  • Custom view in iPhone SDK gets placed incorrectly in realation to statusbar

    - by markqvist
    (ragh, i'm apparently not allowed to post images, so i have included links to the images in this post instead of embedding them) Im writing an iPhone application based on the navigation controller template, but I am not loading the actual navigation controller as the first view in the window. I create a new view controller from a xib, and then add that as a subview, and then only push the navigation view as a modal when i need it. Here's my application: didFinishLaunching ... method in the application deleate RootViewController *rootViewController = (RootViewController *)[navigationController topViewController]; rootViewController.managedObjectContext = self.managedObjectContext; mainViewController = [[MainViewController alloc] initWithNibName:@"MainViewController" bundle:[NSBundle mainBundle]]; mainViewController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [window addSubview:[mainViewController view]]; [[mainViewController view] setNeedsLayout]; [window makeKeyAndVisible]; return YES; It works but the view is not properly aligned with the statusbar: http://img.exdev.dk/1.png When i click "my ambiances" and push the navigation controller view, and then dismiss it again, the layout is fine: same link as above, just replace the 1 with a 2. Sorry for the hassle, apparently I can also only post one link.... Here's the code I use for presenting/dismissing the navigationcontroller: -(void)pushMyAmbiences { [mainViewController presentModalViewController:navigationController animated:TRUE]; } -(void)returnToMainView { [mainViewController dismissModalViewControllerAnimated:TRUE]; } Is there anything I'm missing here? Layout-wise? Something that needs to be set in the xib? In a vain attempt I tried calling setNeedsLayout on the view, no luck. Any help is greatly appreciated!

  • Serious Application Error

    - by Garry
    I have a TableView controller class that uses a fetched results controller to display a list of 'patient' entities taken from a Core Data model. The sections of this table are taken from a patient attribute called 'location'. Here is the sort descriptor for the fetch request: NSSortDescriptor *locationDescriptor = [[NSSortDescriptor alloc] initWithKey:@"location" ascending:YES]; NSSortDescriptor *lastNameDescriptor = [[NSSortDescriptor alloc] initWithKey:@"lastName" ascending:YES]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:locationDescriptor, lastNameDescriptor, nil]; Here is the initialisation code for the FRC: NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:managedObjectContext sectionNameKeyPath:@"location" cacheName:@"List"]; When I want to add a new 'patient' entity - I click an add button which then pushes an 'add new patient' view controller to the navigation stack. The first patient I add works fine. If I add a second patient - the app will sometimes crash with the following error: 2010-03-22 14:42:05.270 Patients[1126:207] Serious application error. Exception was caught during Core Data change processing: * -[NSCFArray insertObject:atIndex:]: index (1) beyond bounds (1) with userInfo (null) 2010-03-22 14:42:05.272 Patients[1126:207] Terminating app due to uncaught exception 'NSRangeException', reason: '** -[NSCFArray insertObject:atIndex:]: index (1) beyond bounds (1)' This only seems to happen if the patient's have a location added (if none is added then the location defaults to 'unknown'). It seems to have something to do with the sorting of the location too. For instance, if the first patient location = ward 14 and the second = ward 9 then it crashes without fail. I'm wondering if this is something to do with how I am asking the fetched results controller to sort the section names?? This bug is driving me nuts and I just can't figure it out. Any help would be greatly appreciated!

  • How to get all active parameters in ASP.NET MVC (2)

