Error when using GetAll (AsyncCrudAppService) and apply sorting - asp.net-core

Question

I've built an application service based on the AsyncCrudAppService class, like this:
public class ServiceTemplateAppService : AsyncCrudAppService<ServiceTemplate, ServiceTemplateDto, int, PagedAndSortedResultRequestDto, CreateServiceTemplateDto, UpdateServiceTemplateDto>, IServiceTemplateAppService
Everything works as intended, but once in a while I get an error when calling the GetAll method and passing in a sorting parameter, like this:
api/services/app/CostCenter/GetAll?SkipCount=0&MaxResultCount=10&Sorting=displayName%20asc
I have overridden the CreateFilteredQuery method and it now looks like this because I want to get some child entities.
protected override IQueryable<ServiceTemplate> CreateFilteredQuery(PagedAndSortedResultRequestDto input)
{
return Repository.GetAll()
.Include(x => x.ServiceTemplateRole)
.ThenInclude(y => y.Role)
.Include(x => x.ServiceTemplateImage)
.Include(x => x.ServiceTemplateCategory);
}
The error message that I get is this one:

I've tried to figure out what could cause the problem and adding the assembly that the exceptions tells me, but no progress. The strange thing is that this sometimes work, so my guess is that is has something to do with the actual data in the DB, but hey?! I don't know...

Answer 1

GetAll Method From AsyncCrudAppService calls ApplySorting Method, you can override it and there sort as you want.
protected override IQueryable<YourEntity> ApplySorting(IQueryable<YourEntity> query, PagedAndSortedResultRequestDto input)
{
if (input.Sorting.IsNullOrEmpty())
{
input.Sorting = "yourColumn asc";
}
return base.ApplySorting(query, input);
}
If you want to crate another GetAll Method here is an example:
public Task<PagedResultDto<PaisDto>> GetAllFiltered(PagedAndSortedResultRequestDto input, string filter)
{
var paisList = new List<Pais>();
var query = Repository.GetAll();
query = ApplySorting(query, input);
if (filter != null && filter != string.Empty)
{
paisList = query
.Where(x => x.Identificador.StartsWith(filter) || x.Nombre.StartsWith(filter))
.Skip(input.SkipCount)
.Take(input.MaxResultCount).ToList();
var result = new PagedResultDto<PaisDto>(query.Count(), ObjectMapper.Map<List<PaisDto>>(paisList));
return Task.FromResult(result);
}
else
{
paisList = query
.Skip(input.SkipCount)
.Take(input.MaxResultCount).ToList()
.ToList();
var result = new PagedResultDto<PaisDto>(query.Count(), ObjectMapper.Map<List<PaisDto>>(paisList));
return Task.FromResult(result);
}
}
query = ApplySorting(query, input); in this line you can call base method base.ApplySorting(query, input);
