ObjectMapper List mapping #5539 | Support Center

ice2burn created 6 years ago

Hi,

Trying to map list to my model using ObjectMapper.

public class GetTicketForView
    {
        public TicketDto Ticket { get; set; }
        public string TenantName { get; set; }
        public string ProductName { get; set;}
        public string ProductVersionName { get; set;}
        public TicketStateTableDto TicketState { get; set; }
        public string TicketTypeName { get; set;}
        public string TicketPriorityName { get; set;}
        public List<TicketLinkedUserDto> LinkedUsers { get; set; } // <--
    }

TicketLinkedUsers is many to many relation.

AppService:

. . .
var query = (from o in filteredTickets
             join o1 in _productRepository.GetAll() on o.ProductId equals o1.Id into j1
             from s1 in j1.DefaultIfEmpty()
             join o2 in _productVersionRepository.GetAll() on o.ProductVersionId equals o2.Id into j2
             from s2 in j2.DefaultIfEmpty()
             join o3 in _ticketTypeRepository.GetAll() on o.TicketTypeId equals o3.Id into j3
             from s3 in j3.DefaultIfEmpty()
             join o4 in _ticketPriorityRepository.GetAll() on o.TicketPriorityId equals o4.Id into j4
             from s4 in j4.DefaultIfEmpty()
             join o5 in _ticketStateRepository.GetAll() on o.TicketStateId equals o5.Id into j5
             from s5 in j5.DefaultIfEmpty()
             join o6 in _tenantManager.Tenants on o.TenantId equals o6.Id into j6
             from s6 in j6.DefaultIfEmpty()
             join o7 in _ticketLinkedUsersRepository.GetAll() on o.Id equals o7.TicketId into j7
             from s7 in j7.DefaultIfEmpty()
             select new GetTicketForView() { Ticket = ObjectMapper.Map<TicketDto>(o)
        , ProductName = s1 == null ? "" : s1.Name.ToString()
        , ProductVersionName = s2 == null ? "" : s2.Name.ToString()
        , TicketTypeName = s3 == null ? "" : s3.Name.ToString()
        , TicketPriorityName = s4 == null ? "" : s4.Name.ToString()
        , TicketState = ObjectMapper.Map<TicketStateTableDto>(s5)
        , TenantName = s6 == null ? "" : s6.Name.ToString()
        , LinkedUsers = ObjectMapper.Map<List<TicketLinkedUserDto>>(s7) // <--
});

But it fails with:

Unmapped properties: Capacity

s7 is not a List.

You are right, it should be J7.

However I get different error in log:

select refers to an instance in j7. You can't map the whole j7 in a select.

What a pity, it would be so elegant.

Made it with separate query:

foreach (var ticket in tickets)
{
    var linkedUsers = _ticketLinkedUsersRepository.GetAllIncluding(lu => lu.TicketLinkType, lu => lu.User)
        .Where(p => p.TicketId == ticket.Ticket.Id).ToList();
    ticket.LinkedUsers = ObjectMapper.Map<List<TicketLinkedUserDto>>(linkedUsers);
 }

Thanks for your help
