Global handler for model state errors

Question

We are creating MVC3 applications. We are using default editors and model state validation. We need to log application errors, but we prefer to make it by some kind of a global handler. We have a handler for unhandled exceptions, but we also want to log model state errors.

The question is: Where can we attach our logger to log such errors? Can we somehow override ModelState or detect situation when model served to view has model errors?

Maybe try checking out global filters as shown here: http://stackoverflow.com/questions/4842721/asp-net-mvc-3-handleerror-global-filter-always-shows-iis-status-500-page — Alex H, Aug 25 '11 at 08:23

Global filters will most likely be your best way to go. More from SO here: asp.net mvc 3 handleerror global filter always shows IIS status 500 page

Or checkout the msdn doc here: http://msdn.microsoft.com/en-us/library/gg416513(v=vs.98).aspx

Create a attribute to handle error and register it in the controller,

public class ErrorHandlerAttribute : HandleErrorAttribute
    {
        public override void OnException(ExceptionContext exceptionContext)
        {
           LogManager.GetLogger("somelogger").Error(exceptionContext.Exception.Message,exceptionContext.Exception);
            base.OnException(exceptionContext);
        }
    }

register it in the controller like this,

[EwmsErrorHandler(ExceptionType = typeof(base type of exception to handle), View = view to redirect)]
public class MyController : Controller
{
<controller code>
}

I know how to handle exceptions... the problem was to handle when model state is invalid... — Łukasz W., Aug 25 '11 at 10:49
