Hi all,
I'm new on NHibernate and i have a problem with composite element in bags.
I'm working with NHibernate 1.2 RC1, .NET 2.0 and SQL Server 2005
So here's my mapping file
Code:
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" namespace="Dppr.Biologie.Transport" assembly="Dppr.Biologie">
<class name="InfosPatient" table="T_INFOS_PATIENT" lazy="false">
<id name="Identifiant" column="PAT_ID_N" type="Int32" unsaved-value="0">
<generator class="native"/>
</id>
<bag name="Diagnostics" table="T_DIAGNOSTIC" cascade="all" lazy="false">
<key column="PAT_ID_N"/>
<composite-element class="Diagnostic">
<property column="DIA_ID_N" type="Int32" name="Identifiant" insert="false" update="false" />
<property column="DIA_CODE_C" type="String" name="Code" length="20" />
</composite-element>
</bag>
<property column="PAT_IDDEMANDEUR_C" type="String" name="IdPatientDemandeur" length="16" />
</class>
</hibernate-mapping>
and my C# Code for the transport object:
Code:
// Identifiant du patient
private int identifiant = 0;
/// <summary>
/// Identifiant du patient
/// </summary>
/// L'identifiant est un identifiant sequentiel, donc d'aucune utilité pour l'utilisateur
[XmlIgnore]
public virtual int Identifiant
{
get { return this.identifiant; }
set { this.identifiant = value; }
}
// Identifiant du patient attribué par le demandeur
private string idPatientDemandeur;
public virtual string IdPatientDemandeur
{
get { return this.idPatientDemandeur; }
set { this.idPatientDemandeur = value; }
}
// Diagnostic
private System.Collections.Generic.IList<Diagnostic> diagnostics;
[XmlIgnore]
public virtual System.Collections.Generic.IList<Diagnostic> Diagnostics
{
get
{
if (this.diagnostics == null)
{
this.diagnostics = new System.Collections.Generic.List<Diagnostic>();
}
return this.diagnostics;
}
set { this.diagnostics = value; }
}
When I try to insert data in the table "Insert" and "update" attributes of the DIA_ID_N property don't seem to be effective. Indeed NHibernate tries to insert data in the field.
I am looking for a way of preventing data from being inserted in this field. Any idea?
here is the error message I am getting from NHibernate:
Quote:
NHibernate.ADOException: could not insert collection: [Dppr.Biologie.Transport.Analyse.Diagnostics#1] ---> System.Data.SqlClient.SqlException: Cannot insert explicit value for identity column in table 'T_DIAGNOSTIC' when IDENTITY_INSERT is set to OFF..
Thanks in advance for your answers.
Any help will be appreciated.
