Hi, this is my model :
class model2 : DbContext
{
public DbSet<Tab> Tabs { get; set; }
public DbSet<ChildTab> ChildTabs { get; set; }
public model2()
{
Database.SetInitializer(new DropCreateDatabaseIfModelChanges<model2>());
}
public model2(string conn)
: base(conn)
{
Database.SetInitializer(new DropCreateDatabaseIfModelChanges<model2>());
}
}
public class Tab
{
[Key]
public int kcol { get; set; }
public long int64 { get; set; }
public string col { get; set; }
}
public class ChildTab
{
[Key]
public int kcol { get; set; }
public long int64 { get; set; }
public string col { get; set; }
public Tab parenttab { get; set; }
[DatabaseGeneratedAttribute(DatabaseGeneratedOption.None)]
public int Tabkcol { get; set; } //will be FK
}
and here is my code:
model2 ctx = new model2("EF_Oracle_11g_UTF16");
ctx.Tabs.Add(new Tab { });
ctx.ChildTabs.Add(new ChildTab { }); // this will automatically insert above object as parent, if we comment above statement it will throw error
I am expecting a exception here, like "parent key not found"(because the Tabkcol value will be 0 by default), but it doesn't throw.
Is this is something by design or unexpected behavior?
