Fluent NHibernate enforce Not Nullable on Foreign Key Reference

Question

Just getting my feet wet with some Fluent NHibernate AutoMap conventions, and ran into something I couldn\'t figure out. I assume I\'m just not looking in the right place...

Answer 1

It seems that IPropertyConvention is only called on simple properties of your classes. If your property references another class, you need to use IReferenceConvention too.

Try this:

public class FluentConvention : IPropertyConvention, IReferenceConvention  
{      
    public void Apply(IPropertyInstance instance)
    {          
        instance.Not.Nullable();      
    }

    public void Apply(IManyToOneInstance instance)
    {
        instance.Not.Nullable();
    }
}
