AutoMapper с EF6, не заполняющим один из отображаемых объектов

У меня есть приложение EF6 MVC с использованием кода First для генерации моделей. Я пытаюсь создать сопоставление с использованием AutoMapper между моделью и представлением viewmodel этой модели.AutoMapper с EF6, не заполняющим один из отображаемых объектов

У меня нет ошибок, но в результирующем объекте отсутствуют детали для объекта PTCredential. В частности, мне не хватает объекта PTCredential, который вложен в PTCredential. Я не верю, что Игнорирование вызывает это, но я не могу его закрепить. Я пробовал некоторые предложения из других сообщений в AutoMapper, но ничего не оказалось полезным.

Может ли кто-нибудь помочь в том, что я могу сделать, чтобы успешно использовать AutoMapper в этой ситуации?

Вот код, как я настройке и инициализации Mapper:

var pTConnections = _db.PTConnections.Include(p => p.PTConnectionClass).ToList(); 

     Mapper.Initialize(cfg => 
     { 
      cfg.CreateMap<PTConnection, PTConnectionViewModel>() 
       .AfterMap((s, d) => { foreach (var i in d.PTCredentialAssignments) i.PTConnection = d; }); 

      cfg.CreateMap<PTCredentialAssignment, PTCredentialAssignmentViewModel>() 
       .ForMember(m => m.PTCredential, opt => opt.Ignore()) 
       .ForMember(m => m.PTConnection, opt => opt.Ignore()); 

      cfg.CreateMap<PTVendor, PTVendorViewModel>() 
       .ForMember(m => m.PTCredentials, opt => opt.Ignore()) 
       .ForMember(m => m.PTConnections, opt => opt.Ignore()); 

      cfg.CreateMap<PTCredential, PTCredentialViewModel>(); 

      cfg.CreateMap<PTConnectionClass, PTConnectionClassViewModel>() 
       .ForMember(m => m.PTConnections, opt => opt.Ignore()); 

      cfg.CreateMap<PTConnectionContactAssignment, PTConnectionContactAssignmentViewModel>() 
       .ForMember(m => m.PTConnection, opt => opt.Ignore()); 

     }); 

    var dest = Mapper.Map<List<PTConnection>, List<PTConnectionViewModel>>(pTConnections);

Я не знаком с automapper ... однако, где вы включаете свойство навигации? с обычными вызовами DbSet это свойство должно быть нулевым, пока не будет перечислено, или соответствующий объект уже находится в контексте. – DevilSuichiro

«В частности, я пропускаю объект PTCredential, который вложен в PTCredential» - это опечатка? Если вам не хватает его из PTCredentialAssignmentViewModel, тогда да, вы говорите ему, чтобы игнорировать это. –

@ Steve-Greene Спасибо за ваше предложение, иногда вы не можете увидеть лес через деревья, и вот что здесь произошло. Мне показалось, что я прошел через мою модель данных так хорошо, как только разместил, но, когда вы указали мою опечатку, я вернулся и смог увидеть, чего не хватает. Я заметил, что одним из моих других объектов было сопоставление, заставляя меня делать правильное сопоставление и получать правильный объект. Спасибо за вашу помощь! – silverbullettruck2001

Вот картинка, которая сделала мое решение:

 cfg.CreateMap<PTConnection, PTConnectionViewModel>() 
      .AfterMap((s, d) => { foreach (var i in d.PTCredentialAssignments) i.PTConnection = d; }); 

     cfg.CreateMap<PTCredentialAssignment, PTCredentialAssignmentViewModel>() 
      .ForMember(m => m.PTConnection, opt => opt.Ignore()); 

     cfg.CreateMap<PTVendor, PTVendorViewModel>() 
      .ForMember(m => m.PTCredentials, opt => opt.Ignore()) 
      .ForMember(m => m.PTConnections, opt => opt.Ignore()); 

     cfg.CreateMap<PTCredential, PTCredentialViewModel>() 
      .ForMember(m => m.PTCredentialAssignments, opt => opt.Ignore()) 
      .ForMember(m => m.PTCredentialContactAssignments, opt => opt.Ignore()); 

     cfg.CreateMap<PTConnectionClass, PTConnectionClassViewModel>() 
      .ForMember(m => m.PTConnections, opt => opt.Ignore()); 

     cfg.CreateMap<PTConnectionContactAssignment, PTConnectionContactAssignmentViewModel>() 
      .ForMember(m => m.PTConnection, opt => opt.Ignore());
