  • Html.ActionLink in a button

    - by Pomster
    I Am trying to connect to a method in my controller, with a button. I can connect though this link: @Html.ActionLink("Print", "Print", new { id = Model.SalesContractId}) But i Don't want a link, i want my button on my dialog to do it. I have tried the following: $('#btnDialogPrint').click(function () { location.href = '<%= Url.Action("Print", "Print", new { id = Model.SalesContractId}) %>'; }); But it just redirect me to a page that say bad request. namespace Contract.Controllers { public class ContractController : Controller { CompassEntities db = new CompassEntities(); public ActionResult Print(int id) { return View(""); // This can be removed and Print code may be added } Don't worry about the code inside i will get to that once i get inside this method. Could i maybe attach a link here? <input type="button" value="Print" id="btnDialogPrint" />

  • iPhone: Waiting until selectrow animation finishes before pushing viewcontroller?

    - by Mike
    My code looks like this: NSIndexPath *ip = [NSIndexPath indexPathForRow:15 inSection:0]; [[self tableView] selectRowAtIndexPath:ip animated:YES scrollPosition:UITableViewScrollPositionMiddle]; // Pause needed here until animation finishes [[self navigationController] pushViewController:secondView animated:YES]; Right now it animates the scroll/selection of the row and pushes the view controller at the same time. What I would like it to do is wait until it finishes the scroll/selection and then push the view controller. Is there any possible way of doing this? Thanks

  • Are these REST HTTP response codes right, and what about the Content-Type?

    - by talentedmrjones
    I'm writing a controller helper that sets the proper response headers for my REST controller action. It's pasted below and should be simplified enough for those who aren't familiar with Zend Framework to understand what I'm doing. My question is: Are these codes correct for their respective responses, and in the case of "access denied" do I use a 401 or 403? Also, in case of responding with an error, I understand I should be placing a message in the response body, but should I set the "Content-Type" to "text/plain"? <?php class App_Controller_Helper_RestResponse extends Zend_Controller_Action_Helper_Abstract { public function denied() { // 403 or 401? } public function notFound() { // 404 } public function created() { // 201 } public function deleted() { // 204 } public function redirect() { // 301 // new url } public function malformed() { // 400 } public function gone() { // 410 } }

  • Searching in Rails 3

    - by cbarton
    Here is the situation: I have the need to search for specifics or generals, much like expedia.com or your local library catalog search. In that there are fields that may or may not be filled out based on the individual need. It acts much like an "advanced search page". I have all of that code done for the models/controller and such and have it setup with a Searches controller along with matching model and views. The question that I have is there a way to cut down the amount of parameters posted to GET so that the url isn't search?search[:a]=""+search[:b]=""+search[:c]="x"... plus the unicode checkmark. I only want the filled out fields to be shown in the response link especially minus the checkmark. cbarton

  • IIS7.5 and MVC 2 : Implementing HTTP(S) security

    - by Program.X
    This is my first ASP.NET MVC application, and my first on an IIS 7.x installation whereby I have to do anything over and above the standard. I need to enforce Windows authentication on the /Index and /feeds/xxx.svc pages/services. In ASP.NET Web Forms, I would apply the Windows permissions on the files and remove Anonymous authentication in IIS 6. This needs to work over HTTP/S, but don't worry about that, that's in hand. What happens in MVC/IIS 7? I have tried modifying the permissions on the /Index.aspx view, which seems to block access. It asks me for a username/password, but does not grant access when I enter a valid username/password. Pressing Escape gives me an exception "*Access to the path 'E:\dev\xxx\xxx.ConsultantRegistration.Web.Admin\Views\ConsultantRegistration\index.aspx' is denied. *", which does get sent as a 401. So although the username/password does exist on the Index.aspx view, I can't use those credentials to access said view. I have in my web.config: What am I missing?

  • Detect that the onscreen keyboard has been displayed on Windows Phone 7

    - by David_001
    Simple question: How do I detect that the onscreen keyboard has been displayed on windows mobile 7? Is there an event I can add a listener to? It takes up about half the screen and I want to scroll the view up when it gets displayed... EDIT: A comment below indicates more clearly what I'm trying to do: I have a textbox input, and as the user types into it an autocomplete dropdown appears below it (like google suggest). By default, the active control (the textbox) scrolls into view when focussed, and the onscreen keyboard is directly below it. The onscreen keyboard appears in front of my autocomplete dropdown - what I want to do is make the screen scroll a little further up, so there's some room for my dropdown to be shown. The windows phone UI design guidelines say: "When the keyboard is deployed, the application should scroll to ensure the active edit control and the caret are in view". This happens fine, it's just the non-active dropdown gets hidden behind the onscreen keyboard. The guidelines also say that an application can choose to show the onscreen keyboard, and can also choose to close it. At the moment i'm stuck, and I don't think (based on my research and the replies to this question) that it's possible to detect that the onscreen keyboard has been displayed. I'm moving my investigation to see if it's possible to determine the "visible area" of the page (width & height in pixels for example), and combine this with an onfocus for the textbox... not sure if this will prove fruitful though.

  • How to Pass complex objects in ASP.NET MVC using Get parameters?

