• Controller name convention in ASP.NET MVC

  - by jesusbolivar

  Is there a way to change the naming convention for controllers in ASP.NET MVC? What I want is to name my controllers InicioControlador instead of InicioController, or better yet, use a prefix instead of a suffix, and have ControladorInicio as my controller name. From what I have read so far, I think I have to implement my own Controller Factory. I would be very grateful if any of you could point me in the right direction.

• How can i Execute a Controller's ActionMethod programatically?

  - by Pure.Krome

  Hi folks, I'm trying to execute a controller's Action Method programatically and I'm not sure how. Scenario: When my ControllerFactory fails to find the controller, I wish it to manually execute a single action method which i have on a simple, custom controller. I don't want to rely on using any route data to determine the controller/method .. because that route might not have been wired up. Eg. // NOTE: Error handling removed from this example. public class MyControllerFactory : DefaultControllerFactory { protected override IController GetControllerInstance(Type controllerType) { IController result = null; // Try and load the controller, based on the controllerType argument. // ... snip // Did we retrieve a controller? if (controller == null) { result = new MyCustomController(); ((MyCustomController)result).Execute404NotFound(); // <-- HERE! } return result; } } .. and that method is .. public static void Execute404NotFound(this Controller controller) { result = new 404NotFound(); // Setup any ViewData.Model stuff. result.ExecuteResult(controller.ControllerContext); // <-- RUNTIME // ERROR's HERE } Now, when I run the controller factory fails to find a controller, i then manually create my own basic controller. I then call the extension method 'Execute404NotFound' on this controller instance. That's fine .. until it runs the ExecuteResult(..) method. Why? the controller has no ControllerContext data. As such, the ExecuteResult crashes because it requires some ControllerContext. So - can someone out there help me? see what I'm doing wrong. Remember - i'm trying to get my controller factory to manually / programmatically call a method on a controller which of course would return an ActionResult. Please help!

• Magento config XML for adding a controller action to a core admin controller

  - by N. B.

  I'm trying to add a custom action to a core controller by extending it in a local module. Below I have the class definition which resides in magento1_3_2_2/app/code/local/MyCompany/MyModule/controllers/Catalog/ProductController.php class MyCompany_MyModule_Catalog_ProductController extends Mage_Adminhtml_Catalog_ProductController { public function massAttributeSetAction(){ ... } } Here is my config file at magento1_3_2_2/app/code/local/MyCompany/MyModule/etc/config.xml: ... <global> <rewrite> <mycompany_mymodule_catalog_product> <from><![CDATA[#^/catalog_product/massAttributeSet/#]]></from> <to>/mymodule/catalog_product/massAttributeSet/</to> </mycompany_mymodule_catalog_product> </rewrite> <admin> <routers> <MyCompany_MyModule> <use>admin</use> <args> <module>MyCompany_MyModule</module> <frontName>MyModule</frontName> </args> </MyCompany_MyModule> </routers> </admin> </global> ... However, https://example.com/index.php/admin/catalog_product/massAttributeSet/ simply yields a admin 404 page. I know that the module is active - other code is executing fine. I feel it's simply a problem with my xml syntax. Am I going about this the write way? I'm hesitant because I'm not actually rewriting a controller method... I'm adding one entirely. However it does make sense in that, the original admin url won't respond to that action name and it will need to be redirected. I'm using Magento 1.3.2.2 Thanks for any guidance.

• How much time do I have to remove a domain controller that was lost using metadata cleanup?

  - by dasko

  I am wondering how long after a Domain Controller has been permanently lost, from the domain due to it dying from hardware perspective, do I have before I have to clean up references of it using meta data cleanup? Planning on doing it soon but not sure if there is anything I should be concerned about. This dead or lost domain controller had no roles other than being a Domain Controller and having integrated Active Directory DNS. As well it held NO FSMO roles, it was just an older replication Domain Controller.

• 3 Simple Steps to Achieving a Front Page Search Listing on Google

  It's a fact that most website owners struggle to get traffic to their sites. Unless you are very fortunate or have invested a lot of time and money in SEO then getting a front page ranking on Google for a highly searched keyword phrase is normally just a pipe dream. After all, there are only 10 front page spots to be had and competition to secure one is incredibly high - as are the rewards.

