How to inject a service with Ninjects into a selfmade RoleProvider class?
While implementing the Roleprovider so that it gets the roles from a database. I keep getting a object no instance of... exception.
As it turns out ninject does not inject my service .
I tried putting the attribuut on top of the property no succes. I tried adding a constructor but then im getting a yellow screen of death telling me there should be a parameterless constructor
The code
Public Class AnipRolProvider
Inherits RoleProvider
'this service needs to get initialized
Private _memberhip As IMemberschipService
Sub New()
'only this constructor is called by asp by default
End Sub
Sub New(memberschipservice As IMemberschipService)
'this constructor should be called but how ?
_memberhip = memberschipservice
End Sub
the only method i need
Public Overrides Function GetRolesForUser(username As String) As String()
If String.IsNullOrEmpty(username) Then
Throw New ArgumentException("username is nothing or empty.", "username")
End If
Return _memberhip.开发者_Go百科GetRolesForUser(username)
End Function
How do i implement ninjects so that role provider team up with the ninja?
Additional information :
<roleManager enabled="true" defaultProvider="AnipRoleProvider">
<providers>
<clear/>
<add name="AnipRoleProvider" type="Anip.Core.AnipRolProvider" />
</providers>
</roleManager>
in my web.config there is a reference to aniproleprovider.
offtopic-sidenote : while copying these snipsets i should learn to write better names!
You have to register your IMembershipService in the global.ascx, don't know how to do this in VB put in c# it looks like this :
kernel.Bind<IMembershipService>().To<MembershipService>().InRequestScope();
using System;
using System.Collections.Generic;
using System.Security.Principal;
using System.Web;
using System.Web.Mvc;
using System.Web.Routing;
using System.Web.Security;
using Domain.Interfaces;
using Domain.Models;
using Domain.Storage;
using Domain.Services;
using Ninject;
using Ninject.Syntax;
using WebApp.Controllers;
using WebApp.Mailers;
using WebApp.ModelBinders;
namespace WebApp
{
public class MvcApplication : NinjectHttpApplication
{
public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
filters.Add(new HandleErrorAttribute());
}
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
}
protected override IKernel CreateKernel()
{
var kernel = new StandardKernel();
kernel.Load(Assembly.GetExecutingAssembly());
kernel.Bind<ISession>().To<MongoSession>().InRequestScope();
kernel.Bind<IAuthenticationService>().To<AuthenticationService>().InRequestScope();
kernel.Bind<IMailer>().To<Mailer>().InRequestScope();
kernel.Bind<IFileProvider>().To<MongoFileProvider>().InRequestScope();
return kernel;
}
protected override void OnApplicationStarted()
{
base.OnApplicationStarted();
AreaRegistration.RegisterAllAreas();
RegisterGlobalFilters(GlobalFilters.Filters);
RegisterRoutes(RouteTable.Routes);
}
}
