ninject / ninject.web.mvc

extension for ninject providing integration with ASP.NET MVC

Ninject.Web.Mvc

This extension allows integration between the Ninject and ASP.NET MVC projects. To use it, just make your HttpApplication (typically in Global.asax.cs) extend NinjectHttpApplication:

public class YourWebApplication : NinjectHttpApplication
{
  public override void OnApplicationStarted()
  {
    // This is only needed in MVC1
    RegisterAllControllersIn("Some.Assembly.Name");
  }

  public override IKernel CreateKernel()
  {
    return new StandardKernel(new SomeModule(), new SomeOtherModule(), ...);
    
    // OR, to automatically load modules:
    
    var kernel = new StandardKernel();
    kernel.AutoLoadModules("~/bin");
    return kernel;
  }
}

Once you do this, your controllers will be activated via Ninject, meaning you can expose dependencies on their constructors (or properties, or methods) to request injections.

ninject.web.mvc's Issues

Controller level filter stops global filter from executing (MVC3, 2.2+)

A global filter is not executing when a controller contains a controller level filter.

Tried with ninject 2.3.0.6 and 2.2.1.1

To reproduce

    [AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, Inherited = true, AllowMultiple = true)]
    public class AlphaAttribute : Attribute {}

    public class FilterAlpha : IActionFilter
    {
        public void OnActionExecuting(ActionExecutingContext filterContext) {}

        public void OnActionExecuted(ActionExecutedContext filterContext)
        {
            filterContext.Controller.ViewData["alpha"] = "here";
        }
    }

    public class FilterBeta : IActionFilter
    {
        public void OnActionExecuting(ActionExecutingContext filterContext) {}

        public void OnActionExecuted(ActionExecutedContext filterContext)
        {
            filterContext.Controller.ViewData["beta"] = "here";
        }
    }

    [Alpha]
    public class WithController : Controller
    {
        public ActionResult Index()
        {
            return View();
        }
    }

    public class WithoutController : Controller
    {
        public ActionResult Index()
        {
            return View();
        }
    }

Registration

            kernel.BindFilter<FilterAlpha>(FilterScope.Controller, 0)
                .WhenControllerHas<AlphaAttribute>();

            kernel.BindFilter<FilterBeta>(FilterScope.Global, 0);

Views

<p>Alpha? @ViewData["alpha"]</p>
<p>Beta? @ViewData["beta"]</p>

How to Inject EF Core in MVC .Net Framework 4.6.1

I am having trouble injecting EF Core into my MVC Web application (framework 4.6.1). I have a SO question here but to summerize:
I am binding the DbContext to itself in transient scope but it seems that the context instance is being reused and then it fails because EF has closed the connections. In the controller method I make a call to the db in one repository which works and then I make a call to the db in a different repository which fails and throws an exception.

No database provider has been configured for this DbContext. A provider can be configured by overriding the DbContext.OnConfiguring method or by using AddDbContext on the application service provider. If AddDbContext is used, then also ensure that your DbContext type accepts a DbContextOptions object in its constructor and passes it to the base constructor for DbContext.

Code examples are in the SO question.

Add ActionResult invoker

I noticed that Ninject.Web.Mvc has an ActionFilter invoker, to inject dependencies into an ActionFilter. Is it possible to do the same for ActionResults?

Application_End instead of Application_Stop?

I could be mistaken, but shouldn't "mvc2/src/Ninject.Web.Mvc/NinjectHttpApplication.cs" line 58 be Application_End and not Application_Stop?

I've looked at both http://msdn.microsoft.com/en-us/library/ms178473.aspx and http://msdn.microsoft.com/en-us/library/bb470252.aspx, and I haven't found anything referring to Application_Stop.

Thanks,
Steven

Ninject MVC2 library is missing RegisterAllControllers in methods on NinjectHttpApplication

as the title says

Strong Name

Would it be possible to sign this with a strong name with the same key used for Ninject core?

Error activating IFilterProvider using binding from IFilterProvider to NinjectFilterAttributeFilterProvider

A cyclical dependency was detected between the constructors of two services. Activation path: 1) Request for IFilterProvider

I keep getting this in a production server after a few hours of flawless execution. I don't see any other exceptions in the elmah logs and my current guess is that the server is reloading/restarting the app somehow and this leads to the exceptions. Of course, once those appear, the whole app is unusable.

I'm using Ninject 2.2.0.0 and Ninject.Web.Mvc 2.2.0.3 and extend NinjectHttpApplication in my Global.asax.cs (Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.1; ASP.MVC 3)

Here's the full trace

[ActivationException: Error activating IFilterProvider using binding from IFilterProvider to NinjectFilterAttributeFilterProvider
A cyclical dependency was detected between the constructors of two services.

