  • Authorization in a more purely OOP style...

    - by noblethrasher
    I've never seen this done but I had an idea of doing authorization in a more purely OO way. For each method that requires authorization we associate a delegate. During initialization of the class we wire up the delegates so that they point to the appropriate method (based on the user's rights). For example: class User { private deleteMemberDelegate deleteMember; public StatusMessage DeleteMember(Member member) { if(deleteMember != null) { deleteMember(member); } } //other methods defined similarly... User(string name, string password) //cstor. { //wire up delegates based on user's rights. //Thus we handle authentication and authorization in the same method. } } This way the client code never has to explictly check whether or not a user is in a role, it just calls the method. Of course each method should return a status message so that we know if and why it failed. Thoughts?

  • MVC2 IModelBinder and parsing a string to an object - How do I do it?

    - by burnt_hand
    I have an object called Time public class Time{ public int Hour {get;set;} public int Minute {get;set;} public static Time Parse(string timeString){ //reads the ToString()'s previous output and returns a Time object } override protected string ToString(){ //puts out something like 14:50 (as in 2:50PM) } } So what I want is for the automatic model binding on the Edit or Create action to set this Time instance up from a string (i.e. feed the Parse method with the string and return the result). The reason I am doing this is that I will have a DropDownList with selectable times. The value of each option will be the parser readable string. Can anyone provide an example BindModel method from the IModelBinder interface?

  • Best place to check user authenticity in a back end module where all pages are only available to mem

    - by understack
    I've a backend module which could only be accessed by only authorized members. So I need to check authenticity for all actions and for all controllers. Currently I'm doing it inside preDispatch() functions inside controller classes. So it takes care of all the actions inside that controller. But still I've to do it for all controllers. Is there a place I could check it for all the controllers as well. So basically I want one place authenticity check for whole backend module. Can I do it in bootstrap?

  • Is it possible to return a SiteMap as a JsonResult?

    - by Paul Suart
    I've got a very simple Action on my Controller that's attempting to return my XmlSiteMap as a JsonResult: public ActionResult Index() { var nodes = SiteMap.Provider.RootNode; return new JsonResult() { Data = nodes, JsonRequestBehavior = JsonRequestBehavior.AllowGet }; } However, when I call the Action, an InvalidOperationException is thrown: "A circular reference was detected while serializing an object of type 'System.Web.SiteMapNode'." Is there a way to Json serialize a SiteMap, or indeed any object that has children of the same type?

  • How to handle model state errors in ajax-invoked controller action that returns a PartialView

    - by Robert Koritnik
    I have a POST controller action that returns a partial view. Everything seems really easy. but. I load it using $.ajax(), setting type as html. But when my model validation fails I thought I should just throw an error with model state errors. But my reply always returns 500 Server error. How can I report back model state errors without returning Json with whatever result. I would still like to return partial view that I can directly append to some HTML element. Edit I would also like to avoid returning error partial view. This would look like a success on the client. Having the client parse the result to see whether it's an actual success is prone to errors. Designers may change the partial view output and this alone would break the functionality. So I want to throw an exception, but with the correct error message returned to the ajax client.

  • Returning an array of culture formatted dates C# MVC3

    - by user1875797
    I'm new to programming and trying to do an exercise that formats a date to the Thai culture in a variety of formats this is what I have for my code so far: public String[] FormatAsSpecified(DateTime theDate, String theCulture, String[] formats) { String[] dateResults = new String[formats.Length]; CultureInfo culture = CultureInfo.GetCultureInfo(theCulture); for (int i = 0; i < formats.Length; i++) { String culture_formatted_date = theDate.ToString(formats[i], culture); dateResults[i] = culture_formatted_date; } return dateResults; } This is the test method that goes with it: [TestMethod] public void FormatAsSpecifiedReturnsDateLiteralsInSpecifiedFormatForAllStandardFormatStrings() { //Arrange var controller = new DateController(); var theDate = new DateTime(2014, 2, 14, 9, 15, 32, 376); String theCulture = "th-TH"; // Array of all supported standard date and time format specifiers. String[] formats = { "d", "D", "f", "F", "g", "G", "m", "o", "r", "s", "t", "T", "u", "U", "Y" }; //Corresponding date literals for the standard Thai regional settings String[] expectedResults = {"14/2/2557" , "14 ?????????? 2557" , "14 ?????????? 2557 9:15" , "14 ?????????? 2557 9:15:32" , "14/2/2557 9:15" , "14/2/2557 9:15:32" , "14 ??????????" , "2014-02-14T09:15:32.3760000" , "Fri, 14 Feb 2014 09:15:32 GMT" , "2014-02-14T09:15:32" , "9:15" , "9:15:32" , "2014-02-14 09:15:32Z" , "??????????? 14 ?????????? 2014 9:15:32" , "?????????? 2557"}; //Act String[] actualResults = new String[15]; for (int i = 0; i < formats.Length; i++) { actualResults[i] = controller.FormatAsSpecified(theDate, theCulture, formats[i]); } //Assert CollectionAssert.AreEqual(expectedResults, actualResults); } I get an error in the test method at 'controller.FormatAsSpecified(theDate, theCulture, formats[i]);' that says "Argument 3, cannot convert from 'string' to 'string[]'" What am I doing wrong?

  • How can I edit an entity in MVC4 with EF5 which has a unique constraint?

    - by Yoeri
    [HttpPost] public ActionResult Edit(Car car) { if (ModelState.IsValid) { db.Entry(car).State = EntityState.Modified; db.SaveChanges(); return RedirectToAction("Index"); } return View(car); } This is a controller method scaffolded by MCV 4 My "car" entity has a unique field: LicensePlate. I have custom validation on my Entity: Validation: public partial class Car { partial void ValidateObject(ref List<ValidationResult> validationResults) { using (var db = new GarageIncEntities()) { if (db.Cars.Any(c => c.LicensePlate.Equals(this.LicensePlate))) { validationResults.Add( new ValidationResult("This licenseplate already exists.", new string[]{"LicensePlate"})); } } } } should it be usefull, my car entity: public partial class Car:IValidatableObject { public int Id { get; set; } public string Color { get; set; } public int Weight { get; set; } public decimal Price { get; set; } public string LicensePlate { get; set; } public System.DateTime DateOfSale { get; set; } public int Type_Id { get; set; } public int Fuel_Id { get; set; } public virtual CarType Type { get; set; } public virtual Fuel Fuel { get; set; } public IEnumerable<ValidationResult> Validate(ValidationContext validationContext) { var result = new List<ValidationResult>(); ValidateObject(ref result); return result; } partial void ValidateObject(ref List<ValidationResult> validationResults); } QUESTION: Everytime I edit a car, it raises an error: Validation failed for one or more entities. See 'EntityValidationErrors' property for more details. The error is the one raised by my validation, saying it can't edit because there is already a car with that license plate. If anyone could point me in the right direction to fix this, that would be great! I searched but couldn't find anything, so even related posts are welcome!

  • FileContentResult and international characters

    - by suzi167
    Hello, I am using a fileContentResult to render a file to the browser. It works well except that it throws an exception when the fileName contains international characters. I remember reading somewhere that this feature does not support international characters but I am sure there mustbe a workaround or a best practice people follow in cases the application needs to upload files in countries other than US. Does anyone know of such a practice?Here is the ActionResult Method public ActionResult GetFile(byte[] value, string fileName) { string fileExtension = Path.GetExtension(fileName); string contentType = GetContentType(fileExtension); //gets the content Type return File(value, contentType, fileName); } THanks in advance Susan

  • Navigating back to "Home" from an area (MVC2)

    - by SlackerCoder
    I have a few areas in my application that are relatively independent (all navigated to from the master page). So, as of now, I am simply using the "default" MVC2 template (the one you get when you create a new MVC2 project). So the menu looks like this: HOME AREA1 AREA2 AREA3 AREA4 .... ABOUT Now, when I first load up the page, I am on the "HOME", and I can click on the ABOUT without issue. I can navigate to any of the areas as well, however, once I navigate to an area page, I cannot get back to my home or about pages (404 not found). When I navigate to them, and click on about, the address bar shows .../AreaX/Home/Home instead of Home/Home as I would expect. I expect that is has something to do with my routing, but Im not completely sure. I have added/changed nothing with the default routing (which is probably the issue!). Any thoughts?

  • With ASP .NET, how do I display a side submenu depending on what user picked from the main menu?

    - by Ole Media
    Hello, I come from PHP side, but I'm in need to develop a site using ASP .NET So far I manage to create a master page. Now I'm dealing with menus and submenus What I'm trying to do is, if the user picks "About Us" from the main menu, under the about us page I want to display a submenu with the options "who we are, what we do, contact us" If the user picks "Our Products" from the main menu, then under the products page I want to display a submenu with the options "product 1, product 2, product 3" Is this possible with only one master page? I read something about menu control but not sure that is what I need. So far I found how to display a sitemap, but not specific sections of a sitemap, if this is the way to do things. Any links, sample code, point of reference will be appreciated. Thanks

    I'm writing Validation attribute that sits on the class but inspects the properties of the class. I want it to set a validation message on each of the properties it finds to be invalid. How do I do this? This is what I have got so far: [AttributeUsage(AttributeTargets.Class, AllowMultiple = false, Inherited = true)] public class LinkedFieldValidationAttribute : ValidationAttribute { private readonly string[] _properiesToValidate; public LinkedFieldValidationAttribute(params string[] properiesToValidate) { _properiesToValidate = properiesToValidate; } public override bool IsValid(object value) { PropertyDescriptorCollection properties = TypeDescriptor.GetProperties(value); foreach (var propertyName in _properiesToValidate) { var propertyValue = properties.Find(propertyName, false).GetValue(value); //if value is invalid add message from base } //return validity } }

