I have created the following Custom ActionFilter, when I try to access the Model
in the following code, it is null:
public class CustomPermissionCheckAttribute : ActionFilterAttribute
{
public override void OnActionExecuting(ActionExecutingContext context)
{
OrganisationBaseController orgBaseController = context.Controller as Controller;
var vm = ((Controller)context.Controller).ViewData.Model as MyViewModel; // null
// check if current user has permission to vm.OrganisationId
base.OnActionExecuting(context);
}
}
I am trying to understand why the Model
is null? According to ASP.NET MVC Lifecycle , ActionFilters are executed after Model Binder, so I am not sure why the Model is not available?
This is how I am register the above Action Filter:
[HttpPost]
[CustomPermissionCheck]
public ActionResult UpdateBranch(MyViewModel myViewModel)
{
if (ModelState.IsValid)
{
// so something
}
return View();
}
Could try this to access the request model:
MyViewModel vm = context.ActionParameters.Values.OfType<MyViewModel>().SingleOrDefault();
