check Logs.txt file under your Web project. It might contain detailed error message.

    Thanks.

    This turned out to be a dumb mistake on my part. I forgot to define an IDbSet for each entity in my second database context. :roll:

    Working flawlessly now!
