Mixing mapping types

[Steve Mason]

Hi,

I'd like to mix a fluent mapping file with the default AutoMapping
functionality, but I'm coming across the following error:

System.ArgumentException: Object of type
'MyProject.Data.NHibernateMaps.FosterFormMapping' cannot be converted
to type 'FluentNHibernate.AutoMap.AutoMap`1
[MyProject.Core.Domain.FosterForm]'.

\NHibernateSession.cs: line 48

All I've done is define a class in my mapping assembly that implements
ClassMap<FosterForm> (which S#arp has nicely picked up for me). If I
remove this class mapping then the AutoMapping kicks in and everything
works, but I want a different format for the Root entity (FosterForm)
and it's quite complex, so I don't want to use
ForTypesThatDeriveFrom<>.

I'm aware this might be a Fluent NHibernate issue, if so let me know
and I'll re-post over there. I'm running the Trunk version of S#arp,
I haven't tried mapping the additional class using hbm's (yet).

Hi Steve,

Does the following assist: check out the "Mixed fluent mappings and
auto mappings" section at http://blog.jagregory.com/2009/02/03/fluent-nhibernate-configuring-your-application/

Yes, I've seen that and managed to work around the issue. Though I think that the main problem now is that it just doesn't work "Out of the box" where it appears to be engineered in such a way that you can just drop in your ClassMaps to the Data project and automagically have them picked up and made to override the AutoMap stuff?

Here is my workaround for anyone interested, it uses Fluently.Configure from the article Billy mentioned:

            var cfg = new Configuration().Configure();
            var sessionFactory = Fluently.Configure(cfg)
                .Database(...) // Optional
                .Mappings(m =>
                            {
                                m.HbmMappings.AddFromAssemblyOf<FosterFormMapping>();
                                m.FluentMappings.AddFromAssemblyOf<FosterFormMapping>();
                                m.AutoMappings.Add(new AutoPersistenceModelGenerator().Generate());
                            }).BuildSessionFactory();

            NHibernateSession.Storage = new SimpleSessionStorage();
            NHibernateSession.SessionFactory = sessionFactory;

Thanks,
Steve

Thank you Steve! I will add your direction to the documentation.

Hi Billy,

Attached is a patch that changes the base NHibernateSession.Init method to use the Fluently.Configure method directly, as this appears to be the recommended way of configuring Fluent now. This has the effect of fixing my previous issue as well.

I'm using it now and it works, though I must admit that I haven't tried a "traditional" automapped application with it yet.

Great patch Steve...thank you for submitting it! This will be
included in the next check in that I do and in the RC 2 release. I
hope to have that wrapped up by Monday evening.

Hi Guys / Steve

Does anyone have a set of unit tests for NHibernateSession?

Thx
Berryl

[Billy]

Hi Berryl,

Specific unit tests do not exist for this class within
SharpArch.Tests. This class does undergo manual testing and has a
number of indirect unit tests via the tests within the Northwind
sample code. You're most welcome to provide a patch to include some
that directly unit tests this class if you have implementation ideas
for them.

Thanks!
