Fluent NHibernate:使用 CheckList 测试集合映射

我在一些项目中使用了 Fluent NH,但在使用 PersistenceSpecification 类测试集合映射时遇到了一些问题。这是我的类的代码(我只是将集合定义放在这里):

public class Ocorrencia : EntityWithAction, IHasAssignedId<Int32> {     
  private IList<Intervencao> _intervencoes = new List<Intervencao>();
  public IEnumerable<Intervencao> Intervencoes {
   get{
   return new ReadOnlyCollection<Intervencao>( _intervencoes );
  }
 set {
   _intervencoes = new List<Intervencao>( value );
   Contract.Assume(_intervencoes != null);
 }
}   
public void ModificaEstado(Intervencao intervencao ){
 //some checks removed
 intervencao.Ocorrencia = this;
 _intervencoes.Add(intervencao);
}
//more code removed

}
public class Intervencao : EntityWithAction, IHasAssignedDomainAction {
//other code remove
internal Ocorrencia Ocorrencia { get; set; }
}

这是映射(仅重要的事情):

public class IntervencaoMapping: ClassMap<Intervencao> {
public IntervencaoMapping()
{            
    WithTable("Intervencoes");
    Not.LazyLoad();
    Id(intervencao => intervencao.Id)
        .ColumnName("IdIntervencoes")
        .WithUnsavedValue(0)
        .SetGeneratorClass("identity");
    Map(intervencao => intervencao.Guid, "Guid")
        .Not.Nullable();
    Version(ent => ent.Version)
       .ColumnName("Version");
    References(ent => ent.Action, "IdAccao")
        .Cascade
        .SaveUpdate();
    Map(intervencao => intervencao.TipoEstado, "TipoEstado")
        .CustomTypeIs(typeof (TipoEstado))
        .CustomSqlTypeIs("integer");
    Map(intervencao => intervencao.Observacoes, "Observacoes");
    References(intervencao => intervencao.Ocorrencia, "IdOcorrencias")
           .Not.LazyLoad();
}
}
public class OcorrenciaMapping: ClassMap<Sra.Ocorrencias.Ocorrencia> {
public OcorrenciaMapping()
{            
    WithTable("Ocorrencias");
    Not.LazyLoad();
    Id(ocorrencia => ocorrencia.Id)
        .ColumnName("IdOcorrencias")
        .WithUnsavedValue(0)
        .SetGeneratorClass("identity");
    Map(ocorrencia => ocorrencia.Guid, "Guid")
        .Not.Nullable();
    Version(ocorrencia => ocorrencia.Version)
        .ColumnName("Version");
    Map(ocorrencia => ocorrencia.Descricao)
        .ColumnName("Descricao");
    Map(ocorrencia => ocorrencia.Nif, "Nif")
        .Not.Nullable();
    Map(ocorrencia => ocorrencia.TipoOcorrencia, "TipoOcorrencia")
         .CustomTypeIs(typeof(TipoOcorrencia))
        .CustomSqlTypeIs("integer");
    Map(ocorrencia => ocorrencia.BalcaoEntrada, "Balcao")
        .CustomTypeIs(typeof(TipoBalcao))
        .CustomSqlTypeIs("integer")
        .Not.Nullable();

    References(ocorrencia => ocorrencia.Organismo, "IdOrganismos")
        .Cascade.None()
        .Not.Nullable();
    HasMany(ocorrencia => ocorrencia.Intervencoes)
            .Access.AsCamelCaseField(Prefix.Underscore)
            .AsBag()
            .Cascade
            .All()
            .KeyColumnNames.Add("IdOcorrencias")
            .Not.LazyLoad();
}
}

如您所见,Interncao 对象是通过 ModificaEstado 方法添加的,该方法确保 Ocorrencia 对 Intervencao 的引用“点”参考奥科伦西亚。现在,如何测试与 PersistenceSpecification 对象的这种关系?我最终得到了以下代码:

[Test]
public void Test() {
using (var session = _factory.GetSession()) {
    using (var tran = session.BeginTransaction()) {

        var accao = CreateAction();
        session.Save(accao);

        var organismo = CreateOrganismo();
        session.Save(organismo);

        var intervencao = CreateIntervencao();
        ((IHasAssignedDomainAction)intervencao).SetActionTo(accao);
        var intervencoes = new List<Intervencao> {intervencao};

        new PersistenceSpecification<Ocorrencia>(session)
            .CheckProperty(e => e.Nif, _nif)
            .CheckProperty( e =>e.Organismo, organismo)
            .CheckProperty( e => e.Descricao, _descricao)
            .CheckProperty( e => e.TipoOcorrencia, TipoOcorrencia.Processo)
            .CheckList( e => e.Intervencoes, intervencoes)
            .VerifyTheMappings());

            tran.Rollback();
    }
}
}

由于 IdOcorrencia 被定义为表 Intervencoes 中的外部键,因此前面的代码会失败,因为它尝试插入 IdOcorrencia 设置为 null 的 intervencoes 列表。如果我删除外部密钥,那么测试工作正常,但我相信我不应该这样做。

我可能做错了什么,但我不确定那是什么。那么,有人可以好心地告诉我如何解决这个问题吗?

