  • iPhone - Cannont access to an IBOutlet (nil valued)

    - by Oliver
    Hello, I have a problem acessing a IBOutlet. I have a NIB inside which there is a tableview, a toolbar and an UILabel (encasulated into a view). The controller (that is the file's owner) is defined as : @interface ChoixPeriodeController : UIViewController <UITableViewDelegate> { IBOutlet UILabel* __periodeInitialeLabel; } @property(nonatomic, retain) UILabel* periodeInitialeLabel; - (void) setSelectedPeriode:(Tache_TypePeriode)typePeriode; In the .m file, this function is called by the parent window to init the Label : - (void) setSelectedPeriode:(Tache_TypePeriode)typePeriode { NSMutableString* tmpString = [NSMutableString string]; [tmpString appendFormat:bla bla bla;....]; self.periodeInitialeLabel.text = tmpString; } Into this function, I can see that self.periodeInitialeLabel is at nil. I can't see why ? Everything is connected into IB... Do you see what can be the problem ?

  • URL Mapping prefix in Grails

    - by Furuno
    Recently, I'm trying to migrating my application from CakePHP to Grails. So far it's been a smooth sailing, everything I can do with CakePHP, I can do it with much less code in Grails. However, I have one question : In CakePHP, there's an URL Prefix feature that enables you to give prefix to a certain action url, for example, if I have these actions in my controller : PostController admin_add admin_edit admin_delete I can simply access it from the URL : mysite/admin/post/add mysite/admin/post/edit/1 mysite/admin/post/delete/2 instead of: mysite/post/admin_add mysite/post/admin_edit/1 mysite/post/admin_delete/2 Is there anyway to do this in Grails, or at least alternative of doing this?

  • How to overload shutdown function?

    - by Michal M
    I am using Kohana (v3) framework but I believe it's not tied to a particular framework. What I have is basically an app with a front-end, where I want to use Kohana's native Kohana::shutdown_handler(), but I also have a part of the - RESTful API - where I don't want colourful and html-encoded exception reporting. I want a plain text reporting. The way I thought it might work is to register another shutdown function in API's controller abstract class constructor, but then I realised register_shutdown_function() works differently to set_exception_handler() and instead of replacing it adds another function to the shutdown procedure. What's worse PHP doesn't allow "unregistering" shutdown functions and that's where my problem lies. What to do, if you want to use another shutdown function instead of one already registered?

  • How do I use a UIView subclass as a container?

    - by dxq
    I'm trying to subclass UIView to create a custom view that is essentially a container. The subclass contains a UILabel and a UIImageView- I can't make either of them show up. Here's an example of what I've been trying: In my main view controller: - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) { ViewClass *myView = [[ViewClass alloc] initWithFrame:CGRectMake(100, 100, 150, 150)]; [view addSubview:myView]; } return self; } In my UIView subclass: - (id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame:frame]) { UILabel *word = [[[UILabel alloc] initWithFrame:[self bounds]] autorelease]; word.text = @"WHY ISN'T THIS SHOWING UP!?"; [self addSubview:word]; } return self; } Can anyone explain what I'm doing wrong? I'm way out of practice with UIKit and Obj-C, and I figure I'm probably missing something obvious.

  • iphone app hangs in AppDelegate (?)

    - by d_CFO
    No nib/IB, so I've inserted "myAppDelegate" in main and deleted the reference to main.xib in info.plist. Debug continues nicely through all five tab controllers; they seem to have gotten properly loaded into the nav controller. In fact, control passes out of the last "}" in applicationDidFinishLaunching. But there was no (visible) response back at [window addSubview:[tabBarController view]]; and [window makeKeyAndVisible]; statements, much less to the loadView within the first tab (program execution never gets there). The last line is, UIApplication _performInitializationWithURL:sourceBundleID:]. I missed a step? I executed a step improperly?

  • MVC Routes - How to get a URL?