Activation path:
  1) Request for IFilterProvider

Suggestions:
  1) Ensure that you have not declared a dependency for IFilterProvider on any implementations of the service.
  2) Consider combining the services into a single one to remove the cycle.
  3) Use property injection instead of constructor injection, and implement IInitializable
     if you need initialization logic to be run after property values have been injected.

Asynchronous action methods not working

NinjectControllerFactory.CreateActionInvoker creates a ControllerActionInvoker-Subclass (Ninject.Web.Mvc.NinjectActionInvoker). But for asynchronous action methods to work correctly an AsyncControllerActionInvoker-Subclass is needed.

I have a solution that works for me - but it feels "not DRY". I created an AsyncNinjectActionInvoker that inherits from AsyncControllerActionInvoker - with the same GetFilters-Method as the NinjectActionInvoker.

Presumably it would be better to make NinjectActionInvoker inherit from AsyncControllerActionInvoker - but I was not sure whether that brings some overhead to all synchronous action methods.

UPDATE: Meanwhile I decided to undo my last changes and just change the NinjectActionInvoker to inherit from AsyncControllerActionInvoker.

Sequence contains no elements

MVC4 and MVC 4 Web API

Are there any rough timescales for a webapi implementation for ninject? We are currently considering implementing ninject on a new project and in order to assess if ninject can be included in a suitable timeframe it would be helpful to know if it is planned or if there is a workaround. The Wiki link implies this functionality is not yet present.

FilterBinding Request/Explanation

Is there a reason why the fluent filter binding interface does not support the following syntax? (Reworded: I'm I being stupid by wishing the following was supported?)

kernel.BindFilter<CustomAuthorizationFilter>(FilterScope.Global, 0).UnlessActionMethodHas<AllowAnonymousAttribute>();

type or assembly bootstrapper is unknown

i have an mvc site thats used ninject (not sure which version) via the global.asax and the application start method.
i saw the new ninject packages in nuget and so i installed those.
everything looks great, it adds all the files, but it won't compile
the app_start\NinjectMVC3.cs has a type "bootstrapper" that is unknown.
i'm missing a reference or something, but i don't know where to start looking.
the project is referencing ninject and ninject.mvc.

Filters not firing for MVC Area

Hi

Been working on this for two days now without luck. Does anyone know why the filters (in this case the UnitOfWorkFilter) are not firing for the controllers within an MVC Area. Everything else seems to be working ok.

Binding in: public override void Load()

Kernel.BindFilter<UnitOfWorkFilter>(FilterScope.Action, 0);

Ninject is starting using PreApplicationStartMethod rather than extending HttpApplication. Could this be the cause?

[assembly: WebActivator.PreApplicationStartMethod(typeof(NinjectWebCommon), "Start")]
[assembly: WebActivator.ApplicationShutdownMethod(typeof(NinjectWebCommon), "Stop")]

namespace FreeSurvey.Web.Mvc
{
    public static class NinjectWebCommon
    {
        private static readonly Bootstrapper Bootstrapper = new Bootstrapper();

        /// <summary>
        /// Starts the application
        /// </summary>
        public static void Start()
        {
            DynamicModuleUtility.RegisterModule(typeof(OnePerRequestHttpModule));
            DynamicModuleUtility.RegisterModule(typeof(NinjectHttpModule));

            Bootstrapper.Initialize(CreateKernel);

            GlobalConfiguration.Configuration.DependencyResolver = new NinjectResolver(Bootstrapper.Kernel);
            GlobalHost.DependencyResolver = new SignalRNinjectResolver(Bootstrapper.Kernel);
            ControllerBuilder.Current.SetControllerFactory(new NinjectControllerFactory(Bootstrapper.Kernel));
        }

The BindFilter is currently set up to accept System.Web.Mvc filters.

In Asp.Net MVC 4 the Web Api's filters are System.Web.Http.Filters so they can't be used.

Multiple filter of same type on Action method

I know it is supported but we have to repeat binding for filter every time we repeat filter on action method. Is there any reason that it is not supported to bind all at once.

For example:- if we have filter "A" and we want to apply it to one of action method "B" 2 times then we need to bind it twice via ninject.

Any suggestions on what may be going on?

You can't inject attributes

NinjectFilterAttributeFilterProvider is nonsense: you cannot inject dependencies into attributes.
There is exactly one instance of attribute per attribute application per appdomain, which means you will inject dependencies into the same instance over and over again, on every request.

This is fine when those dependencies are globally scoped, but not so fine when they are, say, request-scoped, which is a very common case. Even less fine if you happen to handle multiple requests at the same time, which is not just common case - it's the ONLY case. And in that case, you get yourself weird race conditions.

