Hello,
Im having problems using the many to many features in NHBibernate. My
problem is that I cant add an item to an already created object. The only
way for it to work I have to create everything new in the same ISession. Am
I doing it wrong or is this how it works?
my application is developed under Asp.NET MVC 4 with autofac. I'm using the
repository and unit of work pattern.
My objects are the following:
*
[DataContract(IsReference = true)]
[KnownType(typeof(Provincia))]
[KnownType(typeof(CodigoPostal))]
public partial class Localidad
{
[DataMember]
public virtual int Id { get; set; }
[DataMember]
public virtual string Nombre { get; set; }
[DataMember]
public virtual Provincia Provincia { get; set; }
[DataMember]
public virtual IList<CodigoPostal> CodigoPostal { get; set; }
}
[DataContract(IsReference = true)]
[KnownType(typeof(Localidad))]
public partial class CodigoPostal
{
[DataMember]
public virtual int Id { get; set; }
[DataMember]
public virtual string Codigo { get; set; }
[DataMember]
public virtual IList<Localidad> Localidad { get; set; }
}
My mappings:
public partial class CodigoPostalMap : ClassMap<CodigoPostal>
{
public CodigoPostalMap()
{
Id(x => x.Id).GeneratedBy.Identity();
Map(x => x.Codigo).Length(5).Not.Nullable();
HasManyToMany(x =>
x.Localidad).Inverse().LazyLoad().Cascade.SaveUpdate();
}
}
public partial class LocalidadMap : ClassMap<Localidad>
{
public LocalidadMap()
{
Id(x => x.Id).GeneratedBy.Identity();
Map(x => x.Nombre).Length(100).Not.Nullable();
References(x => x.Provincia).Not.Nullable();
HasManyToMany(x =>
x.CodigoPostal).LazyLoad().Cascade.SaveUpdate();
}
}
*
