Entity Framework Code first, relation between models
Is there someone who will listen to me and help me solve my problem?
I have 3 classes (Product, Lot and Rem):
Each Product has many Lot and each Lot has many Rem.
public class Product {
public int id { get; set; }
public string name { get; set; }
}
public class Lot {
public int id { get; set; }
public decimal price { get; set; }
}
public class Rem {
public int id { get; set; }
public string note { get; set; }
}

What about aList<Lot>as a class member ofProductas well as aList<Rem>as a class member ofLot? You would have to implement someadd(Lot lot)andremove(Lot lot)if you are in need of those actions. Same forLotand itsRems...

From what you described above this is a simple way for related entities in EF.
public class Product {
public int id { get; set; }
public string name { get; set; }
public Lot LotId {get; set; }
public ICollection<Lot> Lots { get; set; }
}
public class Lot {
public int id { get; set; }
public decimal price { get; set; }
public Product ProductId {get; set; }
public Product Product {get; set; }
public Rem RemId {get; set; }
public ICollection<Rem> Rems { get; set; }
}
public class Rem {
public int id { get; set; }
public string note { get; set; }
public Lot LotId {get; set; }
public Lot Lot { get; set; }
}
And the dbcontext class
public class AppDbContext: DbContext
{
public AppDbContext(DbContextOptions<AppDbContext> options): base(options)
{
}
public DbSet<Product> Products { get; set; }
public DbSet<Lot> Lots { get; set; }
public DbSet<Rem> Rems { get; set; }
}
