MVC多個數據庫在一個單一的域模型

Question

我正在寫一個基於史蒂夫桑德森的臨Asp.Net MVC框架的應用程序，該應用程序使用數據建模，如該書上體育商店應用程序中所述。我的應用程序運行良好，我使用Castle項目作爲IOC，但我有兩個數據庫。第一個存儲多種數據和我的客戶信息。第二個只存儲每個客戶的醫療數據。我需要創建一個類，在客戶表中返回的數據，位於數據庫1和每個客戶的醫療信息存儲在數據庫2.

下面是我的代碼：

我在web.config中的ConnectionStrings：

<add name="CNRConnectionString" connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=CNR;Persist Security Info=True;User ID=sa;Password=@#@@@!" providerName="System.Data.SqlClient"/> 

<add name="CNRpeConnectionString" connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=pe;Persist Security Info=True;User ID=sa;Password=@#@@@!" providerName="System.Data.SqlClient"/> 

我的新類（不僅僅是數據，無表連接如）：

namespace DomainModel.Entities 
{ 
    public class ImprimePeriodoPaciente 
    { 
     public int CodConsulta { get; set; } 
     public DateTime DataConsulta { get; set; } 
     public string Evolucao { get; set; } 
     public int CodProfissional1 { get; set; } 
     public int CodPaciente1 { get; set; } 
     public string NomeProfissional { get; set; } //receives data from other db 
     public string NomePaciente { get; set; } //receives data from other db 
     public int CodProcedimento { get; set; } 
     public bool TagConsulta { get; set; } 
     public int? TagConsulta2 { get; set; } 
     public DateTime di { get; set; } 
     public DateTime df { get; set; } 
    } 
} 

這是我的混凝土和接口從的DomainModel：

public class SqlConsultasRepository:IConsultasRepository 
    { 
    private Table<Consulta> consultasTabela; 
    private Table<TEvolucao> tEvolucaoTabela; 
    private Table<Paciente> pacientesTabela; 
    private Table<Funcionario> funcionariosTabela; 

    public SqlConsultasRepository(string connectionString) 
    { 
     consultasTabela = (new DataContext(connectionString)).GetTable<Consulta>(); 
     tEvolucaoTabela = (new DataContext(connectionString)).GetTable<TEvolucao>(); 
     pacientesTabela = (new DataContext(connectionString)).GetTable<Paciente>(); 
     funcionariosTabela = (new DataContext(connectionString)).GetTable<Funcionario>(); 
    } 


     public IQueryable<ImprimePeriodoPaciente> Prontuarios   { 
      get 
      { 
       return 
        (
         from c in consultasTabela 
         join p in pacientesTabela on c.CodPaciente1 equals p.CodigoPaciente //my doom 
         join f in funcionariosTabela on c.CodProfissional1 equals f.CodigoFuncionario //my doom 
         select new ImprimePeriodoPaciente 
         { 
          CodConsulta=c.CodConsulta, 
          DataConsulta=c.DataConsulta, 
          Evolucao=c.Evolucao, 
          NomeProfissional= f.NomeFuncionario, //my doom 
          NomePaciente=p.NomePaciente, //my doom 
          CodProfissional1=c.CodProfissional1, 
          CodPaciente1 = c.CodPaciente1 
         } 
        ); 
      } 

     } 

代碼用'my doom'標記以顯示出現問題的位置....我需要創建對其他數據庫的connectionString引用，因爲這些表不在由connectionString變量指定的當前數據庫中。我收到錯誤，說數據不是來自同一個datacontext（或類似的東西）。

那麼，你能幫忙嗎？

得到了我的方式，通過它基於這個帖子：

對於那些誰在同樣的問題搞定，按照上述步驟後。

林項目中，我自己製作的，從每個數據庫需要分離數據，並把他們分開列出了具體的方法的接口，如下所示：

namespace DomainModel.Concrete 
{ 
    public class SqlImprimePeriodoPacientesRepository : IImprimePeriodoPacientesRepository 
    { 
    private static string cConexao = "Data Source=.\\SQLEXPRESS;Initial Catalog=CNR;Persist Security Info=True;User ID=sa;Password=23092000"; 
    private static string cConexao2 = "Data Source=.\\SQLEXPRESS;Initial Catalog=PE;Persist Security Info=True;User ID=sa;Password=23092000"; 

    private IConsultasRepository cRepository = new SqlConsultasRepository(cConexao2); 
    private IPacientesRepository pRepisotory = new SqlPacientesRepository(cConexao); 
    private IFuncionariosRepository fRepository = new SqlFuncionariosRepository(cConexao); 

    public IQueryable<ImprimePeriodoPaciente> ImprimePeriodoProntuarios//(int? codpac, DateTime? di, DateTime? df) 
    { 
     get 
     { 
      var consultas = 
       (
        from c in cRepository.Consultas 
        select new 
        { 
         c.cdf, 
         c.cdi, 
         c.CodConsulta, 
         c.CodPaciente1, 
         c.CodProcedimento, 
         c.CodProfissional1, 
         c.DataConsulta, 
         c.df, 
         c.di, 
         c.Evolucao, 
         c.TagConsulta, 
         c.TagConsulta2 
        } 
       ) 
       .ToList(); 

      var pacientes = 
       (
        from p in pRepisotory.Pacientes 
        select new 
        { 
         p.CodigoPaciente, 
         p.NomePaciente 
        } 
       ) 
       .ToList(); 

      var funcionarios = 
       (
        from f in fRepository.Funcionarios 
        select new 
        { 
         f.CodigoFuncionario, 
         f.NomeFuncionario 
        } 
       ) 
       .ToList(); 

      var result = 
       (
        from c in consultas 
        join p in pacientes on c.CodPaciente1 equals p.CodigoPaciente 
        join f in funcionarios on c.CodProfissional1 equals f.CodigoFuncionario 
        select new ImprimePeriodoPaciente 
        { 
         CodConsulta = c.CodConsulta, 
         DataConsulta = c.DataConsulta, 
         Evolucao = c.Evolucao, 
         NomeProfissional = f.NomeFuncionario, 
         NomePaciente = p.NomePaciente, 
         CodProfissional1 = c.CodProfissional1, 
         CodPaciente1 = c.CodPaciente1 
        } 
       ).ToList(); 


      return result.AsQueryable(); 
     } 
    } 
} 
} 

這種方法做的工作在Domain'模型方面，所以剩下的就是處理結果。

希望這可以幫助別人！
