[fluent-nhib] Re: Possible Problem with Query Method in IRepository

I'll take a look at your GenericRepository, see if I can replicate the
issue.

 Does that make sense?

[fluent-nhib] Re: Possible Problem with Query Method in IRepository

[James Gregory]

Right, after a lot more experimentation I've come to the conclusion that
it's to do with generic type parameters. I've basically extracted the logic
out of your GenericRepository, reducing it until I can replicate the issue
in the smallest possible form. Take the following test:
Test() _
Public Sub TestLinq()
Dim flRepos As New Repository(_source)

flRepos.Save(New Product())
flRepos.Save(New Product())

flRepos.Query(Function(x As Product) (x.Id = 2))
GetById(Of Product)(2, flRepos)
End Sub

Public Function GetById(Of T As IHasIntId)(ByVal Id As Integer, ByVal
flRepos As IRepository) As T()
Return flRepos.Query(Function(x As T) (x.Id = 2))
End Function

There's a direct Query call on the repository, then there's a call to the
same method inside a helper method that uses a generic type. The direct
Query call succeeds, but the GetById call fails.

If you change the helper method to this:

Public Function GetById(Of T As IHasIntId)(ByVal Id As Integer, ByVal
flRepos As IRepository) As Product()
Return flRepos.Query(Function(x As Product) (x.Id = 2))
End Function

Then it suddenly works. Notice the T is not actually used and it's hard
coded to Product.

My main conclusion is that this is definitely not a Fluent NHibernate issue.
It's something wrong with how Linq to NHibernate handles VBs generic
parameters.

A workaround, and it's not a nice one, is to either have a repository per
type, or create your generic repository in C# (I tried this and it works
without any trouble).

Hi Luis

you need to inform automapper that your base type is EntidadeBase rather
than object, something similar
to below should do the job.

 var autoMapper = AutoPersistenceModel
.MapEntitiesFromAssemblyOfExampleClass()
.Where(t = t.Namespace ==
FluentNHibernate.AutoMap.TestFixtures.SuperTypes)
.WithConvention(c =

c.IsBaseType = b = b ==

});

[fluent-nhib] Re: question on auto mapping

[Andrew Stewart]

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

[fluent-nhib] Re: question on auto mapping

[Luis Abreu]

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.

Ahh, that makes sense now my fault on the understanding. In that case your

If you have time though and we're always willing to except a patch for the

It seems that the auto mapping of inheritance isn't clever enough to map
that model yet, sorry. You'll have to manually map all descendants of Asset

Sorry I hadn't spotted that sneaky one.

[fluent-nhib] Fluent NHibernate and the Windsor NHibernate Integration Facility

[Mike Hadlow]

I'm trying to use Fluent NHibernate with Windsor's NHibernate
Integration
Facility. I was wondering if anyone else has faced this issue.

We've come up with this solution, but I'd like to know if there's
better way:

FNH needs to get access to the NH config. I've used a custom
IConfigurationBuilder (from the NH integration facility) and
registered it with the facitlity:

facility id=nhibernate
  isWeb=false

type=Castle.Facilities.NHibernateIntegration.NHibernateFacility,
Castle.Facilities.NHibernateIntegration

configurationBuilder=WindsorNHibernate.Services.FluentNHibernateConfigurationBuilder,
WindsorNHibernate

My custom configuration builder looks like this:

public class FluentNHibernateConfigurationBuilder :
DefaultConfigurationBuilder
{
public new Configuration GetConfiguration(IConfiguration config)
{
Configuration cfg = new Configuration();

ApplyConfigurationSettings(cfg, config.Children[settings]);
RegisterAssemblies(cfg, config.Children[assemblies]);
RegisterResources(cfg, config.Children[resources]);
RegisterListeners(cfg, config.Children[listeners]);

// Fluent NH call
cfg.AddMappingsFromAssembly(Assembly.GetExecutingAssembly());

return cfg;
}

}

Thanks
Mike

[fluent-nhib] Re: Debugging Xml Output by FNH

[Ryan Kelley]

I believe that using the PersisitnceModel.WritemappingsTo yields
diferent results than the XML that is acutally used if you don't write
the mapings though. By different, I mean the order of the properties
are different. So as long as you are not concerned about what order
the properties come in then it should be fine. The other way is to do
something like this:

 Use an IMappingVisitor to do this:

// This code is the caller to write the files
IListIMapGenerator mappers = GeneratorHelper.GetMapGenerators();
foreach (var mapper in mappers)
{
mapper.Generate().Save(mapper.FileName);

}

Each map I want to write out implements IMapGenerator

public XmlDocument Generate()
{
return CreateMapping(new MappingVisitor());
}

IMapGenerator code:

public interface IMapGenerator
{
string FileName { get; }
XmlDocument Generate();
}

[fluent-nhib] Re: question on auto mapping

[James Gregory]

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
He needs to map it to a timestamp, which is where I get lost as you need to

[fluent-nhib] Re: Debugging Xml Output by FNH

[James Gregory]

I'm still confused by how they can be different orders.
This is how the mappings are added to NHibernate:
public virtual void Configure(Configuration configuration)
{
  _configured = true;

  MappingVisitor visitor = new MappingVisitor(_conventions, configuration,
_chain);
  _mappings.ForEach(mapping = mapping.ApplyMappings(visitor));
}

This is how they're written out:
public void WriteMappingsTo(string folder)
{
  DiagnosticMappingVisitor visitor = new DiagnosticMappingVisitor(folder,
_conventions, null, _chain);
  _mappings.ForEach(m = m.ApplyMappings(visitor));
}

As you can see, they're nigh-on-identical.