OnePerRequestHttpModule does not perform its cleanup work

When installing the latest nuget package (3.2.1), I noticed that disposable components in request scope were no longer properly cleaned up (Dispose() not called at request end). When downgrading to 3.2.0, all is fine. After looking at the code, it seems that MvcModule no longer inherits from GlobalKernelRegistrationModule, but directly from NinjectModule. Consequently, the kernel instance is no longer in GlobalKernelRegistration, and the MapKernels call in OnePerRequestHttpModule has no effect.
Am I missing something (some config, or module to load)? Or is it an issue in the generated code when installing the nuget package? Or possibly a bug?

MVC4 Medium Trust issue

I have hosted my website with Speedhost.in. Recently they changed the default setting for all web-apps from full to medium. I am getting a Security Exception since then. My hosting company has restricted overriding of trustlevel policy and so I cannot change the trustlevel to full again.

The security exception I am getting is more of a general exception and I am unable to think of a way to fix this. How should I decide which dll is asking for the restricted permission?

Please Update Web Activator Dependency

Hi I have been working with the creator of WebActivator closely for a new issue that arose with update to .net 4.5 using MVC. We have patched a work around in WebActivator 2.0.2, but ninject this requires 1.5.x

Can you please update ninject to use the latest WebActivator

Help: How I can change dependency based on Area In Asp.net MVC

I am very new. Just know how to use Ninject MVC3 extension. I want to change dependency based on Area. I have several DBContext for my application. I want to inject them based on Area.

Need your help. How i can achieve this. I know how to Rebind the dependency but where i have to configure this so that it rebinds dependency based on Area.

I am sorry if I posted it on wrong place.
Waiting for your help.

Dependency Injection Outside Controller (MVC 4 Web API)

I have an ApiController with the following constructor signature:

public BlazrController(BlazrDBContext dbContext, IAuthProvider authProvider, ILogger logger) { ... }

My bindings:

kernel.Bind<BlazrDBContext>().ToSelf().InRequestScope();
kernel.Bind<IHasher>().To<PasswordHasher>().InRequestScope();
kernel.Bind<IIPContextProvider>().To<DefaultIPContextProvider>().InRequestScope();
kernel.Bind<ILocationContextProvider>().To<DefaultLocationContextProvider>().InRequestScope();
kernel.Bind<ILogger>().To<FileLogger>().InRequestScope();
kernel.Bind<IAuthProvider>().To<BlazrAuthProvider>().InRequestScope();

And the IAuthProvider implementation (BlazrAuthProvider) has a constructor with signature:

public BlazrAuthProvider(BlazrDBContext dbcontext, IHasher hasher) {....}

When I run my application and navigate to a route under the ApiController above, I get the whole "No default constructor" error. I have removed the injected parameters from the constructors as to narrow down which one was causing the problem - and it was the IHasher under the BlazrAuthprovider. If I remove that from the constructor, it loads just fine.

I implemented a NinjectDependencyResolver (IDependencyResolver) as others have suggested but still can't get this to work. Am I missing something?

Also worth noting: the Controller is under it's own Web API Project and the other classes/interfaces are under a Class Library Project in the same solution.

Parameter name to WithConstructorArgumentFromControllerAttribute is not enforced

Given the following code

this.BindFilter<FooFilter>(FilterScope.Controller, order: 0)
    .WhenControllerHas<FooAttribute>()
    .WithConstructorArgumentFromControllerAttribute<FooAttribute>(parameterName, someLambda);

I've found that the parameterName passed in must not be null or empty, but as long as a type matches, it will succeed. My expectation was that it would fail to bind if it couldn't find a parameter with the proper name AND type provided. Ninject seems to prefer Constructors with more dependencies, so it's possible you could attempt to override a parameter of one constructor with less parameters but will instead override the other that may contain a non-matching name.

For example:

public class FooFilter : IFooFilter
{
    public FooFilter(IFoo f) { .. }
    public FooFilter(IFoo foo, IBar bar) { .. }
}

Specifying a constructor parameter name of "f" will still prefer the latter constructor. The parameter name seems to be ignored.

Different behaviour during debug with visual studio 2012

Hi, I encountered a strange problem when using ninject in mvc4 project.
Simply speaking, I want inject multiple IxxxRepository into controller, each IRepository constructed with IUnitOfWork implementation. IUnitOfWork implementation using InThreadScope object scope. But the problem is, everything runs as expected without vs debug, but when using VS debug and hit breakpoint in an Action, seems IxxxRepository's UnitOfWork are different.
Does VS debug will cause Ninject inject different instance into one controller although that object register with InThreadScope?
It strange because it just happened with VS debug mode....Can anybody helps?
Update: InRequestScope has same issue with VS 2012 debug.

