Hello all,
I've been using Castle ActiveRecord and am interested in starting a new
project using just NHibernate. I'd like to use the latest stable release
which appears to be v3.3.3.4001. I'd like to use the Mapping ByCode
feature since that is similar to the Castle ActiveRecord that I have been
working with and seems to offer me the quickest approach to working. I've
created a simple class
public class Model {
public virtual long ID { get; set; }
}
public class ModelMap : ClassMapping<Model> {
public ModelMap() {
Id(x => x.ID, m => m.Generator(Generators.Identity));
Lazy(false);
}
}
i've created a simple MSTest Unit Test
using SyLogis.Models;
using Microsoft.VisualStudio.TestTools.UnitTesting;
namespace TestProject1
{
[TestClass()]
public class ModelTest {
static InMemoryDatabaseTest imdb = null;
[ClassInitialize()]
public static void MyClassInitialize(TestContext testContext) {
System.Reflection.Assembly assembly =
typeof(NumberedEntityMap).Assembly;
imdb = new InMemoryDatabaseTest(assembly);
}
[TestMethod()]
public void ID_Test() {
Model target = new Model(); // TODO: Initialize to an appropriate
value
long expected = 1; // TODO: Initialize to an appropriate value
long actual;
target.ID = expected;
actual = target.ID;
imdb.session.Save(target);
target = null;
target = imdb.session.Get<Model>(expected);
Assert.AreEqual<long>(expected, target.ID);
}
}
}
and here is the inmemory piece
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using NHibernate;
using NHibernate.Cfg;
using NHibernate.Tool.hbm2ddl;
using System.Reflection;
using System.Data;
namespace TestProject1 {
public class InMemoryDatabaseTest : IDisposable {
public static Configuration Configuration;
public static ISessionFactory SessionFactory;
public ISession session;
public IDbConnection connection;
public InMemoryDatabaseTest(Assembly assemblyContainingMapping) {
try {
if (Configuration == null) {
Configuration = new Configuration()
.SetProperty(NHibernate.Cfg.Environment.ConnectionProvider,
"NHibernate.Connection.DriverConnectionProvider")
.SetProperty(NHibernate.Cfg.Environment.ConnectionDriver,
typeof(SQLite20Driver).AssemblyQualifiedName)
.SetProperty(NHibernate.Cfg.Environment.ConnectionString, "Data
Source=:memory:;Version=3;New=True;")
.SetProperty(NHibernate.Cfg.Environment.ShowSql, "false")
.SetProperty(NHibernate.Cfg.Environment.Dialect,
typeof(SQLiteDialect).AssemblyQualifiedName)
.SetProperty(NHibernate.Cfg.Environment.ReleaseConnections,
"on_close")
.SetProperty(NHibernate.Cfg.Environment.MaxFetchDepth, "1")
.AddAssembly(assemblyContainingMapping);
SessionFactory = Configuration.BuildSessionFactory();
}
session = SessionFactory.OpenSession();
connection = session.Connection;
new SchemaExport(Configuration)
.SetOutputFile(".\\sqlite.sql")
.Execute(true, true, false, connection, Console.Out);
} catch (Exception ex) {
throw;
}
}
public void Dispose() {
session.Dispose();
}
}
}
when i run the test it goes fine until it gets to the Save step at which
point it throws an exception and the test details says there's no
persister. I'm not certain what I'm doing wrong. I don't have any hbm.xml
files to add as Embedded Resources (but I thought that was the point of
Mapping ByCode). I would appreciate any suggestions.
Also all the NHibernate Getting Started samples I can find are for v3.1.0
of NHibernate or even more often v2.1.x or similar. Are there any Getting
Started samples using v3.3.3? If anyone has a working Visual Studio
Solution using NHibernate v3.3.3 and could send it to me or post it
somewhere, that would be much appreciated. Thanks in advance. Have a
great day!
