EF 6代码的第一列未创建

Question

I am using EF 6 Code First, I don't understand why one column is not created for a property of my Model.

Here is the first class :

    public class Original
    {
    public int ID { get; set; }
    public string Nom { get; private set; }
    public Historique Historique { get; private set; }
    public Traduction Traduction { get; private set; }
    }

And here is the second class :

   public class Traduction
   { 
    public int ID { get; set; }
    public Utilisateur Traducteur { get; private set; }
    public Original Original { get; private set; }
    public string Content { get; private set; }
   }

EF doesn't create the FK column for Traduction and Original. (The Traduction table doesn't contains a FK column for Original and vice versa) but it perfectly creates all the other column and FKs.

I am playing with Fluent API to set up the relationships. I have tried both to rely on the automatic conventions, and to explicitly configure the relation with :

   modelBuilder.Entity<Original>().HasRequired(o => o.Traduction).WithRequiredPrincipal(t=>t.Original).WillCascadeOnDelete(true);

But the columns are still not created.

Thank you for your help

Update

I don't know if it is useful but I would like to add one information, my Dbset are defined like this in the context class :

public DbSet<Traduction> Traductions { get; set; }
public DbSet<Original> Originaux { get; set; }

"Originaux" if the French plural for "Originals". However I have noticed that the Table created by EF is Named "Originals", and doesn't follow the name of the DbSet. I don't know, perhaps it might be a cause of the problem.

Answer 1

As Dismissile said, EF doesn't create an extra column to hold the foreign keys because it is a one-to-one relationship. This is a normal behaviour and nothing is actually wrong.
