  • Two references to the same domain/entity model

    - by Sbossb
    Problem I want to save the attributes of a model that have changed when a user edits them. Here's what I want to do ... Retrieve edited view model Get domain model and map back updated value Call the update method on repository Get the "old" domain model and compare values of the fields Store the changed values (in JSON) into a table However I am having trouble with step number 4. It seems that the Entity Framework doesn't want to hit the database again to get the model with the old values. It just returns the same entity I have. Attempted Solutions I have tried using the Find() and the SingleOrDefault() methods, but they just return the model I currently have. Example Code private string ArchiveChanges(T updatedEntity) { //Here is the problem! //oldEntity is the same as updatedEntity T oldEntity = DbSet.SingleOrDefault(x => x.ID == updatedEntity.ID); Dictionary<string, object> changed = new Dictionary<string, object>(); foreach (var propertyInfo in typeof(T).GetProperties()) { var property = typeof(T).GetProperty(propertyInfo.Name); //Get the old value and the new value from the models var newValue = property.GetValue(updatedEntity, null); var oldValue = property.GetValue(oldEntity, null); //Check to see if the values are equal if (!object.Equals(newValue, oldValue)) { //Values have changed ... log it changed.Add(propertyInfo.Name, newValue); } } var ser = new System.Web.Script.Serialization.JavaScriptSerializer(); return ser.Serialize(changed); } public override void Update(T entityToUpdate) { //Do something with this string json = ArchiveChanges(entityToUpdate); entityToUpdate.AuditInfo.Updated = DateTime.Now; entityToUpdate.AuditInfo.UpdatedBy = Thread.CurrentPrincipal.Identity.Name; base.Update(entityToUpdate); }

  • Session vs singleton pattern

    - by chobo
    Hi, I have a web application where I would like to pull user settings from a database and store them for Global access. Would it make more sense to store the data in a Singleton, or a Session object? What's the difference between the two? Is it better to store the data as an object reference or break it up into value type objects (ints and strings)? Thanks!

  • FormsAuthentication AuthCookie data type

    - by FreshCode
    Does the original data type of the username string in a call to FormsAuthentication.SetAuthCookie(...) make any difference with regards to security or code maintainability? As I understand it, the cookie is encrypted and used to identify a user on each request. I'm curious whether it should affect the design of the primary key on my Users table in my database, eg. Guid vs int or a unique username string.

  • When clicking on ajax.actionlink in its oncomplete function I can't update the html of a div whith requested data

    - by Milka Salkova
    In one partial view I've got some ajax.ActionLinks which when clicked update the div 'importpartupdate' (they just updates the div whith new ajax.actionLinks with other routevalues). The problem is that when this update is competed I have to update another div - depending on which link is clicked . That's why in my OnComplete function of my ajax.ActionLink I make an ajax request to the action'GridViewLanguage' which returns me the partial view which should uodate this other div which claass .floatLanguage. So the first time when I click a link eeverything works correctly and my two divs are correctly updated. But the second time I click a new link it seems the the floatlanguuage div is not updated like somehow the browser is caching the previous info I don't know. \i tried with cache:false- nothing worked. @model MvcBeaWeb.GroupMenu <nav class="sidebar-nav"> <div class="divLeftShowMenu"> <ul> @{ if (Model != null) { foreach (MvcBeaDAL.WebServiceBeaMenu item in Model.MenuLeft) { <li> @Ajax.ActionLink(@item.SpecialWord, "ImportShow", new { id = Model.LanguageName, menuID = item.ID, articlegroupID = item.ArticlegroupID, counter = 1 }, new AjaxOptions { UpdateTargetId = "importPartUpdate", HttpMethod = "GET", InsertionMode = InsertionMode.Replace, OnComplete = "success("[email protected]+")" }, new { id=item.ID}) </li> } } } </ul> </div> </nav> <script> function success(ids) { var nocache = new Date().getTime(); jQuery.ajax({ url: '@Url.Action("GridLanguageView")/?menuID='+ids }).done(function (data) { $(".floatLanguage").replaceWith(data); alert(data); }); } </script>

