I want to extend BasicRepositoryBase to add a new function for all my repositories.
I created my interface as follows
using System;
using System.Threading.Tasks;
using Volo.Abp.Domain.Entities;
using Volo.Abp.Domain.Repositories;
namespace FMS.Domain.Repositories
{
public interface IFMSRepository<TEntity, TKey> : IBasicRepository<TEntity,TKey>, IRepository<TEntity, TKey>
where TEntity : class, IEntity<TKey>
{
Task<TEntity> CreateOrUpdate(TEntity entity);
}
}
I created my repository as follows. I added a new function CreateOrUpdate.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Linq.Expressions;
using System.Threading;
using System.Threading.Tasks;
using Volo.Abp.DependencyInjection;
using Volo.Abp.Domain.Entities;
using Volo.Abp.Domain.Repositories;
using Volo.Abp.Identity;
namespace FMS.Domain.Repositories
{
public abstract class FMSRepository<TEntity, TKey> : BasicRepositoryBase<TEntity, TKey>, IFMSRepository<TEntity, TKey>
where TEntity : class, IEntity<TKey>
{
public async Task<TEntity> CreateOrUpdate(TEntity entity )
{
TEntity resultEntity;
if (entity.Id == null)
{
resultEntity = await InsertAsync(entity);
}
else
{
var checkEntity = await GetAsync(entity.Id);
if (checkEntity != null)
resultEntity = await UpdateAsync(entity);
else
resultEntity = await InsertAsync(entity);
}
return resultEntity;
}
public abstract Task DeleteAsync(Expression<Func<TEntity, bool>> predicate, bool autoSave = false, CancellationToken cancellationToken = default);
public abstract Task DeleteDirectAsync(Expression<Func<TEntity, bool>> predicate, CancellationToken cancellationToken = default);
public abstract Task<TEntity> FindAsync(Expression<Func<TEntity, bool>> predicate, bool includeDetails = true, CancellationToken cancellationToken = default);
public abstract Task<TEntity> GetAsync(Expression<Func<TEntity, bool>> predicate, bool includeDetails = true, CancellationToken cancellationToken = default);
public abstract Task<IQueryable<TEntity>> GetQueryableAsync();
public abstract IQueryable<TEntity> WithDetails();
public abstract IQueryable<TEntity> WithDetails(params Expression<Func<TEntity, object>>[] propertySelectors);
public abstract Task<IQueryable<TEntity>> WithDetailsAsync();
public abstract Task<IQueryable<TEntity>> WithDetailsAsync(params Expression<Func<TEntity, object>>[] propertySelectors);
}
}
To register new repository I tried two different approaches in ApplicationModule File
first approach
public override void ConfigureServices(ServiceConfigurationContext context)
{
Configure<AbpAutoMapperOptions>(options =>
{
options.AddMaps<FMSApplicationModule>();
});
context.Services.AddScoped(typeof(IFMSRepository<,>), typeof(FMSRepository<,>));
}
Second approach
public override void ConfigureServices(ServiceConfigurationContext context)
{
Configure<AbpAutoMapperOptions>(options =>
{
options.AddMaps<FMSApplicationModule>();
});
System.Reflection.Assembly.GetExecutingAssembly()
.GetTypes()
.Where(item => item.GetInterfaces()
.Where(i => i.IsGenericType).Any(i => i.GetGenericTypeDefinition() == typeof(IFMSRepository<,>)) && !item.IsAbstract && !item.IsInterface)
.ToList()
.ForEach(assignedTypes =>
{
var serviceType = assignedTypes.GetInterfaces().First(i => i.GetGenericTypeDefinition() == typeof(IFMSRepository<,>));
context.Services.AddScoped(serviceType, assignedTypes);
});
}
Both option yield the same error in my data seeder class which I use the new repository method. Below is my data seeder class
using System;
using System.Threading.Tasks;
using FMS.Domain.Repositories;
using FMS.Fairs;
using Volo.Abp.Data;
using Volo.Abp.DependencyInjection;
using Volo.Abp.Domain.Repositories;
using Volo.Abp.MultiTenancy;
namespace FMS.DataSeed
{
public class FMSDataSeederContributer
: IDataSeedContributor, ITransientDependency
{
private readonly IFMSRepository<FairArea, Guid> _fairAreaRepository;
private readonly ICurrentTenant _currentTenant;
public FMSDataSeederContributer(
IFMSRepository<FairArea,Guid> fairAreaRepository,
ICurrentTenant currentTenant)
{
_fairAreaRepository = fairAreaRepository;
_currentTenant = currentTenant;
}
public async Task SeedAsync(DataSeedContext context)
{
using (_currentTenant.Change(context?.TenantId))
{
if (context?.TenantId == null)
{
return;
}
if (await _fairAreaRepository.GetCountAsync() > 0)
{
return;
}
await _fairAreaRepository.CreateOrUpdate(
new FairArea
{
Name = "Name of Area",
Type = FairAreaType.ClosedArea,
Description = "Description of Area",
Address = "Country of Area",
TenantId = _currentTenant.Id
}
) ;
}
}
}
}
Here is the DataSeeder program output.

Any help is appreciated.
You are trying to register an abstract class, instead you need to register a concrete class. You can inherit from the EfCoreRepository class. Or in an easier way, you can write it as an extensions method.
