Hi,
I've just started a project which uses NHibernate, and we also have a
need to provide auditing of our entities - I came acrosss Envers,
which seems to be a perfect solution to our auditing requirement.
I'm trying to map the following Enum with Fluent NHibernate:
public enum AssessmentMethod
{
NotSet,
VanTulder,
ReviewPaper,
UserDefined,
}
public ResearchProjectMap()
{
Id(x => x.Id)
.Column("ResearchProjectId")
.GeneratedBy.Identity();
HasMany(x => x.Studies).Cascade.All();
Map(x => x.Title).Not.Nullable();
Map(x => x.Method).Not.Nullable(); //Assessment Method
Map(x => x.Created).Not.Nullable();
Map(x => x.CreatedBy).Not.Nullable();
}
I'm allowing NHibernate to work out the type for AssessmentMethod,
which works fine for NHibernate to create the domain tables, however
Envers seems to be unable to determine the type for the creation of
the audit tables with the following error:
Could not determine type for: enumstring - AssessmentMethod,
NHibernate.Envers, for columns: NHibernate.Mapping.Column(Method)
I have managed to get it working by using:
Map(x => x.Method).Not.Nullable().CustomType<AssessmentMethod>();
However, this stores the enum value as an int in the database, where I
really want it to be a string, so that Audit data is easier to read.
I must stress that I am pretty new to NHibernate, so I may have made
an obvious mistake in the question being asked.
Thank you in advance,
Pete