• Changing frontend cache

  - by Utsav

  Our architecture consists of a front-end cache that most read only users obtain their data from directly. The front-end cache sits in front of a farm of webservers that serve pages written in PHP. We need to be able to detect certain conditions at the front-end cache level and pass those values through to the back-end via HTTP headers. For example we would like to manually tag the carrier network based on the IP address. So, for incoming traffic if the user is say coming from an IP address in the range of "41.202.192.0"/19 we would tag them as being a Orange Cameroon user by setting the appropriate HTTP request header, e.g., X-Carrier = "Orange Cameroon". Based on the setting of this header we would like to vary the cache and serve a different banner to the end user. How would you go about doing this? Keep in mind that we don't want to pollute the cache and we also don't want to create too many small cache segments. Assumptions: You can assume that the X-Carrier has already been detected in our cache. So, for the purposes of your test you can just set this value manually in your example script.

• Sd card bigger than 2gb is not recognized in ubuntu 12.04

  - by dex1

  When I insert a card up to 2gb it is immediately seen by the system but if try it with bigger one it's not seen. I presume the issue is not due to the card reader itself as it reads all cards under windows 7 but due to linux driver. I could see some people having similar issues but no solution.

• Where do I read more about building an architecture like Google has? [on hold]

  - by user107148

  I want to develop a program that watches and traverses a rather big network for data. This data should then be available to search through with my program, maybe through a web interface or something. My intuitive thought at the moment is to build an architecture kind of like the one Google has. One "front-end" (the Google Search page) which is essentially a regular web application and one "back-end" (which in Google's case traverses the web). Now for the hard part: If I decide to make such a system, how should communication be done between these parts? One idea I had is to use some kind of database that both the back-end and front-end can access, but then comes the issues of concurrent writes and reads. Another issue with just using a database to communicate is that it makes it hard to "notify" the other part when something changes. Let's say that I want the "front-end" part to push changes to the UI when a change is noticed in the back-end. Then the back-end would have to have some way of notifying the front-end of this.

• Creating predefinied camera views - How do I move the camera to make sense while using Controller?

  - by Deukalion

  I'm trying to understand 3D but the one thing I can't seem to understand is the Camera. Right now I'm rendering four 3D Cubes with textures and I set the Project Matrix: public BasicCamera3D(float fieldOfView, float aspectRatio, float clipStart, float clipEnd, Vector3 cameraPosition, Vector3 cameraLookAt) { projection_fieldOfView = MathHelper.ToRadians(fieldOfView); projection_aspectRatio = aspectRatio; projection_clipstart = clipStart; projection_clipend = clipEnd; matrix_projection = Matrix.CreatePerspectiveFieldOfView(projection_fieldOfView, aspectRatio, clipStart, clipEnd); view_cameraposition = cameraPosition; view_cameralookat = cameraLookAt; matrix_view = Matrix.CreateLookAt(cameraPosition, cameraLookAt, Vector3.Up); } BasicCamera3D gameCamera = new BasicCamera3D(45f, GraphicsDevice.Viewport.AspectRatio, 1.0f, 1000f, new Vector3(0, 0, 8), new Vector3(0, 0, 0)); This creates a sort of "Top-Down" camera, with 8 (still don't get the unit type here - it's not pixels I guess?) But, if I try to position the camera at the side to make "Side-View" or "Reverse Side View" camera, the camera is rotating to much until it's turned around it a couple of times. I render the boxes at: new Vector3(-1, 0, 0) new Vector3(0, 0, 0) new Vector3(1, 0, 0) new Vector3(1, 0, 1) and with the Top-Down camera it shows good, but I don't get how I can make the camera show the side or 45 degrees from top (Like 3rd person action games) because the logic doesn't make sense. Also, since every object you render needs a new BasicEffect with a new projection/view/world - can you still use the "same" camera always so you don't have to create a new View/Matrix and such for each object. It's seems weird. If someone could help me get the camera to navigate around my objects "naturally" so I can be able to set a few predtermined views to choose from it would be really helpful. Are there some sort of algorithm to calculate the view for this and perhaps not simply one value? Examples: Top-Down-View: I have an object at 0, 0, 0 when I turn the right stick on the Xbox 360 Controller it should rotate around that object kind of, not flip and turn upside down, disappear and then magically appear as a tiny dot somewhere I have no clue where it is like it feels like it does now. Side-View: I have an object at 0, 0, 0 when I rotate to sides or up and down, the camera should be able to show a little more of the periphery to each side (depending on which you look at), and the same while moving up or down.

