Hello Luis,
I'm away from a machine with Visual Studio on right now, so I don't know
how much help I can be, but lets try to work through your problem.
Firstly, why is it that you're using a IUserType for your version? What is
the type that your version property has in your entity? I ask that because
Fluent NHibernate has a few options for mapping Versions and Timestamps.
- If you call your property Timestamp and give it a type of TimeSpan,
Fluent NHibernate will automatically map that to a Timestamp.
- If you call your property Version, and give it a type of int or long,
then it will map it as a Version.
Are any of those possible options for you?

Hi james
Thanks for looking at this for me. Yeah that makes sense as to why it's
producing no xml. Luis are your problems solved now? Unfortunalty there is
no automatic way to map your version column at this time, you'll have to
take your manual mapping and apply it in the FromDerivedFromClass for each
class in your solution.
I think that should sort your issue out.

Yeah, it looks like now that is the solution for this problem. Using
entityBase results in the creation of mappings for entitybase (which results
in an exception because I'm only defining the class with a version element
and that triggers an exception).
Regarding the configuration, I was a little bit puzzled because I tried
adding the ForTypesThatDeriveFromEntidadeBase line I've shown in the
previous mail and with that line I was getting the XML for the EntidadeBase
class but not for the Disciplina class and that was something I wasn't
expecting.

Now, I'm just trying to run a simple test to check the mapping of a single

to the where method should be more than enough for testing only the
Disciplina class. My problem is that Disciplina inherits from EntidadeBase
(which defined the Id and Version properties shared by all the entities)
and
the autopersistence model insists in generating an insert into
EntidadeBases
table when I use the Persistence Specification to test the mappings.
Can anyone tell me why this happens and how to solve this? Can't I use
inheritance in my classes and auto mapping? Thanks.

[fluent-nhib] Re: question on auto mapping
No Problem,
The version column as a timestamp you can use the Timestamp function of
nhibernate, to do so set the GetVersionColumnName convention to your
timestamp columnname and it should automagically pick that up to. I dont
think you need a custom user type in this situation.
Good Luck

private static PersistenceModel ObtemAutoConfiguracao()
{
return
AutoPersistenceModel.MapEntitiesFromAssemblyOfDisciplina()
.Where(
type = type == typeof(Disciplina)
) //comecar com disciplina
.WithConvention(convention =
{
convention.DefaultLazyLoad = false;
convention.FindIdentity = field =

String.Concat(type.Name, s);
convention.GetVersionColumnName =
type = Versao;
convention.GetPrimaryKeyNameFromType
= type = String.Concat(Id, type.Name);
});
}
Now, I'm just trying to run a simple test to check the mapping of a single
class (Disciplina). I was under the impression that the lambda I've passed
to the where method should be more than enough for testing only the
Disciplina class. My problem is that Disciplina inherits from EntidadeBase
(which defined the Id and Version properties shared by all the entities)
and
the autopersistence model insists in generating an insert into
EntidadeBases
table when I use the Persistence Specification to test the mappings.
Can anyone tell me why this happens and how to solve this? Can't I use
inheritance in my classes and auto mapping? Thanks.

[fluent-nhib] Re: question on auto mapping
Hello again.
One quick thing, it seems at the moment, the property that timestamps must
be called version or timestamp, otherwise you'll have to manually map it.
I tried using Timestamp but then NH tries to use datetime. That's why I'm
using a custom user type and it seems like it's working (at least the
PersistenceSpecification isn't throwing any errors.
So, what I need is to add this from my manual mapping class:
Version(d = d.Versao)
.TheColumnNameIs(Versao)
.SetAttributes(
new Attributes
{
{type,
ModeloOO.NH.UserTypeTimestamp,ModeloOO.NH},
{unsaved-value, null},
{generated, always}
}
);
So that it is applied to all the types that derive from EntidadeBase class.
I tried this:
var modeloPersistencia =
AutoPersistenceModel.MapEntitiesFromAssemblyOfDisciplina()
.Where(
type = type == typeof (Disciplina)
) //comecar com disciplina
.WithConvention(convention =
{
convention.DefaultLazyLoad = false;
convention.FindIdentity = field =
field.Name == Id;
convention.GetTableName = type =
String.Concat(type.Name, s);
convention.GetVersionColumnName =
type = Versao;
convention.GetPrimaryKeyNameFromType
= type = String.Concat(Id, type.Name);
convention.IsBaseType = type = type
== typeof (EntidadeBase);
});
modeloPersistencia.ForTypesThatDeriveFromEntidadeBase(
eb =
eb.Version(d = d.Versao)
.TheColumnNameIs(Versao)
.SetAttributes(
new Attributes
{
{type,
ModeloOO.NH.UserTypeTimestamp,ModeloOO.NH},
{unsaved-value, null},
{generated, always}
}
));
But by doing this it insists on generating a class definition for
Entidadebase
Thanks.

Hi Luis
Ahh, that makes sense now my fault on the understanding. In that case your
only option is to manually map the Version for each class.
If you have time though and we're always willing to except a patch for the
problem, you would need to ammend the AutoMapVersion class.
Cheers

I mean, should I add classmaap derived classes with only the version definition and then merge them with my auto persistence model? If so, which methods am I supposed to use? Thanks again.

convention.IsBaseType = type = type

});
modeloPersistencia.WriteMappingsTo(@d:\);
Shouldn't I get the xml mapping file for class Disciplina on d:? I've tried
and I get nothing there (interestingly, if I add the
modeloPersistencia.ForTypesThatDeriveFroEntidadeBase method call then I do
get the xml for EntidadeBase only (which I don't want)...

[fluent-nhib] Re: question on auto mapping
Hello Luis,
I'm away from a machine with Visual Studio on right now, so I don't know how
much help I can be, but lets try to work through your problem.
Firstly, why is it that you're using a IUserType for your version? What is
the type that your version property has in your entity? I ask that because
Fluent NHibernate has a few options for mapping Versions and Timestamps.
- If you call your property Timestamp and give it a type of TimeSpan,
Fluent NHibernate will automatically map that to a Timestamp.
- If you call your property Version, and give it a type of int or long,
then it will map it as a Version.
Are any of those possible options for you?

[fluent-nhib] Re: question on auto mapping
Hi James
He needs to map it to a timestamp, which is where I get lost as you need to
use IUserType to make that work which I have no idea how to use.
Thanks for helping, I think you know how that all works better than myself.

[fluent-nhib] Re: question on auto mapping
Hello James. Thanks for the help! Firstly, why is it that you're using a IUserType for your version? What is the type that your version property has in your entity? I ask that because Fluent NHibernate has a few options for mapping Versions and Timestamps. On the class, I have a Byte[] property which is mapped to a timestamp column on an sql server express database. According to the docs, the version element won't be able to match this type. that's why I had to build my own IUserVersionType. Btw, I've followed this article (though I've changed the code a little bit - removing those useless try/catch blocks were really the least I could do!): http://www.codeproject.com/KB/dotnet/OptLocking_PrefixTable.aspx Ok, now with manual mappings, I'm able to make it work (at least, I don't get any exception on my persistency checking. Now, the problem is how do I use the same version column for all the entities where all of them inherit from a base class (EntidadeBase) which is only there for the OO part... Any ideas on how to do this? Luis --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Fluent NHibernate group.

[fluent-nhib] Re: question on auto mapping
Btw James, one more question:
When using the auto persistence, shouldn't I be able to save the xml to
disk by using the previous code? It's that I get nothing and stopping the
debugger there I see 0 mappings on the persistencemodel
Thanks.