谢谢你们。 路易斯

I've used Fluent NH in some projects but I'm having some problems with using the PersistenceSpecification class for testing a collection mapping. Here's the code for my classes (I'm just putting here the collection definition):

public class Ocorrencia : EntityWithAction, IHasAssignedId<Int32> {     
  private IList<Intervencao> _intervencoes = new List<Intervencao>();
  public IEnumerable<Intervencao> Intervencoes {
   get{
   return new ReadOnlyCollection<Intervencao>( _intervencoes );
  }
 set {
   _intervencoes = new List<Intervencao>( value );
   Contract.Assume(_intervencoes != null);
 }
}   
public void ModificaEstado(Intervencao intervencao ){
 //some checks removed
 intervencao.Ocorrencia = this;
 _intervencoes.Add(intervencao);
}
//more code removed

}
public class Intervencao : EntityWithAction, IHasAssignedDomainAction {
//other code remove
internal Ocorrencia Ocorrencia { get; set; }
}

And here's the mappings (only the important things):

public class IntervencaoMapping: ClassMap<Intervencao> {
public IntervencaoMapping()
{            
    WithTable("Intervencoes");
    Not.LazyLoad();
    Id(intervencao => intervencao.Id)
        .ColumnName("IdIntervencoes")
        .WithUnsavedValue(0)
        .SetGeneratorClass("identity");
    Map(intervencao => intervencao.Guid, "Guid")
        .Not.Nullable();
    Version(ent => ent.Version)
       .ColumnName("Version");
    References(ent => ent.Action, "IdAccao")
        .Cascade
        .SaveUpdate();
    Map(intervencao => intervencao.TipoEstado, "TipoEstado")
        .CustomTypeIs(typeof (TipoEstado))
        .CustomSqlTypeIs("integer");
    Map(intervencao => intervencao.Observacoes, "Observacoes");
    References(intervencao => intervencao.Ocorrencia, "IdOcorrencias")
           .Not.LazyLoad();
}
}
public class OcorrenciaMapping: ClassMap<Sra.Ocorrencias.Ocorrencia> {
public OcorrenciaMapping()
{            
    WithTable("Ocorrencias");
    Not.LazyLoad();
    Id(ocorrencia => ocorrencia.Id)
        .ColumnName("IdOcorrencias")
        .WithUnsavedValue(0)
        .SetGeneratorClass("identity");
    Map(ocorrencia => ocorrencia.Guid, "Guid")
        .Not.Nullable();
    Version(ocorrencia => ocorrencia.Version)
        .ColumnName("Version");
    Map(ocorrencia => ocorrencia.Descricao)
        .ColumnName("Descricao");
    Map(ocorrencia => ocorrencia.Nif, "Nif")
        .Not.Nullable();
    Map(ocorrencia => ocorrencia.TipoOcorrencia, "TipoOcorrencia")
         .CustomTypeIs(typeof(TipoOcorrencia))
        .CustomSqlTypeIs("integer");
    Map(ocorrencia => ocorrencia.BalcaoEntrada, "Balcao")
        .CustomTypeIs(typeof(TipoBalcao))
        .CustomSqlTypeIs("integer")
        .Not.Nullable();

    References(ocorrencia => ocorrencia.Organismo, "IdOrganismos")
        .Cascade.None()
        .Not.Nullable();
    HasMany(ocorrencia => ocorrencia.Intervencoes)
            .Access.AsCamelCaseField(Prefix.Underscore)
            .AsBag()
            .Cascade
            .All()
            .KeyColumnNames.Add("IdOcorrencias")
            .Not.LazyLoad();
}
}

As you can see, Interncao objects are added through the ModificaEstado method which ensures that Ocorrencia reference on Intervencao "points" to a reference of Ocorrencia. Now, how do I test this relationship with the PersistenceSpecification object? I've ended up with the following code:

[Test]
public void Test() {
using (var session = _factory.GetSession()) {
    using (var tran = session.BeginTransaction()) {

        var accao = CreateAction();
        session.Save(accao);

        var organismo = CreateOrganismo();
        session.Save(organismo);

        var intervencao = CreateIntervencao();
        ((IHasAssignedDomainAction)intervencao).SetActionTo(accao);
        var intervencoes = new List<Intervencao> {intervencao};

        new PersistenceSpecification<Ocorrencia>(session)
            .CheckProperty(e => e.Nif, _nif)
            .CheckProperty( e =>e.Organismo, organismo)
            .CheckProperty( e => e.Descricao, _descricao)
            .CheckProperty( e => e.TipoOcorrencia, TipoOcorrencia.Processo)
            .CheckList( e => e.Intervencoes, intervencoes)
            .VerifyTheMappings());

            tran.Rollback();
    }
}
}

Since IdOcorrencia is defined as an external key in table Intervencoes, the previous code fails because it tries to insert the intervencoes list with IdOcorrencia set to null. If I remove the external key, then the test works fine, but I believe that I shouldn't be doing that.

I'm probably doing something wrong but I'm not sure on what that is. So, can anyone be kind enough and give me a hint on how to solve this?

thanks guys.
Luis

问题是我使用的是旧版本的 Fluent nhibernate。最近的版本具有可让您解决此类问题的覆盖:

The problem was that I was using an old version of the fluent nhibernate. recente versions have overrides which let you solve this kind of problem:
