Asp.Net MVC: Error Handling Ajax Partial Views

During the second year of my job as a Application Developer I was ask to design some type of error handler to properly display partial views that were pulled in via ajax. What was currently happening was that partial errors were being displayed as full page error and causing other issues when Jquery libraries being loaded in twice.

Questions
  • Could you create a partial view and full view error page for display appropriately for both? So in the case where it was a partial view error the error page would simply display inside the partial.
  • Is there a way to determine by ActionResult type the error handler needed?
My Solution
 ///This is an attribute for PartialViews. It handles any errors and override the basecontroller's OnExpection method. 
    public class PartialErrorAttribute : HandleErrorAttribute
    {
        ///Similar setup to the base controller OnExpection method, but has a special partial view error page called _ErrorPartial".<summary>        ///This OnException will happen before the base controller OnException and tested for an unhandled exception when it reachs the base 
        /// controller.</summary>
        /// <param name="filterContext" />This filter includes the stack trace as well as any inner messages.
        public override void OnException(ExceptionContext filterContext)
        {
          if (filterContext.ExceptionHandled) return;
            HttpException hE = filterContext.Exception as HttpException;
            MasterModel master = new MasterModel()
             if (filterContext.Exception.InnerException != null)
             {
               master.Exception = filterContext.Exception.InnerException;
             }
             else
             {
               master.Exception = filterContext.Exception;
             }

             ///I believe this is the correct way of doing things...
             var path = filterContext.Controller.ControllerContext.RequestContext.HttpContext.Request.Url.PathAndQuery;
             var IPAddress = filterContext.Controller.ControllerContext.RequestContext.HttpContext.Request.UserHostAddress;
             var referer = filterContext.Controller.ControllerContext.RequestContext.HttpContext.Request.UrlReferrer.AbsolutePath;
             using (var ssc = new SiteService.SiteServiceClient())
             {
                 ssc.LogError(path, "Partial", IPAddress, referer, master.UserID, master.Global.CartCookieID, master.Exception.StackTrace, master.Exception.Message, filterContext.Controller.ControllerContext.RequestContext.HttpContext.Request.UserAgent, master.Global.PriorityCode);
             }
             filterContext.ExceptionHandled = true;
             filterContext.Result = new PartialViewResult { ViewName = "_ErrorPartial", ViewData = new ViewDataDictionary(master) };

            base.OnException(filterContext);
            }
        }

Mongodb Cheatsheet

This cheat sheet is based on the latest version of mongodb, which initial had setup and didn't encounter any problems. However that all changed when I was working remote and forgot I disabled the port no my network, rather than with the server. So I went pointing around where I didn't need to and ended up messing things up. The Best tutorial out there is of course on digital ocean for my setup on ubuntu 16.04 , this articles isn't so much about getting setup. I just wanted to include it because I found myself looking back at it to see if I missed a step. Bugs/Problems Now comes all the messed up things I found and had to deal with. firewall - Port seems to be open, but connection refused try using 0.0.0.0 in the bin_ip for the /etc/mongo.conf try sudo ufw disable and check to see if it works without the firewall (probably still wont but worth a shot), then just sudo ufw enable. Make sure port 27017 is open. Then check this  linux - Connection refused to MongoDB e...

Installing Windows on Acer chromebook 15 cb3-532

Much of my notes are just small problems I faced (what's new!) haha. Either way this was a really fun project to do for a friend and I got excited once I research all the information. You can find instruction videos but what helped me the most was the coolstar website. Sadly they don't have parameters in the url so I can link the machine I used in this article. -  https://coolstar.org/chromebook/windows-install.html Scared of messing with the bios? Don't be!    So you need to first remove the screw to put a legacy bios on the machine. Its easy to backup the chrome os one and with the same steps to change it. You can go back in and revert to the chrome version bios. Its that last part that had me worried and its very easy to do.  Problems getting into Developer Mode?   Follow the instructions to the letter, during the step to disable the OS verification, press Ctrl-D to boot into os. If you hear two beeps I would go back to set one. I got in a loo...