  • a potentially dangerous request.form value was detected but validateinput(false) not working

    - by tonybolding
    I have installed VS2010 and MVC2 and testing a simple form using tinyMCE. When I post the contents of the textarea in tinyMCE I get the dreaded YSD and the message "a potentially dangerous....." No problem I thought - seen this before so I put the ValidateInput(false) on the controller but no joy - I still get the error. page code in edit.aspx is: <% using (Html.BeginForm()){ % <!-- Gets replaced with TinyMCE, remember HTML in a textarea should be encoded --> <textarea id="elm1" name="mceText" rows="15" cols="80" style="width: 80%"> &lt;p&gt; This is some example text that you can edit inside the &lt;strong&gt;TinyMCE editor&lt;/strong&gt;. </textarea> <br /> <input type="submit" name="save" value="Submit" /> <input type="reset" name="reset" value="Reset" /> <%} % and Controller action is: [AcceptVerbs(HttpVerbs.Post)] [ValidateInput(false)] public ActionResult Edit(string mceText) { return View(); } Any thoughts - (I know the code is not complete) been trying this for hours but everyone just says to use ValidateInput(false)

  • How to get and modify a property value through a custom Attribute?

    - by David G
    I want to create a custom attribute that can be used on a property like: [TrimInputString] public string FirstName { get; set; } that will be functional equivalent of private string _firstName public string FirstName { set { _firstName = value.Trim(); } get { return _firstName; } } So basically every time property is set the value will be trimmed. How do I get the value parsed, modify that value and then set the property with the new value all from within the attribute? [AttributeUsage(AttributeTargets.Property)] public class TrimInputAttribute : Attribute { public TrimInputAttribute() { //not sure how to get and modify the property here } }

    I would like to outsource pieces of a new web application/site. I don't want one company working on the whole project because they can easily change a few things and sell the software to someone else. I will be using a freelenace website like elance or guru. A buddy of mine has given me this advice but he did not say how this can be done. Any ideas on how to go about this?

  • @ExceptionHandler doesn't handle the thrown exceptions

    - by Javi
    Hello, I have a method in my controller which will handle the exceptions thrown by the application. So I have a method like this one. @Controller public class ExceptionController { @RequestMapping(value="/error") @ExceptionHandler(value={Exception.class, NullPointerException.class}) public String showError(Exception e, Model model){ return "tiles:error"; } } And to try I if it works I throw a NullPointerException in another method in other method controller: boolean a = true; if(a){ throw new NullPointerException(); } After the exception is thrown it is printed in the JSP, but it doesn't go throw my showError() method (I've set a breakpoint there and it never enters). showError() method will catch the exception and will show different error pages depending on the exception type (though now it always shows the same error page). If I go to the url /error it shows the error page so the showError() method is OK. I'm using Spring 3. What can be the problem? Thanks.

I have another ActionResult just like this except taking in an int id as parameter and it works fine with the first url format.

  • How can I detect if a request and response cookies are different?

    - by Malcolm Frexner
    I need to detect if a request cookie - value is different from a response cookie - value. Its not as easy as: if(cookiesArePresent) { bool isDifferent = HttpContext.Current.Response.Cookies[".ASPXANONYMOUS"].value == HttpContext.Current.Response.Cookies[".ASPXANONYMOUS"].value; } But I read that changing the Response.Cookies changes the Request.Cookies. That would mean they are always the same if HttpContext.Current.Response.Cookies[".ASPXANONYMOUS"] was changed. Is there an easy way around this? http://chance.lindseydev.com/2009/04/aspnet-httprequestcookies-and.html

  • Problem with nhibernate join

    - by MexicanHacker
    I'm trying to do a join like this using fluent nhibernate: Id(x => x.Id); Map(x => x.SourceSystemRecordId,"sourceSystemRecord_id"); Then Join("cat.tbl_SourceSystemRecords", SourceSystemRecords); But, it seems I don't have a way to specify the column I want to join with from the first table, in this case I need to join on SourceSystemRecordId and not on Id Is there any way I can specify this? I tried References() but that requires me to create an object for this relationship, what I need is to aggregate the columns in sourcesystem records to the ones in the main table.

