nancy.bootstrappers.ninject's Issues

Ninject binding issue with IDiagnosticsProvider

Hi,

it all worked when I used the Nancy internal IoC. With this lib I now get this exception:

A first chance exception of type 'Ninject.ActivationException' occurred in Ninject.dll
Additional information: Error activating IntPtr
No matching bindings are available, and the type is not self-bindable.
Activation path:
4) Injection of dependency IntPtr into parameter method of constructor of type Func{IRouteCache}
3) Injection of dependency Func{IRouteCache} into parameter routeCacheFactory of constructor of type DefaultRouteCacheProvider
2) Injection of dependency IDiagnosticsProvider into parameter diagnosticProviders of constructor of type DefaultDiagnostics

Request for IDiagnostics

I am using the latest stable nuget packages:

Nancy 0.23.2
Nancy.Bootstrappers.Ninject 0.23.2
Ninject 3.0.1.10
Ninject.Extensions.ChildKernel 3.0.0.5

I have a workaround. Injecting this bind in the bootstrapper:

protected override void ConfigureApplicationContainer(IKernel existingContainer)
{
  base.ConfigureApplicationContainer(existingContainer);
  existingContainer.Rebind<Func<IRouteCache>>().ToMethod(ctx =>
     () => ctx.Kernel.Get<IRouteCache>());
   // A Bind might be enough.
}

The problem might be that Ninject cannot inject into constructor parameters of type Func<Interface> as is the case in DefaultRouteCacheProvider.

Am I doing anything wrong or am I just the first to notice this?

Support of Ninject3

I can see that support for Ninject3 has been provided with-in this commit.

I've installed Nancy.Bootstrappers.Ninject via Nuget and application started to throw an exception, related missing Bind method. It really smells like NuGet version still depended on Ninject 2.

PS. Latest NuGet package is dated Monday, May 07, 2012 - but Ninject 3 support provided in June, so looks like NuGet package is not up-to-date. As workaround I'll try to build it from sources.

Ninject v3.2.2 dependency resolution issue

The latest release of Ninject (v3.2.2) does not work out of the box with Bootstrappers.Ninject - the dependency resolution is picking up the wrong version of Ninject's Child Kernel library - see below for package manager output:

PM>

Manually installing Ninject.Extensions.ChildKernel v3.2.0.0 first, and then installing the bootstrapper works. I assume this is because You're trying to target multiple versions of Ninject with a single package but I think Ninject's versioning may prohibit this. The only way I could therefore see this working would be to mirror the Ninject version's the same was as the ChildKernel library is doing, or eliminate support for older versions...

Either way, I thought I would raise it.

Thanks.

Ninject Bootstrapper not working with UseNancy() Owin AppBuilderExtensions

I am trying to use Nancy in a console hosted Owin app.
My Bootstrapper and the main startup of Nancy are defined as follows:

//NOTE: kernel is a static variable and is the ninject StandardKernel

    public class Bootstrapper : NinjectNancyBootstrapper
    {
        protected override IKernel GetApplicationContainer()
        {
            kernel.Load<FactoryModule>();
            return kernel;
        }

        protected override void ConfigureConventions(NancyConventions nancyConventions)
        {
            base.ConfigureConventions(nancyConventions);
            nancyConventions.StaticContentsConventions.Add(
                StaticContentConventionBuilder.AddDirectory("scripts", @"scripts", "js")
                );
            nancyConventions.StaticContentsConventions.Add(
                StaticContentConventionBuilder.AddDirectory("css", @"css", "css")
                );
        }

        protected override void ApplicationStartup(IKernel container, IPipelines pipelines)
        {
            base.ApplicationStartup(container, pipelines);
        }


        protected override IKernel CreateRequestContainer(Nancy.NancyContext context)
        {
            return kernel;
        }
    }


class Program
{  
        public static void Main(string[] args)
       {        
        var options = new StartOptions();
        options.Urls.Add(this.config.HostUrl.AbsoluteUri);
        using(WebApp.Start(options,
            builder =>
            {
                builder.Properties["host.AppName"] = "Self host";
                builder.Properties["host.AppMode"] = "development";
                builder.MapSignalR("/signalr",
                    new HubConfiguration
                    {
                        EnableJSONP = true,
                        EnableJavaScriptProxies = true,
                        Resolver = new DefaultDependencyResolver()
                    });
                builder.UseErrorPage();
                builder.UseNancy();
            })
          { Console.ReadLine();}
      }
    }

The call to UseNancy() throws the following error. Ninject is not able to resolve IRouteResolverTrie.

System.InvalidOperationException was unhandled

Message=Something went wrong when trying to satisfy one of the dependencies during composition, make sure that you've registered all new dependencies in the container and inspect the innerexception for more details.

Request for INancyEngine

Suggestions:

Ensure that you have defined a binding for IRouteResolverTrie.
If the binding was defined in a module, ensure that the module has been loaded into the kernel.
Ensure you have not accidentally created more than one kernel.
If you are using constructor arguments, ensure that the parameter name matches the constructors parameter name.
If you are using automatic module loading, ensure the search path and filters are correct.