    - by SztupY
    Hi! I was wondering whether there is a way to create an ActionLink or similar, that changes only a few parameters of the actual query, and keeps all the other parameters intact. For example if I'm on an URL like http://example.com/Posts/Index?Page=5&OrderBy=Name&OrderDesc=True I want to change only the Page, or OrderBy parameter and keep all other parameters the same, even those I don't yet know of (like when I want to add a Search parameter or something similar too). The header of my current action looks like this: public ActionResult Index(int? Page, string OrderBy, bool? Desc) and I'm only interested in the values that this controller "eats". I want however that when I extend this action (for example with a string Search parameter) the links should work the same way as before. Here is what I did already: Create a new RouteValueDictionary and fill it with everything from RouteData.Values Problem: This only fills the parameters that are used in the Routing, so all other optional parameters (like Page) to the controller are lost Add everything from HttpContext.Request.QueryString to the previous dictionary This is what I am currently using Problem: It might have some junk stuff, that the Controller didn`t ask for, and it doesn't work if the page was loaded using POST. You also don't have any ModelBindings (but this isn't much of a problem, because we are re-sending everything anyway) Use HttpContext.Request.Params Problem: this has too much junk data which imho one shouldn't add to a RouteValueDictionary that is passed to an ActionLink So the questions: Is there an RVD that has all the data that was passed to the Controller and was used by it? Is this solution good, or are there any caveats I didn't think about (mainly in the context of changing a few query parameters while keeping the others intact)? Is there a way to filter out the "junk" data from the Params object?

  • cakephp: Custom Authentication Object authenticate not called

    - by Kristoffer Darj
    The method authenticate in a Custom Authentication Object is never called. Is this a glicth or am I missing something? I don't get anything in the log, I'm just redirected to users/login (or the one I specified) CakeVersion: 2.4.1 <?php //My custom Auth Class //Path: app/Controller/Component/Auth/HashAuthenticate.php App::uses('BaseAuthenticate', 'Controller/Component/Auth'); class HashAuthenticate extends BaseAuthenticate { public function authenticate(CakeRequest $request, CakeResponse $response) { //Seems to not be called CakeLog::write('authenticate'); debug($this); die('gaah'); } } If I add the method getUser() (or unauthenticated() ), those gets called however so at least I know that cake finds the class and so on. It just skips the authenticate-method. The AppController looks like this class AppController extends Controller { public $helpers = array('Html', 'Form', 'Session'); public $components = array('Auth' => array( 'authenticate' => array('Hash'), 'authorize' => array('Controller'), ) ); } I found a similar question here: CakePHP 2.x custom "Authentication adapter &quot;LdapAuthorize&quot; was not found but there the issue was typos.

  • Kohana 3 jQuery/AJAX request not working

    - by dscher
    I am trying to post some data to a controller in Kohana 3 using the jQuery AJAX method. I seem to have an issue with the data not getting to where I want it to be. I want the data to go to the /application/classes/controller/stock.php file where the file will process the data. I can't seem to figure this one out. Hopefully someone can help. My jQuery ajax call is: $.ajax({ type: 'POST', url: 'add_stock', data: { 'links': 'link_array' } }); 'add_stock' is the name of the action within the controller. I didn't know what else to try. I've also tried '.' and './' hoping that would be right but it's not. In Firebug, although it says the request was 200 OK, I see that the "RESPONSE" is "Failed to load source for: http://localhost/ddm/v2/stocks/add_stock" and my script in my controller which grabs the data isn't working. Here is that code in case it helps: $links = $_POST['links']; $link_obj = Jelly::factory('link') ->set('stock', $stock->id) ->set('links', $links); $link_obj->save(); I think that the problem is that I'm giving the ajax call the ROUTE and not the actual page it needs to deliver the POST data to. I just can't figure it out here. Any help?

  • problems with build params for accepts_nested_attributes_for

    - by holden
    I'm trying to add the user_id to a nested attribute that gets built by a parent controller but it doesn't seem to have the desired effect? Ie. I have a model called Place.rb which accepts_nested_attributes_for :reviews The nested attribute works fine and I build it inside the Places controller like so... @review = @place.reviews.build(:user_id => current_user.id) I was previously adding the user thru the form, but would like to do it thru the controller so that it only adds the user_id on creation, as it might get updated by someone else and i don't want the update changing the user_id... old way which works: <%= e.label :content, "Review" %><br /> <%= e.text_area :content, :rows => 20, :class => 'jquery_ckeditor' %><br /> <%= e.hidden_field :user_id, :value => current_user.id %> but thru the controller the build method with options has no effect? Any ideas? Can I not do this thru the build?

  • PoptorootViewController fails then removes all Viewcontrollers

    - by Spyker
    Trying to fix a very strange error, i have 3 view controllers that start from the app delegate and push each other accordingly. The 3rd view controller then has a toolbar button that calls the code here: -(void)showEventBrowser; { accelManeger.delegate = nil; NSLog(@"%u",[self.navigationController.viewControllers count]); [self.navigationController popToRootViewControllerAnimated:NO]; } This works the first time round but when i come back to this view controller and try again. Firstly it reports that there are 3 view controllers on the stack. It then deallocs the 2nd view controller in the stack and doesnt crash but will not go any further. If i hit the button again it says there are no view controllers on the stack and fails to respond. I have logs for all the viewdid, viewwill, e.t.c in each view controller and there appears to be no odd behaviour. Also no memory warnings from any view controllers. Why would this work once through but not the second time ?

  • ASP.NET MVC Strongly Typed Widgets

    - by Ben
    I have developed a plugin system that makes it easy to plug in new logic to an application. Now I need to provide the ability to easily add UI widgets. There are already some good responses on how to create a portal system (like iGoogle) with ASP.NET MVC, and I'm fine about the overall concept. My question is really about how we make strongly typed widgets. Essentially when we set up a widget we define the controller and action names that are used to render that widget. We can use one controller action for widgets that are not strongly typed (since we just return PartialView(widgetControlName) without a model) For widgets that are strongly typed (for example to an IList) we would need to add a new controller action (since I believe it is not possible to use Generics with ActionResult e.g. ActionResult). The important thing is that the widget developers should not change the main application controllers. So my two thoughts are this: Create new controllers in a separate class library Create one partial WidgetController in the main web project and then extend this in other projects (is this even possible?) - not possible as per @mfeingold As far as the development of the widgets (user controls) go, we can just use post build events from our extension projects to copy these into the Views/Widgets directory. Is this a good approach. I am interested to here how others have handled this scenario. Thanks Ben P.S - in case it helps, an example of how we can render widgets - without using Javascript <%foreach (var widget in Model) {%> <%if (widget.IsStronglyTyped) { Html.RenderAction(widget.Action, widget.Controller); } else { Html.RenderPartial(widget.ControlName); } %> <%} %>

  • Destroying nested resources in restful way

    - by Alex
    I'm looking for help destroying a nested resource in Merb. My current method seems near correct, but the controller raise an InternalServerError during the destruction of the nested object.

  • C# Reflection StackTrace get value

    - by John
    I'm making pretty heavy use of reflection in my current project to greatly simplify communication between my controllers and the wcf services. What I want to do now is to obtain a value from the Session within an object that has no direct access to HttpSessionStateBase (IE: Not a controller). For example, a ViewModel. I could pass it in or pass a reference to it etc. but that is not optimal in my situation. Since everything comes from a Controller at some point in my scenario I can do the following to walk the sack to the controller where the call originated, pretty simple stuff: var trace = new System.Diagnostics.StackTrace(); foreach (var frame in trace.GetFrames()) { var type = frame.GetMethod().DeclaringType; var prop = type.GetProperty("Session"); if(prop != null) { // not sure about this part... var value = prop.GetValue(type, null); break; } } The trouble here is that I can't seem to work out how to get the "instance" of the controller or the Session property so that I can read from it.

  • Is this a tableView issue or a CoreData Issue

    - by monotreme
    I have a CoreData-driven navigation app and I'm trying to figure out why It's crashing. I've got a hierarchy which is 3 view Controllers deep, all related by coredata relatioships, like this. TableViewA =relationship= TableViewB =relationship= TableViewC I'm honestly a novice at core data and I think my problem lies in the fetched results controller. I have one in TableViewA and another in TableViewB, and no matter how deep I go, the console always cites TableViewB's fetched results controller methods after a crash. Is this the problem? What's happening specifically is if I launch my app and drill down into the hierarchy of one record, let's call it Record1, I can delete sub records to my hearts content. Gone! no problem! But the second I go back to TableViewA and drill down into a different record, let's call that one Record2, and try to delete it's subrecords my app crashes, with the console citing this code from TableViewB as the problem. - (void)controllerWillChangeContent:(NSFetchedResultsController *)controller { // The fetch controller is about to start sending change notifications, so prepare the table view for updates. [self.tableView beginUpdates]; } When I go into the debugger, the specific method it always has a problem with is: if (![x.managedObjectContext save:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } Just a confirmation of my idiocy with CoreData is all I'm looking for I think. Oh and how many ManagedObjectContexts should I have in an app of this type. I've been told I should have separate ones for adding content, which then should re-integrate into the main one. Is this true? Thanks!

  • Wildcard subdomain .htaccess and Codeigniter

    - by Gautam
    Hi All, I am trying to create the proper .htaccess that would allow me to map as such: http://domain.com/ --> http://domain.com/home http://domain.com/whatever --> http://domain.com/home/whatever http://user.domain.com/ --> http://domain.com/user http://user.domain.com/whatever --> http://domain.com/user/whatever/ Here, someone would type in the above URLs, however internally, it would be redirecting as if it were the URL on the right. Also the subdomain would be dynamic (that is, http://user.domain.com isn't an actual subdomain but would be a .htaccess rewrite) Also /home is my default controller so no subdomain would internally force it to /home controller and any paths following it (as shown in #2 example above) would be the (catch-all) function within that controller. Like wise if a subdomain is passed it would get passed as a (catch-all) controller along with any (catch-all) functions for it (as shown in #4 example above) Hopefully I'm not asking much here but I can't seem to figure out the proper .htaccess or routing rules (in Codeigniter) for this. httpd.conf and hosts are setup just fine. EDIT #1 Here's my .htaccess that is coming close but is messing up at some point: RewriteEngine On RewriteBase / RewriteCond %{SCRIPT_FILENAME} !-d RewriteCond %{SCRIPT_FILENAME} !-f RewriteCond %{HTTP_HOST} ^([a-z0-9-]+).domain [NC] RewriteRule (.*) index.php/%1/$1 [QSA] RewriteCond $1 !^(index\.php|images|robots\.txt) RewriteRule ^(.*)$ /index.php/$1 [L,QSA] With the above, when I visit: http://test.domain/abc/123 this is what I notice in $_SERVER var (I've removed some of the fields): Array ( [REDIRECT_STATUS] => 200 [SERVER_NAME] => test.domain [REDIRECT_URL] => /abc/123 [QUERY_STRING] => [REQUEST_URI] => /abc/123 [SCRIPT_NAME] => /index.php [PATH_INFO] => /test/abc/123 [PATH_TRANSLATED] => redirect:\index.php\test\test\abc\123\abc\123 [PHP_SELF] => /index.php/test/abc/123 ) You can see the PATH_TRANSLATED is not properly being formed and I think that may be screwing things up?

  • MVC design question for forms

    - by kenny99
    Hi, I'm developing an app which has a large amount of related form data to be handled. I'm using a MVC structure and all of the related data is represented in my models, along with the handling of data validation from form submissions. I'm looking for some advice on a good way to approach laying out my controllers - basically I will have a huge form which will be broken down into manageable categories (similar to a credit card app) where the user progresses through each stage/category filling out the answers. All of these form categories are related to the main relation/object, but not to each other. Does it make more sense to have each subform/category as a method in the main controller class (which will make that one controller fairly massive), or would it be better to break each category into a subclass of the main controller? It may be just for neatness that the second approach is better, but I'm struggling to see much of a difference between either creating a new method for each category (which communicates with the model and outputs errors/success) or creating a new controller to handle the same functionality. Thanks in advance for any guidance!

  • How to not pass around the container when using IoC in Winforms

    - by L2Type
    I'm new to the world of IoC and having a problem with implementing it in a Winforms application. I have an extremely basic application Winform application that uses MVC, it is one controller that does all the work and a working dialog (obviously with a controller). So I load all my classes in to my IoC container in program.cs and create the main form controller using the container. But this is where I am having problems, I only want to create the working dialog controller when it's used and inside a using statement. At first I passed in the container but I've read this is bad practice and more over the container is a static and I want to unit test this class. So how do you create classes in a unit test friendly way without passing in the container, I was considering the abstract factory pattern but that alone would solve my problem without using the IoC. I'm not using any famous framework, I borrowed a basic one from this blog post http://www.kenegozi.com/Blog/2008/01/17/its-my-turn-to-build-an-ioc-container-in-15-minutes-and-33-lines.aspx How do I do this with IoC? Is this the wrong use for IoC?

