I have created one demo in mvc 5 and now I need to create one custom filter in my demo. I have used mvc 5.
I need to check every time what method is execute like is a ajax call or action method call in mvc.
Here I have write like this code in my class.
public class UserSession
: System.Web.Http.Filters.ActionFilterAttribute
{
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
var session = filterContext.HttpContext.Session;
if (ApplicationSession.IsSessionAlive)
return;
if (filterContext.HttpContext.Request.IsAjaxRequest())
{
var ajaxRedirectTarget = new RouteValueDictionary { { "action", "FailAuthenticationAjax" }, { "controller", "Home" } };
filterContext.Result = new RedirectToRouteResult(ajaxRedirectTarget);
}
else
{
var redirectTarget = new RouteValueDictionary { { "action", "Login" }, { "controller", "Account" } };
filterContext.Result = new RedirectToRouteResult(redirectTarget);
}
}
}
but I got error like this UserSession.OnActionExecuting(ActionExecutingContext): no suitable method found to override
After I have put this class on my controller like this.
[UserSession]
public class DashboardController
{
}
any one know how to fixed this issue in mvc 5?

I'm trying to create a connection between 2 existing entities PropertyGroup and CustomFieldSet. Use-case is irrelevant.
So I created an EntityExtension:
public function extendFields(FieldCollection $collection): void
{
$collection->add(
(new ManyToOneAssociationField('customFieldSet', 'custom_field_set', CustomFieldSetDefinition::class))
);
}
public function getDefinitionClass(): string
{
return PropertyGroupDefinition::class;
}
And override the administration component to also include this association when loading the entity:
Component.override('sw-property-detail', {
methods: {
loadEntityData() {
this.isLoading = true;
const criteria = this.defaultCriteria;
criteria.addAssociation('customFieldSet', new Criteria(1, 500));
this.propertyRepository.get(this.groupId, Shopware.Context.api, criteria)
.then((currentGroup) => {
this.propertyGroup = currentGroup;
this.isLoading = false;
}).catch(() => {
this.isLoading = false;
});
}
}
});
(I tried to override defaultCriteria but that didn't work because of this.$super being unable to access computed properties).
But it keeps saying FRAMEWORK__ASSOCIATION_NOT_FOUND. I debugged the EntityDefinition and it seems that this extension is not even loaded.
I checked if my EntityExtension is loaded in the Symfony container and it is, but it seems that it doesn't reach the entity definition.
The EntityExtension seems to be missing the addition of a FkField inside the function extendFields:
public function extendFields(FieldCollection $collection): void
{
$collection->add(
(new FkField('custom_field_set', 'customFieldSetId', CustomFieldSetDefinition::class)),
);
$collection->add(
(new ManyToOneAssociationField('customFieldSet', 'custom_field_set', CustomFieldSetDefinition::class))
);
}
A new use statement has to be added for the FkField:
use Shopware\Core\Framework\DataAbstractionLayer\Field\FkField;
How do you model bind an array from the URI with GET in ASP.NET Core 1 Web API (implicitly or explicitly)?
In ASP.NET Web API pre Core 1, this worked:
[HttpGet]
public void Method([FromUri] IEnumerable<int> ints) { ... }
How do you do this in ASP.NET Web API Core 1 (aka ASP.NET 5 aka ASP.NET vNext)? The docs have nothing.
The FromUriAttribute class combines the FromRouteAttribute and FromQueryAttribute classes. Depending the configuration of your routes / the request being sent, you should be able to replace your attribute with one of those.
However, there is a shim available which will give you the FromUriAttribute class. Install the "Microsoft.AspNet.Mvc.WebApiCompatShim" NuGet package through the package explorer, or add it directly to your project.json file:
"dependencies": {
"Microsoft.AspNet.Mvc.WebApiCompatShim": "6.0.0-rc1-final"
}
While it is a little old, I've found that this article does a pretty good job of explaining some of the changes.
Binding
If you're looking to bind comma separated values for the array ("/api/values?ints=1,2,3"), you will need a custom binder just as before. This is an adapted version of Mrchief's solution for use in ASP.NET Core.
public class CommaDelimitedArrayModelBinder : IModelBinder
{
public Task BindModelAsync(ModelBindingContext bindingContext)
{
if (bindingContext.ModelMetadata.IsEnumerableType)
{
var key = bindingContext.ModelName;
var value = bindingContext.ValueProvider.GetValue(key).ToString();
if (!string.IsNullOrWhiteSpace(value))
{
var elementType = bindingContext.ModelType.GetTypeInfo().GenericTypeArguments[0];
var converter = TypeDescriptor.GetConverter(elementType);
var values = value.Split(new[] { "," }, StringSplitOptions.RemoveEmptyEntries)
.Select(x => converter.ConvertFromString(x.Trim()))
.ToArray();
var typedValues = Array.CreateInstance(elementType, values.Length);
values.CopyTo(typedValues, 0);
bindingContext.Result = ModelBindingResult.Success(typedValues);
}
else
{
// change this line to null if you prefer nulls to empty arrays
bindingContext.Result = ModelBindingResult.Success(Array.CreateInstance(bindingContext.ModelType.GetElementType(), 0));
}
return TaskCache.CompletedTask;
}
return TaskCache.CompletedTask;
}
}
You can either specify the model binder to be used for all collections in Startup.cs:
public void ConfigureServices(IServiceCollection services)
{
// Add framework services.