    - by Seattle Leonard
    In my current project we have a notification system. When an oject is added to another objects collection, an email is sent to those who are subscibed to the parent object. This happens on the object layer and not in the View or Controller. Here's the problem: Although we can say who created what with what information in the email, we cannot embed links to those objects in the email because in the object layer there is no access to a UrlHelper. To construct a UrlHelper you need a RequestContext, which again does not exist on the object layer. Question: I want to make a helper class to create the url's for me. How can I create an object that will generate these urls without a request context? Is it possible?

  • In Ruby on Rails Routing I Would Like to Use Dash `-` Instead of Underscore `_`

    - by pablitostar
    I would like all the URLs for my web applications to use dash - instead of underscore _ for word separators. I'm surprised about a couple of things really: Google et al. continue to distinguish them. That RoR doesn't have a simple global configuration parameter to map - to _ in the routing. Or does it? I found a few questions here and elsewhere, but the best solution I've seen is to use :as or a named route. That's quite annoying. So I'm thinking of modifying the Rails routing to check for that global config and change - to _ before dispatching to a controller action. But before I do that, I'm hoping someone can save me the trouble! Thanks in advance for any help, or even confirmation that my approach makes sense. I'd submit it back. BTW, I'm currently on 2.3.8, but hope to migrate to 3 soon.

  • Best practice in Rails when editing scaffold made pages

    - by abegbg
    I have a best practice question. I have two classes, company and category. They have a many-to-many relationship. When clicking a category I shall go to a page showing all companies with the chosen category. Pretty straight forward. My question is: Should I list all the companies on the companies/index.html.erb after filtering the companies in the controller? or Should I list all the companies on the categories/show.html.erb page? or Should I do a completely new page, since it doesn't really fit into any of the two above? Do you generally make a new page when your goal doesn't fit the scaffold made pages or do you use them quite freely? I am working/learning alone with rails, so there are a lot of best practice questions popping up all the time. Cheers Carl

  • After a period of time, nslookup still works, but pinging, and an auto-refeshed website, fails.

    - by Mark Hurd
    Contrary to this question this is for a dotted name (gw.localnet.au), and it doesn't happen straight away. Only after some period of time (quite a long time, possibly days). In fact this is for my ADSL router and its internal IP address which I have named within the router itself and in my Windows Server 2003 Domain Controller DNS Service. Specifically, localnet.au is a Active-Directory-backed primary domain. In fact, an ipconfig /flushdns may fix the problem, but only after a while (about the time it took me to type in this question :-) ). That doesn't explain the root cause though...

  • How do I check if an instance has an object to skip displaying the values?

    - by Angela
    I have created a polymorphic association around a model called status. Some contacts will have a status associated with it. Many won't. If I try to call a status when one is not there, I get an error. Right now, even if I haven't created a status for the model, it still runs whatever is in the if-end block. Here's what I am trying, but it's not working: <% if [email protected]? %> <p>Status: <%= @status.find(:last).status %></p> <% end %> In the controller, it is defined below: @status = Contact.find(@contact).statuses By the way, also open to make code more readable and DRY.

  • Need a push in the write direction, to write my first functional test in Rails?

    - by Jason
    Hi, I've read quiet a bit of documentation over the last few days about testing in Rails, I'm sitting down to write my first real test and not 100% sure how to tie what I have learned together to achieve the following functional test (testing a controller) I need to send a GET request to a URL and pass 3 parameters (simple web-service), if the functionality works the keyword "true" is simply returned, otherwise the keyword "false" is returned - its in only value returned & not contained in any , or other tags. The test should assert that if "true" is returned the test is successful. This is probably very simple so apologies for such a non-challenging question. If anyone could point me in the write direction on how I can get started, particularly how I can test the response, I'd be very grateful! Thanks!

  • Storing Object Types in Variable then Initializing

    - by Jon Mattingly
    Is there a way in Objective-C to store an object/class in a variable to be passed to alloc/init somewhere else? For example: UIViewController = foo foo *bar = [[foo alloc] init] I'm trying to create a system to dynamically create navigation buttons in a separate class based on the current view controller. I can pass 'self' to the method, but the variable that results does not allow me to alloc/init. I could always import the .h file directly, but ideally I would like to make reusing the code as simple as possible. Maybe I'm going about this the wrong way?