  • How to use routing in a ASP MVC website to localize in two languages - But keeping exiting URLs

    - by Anders Pedersen
    We have a couple ASP MVC websites just using the standard VS templates default settings - Working as wanted. But now I want to localize these website ( They are now in Dutch and I will add the English language ) I would like to use routing and not Resource because: 1. Languages will differ in content, numbers of pages, etc. 2. The content is mostly text. I would like the URLs to look some thing like this - www.domain.com/en/Home/Index, www.domain.nl/nl/Home/Index. But the last one should also work with - www.domain.nl/Home/Index - Witch is the exciting URLs. I have implemented Phil Haacks areas ViewEngine from this blogpost - http://haacked.com/archive/2008/11/04/areas-in-aspnetmvc.aspx. But only putting the English website in the areas and keeping the Dutch in old structure. Witch are served as Phils default fallback. But the problem is here that I have to duplicate my controllers for both language's. So I tried the work method described in this tread - http://stackoverflow.com/questions/1712167/asp-net-mvc-localization-route. It works OK with the ?en? and /nl/ but not with the old URLs. When using this code in the global.asax the URL without the culture isn't working. public static void RegisterRoutes(RouteCollection routes) { //routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Default", // Route name "{culture}/{controller}/{action}/{id}", // URL with parameters new { culture = "nl-NL", controller = "Home", action = "Index", id = "" } // Parameter defaults ); routes.MapRoute( "DefaultWitoutCulture", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = "" } // Parameter defaults ); } I properly overlooking some thing simple but I can't get this to work for me. Or are there a better way of doing this?

  • NHibernate: how to handle entity-based validation using session-per-request pattern, without control

    - by Seth Petry-Johnson
    What is the best way to do entity-based validation (each entity class has an IsValid() method that validates its internal members) in ASP.NET MVC, with a "session-per-request" model, where the controller has zero (or limited) knowledge of the ISession? Here's the pattern I'm using: Get an entity by ID, using an IFooRepository that wraps the current NH session. This returns a connected entity instance. Load the entity with potentially invalid data, coming from the form post. Validate the entity by callings its IsValid() method. If valid, call IFooRepository.Save(entity). Otherwise, display error message. The session is currently opened when the request begins and flushed when the request ends. Since my entity is connected to a session, flushing the session attempts to save the changes even if the object is invalid. What's the best way to keep validation logic in the entity class, limit controller knowledge of NH, and avoid saving invalid changes at the end of a request? Option 1: Explicitly evict on validation failure, implicitly flush: if the validation fails, I could manually evict the invalid object in the action method. If successful, I do nothing and the session is automatically flushed. Con: error prone and counter-intuitive ("I didn't call .Save(), why are my invalid changes being saved anyways?") Option 2: Explicitly flush, do nothing by default: By default I can dispose of the session on request end, only flushing if the controller indicates success. I'd probably create a SaveChanges() method in my base controller that sets a flag indicating success, and then query this flag when closing the session at request end. Pro: More intuitive to troubleshoot if dev forgets this step [relative to option 1] Con: I have to call IRepository.Save(entity)' and SaveChanges(). Option 3: Always work with disconnected objects: I could modify my repositories to return disconnected/transient objects, and modify the Repo.Save() method to re-attach them. Pro: Most intuitive, given that controllers don't know about NH. Con: Does this defeat many of the benefits I'd get from NH?

  • Devise routes /:param not working

    - by Jacob Schatz
    Using devise 2.1.0 I am trying to send the new registration page a PricingPlan model. So in my routes I have: devise_scope :user do delete "/logout" => "devise/sessions#destroy" get "/login" => "devise/sessions#new" get "/signup/:plan" => "devise/registrations#new" end And I override the devise registration controller. With this in my routes.rb to make it work: devise_for :users, :controllers => {:registrations => "registrations"} In my actual Registration controller which overrides Devise's controller I have: class RegistrationsController < Devise::RegistrationsController view_paths = "app/views/devise" def new super @plan = PricingPlan.find_by_name(params[:plan]) end So that the default views still go to devise.... In my new view for the registration controller I call this: <h3>You've chosen the <%= @plan.name %> plan.</h3> And I get this error: undefined method `name' for nil:NilClass Also... in my PricingPlan model: class PricingPlan < ActiveRecord::Base has_many :users And in my User model: class User < ActiveRecord::Base belongs_to :pricing_plan I'm rather new at rails.