services.AddMvc().AddMvcOptions(opts =>
{
opts.ModelBinders.Insert(0, new CommaDelimitedArrayModelBinder());
});
}
Or specify it once in your API call:
[HttpGet]
public void Method([ModelBinder(BinderType = typeof(CommaDelimitedArrayModelBinder))] IEnumerable<int> ints)
ASP.NET Core 1.1 Answer
#WillRay's answer is a little outdated. I have written an 'IModelBinder' and 'IModelBinderProvider'. The first can be used with the [ModelBinder(BinderType = typeof(DelimitedArrayModelBinder))] attribute, while the second can be used to apply the model binder globally as I've show below.
.AddMvc(options =>
{
// Add to global model binders so you don't need to use the [ModelBinder] attribute.
var arrayModelBinderProvider = options.ModelBinderProviders.OfType<ArrayModelBinderProvider>().First();
options.ModelBinderProviders.Insert(
options.ModelBinderProviders.IndexOf(arrayModelBinderProvider),
new DelimitedArrayModelBinderProvider());
})
public class DelimitedArrayModelBinderProvider : IModelBinderProvider
{
public IModelBinder GetBinder(ModelBinderProviderContext context)
{
if (context == null)
{
throw new ArgumentNullException(nameof(context));
}
if (context.Metadata.IsEnumerableType && !context.Metadata.ElementMetadata.IsComplexType)
{
return new DelimitedArrayModelBinder();
}
return null;
}
}
public class DelimitedArrayModelBinder : IModelBinder
{
public Task BindModelAsync(ModelBindingContext bindingContext)
{
if (bindingContext == null)
{
throw new ArgumentNullException(nameof(bindingContext));
}
var modelName = bindingContext.ModelName;
var valueProviderResult = bindingContext.ValueProvider.GetValue(modelName);
var values = valueProviderResult
.ToString()
.Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries);
var elementType = bindingContext.ModelType.GetTypeInfo().GenericTypeArguments[0];
if (values.Length == 0)
{
bindingContext.Result = ModelBindingResult.Success(Array.CreateInstance(elementType, 0));
}
else
{
var converter = TypeDescriptor.GetConverter(elementType);
var typedArray = Array.CreateInstance(elementType, values.Length);
try
{
for (int i = 0; i < values.Length; ++i)
{
var value = values[i];
var convertedValue = converter.ConvertFromString(value);
typedArray.SetValue(convertedValue, i);
}
}
catch (Exception exception)
{
bindingContext.ModelState.TryAddModelError(
modelName,
exception,
bindingContext.ModelMetadata);
}
bindingContext.Result = ModelBindingResult.Success(typedArray);
}
return Task.CompletedTask;
}
}
There are some changes in the .NET Core 3.
Microsoft has split out the functionality from the AddMvc method (source).
As AddMvc also includes support for View Controllers, Razor Views and etc. If you don't need to use them in your project (like in an API), you might consider using services.AddControllers() which is for Web API controllers.
So, updated code will look like this:
public void ConfigureServices(IServiceCollection services)
{
services.AddControllers()
.AddMvcOptions(opt =>
{
var mbp = opt.ModelBinderProviders.OfType<ArrayModelBinderProvider>().First();
opt.ModelBinderProviders.Insert(opt.ModelBinderProviders.IndexOf(mbp), new DelimitedArrayModelBinderProvider());
});
}
I have an extremely odd error and wondered if anyone knew the reason for this.
When I create a new DataObject and TableController called Content and ContentController respectively, it doesn't register the tablecontroller and the help documentation it automatically generates has lost its styling.
I can't connect to the controller at all but all other controllers work as expected.
If I just rename it to DataController and that's just the name of the controller, not the dataobject everything works perfectly.
Is ContentController a reserved word of some kind or is this just specifically happening on my machine?
public class DataController : TableController<Content>
{
protected override void Initialize(HttpControllerContext controllerContext)
{
base.Initialize(controllerContext);
MobileContext context = new MobileContext();
DomainManager = new EntityDomainManager<Content>(context, Request, Services);
}
// GET tables/Content
public IQueryable<Content> GetAllContent()
{
return Query();
}
// GET tables/Content/48D68C86-6EA6-4C25-AA33-223FC9A27959
public SingleResult<Content> GetContent(string id)
{
return Lookup(id);
}
// PATCH tables/Content/48D68C86-6EA6-4C25-AA33-223FC9A27959
public Task<Content> PatchContent(string id, Delta<Content> patch)
{
return UpdateAsync(id, patch);
}
// POST tables/Content/48D68C86-6EA6-4C25-AA33-223FC9A27959
public async Task<IHttpActionResult> PostContent(Content item)
{
Content current = await InsertAsync(item);
return CreatedAtRoute("Tables", new { id = current.Id }, current);
}
// DELETE tables/Content/48D68C86-6EA6-4C25-AA33-223FC9A27959
public Task DeleteContent(string id)
{
return DeleteAsync(id);
}
}
An MVC project will create an application directory called Content. This will override your route mapping to the ContentController.