    - by VJ
    I am wanting to pass something like the following to my view from my controller via GET not POST: public class MyDTO { public string val1 { get; set; } public string val2 { get; set; } public MyObject obj { get; set; } } public class MyObject { public int SomeInt { get; set; } public string ACoolValue { get; set; } public string YetAnotherCoolValue { get; set; } } And then the controller would like like this. (Note it is a GET): public ActionResult MyView(MyDTO dto) { return View(dto) } The problem is that the instance of MyObject is coming back as null, where val1 and val2 have data. Has anyone run across this?

  • MVC Pages that require the user to be logged in

    - by keithjgrant
    I'm working on a little MVC framework and I'm wondering what the "best way" is to structure things so secure pages/controllers always ensure the user is logged in (and thus automatically redirects to a login page--or elsewhere--if not). Obviously, there are a lot of ways to do it, but I'm wondering what solution(s) are the most common or are considered the best practice. Some ideas I had: Explicitly call user->isLoggedIn() at the beginning of your controller action method? (Seems far too easy to forget and leave an important page unsecure on accident) Make your controller extend a secureController that always checks for login in the constructor? Do this check in the model when secure information is requested? (Seems like redundant calls would be made) Something else entirely? Note: I'm working in PHP, though the question is not language-dependent.

  • User-customizable rails authorization

    - by neutrino
    Hello everyone, Seems there is an abundance of popular declarative-style authorization plugins, which allow you to somehow state in the code that, e.g., this controller action can be accessed by users with such-and-such roles. But what if I need a more dynamic scheme. I want to have an admin area, with a list of all authorizable actions and an ability to assign permissions on actions from the UI. I have ideas how to implement it from scratch, like to define a model corresponding to a controller and/or action and store the permissions via normal associations. Just wonder if there are any ready solutions to this. Thanks a lot

  • How to show specific link to user that's signed in and on specific page in rails?

    - by sevens
    I have the following code for part of my navigation: <% if user_signed_in? %> <li><%= link_to 'Edit Profile', edit_profile_path(current_user.profile) %></li> <li><%= link_to 'Edit Account', edit_user_registration_path %></li> <% elsif user_signed_in? and params[:controller] == 'profiles#edit' %> <li><%= link_to 'View Profile', profile_path(current_user.profile) %></li> <li><%= link_to 'Edit Account', edit_user_registration_path %></li> <% else %> <li><%= link_to 'Sign up', new_user_registration_path %></li> <% end %> I want different links to show depending on where the "user_signed_in" is. However, my <% elsif user_signed_in? and params[:controller] == 'profiles#edit' %> doesn't seem to be working. What am I doing wrong?

  • Error handling in controllers with MVC

    - by twrn
    Does it make sense to do error handling and logging inside actions methods or handle the OnException method inside the controllers. One way means writing try/catches in all the action methods even when there is nothing to be done to recover from the error. Handling this at the controller level would allow logging and redirection to an error handler page without writing try/catches inside all the action methods. Which method makes the most sense? Here is example code of try/catches in an action method. [HttpPost] public ActionResult Delete(int id) { using (new Tracer("Project Controller")) { try { Logger.Write("Deleting project"); projService.DeleteProject(id); TempData["message"] = "Project Deleted successfully"; } catch (System.Exception ex) { HandleException(ex, "Project could not be deleted."); } return RedirectToAction("List"); } }

  • How to call javascript function when url variable is sent

    - by mattlarkin
    Hello, heres basically what I need to get done. I have a jsp page which allows me to add/modify/delete an item. The items are stored in a database which I have controller classes to access(dont worry bout that part) When an item gets selected and deleted the id of the item gets sent to the controller to be processed. The item will not always be deleted if their is a foreign key constraint so I send either a delete=true or delete=false through url back to the jsp page. I would like to have it so a javascript function gets called displaying an alert saying the item was deleted or the item was not deleted. can someone please tell me the best way to do this? thank you

  • Where do I put constants file for Codeigniter (PHP)?

    - by wag2639
    I have a list of constants (I'm using them as an enum), some are define statements, and some are just global variables. Where am I suppose to put them in the MVC framework so I can use them for both my model and my controller that needs to reference it? I'd rather not stick it into config/constants.php since they shouldn't be called except for by this model and the controllers that use it. Edit 1: Clarification To be more specific, I have my message_model model and it has a bunch of constants that I need that are stored in message_model_constants.php. Where should I put message_model_constants.php and is there a way to have it automatically included by the controller that loads message_model when message_model is not (and I don't want it to be) auto-loaded. Edit 2: I really don't want to have the constants auto-loaded except for when I use the model

  • where to store temporary data in MVC 2.0 project

    - by StuffHappens
    Hello! I'm starting to learn MVC 2.0 and I'm trying to create a site with a quiz: user is asked a question and given several options of answer. If he chooses the right answer he gets some points, if he doesn't, he looses them. I tried to do this the following way public class HomeController : Controller { private ITaskGenerator taskGenerator = new TaskGenerator(); private string correctAnswer; public ActionResult Index() { var task = taskGenerator .GenerateTask(); ViewData["Task"] = task.Task; ViewData["Options"] = task.Options; correctAnswer= task.CorrectAnswer; return View(); } public ActionResult Answer(string id) { if (id == correctAnswer) return View("Correct") return View("Incorrect"); } } But I have a problem: when user answers the cotroller class is recreated and I loose correct answer. So what is the best place to store correct answer? Should I create a static class for this purpose? Thanks for your help!

