  • How to make my URL mapping case insensitive?

    - by fabien7474
    Grails, by default, is case-sensitive when mapping URL to controller actions or views. For instance, www.mywebsite.com/book/list will work BUT www.mywebsite.com/Book/list will return a 404 page. What can I do (code snippets are welcomed) to make my URL case-insensitive (i.e. www.mywebsite.com/Book/list being a valid url) ?

  • How to explictely obtain post data in Spring MVC?

    - by predhme
    Is there a way to obtain the post data itself? I know spring handles binding post data to java objects. But if I had two fields that I want to process manually, how do I obtain that data? Assuming I had two fields in my form <input type="text" name="value1" id="value1"/> <input type="text" name="value2" id="value2"/> How would I go about retrieving those values in my controller?

  • MVC Model State

    - by gnome
    Greetings On all my controllers I recycle the same code that wraps my models and to accesses the service layer -- and I'm tired for copy / pasting it into each controller: private IProjectService _service; public New() { _service = new ProjectService(new ModelValidation(this.ModelState)); } public New(IProjectService service) { _service = service; } Is there someplace where I can place this where all my controllers access it?

  • Memory allocation and release for UIImage in iPhone?

    - by rkbang
    Hello all, I am using following code in iPhone to get smaller cropped image as follows: - (UIImage*) getSmallImage:(UIImage*) img { CGSize size = img.size; CGFloat ratio = 0; if (size.width < size.height) { ratio = 36 / size.width; } else { ratio = 36 / size.height; } CGRect rect = CGRectMake(0.0, 0.0, ratio * size.width, ratio * size.height); UIGraphicsBeginImageContext(rect.size); [img drawInRect:rect]; UIImage *tempImg = [UIGraphicsGetImageFromCurrentImageContext() retain]; UIGraphicsEndImageContext(); return [tempImg autorelease]; } - (UIImage*)imageByCropping:(UIImage *)imageToCrop toRect:(CGRect)rect { //create a context to do our clipping in UIGraphicsBeginImageContext(rect.size); CGContextRef currentContext = UIGraphicsGetCurrentContext(); //create a rect with the size we want to crop the image to //the X and Y here are zero so we start at the beginning of our //newly created context CGFloat X = (imageToCrop.size.width - rect.size.width)/2; CGFloat Y = (imageToCrop.size.height - rect.size.height)/2; CGRect clippedRect = CGRectMake(X, Y, rect.size.width, rect.size.height); //CGContextClipToRect( currentContext, clippedRect); //create a rect equivalent to the full size of the image //offset the rect by the X and Y we want to start the crop //from in order to cut off anything before them CGRect drawRect = CGRectMake(0, 0, imageToCrop.size.width, imageToCrop.size.height); CGContextTranslateCTM(currentContext, 0.0, drawRect.size.height); CGContextScaleCTM(currentContext, 1.0, -1.0); //draw the image to our clipped context using our offset rect //CGContextDrawImage(currentContext, drawRect, imageToCrop.CGImage); CGImageRef tmp = CGImageCreateWithImageInRect(imageToCrop.CGImage, clippedRect); //pull the image from our cropped context UIImage *cropped = [UIImage imageWithCGImage:tmp];//UIGraphicsGetImageFromCurrentImageContext(); CGImageRelease(tmp); //pop the context to get back to the default UIGraphicsEndImageContext(); //Note: this is autoreleased*/ return cropped; } I am using following line of code in cellForRowAtIndexPath to update the image of the cell: cell.img.image = [self imageByCropping:[self getSmallImage:[UIImage imageNamed:@"goal_image.png"]] toRect:CGRectMake(0, 0, 36, 36)]; Now when I add this table view and pop it from navigation controller, I see a memory hike.I see no leaks but memory keeps climbing. Please note that the images changes for each row and I am creating the controller using lazy initialization that is I create or alloc it whenever I need it. I saw on internet many people facing the same issue, but very rare good solutions. I have multiple views using the same way and I see almost memory raised to 4MB within 20-25 view transitions. What is the good solution to resolve this issue. tnx.

    Hello I would like to show a fixed number of sections in a table view with a Fetched Results Controller as the data source.

  • ASP.NET MVC & Web Services

    - by ANaimi
    Hello, Does adding a Web Service to my ASP.NET MVC project break the whole concept of MVC? That Web Service (WCF) depends on the Model layer from my MVC project to communicate with the back-end (so it looks to me like it needs to be part of the MVC solution). Should I add this to the Controller or Model layer?

