  • Kohana controller shows blank page if missing URI segment/argument

    - by Petruza
    When accessing http://www.nowplayingnashville.com/event2/detail/440698386/Whatever the controller shows normally. But when omitting the last parameter (event's title, which can be any string), http://www.nowplayingnashville.com/event2/detail/440698386/ It shows blank. I added a default value and tried to hardcode the title on the first line of the controller, but it doesn't work anyway. It looks like a view issue, because I can add an echo at the end of the controller and it gets printed, so the controller is executing to the end, but the views aren't displayed. This problem is present on the live site, but I checked out the code on my local machine and it works perfectly without a title. That's strange. Could it be a Kohana or Apache configuration issue?

  • How Does Differential Execution Work?

    - by Brian
    I've seen a few mentions of this on SO, but staring at Wikipedia and at an MFC dynamic dialog demo did nothing to enlighten me. Can someone please explain this? Learning a fundamentally different concept sounds nice. Edit: I think I'm getting a better feel for it. I guess I just didn't look at the source code carefully enough the first time. I have mixed feelings about DE at this point. On the one hand, it can make certain tasks considerably easier. On the other hand, getting it up and running (i.e. setting it up in your language of choice) is not easy (I'm sure it would be if I understood it better)...though I guess the toolbox for it need only be made once, then expanded as necessary. I think in order to really understand it, I'll probably need to try implimenting it in another language.

  • css Checkbox Label Selector

    - by HW90
    I'm developing a MVC3 application and need to select the checkboxes label. In ASP MVC3 you have helper methods which creat a part of the code. So the code for a checkbox looks like this: <input id="Jumping_successleicht" type="checkbox" value="true" name="Jumping_successleicht"> <input type="hidden" value="false" name="Jumping_successleicht"> <label for="Jumping_successleicht"> <span>leicht (4)</span> </label> Now I've thought I can use following code to select the label: input[type=checkbox] + label { background: url("../../Images/Controls/Checkbox.png") no-repeat scroll left center transparent; clear: none; cursor: pointer; margin: 0; padding: 5px 0 4px 24px; } But it does not work. It looks like label and input have to be next to each other. Does any ony have a solution how to solve this problem?

  • Use different updatetargetid based on view

    - by Jerrie Pelser
    I have a web page which display a list of items in a HTML table. Above the list is a form which allows the user to add a new item to the list via AJAX (using Ajax.BeginForm). When the data is posted to the controller via AJAX I add the new item to the database backend and generate a new table row via a Partial View which then gets appended to the exisiting table. When the form to add new items however contains errors, I want to render the form back to the web browser and display that. So here is the question: Is it possible to specify the UpdateTargetId from within the controller? At the moment whatever View I return from the controller gets inserted in the same target, but I would like to update a different target (ie. different UpdateTargetId) based on whatever view was returned from the controller. Any help would be appreciated...

  • Creating DOM elements on the fly - check if the data is not harmful

    - by user313353
    I already posted a question closely related to the this one. I watched the Mix10 video with P. Haacked and S. Hanselman. I am building an AJAX-powered site whose input forms are created on the fly. All the code to accomplish this is done within a script tag or a javascript file. For example the following DOM elements are created when the page loads and are wrapped into an existing div defined in a view: $('#myform').append('); $('#myform').append(''); When I click the submit button I need to get the values of the input form whose id is 'Name': $("#Name").val() and then I return a Json object: { Name: name }; For this kind of scenario there is no way to use Html.Encode() or AntiXss.HtmlEncode() on the client-side. The only way to check if the input is not harmful is done on the server-side (via a service layer). This seems a limitation. All is fine if and only if a view has a set of predefined inputs. When it is time to create them on the fly, the situation is different. Have you thought of that situation guys? Thanks for the attention you have put on this. Roland Brussels, Belgium

  • JQuery: How do you use live with the post function

    - by Luke101
    When load the new html from a post function I lose all of my click bindings. I read that i could use live to keep all the bindings but can't find any examples where live is used with post. Here is my code: var AddGroup = function (Obj) { $('.Selectiontarget').live('post', function () { $.post('/List/AddGroupItem?ListID=' + Obj, function (data) { $('.Selectiontarget').html(data); }); }); } When I run this code I lose all of my click bindings.

  • Can i change the view without changing the controller?