• Simulate analogue steering wheel input from third party software like xPadder

  - by David Jensen

  So. I currently have a steering wheel connected to my htpc. Since it wont work / get recognized by all games i play. I use xpadder to play for example Grid 3. As far as i have understood, it simply presses the associated arrow key when i turn the wheel. What i would like, is a software to simulate more and more frequent key presses of the arrow keys the more i turn the wheel. Example: Tilting a little - 100 presses / second Tilting more - 200 presses / second Tilting max - Hold down key Because what i currently do with the wheel is constantly shaking it a bit right, when i just want to turn a little bit right and so on.

• Push/Present Modal View Controller

  - by Yakattak

  I have a table in my view controller (let's call it TVC1). I have rows in TVC1 that are used so the user can input some more data in addition to the data on TVC1. So, when someone taps a specific row in TVC1, it will show another view controller (let's call it TVC2). However, when TVC2 is shown, all of the data in TVC1 is cleared. How can I save the data in TVC1? Should I do it through the app delegate? DescriptionInputViewController *descriptionController = [[DescriptionInputViewController alloc] initWithNibName:@"DescriptionInputView" bundle:nil]; [self presentModalViewController:navController animated:YES]; [self.navigationController pushViewController:descriptionController animated:YES]; [descriptionController release];

• Codeigniter: Retrieving a variable from Model to use in a Controller

  - by Craig Ward

  Hi, I bet this is easy but been trying for a while and can't seem to get it to work. Basically I am setting up pagination and in the model below I want to pass $total_rows to my controller so I can add it to the config like so '$config['total_rows'] = $total_rows;'. function get_timeline_filter($per_page, $offset, $source) { $this->db->where('source', $source); $this->db->order_by("date", "desc"); $q = $this->db->get('timeline', $per_page, $offset); $total_rows = $this->db->count_all_results(); if($q->num_rows() >0) { foreach ($q->result() as $row) { $data[] = $row; } return $data; } } I understand how to pass things form the Controller to the model using $this->example_model->example($something); but not sure how to get a variable from the model?

• My helper methods in controller

  My app should render html, to answer when a user clicks ajax-link.

  Hi, i need to read out all available actions from any controller in my web-app. The reason for this is an authorization system where i need to give users a list of allowed actions. E.g.: User xyz has the authorization for executing the actions show, list, search. User admin has the authorization for executing the actions edit, delete etc. I need to read out all actions from a controller. Does anyone has an idea? Thx for any help! kenan

• ASP.NET MVC pass information from controller to view WITHOUT ViewData, ViewModel, or Session

  - by josh

  I have a unique scenario where I want a base controller to grab some data and store it in a list. The list should be accessible from my views just as ViewData is. I will be using this list on every page and would like a cleaner solution than just shoving it in the ViewDataDictionary. After attempting to come up with a solution, I thought I would create a custom ViewPage with a property to hold my list. My custom ViewPage would inherit from System.Web.MVC.ViewPage. However, I do not know where MVC passes the viewdata from the controller off to the view. More importantly, how do I get it to pass my list down to the view? Thanks for the help.