Attempt by method 'Ninject.Web.Mvc.Validation.NinjectDataAnnotationsModelValidatorProvider.GetValidators(System Web.Mvc.ModelMetadata, System.Web.Mvc.ControllerContext, System.Collections.Generic.IEnumerable`1)' to access method 'System.Web.Mvc.DataAnnotationsModelValidator.get_Attribute()' failed.

How to get Ninject.MVC3 3.0 binary for mono

Can you tell me how can I download the binary file for the mono platform Ninject.Web.Mvc 3.

ASP.NET MVC 2 - Project Areas

The current version of this project still does not work with MVC2's project areas. If two controllers share the same name in different areas of the application (one in the default area, one outside the default area), attempting to access the conflicted-name controller in the default area will produce an ambiguity error.

I corrected this problem in a previous fork of the Ninject MVC project a long time ago, but it has yet to be merged. It is a very easy fix. http://github.com/lakario/ninject.web.mvc

cannot make ninject work

Here is my sample project [email protected]:redguardtoo/SportsStore.git, I cannot get it running.
vs2010 express+nuget+ninject,
I've read your blog at http://www.planetgeek.ch/2010/11/13/official-ninject-mvc-extension-gets-support-for-mvc3/.

Readme.md contains incomplete information

In the readme, there is a sample example:

public class YourWebApplication : NinjectHttpApplication
{  // […]
  public override IKernel CreateKernel()
  {  // […]
    var kernel = new StandardKernel();
    kernel.AutoLoadModules("~/bin");
    return kernel;
  }
}

But the AutoLoadModules extension method is not defined in this project.

WebViewPage _Layout.cshtml Injections are Null

I am Using Ninject.MVC4 in my ASP.NET MVC4 Project and I am setting Up my Bindings in the created "NinjectWebCommon.cs" file.

I've overwritten the Default View, to Inject an Permissionmanager for my Views

public abstract class MvcBaseWebViewPage<TModel> : WebViewPage<TModel>
{
    [Inject]
    public IPermissionManager PermissionManager { get; set; }
}

and then I've set the new BaseView in the Views web.config

<!--<pages pageBaseType="System.Web.Mvc.WebViewPage">-->
<pages pageBaseType="Gui.Mvc.Views.MvcBaseWebViewPage">

now I've access to the PermissionManager in My Views like

@if (PermissionManager.HasRight(RightsQsMonitor.ConfigurationTrelloVisible))
{
     <li>
      <a href="#" target="_blank">
      <i class="fa fa-trello fa-fw"></i>&nbsp;Trello</a></li>
}

that works great in all Views but for the "_Layout.cshmtl" its not working here is the "PermissionManager" Instance "Null" I think/hope its a bug or do you habe an alternate solution?

How to compile?

I'm new to git and NAnt, and I have no idea how to compile the source. I feel I've tried everything, installed NAnt, git and all I get is errors during the compilation. Tried opening the source in Visual Studio and compiling it that way, but that was also a waste of time.

How do I compile it?

And why not provide the binaries, or at least an proper solution that's possible to open in Visual Studio?

Thanks.

Please state licence type

Hi

Most of the Ninject projects are dual Apache 2.0 / Ms-PL. Please can you add a licence file to this project too?

Thanks

How may I inject something in the Global.asax ?

I'm starting a web application with MVC3 and Ninject. There is one dependency that I also need in the Global.asax file that needs to be a singleton.

I thought it should be like this:

public class MvcApplication : NinjectHttpApplication
{
IUserAuthentication _auth;

public MvcApplication()
{
    base.AuthenticateRequest += new EventHandler(MvcApplication_AuthenticateRequest);
}

protected override IKernel CreateKernel()
{
    var _kernel = new StandardKernel(new SecurityModule());
    _auth = _kernel.Get<IUserAuthentication>();

    return _kernel;
}

void MvcApplication_AuthenticateRequest(object sender, EventArgs e)
{
    _auth.ToString();
}

But then I saw that _auth is null when MvcApplication_AuthenticateRequest is called.

Then I tried like this:

public class MvcApplication : NinjectHttpApplication
{
ItUserAuthentication _auth;
IKernel _kernel;

public MvcApplication()
{
    _kernel = new StandardKernel(new SecurityModule());
    _auth = _kernel.Get<IUserAuthentication>();
    base.AuthenticateRequest += new EventHandler(MvcApplication_AuthenticateRequest);
}

protected override IKernel CreateKernel()
{
    return _kernel;
}

void MvcApplication_AuthenticateRequest(object sender, EventArgs e)
{
    _auth.ToString();
}

But now I can see that the constructor is being called several times, therefore I will have several IKernel, and I guess that singleton instances won't be so singleton in my app scope.

How should I do it? Using a static variable?

I put this question also in http://stackoverflow.com/questions/5512040/ninject-ing-a-dependency-in-global-asax