  • Is there a variable in Rails that equates to the template that is being rendered?

    - by Sean Ahrens
    I can do request.path_parameters['controller'] and request.path_parameters['action'], but is there anything like request.path_parameters['template'] so I can discern which template file (such as index.html.erb) is being rendered? I'm writing a method that automatically sets the body id to the template being rendered, for easy css manipulation: class ApplicationController < ActionController::Base ... after_filter :define_body_selector ... def define_body_selector # sets @body_id to the name of the template that will be rendered # ie. if users/index.html.erb was just rendered, @body_id gets set to "index" @body_id = ??? end ...

  • Spring 3 - Theme with separate JSP

    - by Max
    Hi, I'm trying to rewrite some Spring 1.2 code to Spring 3.0 one. Currently I'm stuck with JSP resolved by URL problem. Application uses separate JSP files with different layouts for serving the same model from the same controller. The JSP is switched using interceptor, that intercepts the url and changes the view. For example: /design_one/mypage.htm -> MyPageController -> /design_one/mypage.jsp /design_two/mypage.htm -> MyPageController -> /design_two/mypage.jsp Is there a way to make same or similar functionality using something better than raw interceptors?

  • How to pass object in :with field for a link_to_remote call

    - by mathee
    I have an object elem that I'd like to pass to the remove_tag_from_cart method. Here is my attempt: -elem = @tags[1] #{elem.name}#{link_to_remote image_tag('x.png'), :url => {:controller => 'questions', :action => 'remove_tag_from_cart'}, :with => {:tag_to_remove => :elem}} The :with clause isn't working correctly. The image does not even show up. If I take out the :with clause, then the link properly shows up and calls the method correctly, but I need the elem object in order to remove it from the cart. Suggestions?

  • Showing an image after loading it from sql database

    - by user330075
    I have a problem showing the image form database in a view Details and a ImageController. Inside the view I have: img src=Url.Action("GetFile","Image", new {id= Model.id}) and in controller: public FileContentResult GetFile(int idl) { //int idl = 32; SqlDataReader rdr; byte[] fileContent = null; ........... return File(,,); } When the view is called, function GetFile it just won't work. But if I cut out the parameter int id1 and I instantiate it as a variable it does work. public FileContentResult GetFile() { int idl = 32; SqlDataReader rdr; byte[] fileContent = null; ........... return File(,,); } Why?

  • RequireHttpsAttribute and Encrypted Request Data

    - by goatshepard
    I have a controller action that is accepting sensitive data. public ActionResult TakeSensitiveData(SensitiveData data){ data.SaveSomewhere(); } To ensure the data is secure I want to be certain requests are made using HTTPS (SSLv3, TLS 1). One of the approaches I've considered using was the RequireHttpsAttribute on my action: [RequireHttps] public ActionResult TakeSensitiveData(SensitiveData data){ data.SaveSomewhere(); } However, upon testing this I fiddler revealed that an HTTP request made to the action is 302 redirected to HTTPS. My question is this: If I've made a request that is 302 redirected to HTTPS haven't I already sent the sensitive data over HTTP before the redirect?

  • CakePHP Routing Alias, no prefix

    I have a dashboard with a series of widgets. Per specification, the widgets need to be buried under a /widgets/ directory. So I have added the following to my routes.php Router::connect('/widget/:controller/:action/*', array()); But I seem to be running into trouble on widgets/links/ and widgets/links/view/1 I am new to CakePHP, but this doesn't seem all that impressive. I have yet to find anything in the Book or by search. So any help is appreciated. Thanks.

  • Rails: Ajax-enabled form without a model object

    - by Caffeine Coma
    I'm new to Rails and having a hard time figuring out how to create a form that submits over Ajax without having a corresponding model object. My use case is a simple form that collects an email address and sends it an email; there's nothing to be persisted, so no model. In cases where I do have a model, I've had success with form_for(@model, remote: true). I can't seem to find the right helper for the case where there is no model. I tried form_tag(named_path, remote: true) and that works, but does not use Ajax. Pointers to an example with an example with a proper controller, .html.erb and routes.rb would be really appreciated.