  • MVC2 Areas not Registering Correctly

    - by Geoffrey
    I believe I have my Areas setup correctly (they were working in MVC1 fine). I followed the guide here: http://odetocode.com/Blogs/scott/archive/2009/10/13/asp-net-mvc2-preview-2-areas-and-routes.aspx I've also used Haacked's Route Debugger. Which shows the correct Area/Controller registration when I run it. However when I try to go to my (AreaName)/(Controller) I get this error: "The resource cannot be found." I believe this indicates there's a problem with the routing, but I'm having trouble debugging this. Where should I set my breakpoints to catch routing errors in MVC2? I'm also using SparkViewEngine compiled against MVC2 references. Could this possibly be causing this error? I've set breakpoints on the controller in the area and it never fires off, I assumed the view engine doesn't kick in until after the controller has been initiated, but I could be wrong. The non-area landing page works fine, and I've stripped my project of all areas except one, to avoid any sort of naming conflicts. Any ideas where I can try to look next?

  • PHP (CodeIgniter) Pass Object Through Session

    - by FranticPedantic
    I am using PHP5 and CodeIgniter and I am trying to implement a single-sign on feature with facebook (although I don't think that facebook is relevant to the question). I am somewhat of a novice with PHP and definitely one with CodeIgniter, so if you think my approach is just completely off telling me that would be helpful too. So here is in short what I am doing: //Controller 1 $this->load->plugin("facebook"); $facebook = new Facebook(array ( 'appId' => $fbconfig['appid'], 'secret' => $fbconfig['secret'], 'cookie' => true, ) ); $fbsession = $facebook->getSession(); //works fine $this->session->set_userdata('facebook', serialize($facebook); Now I would like to grab that facebook object in a different controller. //Controller 2 $facebook = unserialize($this->session->userdata('facebook')); $fbsession = $facebook->getSession(); Produces the error: Call to undefined method getSession. So I look up more about serialization and think that maybe it just doesn't know what the facebook object's attributes are. So I add in a $this->load->plugin('facebook'); To controller 2 as well and I get a "Cannot redeclare class facebook." I am strongly suspecting that I am misunderstanding sessions here. Do I have to somehow tell PHP what kind of object it is? Thanks for the help.

  • Is NSManagedObjectContext autosaved or am I looking at NSFetchedResultsController's cache?

    - by Andreas
    I'm developing an iPhone app where I use a NSFetchedResultsController in the main table view controller. I create it like this in the viewDidload of the main table view controller: NSSortDescriptor *sortDescriptorDate = [[NSSortDescriptor alloc] initWithKey:@"date" ascending:YES]; NSSortDescriptor *sortDescriptorTime = [[NSSortDescriptor alloc] initWithKey:@"start" ascending:YES]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptorDate,sortDescriptorTime, nil]; [fetchRequest setSortDescriptors:sortDescriptors]; [sortDescriptorDate release]; [sortDescriptorTime release]; [sortDescriptors release]; controller = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:context sectionNameKeyPath:@"date" cacheName:nil]; [fetchRequest release]; NSError *error; BOOL success = [controller performFetch:&error]; Then, in a subsequent view, I create a new object on the context: TestObject *testObject = [NSEntityDescription insertNewObjectForEntityForName:@"TestObject" inManagedObjectContext:context]; The TestObject has several related object which I create in the same way and add to the testObject using the provided add...Objects methods. Then, if before saving the context, I press cancel and go back to the main table view, nothing is shown as expected. However, if I restart the app, the object I created on the context shows in the main table view. How come? At first, I thought it was because the NSFetchedResultsController was reading from the cache, but as you can see I set this to nil just to test. Also, [context hasChanges] returns true after I restart. What am I missing here?
