NHibernate.NHibernateException: Unable to locate row for retrieval of generated properties: [MyNames
- by Brad Heller
It looks like all of my mappings are compiling correctly, I'm able to validly get a session from session factory. However, when I try to ISession.SaveOrUpdate(obj); I get this. Can anyone please help point me in the right direction?
private Configuration configuration;
protected Configuration Configuration {
get
{
configuration = configuration ?? GetNewConfiguration();
return configuration;
}
}
protected ISession GetNewSession() {
var sessionFactory = Configuration.BuildSessionFactory();
var session = sessionFactory.OpenSession();
return session;
}
[TestMethod] public void
TestSessionSave() {
var company = new Company();
company.Name = "Test Company 1";
DateTime savedAt = DateTime.Now;
using (var session = GetNewSession())
{
try
{
session.SaveOrUpdate(company);
}
catch (Exception e)
{
throw e;
}
}
Assert.IsTrue((company.CreationDate != null && company.CreationDate > savedAt), "Company was saved, creation date was set."); }
For those that might be interested, here is my mapping for this class:
<!-- Company -->
<class name="MyNamespace.Company,MyLibrary" table="Companies">
<id name="Id" column="Id">
<generator class="native" />
</id>
<property name="ExternalId" column="GUID" generated="insert" />
<property name="Name" column="Name" type="string" />
<property name="CreationDate" column="CreationDate" generated="insert" />
<property name="UpdatedDate" column="UpdatedDate" generated="always" />
</class>
<!-- End Company -->
Finally, here is my config -- I'm just connecting to a SQL Server CE instance for this for testing purposes.
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
<session-factory name="">
<property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
<property name="connection.driver_class">NHibernate.Driver.SqlServerCeDriver</property>
<property name="connection.connection_string">Data Source="D:\Build\MyProject\Source\MyProject.UnitTests\MyProject.TestDatabase.sdf"</property>
<property name="dialect">NHibernate.Dialect.MsSqlCeDialect</property>
<property name="proxyfactory.factory_class">NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle</property>
</session-factory>
</hibernate-configuration>
Thanks!
