• Problem running ASP.NET MVC 2 website on IIS7

  - by Charlie

  I'm trying to deploy my ASP.NET MVC 2 website from VS2010 beta 2 to IIS7. The publish works fine but none of the routes work, so when I go to the URL http://localhost/myapp/Home/Index I get the error: HTTP Error 404.0 - Not Found The resource you are looking for has been removed, had its name changed, or is temporarily unavailable. I'm deploying to a virtual directory which is using an app pool configured for the .NET 4 framework with managed pipeline mode set to integrated. Also, if I go Basic Settings-Test Connection, both tests pass. From what I understand, it should just work? I don't have any problems deploying Nerd Dinner from VS2008, that works fine.

• DWR and Jquery into spring MVC 2.5

  - by Mark Estrada

  Hi, From my shallow reading, Spring MVC does not support jquery directly. It does enable integration with DWR framework. From my understanding of DWR, it is an ajax framework that allows you to call javas methods from javascript. Can I use both in my application? With Jquery handling most of the javascript code and client side interaction and DWR making the ajax calls? I am leaning towards learning jquery but there is no out of the box support for it in spring 2.5.

• Is there a certain IIS configuration required to allow a functioning .Net 4.0 ASP.Net MVC 2 Azure ap

  - by erg39

  I just installed the Azure 1.2 tools update and would like to get to work on an Azure project running locally using ASP.Net MVC and .Net 4, but I cannot get MVC pages to load. If I just create a new Azure project in VS 2010, add a ASP.Net MVC web role, and run the application, pages never load. It appears that routing is somehow at fault as controller actions never get called, but if I add other pages to the project (like .htm or .aspx) they will load in the browser. It all works fine with a new project using .Net 3.5, MVC 2 project in the Azure development environment; it all works fine with .Net 4.0 MVC 2 project that is not running in Azure; only the combination does not work. Environment is Win 7 x64 (IIS 7.5), VS 2010, Azure tools 1.2 Is there some magic IIS setting I need to change or something? Any ideas?

• ASP.NET MVC authorization & permission to use model classes

  - by Tomek

  Hi, This is my first post here, so hello :) Okey, let's get to the point... I am writing my first app in ASP.NET MVC Framework and i have a problem with checking privileges to use instances of model classes (read, edit). Sample code looks like this: // Controller action [CustomAuthorize(Roles="Editor, Admin")] public ActionResult Stats(int id) { User user = userRepository.GetUser(id); if (user == null || !user.Activated || user.Removed) return View("NotFound"); else if (!user.IsCurrentSessionUserOwned) return View("NotAuthorized"); return View(user); } So far authorize attribute protects only controller actions, so my question is: how to make (custom) authorize attribute to check not only user role, usernames but also did i.e. resources instantiated in action methods (above: User class, but there are other ORM objects like News, Photos etc.) All of these object to check have their unique ID's, so user have own ID, News have their ID and UserID field referecned to Users table (i mean these objects are LINQ2SQL classes). How should i resolve that problem?

• Spring - MVC - Sanitize URL before redisplaying to the user

  - by Raghav

  In my application , a HTTP GET request URL to the application with script tag is getting redisplayed as it is although it fails the authorization. Example: http://www.example.com/welcome<script>alert("hi")</script> The issue is sanitizing external input entered directly into address bar by modifying existing GET URL. Spring redisplays the submitted URL as it is. Though the script does not get executed in the browser(FF), is there anyway to strip the URL of these values before displaying it back to the user Reference: Spring MVC application filtering HTML in URL - Is this a security issue?

• logic of button to be disabled or not in mvc

  - by rod

  Hi All, Here's an excerpt from a book I'm reading about application design with MVC: Ideally, the view is so simple and logic-free as to need virtually no testing. Users (and developers before users) can reasonably test the view by simply looking at the pixels on the screen. Anything else beyond pure graphical rendering should ideally be taken out of the view and placed in the controller and model. This includes, for example, the logic that determines whether a certain button should be enabled or grayed out at some point. what does the bold statement mean to you? what would this look like? thanks, rod.

• How to catch HttpAntiForgeryException in ASP.NET MVC

  - by megalonychidae

  I'm using the AntiForgeryToken in my ASP.NET MVC forms. If I deactivate cookies in my browser and send the from, I'd get following error message: A required anti-forgery token was not supplied or was invalid. How can I prevent this message from showing? I would prefer redirecting the user to another page. I've activated customErrors and included this HandleError in my controller: [HandleError(ExceptionType=typeof(HttpAntiForgeryException), View="Index")] public class MyController : Controller { ... } The HandleError is ignored. Has anyone got a solution?

