Creating ASP.NET MVC 4 Project with RavenDB

In this section we will go over the steps to creating you own ASP.NET MVC4 Application.

Prerequisites

1. Make sure you have the Microsoft ASP.NET MVC 4 installed.
2. You have installed NuGet package manager
3. You are running Visual Studio 2010 or greater

Step by Step Instructions

1. Open the Micrsooft Visual Studio IDE. Create a new "ASP.NET MVC 4 Web Application" project.
2. As Project template select "Basic".
3. Add the NuGet Package named "RavenDB Client".
4. Create the following controller:

public abstract class RavenController : Controller
{
public static IDocumentStore DocumentStore
{
	get { return DocumentStoreHolder.Store; }
}

public IDocumentSession RavenSession { get; protected set; }

protected override void OnActionExecuting(ActionExecutingContext filterContext)
{
	RavenSession = DocumentStoreHolder.Store.OpenSession();
}

protected override void OnActionExecuted(ActionExecutedContext filterContext)
{
	if (filterContext.IsChildAction)
		return;

	using (RavenSession)
	{
		if (filterContext.Exception != null)
			return;

		if (RavenSession != null)
			RavenSession.SaveChanges();
	}

	TaskExecutor.StartExecuting();
}

protected HttpStatusCodeResult HttpNotModified()
{
	return new HttpStatusCodeResult(304);
}

protected ActionResult Xml(XDocument xml, string etag)
{
	return new XmlResult(xml, etag);
}

protected new JsonResult Json(object data)
{
	return base.Json(data, JsonRequestBehavior.AllowGet);
}
}

5. From now on, write you application as you would normally, but make any controller that needs to talk to RavenDB inherit from RavenController.

Example of a controller:

public class HomeController : RavenController
{
//
// GET: /Home/

public ActionResult Index()
{
	var items = RavenSession.Query<SampleData>().ToList();
	return View("Index", items);
}

public ActionResult Add(string name)
{
	var sampleData = new SampleData { CreatedAt = SystemTime.UtcNow, Name = name };
	RavenSession.Store(sampleData);
	return RedirectToAction("Edit", new { id = sampleData.Id });
}

public ActionResult Edit(int id)
{
	var sampleData = RavenSession.Load<SampleData>(id);
	return View("Index", new List<SampleData> { sampleData });
}
}
