マップされたオブジェクトの1つにEF6が挿入されていないAutoMapper

コードファーストを使用してモデルを生成するEF6 MVCアプリケーションがあります。私はモデルとそのモデルのviewmodel表現の間でAutoMapperを使用してマッピングを作成しようとしています。マップされたオブジェクトの1つにEF6が挿入されていないAutoMapper

私はエラーはありませんが、結果オブジェクトにPTCredentialオブジェクトの詳細がありません。具体的には、PTCredential内にネストされたPTCredentialオブジェクトがありません。私は無視がこれを引き起こしているとは思わないが、私はそれを固定することはできない。私はAutoMapperの他の投稿からいくつかの提案を試みましたが、何も有用であるとは証明されていません。

誰でも私がこの状況でAutoMapperをうまく使用するためにできることをいくつか助けてくれますか？ここで

は私がマッパーを設定し、初期化していますどのようにするコードです：ここで

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);

私はautomapperに慣れていません...しかし、あなたはナビゲーションプロパティをどこに入れますか？通常のDbSet呼び出しでは、このプロパティは列挙されるか、対応するエンティティがすでにコンテキストに入るまでnullにする必要があります。 – DevilSuichiro

「特にPTCredential内にネストされたPTCredentialオブジェクトがありません」 - これは誤字ですか？ PTCredentialAssignmentViewModelからPTCredentialAssignmentViewModelを紛失した場合は、それを無視するように指示します。 –

@ Steve-Greeneあなたの提案をお寄せいただきありがとうございます、時々あなたは木々の中で森を見ることができません。投稿前にデータモデルをよく調べていたと思っていましたが、誤植を指摘したときに私は戻ってきて、私が見逃していたものを見ることができました。私は他のオブジェクトの1つがマッピングであることに気付いて、正しいマッピングを実行して正しいオブジェクトを取得しないようにしていました。ご協力いただきありがとうございます！ – silverbullettruck2001

私の解決策を作ったマッピングは次のとおりです：

 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());