    - by Ian Boyd
    Pretend1 there is a place to type in a name:     Name: __________________ When the text box changes, the value is absorbed into the controller, who stores it in data model. Business rules require that a name be entered: if there is no text entered the TextBox should be colored something in the view to indicate baddness; otherwise it can be whatever color the view likes. The TextBox contains a String, the controller handles a String, and the model stores a String. Now lets say i want to improve the view. There is a new kind of text box2 that can be fed not only string-based keyboard input, but also an image. The view (currently) knows how to determine if the image is in the proper format to perform the processing required to extract text out of it. If there is text, then that text can be fed to the controller, who feeds it to the data model. But if the image is invalid, e.g.3 wrong file format invalid dimensions invalid bit depth unhandled or unknown encoding format missing or incorrectly located registration marks contents not recognizable the view can show something to the user that the image is bad. But the telling the user that something is bad is supposed to be the job of the controller. i'm, of course, not going to re-write the controller to handle Image based text-input (e.g. image based names). a. the code is binary locked inside a GUI widget4 b. there other views besides this one, i'm not going to impose a particular view onto the controller c. i just don't wanna. If i have to change things outside of this UI improvement, then i'll just leave the UI unimproved5 So what's the thinking on having different views for the same Model and Controller? Nitpicker's Corner 1 contrived hypothetical example 2 e.g. bar code, g-mask, ocr 3 contrived hypothetical reasons 4 or hardware of a USB bar-code scanner 5 forcing the user to continue to use a DateTimePicker rather than a TextBox

  • .submit() changes post data

    - by ajbeaven
    I'm posting a form with javascript and it seems to be changing a value that I've entered in. Html: <% using (Html.BeginForm("ChangeTime", "Cart", new { cartItemId = cartItem.CartItemID }, FormMethod.Post, null)) { %> <%= Html.TextBox("startTime")%> <input type="submit" value="Update" /> <% } %> JQuery: <script type="text/javascript"> $('#startTime').change(function() { $(this).parent('form').submit(); }); </script> When I put a time in the textbox (05/05/2010 06:08 am), the form is submitted, however the string as it comes through, is 05/05/2010 - with the time part removed. I see this in fiddler. If get rid of the javascript and click the button above, it goes through how it should. Why is JQuery changing my text?

  • JSON.Stringify data including boolean values

    - by ancdev
    What I'm trying to do is to pass JSON object to a WebAPI ajax call and mapped to a strongly typed object on the server side. String values are being posted perfectly however when it comes to boolean values, they are not being passed at all. Below is my code: var gsGasolineField = $('.gsGasoline').val(); blData = { Gasoline: gsGasolineField }; var json = JSON.stringify(blData); $.ajax({ type: "POST", url: url, data: json, contentType: "application/json", dataType: "json", statusCode: { 201 /*Created"*/: function (data) { $("#BusinessLayerDialog").dialog("close"); ClearForm("#BusinessLayerForm"); }, 400: /*Bad request - validation error*/ function (data) { $("#BusinessLayerForm").validate().form(); }, 500: function (data) { alert('err'); } }, beforeSend: setHeader }); Gasoline property is of type boolean on the server side.

  • Ignore route with a specific parameter

    - by Vivien
    Hello, I have an @url.Action in which I pass a parameter to the action. When the parameter is null, I would like to just do nothing and stay on the same page. What I have done is the following: routes.MapRoute( null, "Test/View/{Id}", new { controller = "Test", action = "View" }, new { Id = @"\d+" } //id must be numerical ); routes.IgnoreRoute("Test/View/{*pathInfo}"); The action is not executed but my problem is that I get this: Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly. Requested URL: /Test/View Which I obvisouly do not want to see. Thanks for your help.

  • Newbie question on MvcContrib TestHelpers

    - by Simon Lomax
    Hi, I'm just starting to use the TestHelpers in MvcContrib. I want to try and test an action method on my controller that itself tests if IsAjaxRequest() is true. I've used the same code that is shown in the TestHelper samples to set up the TestControllerBuilder _controller = new StarsController(); _builder = new TestControllerBuilder(); _builder.InitializeController(_controller); So that _controller has all the faked/mocked HttpContext inside it, which is really great. But what do I do now to force IsAjaxRequest() on the internally faked Request object to return true?

  • Rails - Scalable calculation model

    - by H O
    I currently have a calculation structure in my rails app that has models metric, operand and operation_type. Presently, the metric model has many operands, and can perform calculations based on the operation_type (e.g. sum, multiply, etc.), and each operand is defined as being right or left (i.e. so that if the operation is division, the numerator and denominator can be identified). Presently, an operand is always an attribute of some model, e.g. @customer.sales.selling_price.sum. In order to make this scalable, in need to allow an operand to be either an attribute of some kind, or the results of a previous operation, i.e. an operand can be a metric. I have included a diagram of how my models currently look: Can anyone assist me with the most elegant way of allowing an operand to be an actual operand, or another metric? Thanks! EDIT: It seems based on the only answer so far that perhaps polymorphic associations are the way to go on this, but the answer is so brief I have no idea how they could be used in this way - can anyone elaborate? EDIT 2: OK, I think I'm getting somewhere - essentially i presently have a metric, which has_many operands, and an operand has_many metrics. I need a polymorphic self join, where a metric can also have many metrics - do I need to call this something else, perhaps calculated_metrics, so that the metric model can use itself? That would leave me with a situation where a metric has_many operands, and a metric has many calculated_metrics.