• ASP.NET MVC Populating a DropDownList with a value from the view

  - by lomaxx

  In my controller I have this: ViewData["maskList"] = new SelectList(equipmentRepository.GetMasks(), "Id", "DisplayName"); and then I bind it to my view using <div each="var nfa in mfa.NasalFittingAssessment"> ${Html.DropDownList("NasalMaskTypeId", ViewData["maskList"] as IEnumerable<System.Web.Mvc.SelectListItem>, new { class = "ddl" })} </div> Note that I'm using the spark view engine so this DropDownList is getting rendered to the page via a loop. This means that the selected value of the dropdown list will change on each iteration of the loop. What I can't work out is how to pass in the value I want to set the DropDownList to based on the value that is currently being rendered to the screen.

• In MVC view page javascript file url not resolving

  - by Ashwani K

  Hello All: I have one MVC view page in which I show different links and I am using ThickBox to show a different page when ever one of these links is clicked. In these pages, I am using jQuery functions to do some changes, but I am not able to resolve the jquery file path on the view pages. I need to give absolute path something like "http://test.com/js/jquery.js". But is there any way to make it relative? I also tried getting the host url and using <%=% and <%# % but none is working. Any help? Thanks Ashwani

• Rails flash hash violation of MVC?

  - by user94154

  I know Rails' flash hash is nothing new, but I keep running into the same problem with it. Controllers should be for business logic and db queries, not formatting strings for display to the user. But the flash hash is always set in the controller. This means that I need to hack and work around Rails to use Helpers that I made to format strings for the flash hash. Is this just a pragmatic compromise to MVC or am I missing something here? How do you deal with this problem? Or do you not even see it as one?

• App with MVC Virtual application shared AuthCookie.

  - by Razcer

  I have a 3.5 ASP.Net WebForm parent application. The parent uses forms authentication. I have a MVC child virtual application, I would like to make it so the user logs in to the parent application, user then navigates to the virtual application by pressing a link on the parent. However every time I do this it goes to the login screen for the virtual application. Is there a web setting I should double check in Parent? Or Child? Is there an IIS setting that I should check? Should I be using a virtual directory instead of virtual application? I want the child to be able to access the Session[] from the parent. I would like the child app to use the same authCookie as the parent app.

• Null file when uploading via MVC

  - by Josh

  I have the following form on an .NET MVC View: <form method="post" enctype="multipart/form-data" action="/Video/UploadDocument"> <input type="file" id="document1" name="document1"/> <input type="submit" value="Save"/> </form> And the controller has the following signature that gets called: public ActionResult UploadDocument(HttpPostedFileBase file) { return View(); } When I break inside the UploadDocument method, the parameter 'file' is null. I've selected a valid document on my desktop and know it contains text. What am I missing to get this file upload working?

• ReturnUrl = Default.aspx for MVC?

  - by Cynthia

  I'm trying to secure my entire MVC site, so before the Home controller, I added an [Authorize] attribute. Now if you run it from Visual Studio or navigate using the root URL (e.g. http://localhost:2897) it does redirect to the login page, as expected. However the URL in the address bar after redirection looks like this: http://localhost:2897/Account/LogOn?ReturnUrl=%2fdefault.aspx%3f I haven't tested this out, seeing as I have not implemented my authentication code. However, this looks like a big problem to me, since I do not have a default.aspx in my project! My authentication tag in the web.config looks like this: <authentication mode="Forms"> <forms loginUrl="~/Account/LogOn" defaultUrl="~/Home/Index" timeout="2880"/> </authentication> Why doesn't it pick up this route as the default ReturnUrl instead of default.aspx?

• ASP.NET MVC: What's the difference in concept between Service and Repository

  - by Richard77

  Hello, The question I'm asking is kind of subjective. I've seen twice, while exercising with real projects such as StoreFront, both Repository and Services. Sometimes they can just be folders or projects attached to the solution. But they contain classes and interfaces. So, I'd like to know what goes to the repository and what goes to the services. So far, I was familiar with repositories (we put methods and properties in the repository to reduce the complexity in the controller). How about the services? So, ASP.NET MVC: What's the difference in concept between Service and Repository? (Maybe none) My question is Kind of subjective, but I'd like to make sure that I'm not missing anything. Thanks for helping

• Redirect away from HTTPS with ASP.NET MVC App

  - by Amadiere

  I'm using ASP.NET MVC 2 and have a login page that is secured via HTTPS. To ensure that the user always accesses those pages via SSL, I've added the attribute [RequiresHttps] to the controller. This does the job perfectly. When they have successfully logged in, I'd like to redirect them back to HTTP version. However, there isn't a [RequiresHttp] attribute and I'm struggling to get my head around how I might achieve this. The added (potential) complication is that the website when in production is hosted at the route of the domain, but for development and testing purposes it is within a sub directory / virtual directory / application. Am I over-thinking this and is there an easy solution staring me in the face? Or is it a little more complex?