[fluent-nhib] PersistentModel - Make Mappings Property

[Chris Bilson]

Does it make sense to want a public property to access the mappings in
a persistent model? I can imagine many uses for this:

 * I want a DiagnosticMappingVisitor that does not need to write to a
folder
 * I want to do some kind of post processing to the mappings
 * I want to build scaffolding (like rails style scaffolding) from the
metadata in the model

This should be very easy to do, I was just wondering if this isn't
exposed on purpose. Thanks!

[fluent-nhib] Re: Fluent NHibernate and the Windsor NHibernate Integration Facility

[Sebastien Lambla]

No luck with the trunk of castle though as it relies on 2.1 and fluent
nhibernate so far seems compiled against 2.0.

Is there a way to change that when compiling fluent nhibernate? Or is there
a 2.0 compat nhibernate facility in castle?

I've had to revert to using a SessionManager and manage my sessions myself.
Not nice!

[fluent-nhib] Re: Debugging Xml Output by FNH

[Ryan Kelley]

The only thing I can think of is maybe this in ClassMapBase:

protected void writeTheParts(XmlElement classElement, IMappingVisitor
visitor)
{
_properties.Sort(new MappingPartComparer());
foreach (IMappingPart part in _properties)
{
part.Write(classElement, visitor);
}
}

where it does the sort on the list before it adds them. Because when I
use CreateMapping vs WriteMappingsTo they are different and
CreateMapping is consistent with what the db/NH sees, unless you do
WriteMappingsTo then that is consistent.

 Hi Luis

 you need to inform automapper that your base type is EntityBase rather
than
 object, something similar
 to below should do the job.

  var autoMapper = AutoPersistenceModel

 .Where(t = t.Namespace ==
 FluentNHibernate.AutoMap.TestFixtures.SuperTypes)
 .WithConvention(c =

 c.IsBaseType = b = b ==

 });

  Hi.

  I'm new to FluentNHibernate / NHibernate, and I would like to ask you
  guys a question about mapping complex (or deep) inheritance
  situations.

  The class hierarchy I have is the following:

  class Asset : EntityBase
  {
   // ...
  }

  class Fund : Asset
  {
   // ...
  }

  class EquityFund : Fund
  {
   // ...
  }

  class FixedIncomeFund : Fund
  {
   //
  }

  class Trade : EntityBase
  {
   public Asset Asset { get; set; }
  }

  I would like to use the AutoMap feature, but NHibernate keep telling
  me that the class Fund is being duplicated in the mappings.

  What am I missing?

I did exactly the same thing, created a custom configuration builder.
I have attached it, plus the patch to get the facilities to build.

Hope this helps,

FYI, there's a Rake target for switching the binaries.  From the trunk/ folder, 
type rake -T.
 
These tasks are of particular interest:
 
rake nhib21   # Builds Fluent NHibernate against the NHibernate 2.1 
lib...
rake use_nhib_20  # Switches NHibernate dependencies to NHibernate 2.0
rake use_nhib_21  # Switches NHibernate dependencies to NHibernate 2.1

The 2.1 NH binaries are in the FNH tree. I've just been copying those
into the parent directory (where the c# projects get their references)
and rebuilding building FNH.

I ended up ditching the castle NH facility, after using it for many
years. I realized what it does is really pretty simple, so I just
built my own Unit of work implementation that handles session
management, per request sessions and transactions in web apps, and of
course integrating with FNH for configuring session factories.

If anyone else is doing this it would be interesting to exchange
ideas.

 No luck with the trunk of castle though as it relies on 2.1 and fluent

 Is there a way to change that when compiling fluent nhibernate? Or is there
 a 2.0 compat nhibernate facility in castle?

 I've had to revert to using a SessionManager and manage my sessions myself.
 Not nice!

 Woops, sorry that code above won't work. You have to create you own
 IConfigurationBuilder. This one is tested and works:

 public class FluentNHibernateConfigurationBuilder :

 {

 public Configuration GetConfiguration(IConfiguration config)
 {
 Configuration cfg = new Configuration();

 ApplyConfigurationSettings(cfg,
 config.Children[settings]);

 cfg.AddMappingsFromAssembly(typeof(Order).Assembly);

 AdditionalConfiguration(config, cfg);

 return cfg;
 }

 /// summary
 /// Override this method to provide additional configuration
 /// /summary

 /// /summary

 protected void ApplyConfigurationSettings(Configuration cfg,
 IConfiguration facilityConfig)
 {
 if (facilityConfig == null) return;

 foreach (IConfiguration item in facilityConfig.Children)
 {
 String key = item.Attributes[key];
 String value = item.Value;

 cfg.SetProperty(key, value);
 }
 }
 }

[fluent-nhib] Re: question on auto mapping

[Luis Abreu]

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

[fluent-nhib] Re: question on auto mapping

[Luis Abreu]

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.

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?

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: PersistentModel - Make Mappings Property

[Paul Batum]

Hi Chris,

I am afraid that in its current state, even if the mappings were publicly
accessible, you would struggle to extract all the necessary data from them.
It is further complicated by the fact that you would want to access the data
AFTER conventions have been applied, but in some cases the conventions only
modify the output xml, not the model itself.

I would encourage you to pull the source down, change it to public and try
working against it - I suspect you will find that this is not quite as
simple as making the mappings public.

  This should be very easy to do, I was just wondering if this isn't