  • Ajax problem after deleting a div, then creating a new one

    - by Matt Nathanson
    I'm building a custom CMS where you can add and delete clients using ajax and jquery 1.4.2. My problem lies after I delete a div. The ajax is used to complete this and refresh automatically.. But when I go to create a new div (without a hard refresh) it puts it back in the slot of the div I just deleted. How can I get this to completely forget about the div i just deleted and place the new div in the next database table? link for reference: http://staging.sneakattackmedia.com/cms/ //Add New client // function AddNewClient() { dataToLoad = 'addClient=yes'; $.ajax({ type: 'post', url: '/clients/controller.php', datatype: 'html', data: dataToLoad, target: ('#clientssidebar'), async: false, success: function(html){ $(this).click(function() {reInitialize()}); //$('#clientssidebar').html(html); $('div#' + clientID).slideDown(800); $(this).click(function() { ExpandSidebar()});}, error: function() { alert('An error occured! 222');} });}; //Delete Client // function DeleteClient(){ var yes = confirm("Whoa there chief! Do you really want to DELETE this client?"); if (yes == 1) { dataToLoad = 'clientID=' + clientID + '&deleteClient=yes', $.ajax({ type: 'post', url: '/clients/controller.php', datatype: 'html', data: dataToLoad, success: function(html) { alert('Client' + clientID + ' should have been deleted from the database.'); $(this).click(function() {reInitialize()}); $('div#' +clientID).slideUp(800); }, error: function() { alert('error'); }});};}; //Re Initialize // function reInitialize() { $('#addnew').click(function() {AddNewClient()}); $('.deletebutton').click(function() {clientID = $(this).parent().attr('id'); DeleteClient()}) $('.clientblock').click(function() {clientID = $(this).attr('id'); ExpandSidebar()});}; //Document Ready // $(document).ready(function(){ if ($('isCMS')){ editCMS = 1; $('.deletebutton').click(function() {clientID = $(this).parent().attr('id'); DeleteClient()}); $('#addnew').click(function() {AddNewClient()}); $('.clientblock').click(function() {clientID = $(this).attr('id'); ExpandSidebar()}); $('.clientblock').click(function() {if (clickClient ==true) { $(this).css('background-image', 'url(/images/highlightclient.png)'); $(this).css('margin-left' , '30px'); }; $(this).click(function(){ $(this).css('background-image', ''); }); $('.uploadbutton').click(function(){UploadThings()}); }); } else ($('#clientscontainer')) { $('#editbutton').css('display', 'none'); }; }); Please help!!!

  • ASP.NET MVC : Good Replacement for User Control?

    - by David Lively
    I found user controls to be incredibly useful when working with ASP.NET webforms. By encapsulating the code required for displaying a control with the markup, creation of reusable components was very straightforward and very, very useful. While MVC provides convenient separation of concerns, this seems to break encapsulation (ie, you can add a control without adding or using its supporting code, leading to runtime errors). Having to modify a controller every time I add a control to a view seems to me to integrate concerns, not separate them. I'd rather break the purist MVC ideology than give up the benefits of reusable, packaged controls. I need to be able to include components similar to webforms user controls throughout a site, but not for the entire site, and not at a level that belongs in a master page. These components should have their own code not just markup (to interact with the business layer), and it would be great if the page controller didn't need to know about the control. Since MVC user controls don't have codebehind, I can't see a good way to do this. Update FINALLY, a good (and, in retrospect, obvious) way to accomplish this. using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; namespace K.ObjectModel.Controls { public class TestControl : ViewUserControl { protected override void Render(System.Web.UI.HtmlTextWriter writer) { writer.Write("Hello World"); base.Render(writer); } } } Create a new class which inherits ViewUserControl Override the .Render() method as shown above. Register the control via its associated ASCX as you would in a webForm: <%@ Register TagName="tn" TagPrefix="k" Src="~/Views/Navigation/LeftBar.ascx"%> Use the corresponding tag in whatever view or master page that you need: <k:tn runat="server"/> Make sure your .ascx inherits your new control: <%@ Control Language="C#" Inherits="K.ObjectModel.Controls.TestControl" %> Voila, you're up and running. This is tested with ASP.NET MVC 2, VS 2010 and .NET 4.0. Your custom tag references the ascx partial view, which inherits from the TestControl class. The control then overrides the Render() method, which is called to render the view, giving you complete control over the process from tag to output. Why does everyone try to make this so much harder than it has to be?

  • Active directory logonCount is 0, though the user has logged in

    - by Arun
    For a user in active directory, the properties hold values for lastlogontime & lastlogontimestamp but the logoncount is 0. I am having only one domain controller in that domain. I found from surfing, that logonCount value of 0 indicates that the value is unknown. But I am totally confused with why it is unknown. Is that an issue with AD.

  • Creating a generic NotFound View in ASP.MVC

    - by George
    Hello guys, I'm having a problem to create a generic View to represent NotFound pages. The view is created and it's fine. I need to know how i can direct the user to the NotFound view in my Controllers and how to render a specific "Return to Index" in each controller. Here is some code: public class NotFoundModel { private string _contentName; private string _notFoundTitle; private string _apologiesMessage; public string ContentName { get; private set; } public string NotFoundTitle { get; private set; } public string ApologiesMessage { get; private set; } public NotFoundModel(string contentName, string notFoundTitle, string apologiesMessage) { this._contentName = contentName; this._notFoundTitle = notFoundTitle; this._apologiesMessage = apologiesMessage; } } // NotFound View <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Geographika.Models.NotFoundModel>" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> <%= Html.Encode(Model.ContentName) %> </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2><%= Html.Encode(Model.NotFoundTitle) %></h2> <p><%= Html.Encode(Model.ApologiesMessage) %></p> <!-- How can i render here a specific "BackToIndexView", but that it's not bound to my NotFoundModel? --> </asp:Content> // Controller piece of code // // GET: /Term/Details/2 public ActionResult Details(int id) { Term term = termRepository.SingleOrDefault(t => t.TermId == id); if (term == null) return View("NotFound"); // how can i return the specific view that its not bound to Term Model? // the idea here would be something like: // return View("NotFound",new NotFoundModel("a","b","c")); else return View("Details", term); } I'm not sure how to redirect to a whole different page. Can anyone give me any pointers? Thanks

  • Can the memory used by MKMapView be released some how?

    - by gdr
    I am using an MKMapView in my iPhone application. When I load this view, the activity monitor instrument shows that the real memory of my App is increasing significantly. It keeps going up as you move the map around or zoom in and out. Once the View controller that loads this view is removed, the memory that was allocated due to the usage of the mapView does not get freed up. Is there something that can be done to get all this memory back?