  • new operator in DllMain of MFC Extension Dll

    - by Picaro De Vosio
    Hi, Dll best practices document from Microsoft available Here recommends avoiding use of memory management function from the dynamic C Run-Time (CRT) within DllMain. But DllMain function of MFC Extension DLL is dynamically allocating the memory for CDynLinkLibrary in the code snippet available at MSDN "http://msdn.microsoft.com/en-us/library/1btd5ea3%28v=VS.80%29.aspx". Is it a violation of Dll Best Practices or ok to use in MFC extension DLL? thanks

  • Model-binding an object from the repository by several keys

    - by Anton
    Suppose the following route: {region}/{storehouse}/{controller}/{action} These two parameters region and storehouse altogether identify a single entity - a Storehouse. Thus, a bunch of controllers are being called in the context of some storehouse. And I'd like to write actions like this: public ActionResult SomeAction(Storehouse storehouse, ...) Here I can read your thoughts: "Write custom model binder, man". I do. However, the question is How to avoid magic strings within custom model binder? Here is my current code: public class StorehouseModelBinder : IModelBinder { readonly IStorehouseRepository repository; public StorehouseModelBinder(IStorehouseRepository repository) { this.repository = repository; } public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext) { var region = bindingContext.ValueProvider.GetValue("region").AttemptedValue; var storehouse = bindingContext.ValueProvider.GetValue("storehouse").AttemptedValue; return repository.GetByKey(region, storehouse); } } If there was a single key, bindingContext.ModelName could be used... Probably, there is another way to supply all the actions with a Storehouse object, i.e. declaring it as a property of the controller and populating it in the Controller.Initialize.

  • How to send html form data from one form to multiple database tables

    - by user1701556
    I am able to send html form data to database using hibernate. I am using mySQL, Hibernate, Java 1.6, Spriong 3.0. But I would like to send that same data to multiple tables in the database. My issue is that I want to use only one html form not multiple html form. I have these tables: name, address, email, login, phone_num. From this one html form I want data to go to different tables depending on what the data is. I want to do it using Hibernate so that I am not manually taking form data and inserting it in the database. Please let me know if this is possible.

  • ListBoxFor not populating with selected items

    - by user576838
    I've see this question asked a couple of other times, and I followed this after I tried things on my own with the MS music store demo to no avail, but I still can't get this to work. I've also noticed when I look at my MultiSelectList object in the viewmodel, it has the correct items in the selected items property, but if I expand the results view, it doesn't have any listboxitem with the selected value. What am I missing here? I feel like I'm taking crazy pills! Thanks in advance. model: public class Article { public int ArticleID { get; set; } public DateTime? DatePurchased { get; set; } public DateTime? LastWorn { get; set; } public string ThumbnailImg { get; set; } public string LargeImg { get; set; } public virtual List<Outfit> Outfits { get; set; } public virtual List<Tag> Tags { get; set; } } viewmodel: public class ArticleViewModel { public int ArticleID { get; set; } public List<Tag> Tags { get; set; } public MultiSelectList mslTags { get; set; } public virtual Article Article { get; set; } public ArticleViewModel(int ArticleID) { using (ctContext db = new ctContext()) { this.Article = db.Articles.Find(ArticleID); this.Tags = db.Tags.ToList(); this.mslTags = new MultiSelectList(this.Tags, "TagID", "Name", this.Article.Tags); } } } controller: public ActionResult Index() { ArticleIndexViewModel vm = new ArticleIndexViewModel(db); return View(vm); } view: @model ClosetTracker.ArticleViewModel @using (Html.BeginForm()) { <img id="bigImg" src="@Model.Article.ThumbnailImg" alt="img" /> @Html.HiddenFor(m => m.ArticleID); @Html.LabelFor(m => m.Article.Tags) @* @Html.ListBoxFor(m => m.Article.Tags, Model.Tags.Select(t => new SelectListItem { Text = t.Name, Value = t.TagID.ToString() }), new { Multiple = "multiple" }) *@ @Html.ListBoxFor(m => m.Article.Tags, Model.mslTags); @Html.LabelFor(m => m.Article.LastWorn) @Html.TextBoxFor(m => m.Article.LastWorn, new { @class = "datepicker" }) @Html.LabelFor(m => m.Article.DatePurchased) @Html.TextBoxFor(m => m.Article.DatePurchased, new { @class = "datepicker" }) <p> <input type="submit" value="Save" /> </p> } EDITED Ok, I changed around the constructor of the MultiSelectList to have a list of TagID in the selected value arg instead of a list of Tag objects. This shows the correct tags as selected in the results view when I watch the mslTags object in debug mode. However, it still isn't rendering correctly to the page. public class ArticleViewModel { public int ArticleID { get; set; } public List<Tag> Tags { get; set; } public MultiSelectList mslTags { get; set; } public virtual Article Article { get; set; } public ArticleViewModel(int ArticleID) { using (ctContext db = new ctContext()) { this.Article = db.Articles.Find(ArticleID); this.Tags = db.Tags.ToList(); this.mslTags = new MultiSelectList(this.Tags, "TagID", "Name", this.Article.Tags.Select(t => t.TagID).ToList()); } } }