You can get around this if desired through changing RouteMaps and other trickery although probably the simpliest answer is to change the name of the controller...
I have a WebApi project and I am trying to add an area to it.
Is there something different that needs to be done when adding a new area to a webapi project vs a mvc4 application?
I have a simple area registration like
public class MobileAreaRegistration : AreaRegistration
{
public override string AreaName
{
get
{
return "Mobile";
}
}
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute(
"Mobile_default",
"Mobile/{controller}/{action}/{id}",
new { action = "Index", id = UrlParameter.Optional }
);
}
}
A controller like
public class BusinessDetailsController : BaseController
{
public string Index()
{
return "hello world";
}
public HttpResponseMessage Get()
{
var data = new List<string> {"Store 1", "Store 2", "Store 3"};
return Request.CreateResponse(HttpStatusCode.OK, data);
}
}
However I can never reach the api. Am I doing something stupid or is there an extra step with the webapi that needs to be done?
Your code registers an MVC route for the Area, not a Web API route.
To do that use the MapHttpRoute extension method (you'll need to add a using statement for System.Web.Http).
public override void RegisterArea(AreaRegistrationContext context)
{
context.Routes.MapHttpRoute(
name: "AdminApi",
routeTemplate: "admin/api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
context.MapRoute(
"Admin_default",
"Admin/{controller}/{action}/{id}",
new { action = "Index", id = UrlParameter.Optional }
);
}
However, Areas are not really supported OOTB in ASP.NET Web API and you'll get an exception if you have two controllers with the same name (regardless of whether they are in different areas).
To support this scenario you need to change the way that controllers are selected. You'll find an article that covers how to do this here.
In my MVC 2 project, I originally used Ninject 2 and wrote this version of the NinjectControllerFactory:
public class NinjectControllerFactory : DefaultControllerFactory
{
private IKernel kernel = new StandardKernel(new HandiGamerServices());
protected override IController GetControllerInstance(System.Web.Routing.RequestContext requestContext, Type controllerType)
{
try
{
if (controllerType == null)
{
return base.GetControllerInstance(requestContext, controllerType);
// return null;
}
}
catch (HttpException ex)
{
if (ex.GetHttpCode() == 404)
{
IController errorController = kernel.Get<ErrorController>();
((ErrorController)errorController).InvokeHttp404(requestContext.HttpContext);
return errorController;
}
else
{
throw ex;
}
}
return (IController)kernel.Get(controllerType);
}
Of most importance is the retrieval of my ErrorController, which allows me to gracefully handle a multitude of HTTP errors.
The problem is that I upgraded to the MVC 2 extension via Nuget, so a NinjectControllerFactory is already provided. Would it be possible to use my own override of GetControllerInstance? If so, how?
I do exactly this, and for precisely the same reason. In Global.asax.cs, I add this to my OnApplicationStarted override (declared virtual in NinjectHttpApplication):
ControllerBuilder.Current.SetControllerFactory(
new MyControllerFactory(ControllerBuilder.Current.GetControllerFactory()));
This means you're creating your own controller factory, but providing it with the default implementation to do the heavy lifting.
Then define your controller factory like so:
public class MyControllerFactory : IControllerFactory
{
private IControllerFactory defaultFactory;
public MyControllerFactory(IControllerFactory defaultFactory)
{
this.defaultFactory = defaultFactory;
}
public IController CreateController(RequestContext requestContext, string controllerName)
{
try
{
var controller = defaultFactory.CreateController(requestContext, controllerName);
return controller;
}
catch (HttpException e)
{
// Pasted in your exception handling code here:
if (ex.GetHttpCode() == 404)
{
IController errorController = kernel.Get<ErrorController>();
((ErrorController)errorController).InvokeHttp404(requestContext.HttpContext);
return errorController;
}
else
{
throw ex;
}
}
}
public SessionStateBehavior GetControllerSessionBehavior(RequestContext requestContext, string controllerName)
{
return defaultFactory.GetControllerSessionBehavior(requestContext, controllerName);
}
public void ReleaseController(IController controller)
{
defaultFactory.ReleaseController(controller);
}
}
As you can see, we're just using the default (Ninject) controller factory for most purposes unless it can't find the page. For obtaining the error controller, you can either pass in the kernel as you were already doing, or just call defaultFactory.CreateController using the error controller name.
