Entity Framework, how to work with not mapped entities

Question

I've got a doubt about working with not mapped POCO entities. I have an Entity that contains properties(and this properties are other POCO classes that are mapped to the database).

I've got a generic repository where this repository receives an generic entity to work with:

public class BaseRepository<TEntity> : IBaseRepository<TEntity> where TEntity : class
{
    internal readonly DbContext recuperadorContext;
    internal readonly IDbSet<TEntity> dbSet;

    public BaseRepository(DbContext context)
    {
        recuperadorContext = context;
        dbSet = recuperadorContext.Set<TEntity>();
    }

    public TEntity Adicionar(TEntity obj)
    {
        var objReturn = dbSet.Add(obj);
        return objReturn;
    }

}

The implementation is:

public class CupomFiscalRepository : BaseRepository<CupomFiscalDetalhes> 
{
}

The not mapped entity with it's properties is described bellow:

public class CupomFiscalDetalhes
{
    public Movimento Movimento { get; set; } //POCO class mapped
    public Cliente ClienteCRM { get; set; } //POCO class mapped
    public Vendedor Vendedor { get; set; } //POCO class mapped
}

Since CupomFiscalDetalhes does not have a table to be mapped, do I need to have all the POCO classes mapped in EntityFramework to work with ht? Asking because I don't know how I'm going to save these data to the database with the generic repository.

Answer 1

If you need to persist CupomFiscalDetalhes then you should add it to the context. If you don't need to persist CupomFiscalDetalhes then it shouldn't implement IBaseRepository and you should consider it a view of data populated via a controller class.