  • PHP Shared Sessions across Domain

    - by bigstylee
    Hi, I have seen a few answers to this on SOO but most of these are concerned with the use of subdomains, of which none have worked for me. The common one being that the use of session.cookie_domain, which from my understanding will only work with subdomains. I am interested in a solution that deals with deals with entirely different domains (and includes the possibility of subdomains). Unfortunately project deadlines being what they are, time is not on my side, so I turn to SOO's expertise and experience. The current project brief is to be able to log into one site which currently only stores the user_id in the session and then be able to retrieve this value while on a different domain within the same server enviroment. Session data is being stored/retrieved from a database where the session id is the primary key. I am hoping to find a "light wieght" and "easy" to implement solution. The system is utlising an in-house Model View Controller design pattern, so all requests (including different domains) are run through a single bootstrap script. Using the domain name as a variable, this determines what context to display to the user. One option that did look like to have potential is the use of a hidden image and using the alt tag to set the user id. My first impressions suggest this immediately seems "too easy" (if possible) and riddled with security flaws. Disscuss? Another option which I considered is using the IP and User Agent for authentication but again I feel this not going to be a reliable option due to shared networks and changing IP addresses. My third option (and preferred) which I considered and as yet not seen discussed is using htaccess to fool the user into thinking that they are on a different domain when infact apache is redirecting; something like www.foo.com/index.php?domain=bar.com&controller=news/categoires/1 but displays to the user as www.bar.com/news/categories/1 foo.com represents the "main site domain" which all requests are run through and bar.com is what the user thinks they are accessing. The controller request dictates the page and view being requested. Is this possible? Are there other options? Pros/Cons? Thanks in advanced!!!

  • What's a good way to format AJAX responses? Or, using Django templating with AJAX

    - by synic
    In some of the code I'm working on, the author max AJAX calls to a Django view that returns JSON. Once the JSON is retrieved, it'll be injected into the page with a function that looks like this (note, this is a simplification, but I'm sure you know what I'm getting at here): function build_event_listing(events) { var html = ''; for(int i = 0; i < events.length; i++) { event = events[i]; html += "<h2>" + event.title + "</h2>\n"; html += "<p>" + event.description + "</p>"; html += "Click <a href='/event/view/" + event.id + "'>here<a> for more info."; } events_div.html(html); } I really don't like this approach. To change the look of each event listing, the designer would have to modify that ugly JS. I'd much rather make use of Django's templating system, but I'm wondering how I can do this? I had the idea of writing the view like this: def view_listings(req): events = models.Event.objects.all() html = [] for event in events: html.append( render_to_string('event/single_event.html', { 'event': event, }, context_instance=RequestContext(req)) return HttpResponse(''.join(html), mimetype='text/html') ... but it just seems like there should be a better way. Any ideas?

  • Imitating Multiple Inheritance in PHP

    - by fabieno
    I am working on my own MVC framework and found myself stuck. I need the following construction: Controller -- Backend_Controller -- Backend_Crud_Controller -- Frontend_Controller -- Frontend_Crud_Controller Both 'Backend_Crud_Controller' and 'Frontend_Crud_Controller' have the same functionality and thus they should extend another class named 'Base_Crud_Controller', the only difference comes from the 'Backend/Frontend' Controllers which implement different mechanisms. Basically they should inherit both classes but my problem is that 'Backend/Frontend' controller doesn't necessarily extend 'Base_Crud_Controller'. I know multiple inheritance doesn't exist in PHP but I am looking for a solution, I choose to refrain Mixins (like in Symfony) as I don't consider that an elegant solution. Interfaces do not suit me as all of these end up as concrete classes that should implement methods.

  • GridView edit problem If primary key is editable (design problem)

    - by Nassign
    I would like to ask about the design of table based on it's editability in a Grid View. Let me explain. For example, I have a table named ProductCustomerRel. Method 1 CustomerCode varchar PK ProductCode varchar PK StoreCode varchar PK Quantity int Note text So the combination of the CustomerCode, StoreCode and ProductCode must be unique. The record is displayed on a gridview. The requirement is that you can edit the customer, product and storecode but when the data is saved, the PK constraint must still persist. The problem here is it would be natural for a grid to be able to edit the 3 primary key, you can only achieve the update operation of the grid view by first deleting the row and then inserting the row with the updated data. An alternative to this is to just update the table and add a SeqNo, and just enforce the unique constraint of the 3 columns when inserting and updating in the grid view. Method 2 SeqNo int PK CustomerCode varchar ProductCode varchar StoreCode varchar Quantity int Note text My question is which of the two method is better? or is there another way to do this?

  • JSON to display text -- Freezes UI

    Hi everyone, I currently have a very simple view which displays info from a JSON feed. The problem I'm facing is the few second pause I encounter once I press this tab.
