Not long ago I blogged about auditing with NHibernate.Envers. I’m using it again in another project but I don’t want to audit all the fields on the entity; furthermore, Envers automatically tries to audit referenced tables, so tables that are not configured to be audited cause an error message: An audited relation from SomeAuditedEntity to a not audited entity NonAuditedEntity! Such mapping is possible, but has to be explicitly defined using [Audited(TargetAuditMode = RelationTargetAuditMode.NotAudited)]. Understandably I expected that adding this attribute to the properties that I didn’t want auditing would prevent this behaviour, but it didn’t. I then added it to the class that I didn’t want auditing, but the message still didn’t go away. A quick google revealed another similar attribute, NotAudited, but this didn’t work either.

Finally after hacking around with my code I stumbled across the solution; the properties to be excluded must be defined in the Envers configuration. Although I think I’d prefer to annotate the fields in the entity class itself, this is the solution that worked for me:

var enversConf = new NHibernate.Envers.Configuration.Fluent.FluentConfiguration();
enversConf.SetRevisionEntity<REVINFO>(e => e.Id, e => e.RevisionDate, new AuditUsernameRevInfoListener());
enversConf.Audit<SomeAuditedEntity>()
          .Exclude(x => x.NonAuditedProperty1)
          .Exclude(x => x.NonAuditedProperty2)
          .ExcludeRelationData(x => x.NonAuditedCollection;
configuration.IntegrateWithEnvers(enversConf);

    If you want to use attribute configuration (like Hibernate Envers), use AttributeConfiguration instead of FluentConfiguration.
