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

You can override the auto-mapped properties as part of your AutoMap in Fluenttly.Configure().

So you can do this:

.Override(map => map.References(x => x.Group).Not.Nullable())

It's not exactly convenient if you have a lot of classes that need this though.

Edit: You can also specify the override in a class that implements IAutoMappingOverride like so:

    public class JobMappingOverride : IAutoMappingOverride
    {
            public void Override(AutoMapping mapping)
            {
                    mapping.References(x => x.Group).Not.Nullable();
            }
    }

and include it like so:

    .UseOverridesFromAssemblyOf()

This would keep your fluent configuration a little cleaner.