• Returning Json object from controller action to jQuery

  - by PsychoCoder

  I'm attempting to get this working properly (2 days now). I'm working on a log in where I'm calling the controller action from jQuery, passing it a JSON object (utilizing json2.js) and returning a Json object from the controller. I'm able to call the action fine, but instead of being able to put the response where I want it it just opens a new window with this printed on the screen: {"Message":"Invalid username/password combination"} And the URL looks like http://localhost:13719/Account/LogOn so instead of calling the action and not reloading the page it's taking the user to the controller, which isn't good. So now for some code, first the controller code [HttpPost] public ActionResult LogOn(LogOnModel model, string returnUrl = "") { if (ModelState.IsValid) { var login = ObjectFactory.GetInstance<IRepository<PhotographerLogin>>(); var user = login.FindOne(x => x.Login == model.Username && x.Pwd == model.Password); if (user == null) return Json(new FailedLoginViewModel { Message = "Invalid username/password combination" }); else { if (!string.IsNullOrEmpty(returnUrl)) return Redirect(returnUrl); else return RedirectToAction("Index", "Home"); } } return RedirectToAction("Index", "Home"); } And the jQuery code $("#signin_submit").click(function () { var login = getLogin(); $.ajax({ type: "POST", url: "../Account/LogOn", data: JSON.stringify(login), dataType: 'json', contentType: 'application/json; charset=utf-8', error: function (xhr) { $("#message").text(xhr.statusText); }, success: function (result) { } }); }); function getLogin() { var un = $("#username").val(); var pwd = $("#password").val(); var rememberMe = $("#rememberme").val(); return (un == "") ? null : { Username: un, Password: pwd, RememberMe: rememberMe }; } In case you need to see the actual login form here that is as well <fieldset id="signin_menu"> <div> <span id="message"></span> </div> <% Html.EnableClientValidation(); %> <% using (Html.BeginForm("LogOn", "Account", FormMethod.Post, new { @id = "signin" })) {%> <% ViewContext.FormContext.ValidationSummaryId = "valLogOnContainer"; %> <%= Html.LabelFor(m => m.Username) %> <%= Html.TextBoxFor(m => m.Username, new { @class = "inputbox", @tabindex = "4", @id = "username" })%><%= Html.ValidationMessageFor(m => m.Username, "*")%> <p> <%= Html.LabelFor(m=>m.Password) %> <%= Html.PasswordFor(m => m.Password, new { @class = "inputbox", @tabindex = "5", @id = "password" })%><%= Html.ValidationMessageFor(m => m.Password, "*")%> </p> <p class="remember"> <input id="signin_submit" value="Sign in" tabindex="6" type="submit"/> <%= Html.CheckBoxFor(m => m.RememberMe, new { @class = "inputbox", @tabindex = "7", @id = "rememberme" })%> <%= Html.LabelFor(m => m.RememberMe) %> <p class="forgot"> <a href="#" id="forgot_password_link" title="Click here to reset your password.">Forgot your password?</a> </p> <p class="forgot-username"> <a href="#" id="forgot_username_link" title="Fogot your login name? We can help with that">Forgot your username?</a> </p> </p> <%= Html.ValidationSummaryJQuery("Please fix the following errors.", new Dictionary<string, object> { { "id", "valLogOnContainer" } })%> <% } %> </fieldset> The login form is loaded on the main page with <% Html.RenderPartial("LogonControl");%> Not sure if that has any bearing on this or not but thought I'd mention it. EDIT: The login form is loaded similar to the Twitter login, click a link and the form loads with the help of jQuery & CSS

• Passing Data from Usercontrol to controller

  - by nitinkhanna

  Hi, I am new to MVC, and trying something and got stuck somewhere in between. I have a user control there I have three textbox html type(ID, Lastname, firstname) and a submit buttom. I set the button like <input type="button" value="Search" onclick="location.href='<%= Url.Action("action", "controller") %>'" /> I have called this usercontrol on some view through <%= Html.Partial("ucName") %> Now on pressing that button(on user control) I need to pass the data from these textboxes to controller again to some specific action(Http Post action). By using this data I want to do some database interaction and storing the result in a dataset and pass this data set to same view again to show up in some Grid. I know the first part in conventional Asp.net can be done by raising the event through delegate but don't know how to do that in MVC.

• Unit testing a controller in ASP.NET MVC 3

  - by Abdullah Al- Mansur

  public Double Invert(Double? id) { return (Double)(id / id); } I have done this for this test but fails please can anyone help with this cos just started with unit testing /* HINT: Remember that you are passing Invert an *integer* so * the value of 1 / input is calculated using integer arithmetic. * */ //Arrange var controller = new UrlParameterController(); int input = 7; Double expected = 0.143d; Double marginOfError = 0.001d; //Act var result = controller.Invert(input); //Assert Assert.AreEqual(expected, result, marginOfError); /* NOTE This time we use a different Assert.AreEqual() method, which * checks whether or not two Double values are within a specified * distance of one another. This is a good way to deal with rounding * errors from floating point arithmetic. Without the marginOfError * parameter the assertion fails. * */

• CakePHP Auth how to allow specific controller and actions

  I have a "Posts" and a "Users" controller. I use the Auth Component and I want that all users can visit "Post.index" but only logged in users can visit "User.index". In my app_controller.php I have this $this->Auth->allow('signup', 'confirm', 'index'); but with that all users can visit post.index and user.index. How can I specify a Controller in the allow-method? This didn't work for me: $this->Auth->allow('signup', 'confirm', 'Post.index');

• JSF 2 Content Controller (pull in content based on URI)

  - by gerges

  Hey All, I'm new to JSF and am trying to make a content controller. Basically whenever someone makes a request to www.myapp.com/external/** I'd like to forward to a controller that pulls external content into a page template and spits it out to the user. I was able to achive this pretty easily in Spring 3, but I'm a little confused on where to start with JSF. I feel like I'd need to create a custom servlet to handle /external/**? But what would the class of this servlet be? What would it consist of? Any help is appreciated!