  • MVC3 - render view that is not a method in a controller

    - by scoo-b
    I don't know how to best describe my requirement, but here goes. I'm trying to render a view from the following controller/model in a nopCommerce application: CustomerController.cs snippet: [NonAction] protected CustomerNavigationModel GetCustomerNavigationModel(Customer customer) { var model = new CustomerNavigationModel(); model.HideAvatar = !_customerSettings.AllowCustomersToUploadAvatars; model.HideRewardPoints = !_rewardPointsSettings.Enabled; model.HideForumSubscriptions = !_forumSettings.ForumsEnabled || !_forumSettings.AllowCustomersToManageSubscriptions; model.HideReturnRequests = !_orderSettings.ReturnRequestsEnabled || _orderService.SearchReturnRequests(customer.Id, 0, null).Count == 0; model.HideDownloadableProducts = _customerSettings.HideDownloadableProductsTab; model.HideBackInStockSubscriptions = _customerSettings.HideBackInStockSubscriptionsTab; return model; } CustomerNavigationModel.cs: public partial class CustomerNavigationModel : BaseNopModel { public bool HideInfo { get; set; } public bool HideAddresses { get; set; } public bool HideOrders { get; set; } public bool HideBackInStockSubscriptions { get; set; } public bool HideReturnRequests { get; set; } public bool HideDownloadableProducts { get; set; } public bool HideRewardPoints { get; set; } public bool HideChangePassword { get; set; } public bool HideAvatar { get; set; } public bool HideForumSubscriptions { get; set; } public CustomerNavigationEnum SelectedTab { get; set; } } public enum CustomerNavigationEnum { Info, Addresses, Orders, BackInStockSubscriptions, ReturnRequests, DownloadableProducts, RewardPoints, ChangePassword, Avatar, ForumSubscriptions } MyAccountNavigation.cshtml snippet: @model CustomerNavigationModel @using Nop.Web.Models.Customer; @if (!Model.HideInfo) { <li><a href="@Url.RouteUrl("CustomerInfo")" class="@if (Model.SelectedTab == CustomerNavigationEnum.Info) {<text>active</text>} else {<text>inactive</text>}">@T("Account.CustomerInfo")</a></li>} Views: @Html.Partial("MyAccountNavigation", Model.NavigationModel, new ViewDataDictionary()) I am aware that it is unable to render MyAccountNavigation because it doesn't exist in the controller. However, depending on which page the syntax is placed it works. So is there a way to achieve that without changing the code in the controller? Thanks in advance.

  • Pass 2-dimensional array trough view

    - by Mikael
    Hi, I'm trying to print a 2-dimensional array but can't figure it out. My controller uses this code: public ActionResult Test(string str) { DateTimeOffset offset = new DateTimeOffset(DateTime.Now); offset = offset.AddHours(-5); string[,] weekDays = new string[7,2]; for (int i = 0; i < 7; i++) { weekDays[i,0] = String.Format("{0:yyyy-MM-dd:dddd}", offset); //Date weekDays[i,1] = String.Format("{0:dddd}", offset); //Text offset = offset.AddHours(24); } weekDays[0,1] = "Today"; ViewData["weekDays"] = weekDays; return View(); } Now I wan't to print this array of weekdays as a dropdown-list and i thought this would work: <% foreach (var item in (string[,])ViewData["weekDays"]) { %> <option value=" <%= item[0] %> "> <%= item[1] %> </option> <% } %> But that's not the case, this code output just the first char of the string. So anyone got a suggestion? Thanks! /M
