Ninject problem binding to constant value in MVC3 with a RavenDB session
- by Jim
I've seen a lot of different ways of configuring Ninject with ASP.NET MVC, but the implementation seems to change slightly with each release of the MVC framework. I'm trying to inject a RavenDB session into my repository. Here is what I have that's almost working.
public class MvcApplication : NinjectHttpApplication
{
...
protected override void OnApplicationStarted()
{
base.OnApplicationStarted();
AreaRegistration.RegisterAllAreas();
RegisterGlobalFilters(GlobalFilters.Filters);
RegisterRoutes(RouteTable.Routes);
}
protected override IKernel CreateKernel()
{
return new StandardKernel(new MyNinjectModule());
}
public static IDocumentSession CurrentSession
{
get { return (IDocumentSession)HttpContext.Current.Items[RavenSessionKey]; }
}
...
}
public class MyNinjectModule : NinjectModule
{
public override void Load()
{
Bind<IUserRepository>().To<UserRepository>();
Bind<IDocumentSession>().ToConstant(MvcApplication.CurrentSession);
}
}
When it tries to resolve IDocumentSession, I get the following error.
Error activating IDocumentSession using binding from IDocumentSession to constant value
Provider returned null.
Activation path:
3) Injection of dependency IDocumentSession into parameter documentSession of constructor of type UserRepository
Any ideas on how to make the IDocumentSession resolve?
