I've searched everywhere and can't find an example that fits this. I
really could use some help I keep getting the error:
"Could not format discriminator value to SQL string of entity..."
I have a User class with an enum property, UserRole, that I want to be
my discriminator.
public abstract class User
{
public string Name;
public virtual UserRole Role { get; protected set; }
}
I then have a subclass for each role:
public class Teacher : User
{
public Teacher()
{
Role = UserRole.Teacher;
}
}
I don't have any property on Teacher referring to Role because I don't
need it. This is different from what I've seen in other examples.
Here's how I tried to map it on my User mapping:
mapping.DiscriminateSubClassesOnColumn<UserRole>("Role",
UserRole.Teacher)
.SubClass<Teacher>(t =>
{
t.Map(x => x.Role);
}
);
Here's my mapping output:
