    Resolved [RESOLVED] What are those errors/How do I fix them

    Hi,

    I finished my advanced C# case study for school although, when I click on either the "Create new" or "Remove from cart" links I receive the following error:

    Server Error in '/' Application.
    The resource cannot be found.
    Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.

    Requested URL: /ShoppingCart/RemoveFromCart/116

    Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.225

    I take it that the above message is referring to the ShoppingCartController and the "RemoveFormCart" is the method is is referring to? What about the 116? However, checking the "Controllers" folder there is a file called "ShoppingCartController.cs" it with a method RemoveFromCart inside the file.

    asp Code:
    1. //AJAX: /ShoppingCart/RemoveFromCart/5
    2.         [HttpPost]
    3.         public ActionResult RemoveFromCart(int id)
    4.         {
    5.             //Remove the item from the cart
    6.               var cart = ShoppingCart.GetCart(this.HttpContext);
    7.  
    8.               //Get the name of album to display the confirmation
    9.               string albumName = StoreDB.Carts.Single(item => item.RecordId == id).Album.Title;
    10.  
    11.             //Remove from cart. Removing all for simplicity
    12.               cart.RemoveFromCart(id);
    13.  
    14.             //Display the confirmation message
    15.             var results = new ShoppingCartRemoveViewModel
    16.             {
    17.               Message = Server.HtmlEncode(albumName) + " has been removed from your shopping cart.",
    18.               CartTotal = cart.GetTotal(),
    19.               CartCount = cart.GetCount(),
    20.               DeleteId = id
    21.             };
    22.             return Json(results);
    23.         }

    Here is the shoppingcart index page:

    asp Code:
    1. <&#37;@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<IEnumerable<MvcMusicStore.ViewModels.ShoppingCartViewModel>>" %>

    12.  
    13. <script type="text/javascript">
    14.     function handleUpdate(context) {
    15.         //Load and deserialize the returned JSON data
    16.         var json = context.get_data();
    17.         var data = Sys.Serialization.JavaScriptSerializer.deserialize(json);
    18.  
    19.         //Update the page elements
    20.         $('#row-' + data.DeleteId).fadeOut('slow');
    21.         $('#cart-status').text('Cart(' + data.CartCount + ')');
    22.         $('#update-message').text(data.Message);
    23.         $('#cart-total').text(data.CartTotal);

    55.     </td>
    56.     </tr>
    57.     <% } %>
    58.     <tr>
    59.     <td>Total</td>
    60.     <td></td>
    61.     <td></td>
    62.     <td id="cart-total">
    63.     <%: cart.CartTotal %>

    65.     </tr>
    66.     </table>
    67.  
    68.     <p>

    70.     </p>
    71.  
    72. </asp:Content>

    So what exactly is it saying it can not find and how do I fix it?

    Thanks,


    Nightwalker

    Re: What are those errors/How do I fix them

    Can you post your routes table? Or, indeed, write a test that ensures that URL maps to the expected controller/action? Because you're not generating the link from the controller, it's probably a mismatch there.

    Re: What are those errors/How do I fix them

    Can't download the project for restrictions, but are you sure the RemoveFromCart controller has a corresponding view defined?

    The only other problem I can think of right now is the path is incorrect. However I am assuming you have already checked it.

    Re: What are those errors/How do I fix them

    Well, I solved the above errors by rewriting the shopping cart index page. Although, now I have another problem:

    Server Error in '/' Application.
    The current request for action 'LogOn' on controller type 'AccountController' is ambiguous between the following action methods:
    System.Web.Mvc.ActionResult LogOn(MvcMusicStore.Models.LogOnModel, System.String) on type MvcMusicStore.Controllers.AccountController
    System.Web.Mvc.ActionResult Logon(MvcMusicStore.Models.LogOnModel, System.String) on type MvcMusicStore.Controllers.AccountController

    when I try to login to the site.

    Edit:

    Never mind! I solved that problem too. I just copied the account login forms, model, etc that I was given back into my project and it fixed the problem.

    Re: [RESOLVED] What are those errors/How do I fix them

    Hi there. I'm having the same problem of removing from cart. But i'm having this issue on my production server. On my localhost, it is working fine.

    Anyway, in your shopping cart controller line 12, shouldn't it be like below?

    int itemCount = cart.RemoveFromCart(id);

    I understand you have fixed your problem. Any workaround that you can suggest me to accomplish this? Was your site running on localhost or an online server when you developed this?

    Re: [RESOLVED] What are those errors/How do I fix them

    Hi again, sorry I missed line 20 on my previous post.

    Line 12; int itemCount = cart.RemoveFromCart(id);
    Line 20; ItemCount = itemCount,

    It looks like you had two actions with the same name and parameter sets in the controller.

    No, I have only tested the site on the local host not using an online-server.
