Question

I have some questions with relationship of ef code first.
My code:

public class user
{
    public user()
    {
    }

    public int id { get; set; }
    public string code { get; set; }
    public string name { get; set; }
}

public class dep
{
    public int id { get; set; }
    public Nullable<int> UserId { get; set; }
    public virtual user User { get; set; }
}

modelBuilder.Entity<dep>()
            .HasOptional(t => t.User)
            .WithOptionalDependent();

The table dep that code first auto generated has a foreign key named User_Id,
but that is not what I want.
I want to use the column UserId that I defined in the model.
How will I change my code.

Answer 1

Think you can just add an attribute

[ForeignKey("UserId")]

on your User property.

Now, the question is why ? You’re not in a Database, but in a ORM, an object world. You should work with User Navigation property, not with UserId. And if you need UserId, you should use User.Id.

But… that’s your soultion 😉