• ASP.NET MVC UpdateModel - fields vs properties??

  - by mrjoltcola

  I refactored some common properties into a base class and immediately my model updates started failing. UpdateModel() and TryUpdateModel() did not seem to update inherited public properties. I cannot find detailed info on MSDN nor Google as to the rules or semantics of these methods. The docs are terse (http://msdn.microsoft.com/en-us/library/dd470933.aspx), simply stating: Updates the specified model instance using values from the controller's current value provider. SOLVED: MVC.NET does indeed handle inherited properties just fine. This turned out to have nothing to do with inheritance. My base class was implemented with public fields, not properties. Switching them to formal properties (adding {get; set; }) was all I needed. This has bitten me before, I keep wanting to use simple, public fields. I would argue that fields and properties are syntactically identical, and could be argued to be semantically equivalent, for the user of the class.

• mvc 2.0 updatemodel and my ID Column

  - by femi

  Hello, I have created a create view within my MVC 2.0 Application and by default it included a field for the integer ID Column. This is definitely a field i do not need. If i remove the field and use updatemodel when trying to create the object in code, will something break because it doesnt see my ID column data being passed in, even though it is auto increment? Also, i noticed that in the NerdDinner example, updatemodel was used and after that the repository.save method was called. I thought that updatemodel would save the object to the database..why then call the .save method afterwards? Or have i missed something? Any help with this would be appreciated. Cheers

• ASP.NET MVC Session usage

  - by Ben

  Currently I am using ViewData or TempData for object persistance in my ASP.NET MVC application. However in a few cases where I am storing objects into ViewData through my base controller class, I am hitting the database on every request (when ViewData["whatever"] == null). It would be good to persist these into something with a longer lifespan, namely session. Similarly in an order processing pipeline, I don't want things like Order to be saved to the database on creation. I would rather populate the object in memory and then when the order gets to a certain state, save it. So it would seem that session is the best place for this? Or would you recommend that in the case of order, to retrieve the order from the database on each request, rather than using session? Thoughts, suggestions appreciated. Thanks Ben

• How to version MVC JavaScript includes

  - by Ed

  I'm working with someone else's code, so I don't know the whole picture, and I don't even know MVC that well, but here's the problem... In Site.Master there's a <%= Html.IncludeJs("ProductPartial")%> which produces this line in the final mark-up <script type="text/javascript" src="/Scripts/release/ProductPartial.js"></script> I made some changes in the JS file, but the old one is obviously cached by the browser, so the changes won't show up until the user refreshes. The usual workaround is to add a version tag at the end of the script source path, but I'm not sure how to do that in this case. Any suggestions?

• Dynamic data validation in ASP.NET MVC

  - by user252160

  I've recently read about the model validation capabilities of ASP.NET MVC which are all very cool until a certain point. What happens if the application doesn't know the data that it works with because it is all stored in DB and built together at runtime. Just like in Drupal, I'd like to be able to define custom types at runtime, and assign runtime validation rules as well. Obviously, the idea of assigning attributes to well established models is now gone. What else could be done ? I am thinking in terms of rules being stored as JSON objects in the DB fields or something like that.

• Read OAuth2.0 Signed_Request Facebook Registration C# MVC

  - by Josh

  My question is very similar this but I guess I need to take it one step further. Facebook says "The data is passed to your application as a signed request. The signed_request parameter is a simple way to make sure that the data you're receiving is the actual data sent by Facebook." After a user has logged into my asp c# MVC site and clicked "Register", the redirect-url is http://site/account/register. At that point (the post to the account/register control), I would like to gather the user's information using the signed request so that I can register them with my site locally. I cannot figure out how to access the data facebook makes available. $data = json_decode(base64_url_decode($payload), true); What is the equivalent in C#? What type of variable/data is facebook passing in the post? And how do I access "$payload"?

• What is an example of MVC in PHP?

  - by waiwai933

  I'm trying to understand the MVC pattern. Here's what I think MV is: Model: <?php if($a == 2){ $variable = 'two'; } else{ $variable = 'not two'; } $this->output->addContent($variable); $this->output->displayContent(); ?> View: <?php class output{ private $content; public function addContent($var){ $this->content = 'The variable is '.$var; } public function displayContent(){ include 'header.php'; echo $content; include 'footer.php'; } } ?> Is this right? If so, what is the controller?
