I am trying to create a ManyToOne map over a legacy database, as such need it to ignore any orphaned records.

The original xml way of describing it was:

<many-to-one not-found="ignore" />

But I am unable to describe it using NHibernate 3.2 Mapping by Code.

The code I am using to describe the map is below:

ManyToOne(x => x.Gang, manyToOne =>
        {
            manyToOne.Column("gang_code");
            manyToOne.Cascade(Cascade.None);
            manyToOne.NotNullable(true);
        });

The NotNullable(true) is there since there should always be a gang for a new or updated record, but need the record to be read/selected to allow users to change it.

Thanks in advance for any help you can provide, it's driving me nuts.

It's not yet supported. You can enter an issue at https://nhibernate.jira.com.

In the meantime, keep using XML to map that class.

You can also clone https://github.com/nhibernate/nhibernate-core and patch (I)ManyToOneMapper

Edit: I implemented it in my fork. I'm too lazy to create the test, Jira and pull request now, but you can use it as-is.

Edit: this is now implemented in the trunk; it will be available in the next release.
