Error with dependency injection and generic base class - dependency-injection

Question

I am learning repository and unit of work patterns using generics and dependency injection. I have a persistent error that I have been churning on and I am clearly missing something fundamental.
I am getting the following error which whilst I understand that it is looking for a database table column called 'Id'
Because my Entity class inherits from BaseEntity I suspect this is the problem but I don't understand why and what I am best to do to fix it.
public class BaseEntity<T>
{
public T Id { get; set; }
}
Error returned
An exception of type 'System.Data.Entity.Core.EntityCommandExecutionException' >occurred in EntityFramework.SqlServer.dll but was not handled in user code
Additional information: An error occurred while executing the command >definition. See the inner exception for details.
Inner exception
{"Invalid column name 'Id'."}
To add some context I am using EF6 MVC5 and AutoFac for the Dependancy injection.
Entity class
(A column 'id' doesn't exist in the database - the key in the database is 'EmrgencyAttendanceId') and the Entity class also sets the key as 'EmrgencyAttendanceId' like so.
[Table("reporting.EDISRecords")]
public class EDISRecord : BaseEntity<int>
{
[Key]
[DatabaseGenerated(DatabaseGeneratedOption.None)]
public int EmergencyAttendanceId { get; set; }
[StringLength(50)]
public string Hospital { get; set; }
[StringLength(20)]
public string URNumber { get; set; }
Controller action
The controller calls the GetRecord method of the EDISRecordService passing a Lambda expression. I use DbFunctions.TruncateTime because the database stores as date time and I only want to search on the date.
public ActionResult Search(string Date, string CaseNumber)
{
if (!string.IsNullOrEmpty(Date) || !string.IsNullOrEmpty(CaseNumber))
{
DateTime dt = DateTime.Parse(Date);
var EmergencyAttendance = _edisRecordService.GetRecord(m => (DbFunctions.TruncateTime(m.ArrivalDateTime) == dt) && (m.RTAIdentifier == CaseNumber));
//for initialising view model
SeperationSummaryViewModel model = new SeperationSummaryViewModel();
//assign values for view model
if (EmergencyAttendance != null)
{
if (EmergencyAttendance.DepartureDestination != null)
{
if (EmergencyAttendance.DepartureDestination.Substring(0, 1) == ".")
{
model.DepartureDestination = EmergencyAttendance.DepartureDestination.Substring(1);
}
else
{
model.DepartureDestination = EmergencyAttendance.DepartureDestination;
}
}
else
{
model.DepartureDestination = "Not recorded by Emergency Department";
}
if (EmergencyAttendance.InpatientAdmissionDiagnosis != null)
{
model.InpatientAdmissionDiagnosis = EmergencyAttendance.InpatientAdmissionDiagnosis;
}
else
{
model.InpatientAdmissionDiagnosis = "Not recorded by Emergency Department";
}
}
//send view model into UI (View)
return PartialView("_SeperationInformationPartialView", model);
}
else
{
if (string.IsNullOrEmpty(Date) || string.IsNullOrEmpty(CaseNumber))
{
return PartialView("Blank");
}
}
return PartialView("Error");
}
Service Class
The service class instantiates a unit of work and calls the repository Get method passing through the Lambda expression.
public class EDISRecordService : IEDISRecordService
{
private readonly IUnitOfWork<DataWarehouseDataManager> _unitOfWork;
public EDISRecordService(IUnitOfWork<DataWarehouseDataManager> unitOfWork)
{
_unitOfWork = unitOfWork;
}
public EDISRecord GetRecord(Expression<Func<EDISRecord, bool>> #where)
{
return _unitOfWork.EDISRecordRepository.Get(#where);
}
}
RepositoryBase class
The repository class inherits from the repository base class which impliments the Get method passing the lambda to 'Expression> #where'
public class RepositoryBase<TEntity> : Disposable, IRepository<TEntity>
where TEntity : class
{
private readonly DbContext _dataContext;
private IDbSet<TEntity> Dbset
{
get { return _dataContext.Set<TEntity>(); }
}
public RepositoryBase(DbContext dbContext)
{
_dataContext = dbContext;
}
public TEntity Get(Expression<Func<TEntity, bool>> #where)
{
return Dbset.Where(where).FirstOrDefault();
}
protected override void DisposeCore()
{
if (_dataContext != null)
_dataContext.Dispose();
}
}
It fails in this method
public TEntity Get(Expression<Func<TEntity, bool>> #where)
{
return Dbset.Where(where).FirstOrDefault(); <<<<<< Fails Here <<<<<
}

Answer 1

I was on the right track and it was because I was inheriting from the Base Entity.
When I re read my problem it became clear.
The solution was to simply not to inherit from base entity class and all is good.
