good/simple asp.net mvc application with fluent nhibernate..

Question

Where can i find a good/simple asp.net mvc application with fluent nhibernate? Any suggestion..

Answer 1

The orchard cms project uses fluent nhibernate.

Answer 2

I wrote a sample ASP.NET MVC application which uses FluentNHibernate among other open source frameworks. The source code is available on github.

As requested in the comments section I've tried to summarize the important parts of setting FluentNhibernate with ASP.NET MVC:

Start by defining your model:

public class User
{
    public virtual int Id { get; set; }
    public virtual string FirstName { get; set; }
    public virtual string LastName { get; set; }
    public virtual int? Age { get; set; }
}

Then the repository that will allow you to access the model:

using System.Collections.Generic;

public interface IUsersRepository
{
    IEnumerable<User> GetUsers();
    User Get(int id);
    void Delete(int id);
    int Save(User user);
    void Update(User user);
}

Then implement this repository:

using System.Collections.Generic;
using Spring.Data.NHibernate.Generic.Support;

public class SqlUsersRepository : HibernateDaoSupport, IUsersRepository
{
    public IEnumerable<User> GetUsers()
    {
        return HibernateTemplate.LoadAll<User>();
    }

    public User Get(int id)
    {
        return HibernateTemplate.Get<User>(id);
    }

    public void Delete(int id)
    {
        HibernateTemplate.Delete(new User { Id = id });
    }

    public int Save(User user)
    {
        return (int)HibernateTemplate.Save(user);
    }

    public void Update(User user)
    {
        HibernateTemplate.Update(user);
    }
}

So far no FluentNHibernate specific parts. Let's define the mapping now:

using FluentNHibernate.Mapping;

public class UserMap : ClassMap<User>
{
    public UserMap()
    {
        Table("users");
        Id(x => x.Id, "usr_id");
        Map(x => x.FirstName, "usr_firstname");
        Map(x => x.LastName, "usr_lastname");
        Map(x => x.Age, "usr_age");
    }
}

And a Spring.NET session factory which uses SQLite but you could adapt as necessary:

using FluentNHibernate.Cfg;
using FluentNHibernate.Cfg.Db;
using NHibernate;
using NHibernate.ByteCode.Castle;
using NHibernate.Cfg;
using Spring.Data.NHibernate;

public class FluentSessionFactory : LocalSessionFactoryObject
{
    private readonly string _dataFile;
    public FluentSessionFactory(string dataFile)
    {
        _dataFile = dataFile;
    }

    protected override ISessionFactory NewSessionFactory(Configuration config)
    {
        return Fluently
            .Configure()
            .Database(
                SQLiteConfiguration
                    .Standard
                    .UsingFile(_dataFile)
                    .ProxyFactoryFactory<ProxyFactoryFactory>()
            ).Mappings(
                m => m.FluentMappings.AddFromAssemblyOf<UserMap>()
            ).BuildSessionFactory();
    }
}

Next we define a controller:

public class HomeController : Controller
{
    private readonly IUsersRepository _repository;
    public HomeController(IUsersRepository repository)
    {
        _repository = repository;
    }

    public ActionResult Index()
    {
        return View(_repository.GetUsers());
    }
}

Once we have all this in place we need to plumb the pieces together. As we are using Spring.NET we need to provide a custom controller factory:

public class SpringControllerFactory : DefaultControllerFactory
{
    private static readonly IApplicationContext _springContext = ContextRegistry.GetContext();

    protected override IController GetControllerInstance(System.Web.Routing.RequestContext requestContext, Type controllerType)
    {
        if (controllerType != null)
        {
            var objectsOfType = _springContext.GetObjectsOfType(controllerType);
            if (objectsOfType.Count > 0)
            {
                return (IController)objectsOfType.Cast<DictionaryEntry>().First<DictionaryEntry>().Value;
            }
        }
        return base.GetControllerInstance(requestContext, controllerType);
    }
}

Next comes web.config:

<configuration>
  <configSections>
    <sectionGroup name="spring">
      <section name="context" type="Spring.Context.Support.ContextHandler, Spring.Core"/>
    </sectionGroup>
  </configSections>

  <spring>
    <context>
      <resource uri="~/Config/springContext.xml"/>
    </context>
  </spring>


  <system.web>
    <compilation debug="true">
      <assemblies>
        <add assembly="System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
        <add assembly="System.Web.Abstractions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
        <add assembly="System.Web.Routing, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
        <add assembly="System.Web.Mvc, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
      </assemblies>
    </compilation>

    <pages>
      <namespaces>
        <add namespace="System.Web.Mvc" />
        <add namespace="System.Web.Mvc.Ajax" />
        <add namespace="System.Web.Mvc.Html" />
        <add namespace="System.Web.Routing" />
      </namespaces>
    </pages>
  </system.web>

  <system.webServer>
    <validation validateIntegratedModeConfiguration="false"/>
    <modules runAllManagedModulesForAllRequests="true"/>
  </system.webServer>

</configuration>

And finally the springContext.xml:

<?xml version="1.0" encoding="utf-8" ?>
<objects xmlns="http://www.springframework.net"&gt;

  <object
    id="siteRoot"
    type="System.Web.Hosting.HostingEnvironment, System.Web"
    factory-method="get_ApplicationPhysicalPath" />

  <object
    id="dataFile"
    type="System.IO.Path, mscorlib"
    factory-method="Combine">
    <constructor-arg name="path1" ref="siteRoot" />
    <constructor-arg name="path2" value="App_Data\data.db3" />
  </object>

  <object id="sessionFactory" type="AppName.Business.Repositories.FluentSessionFactory, AppName">
    <constructor-arg name="dataFile" ref="dataFile" />
  </object>

  <object id="sqlUsersRepository"
        type="AppName.Business.Repositories.SqlUsersRepository, AppName"
        singleton="false">
    <property name="SessionFactory" ref="sessionFactory"/>
  </object>

  <object id="home"
          type="AppName.Controllers.HomeController, AppName"
          singleton="false">
    <constructor-arg name="repository" ref="sqlUsersRepository" />
  </object>

</objects>
