  • Django forms: how to dynamically create ModelChoiceField labels

    - by Henri
    I would like to create dynamic labels for a forms.ModelChoiceField and I'm wondering how to do that. I have the following form class: class ProfileForm(forms.ModelForm): def __init__(self, data=None, ..., language_code='en', family_name_label='Family name', horoscope_label='Horoscope type', *args, **kwargs): super(ProfileForm, self).__init__(data, *args, **kwargs) self.fields['family_name'].label = family_name_label . . self.fields['horoscope'].label = horoscope_label self.fields['horoscope'].queryset = Horoscope.objects.all() class Meta: model = Profile family_name = forms.CharField(widget=forms.TextInput(attrs={'size':'80', 'class': 'contact_form'})) . . horoscope = forms.ModelChoiceField(queryset = Horoscope.objects.none(), widget=forms.RadioSelect(), empty_label=None) The default labels are defined by the unicode function specified in the Profile definition. However the labels for the radio buttons created by the ModelChoiceField need to be created dynamically. First I thought I could simply override ModelChoiceField as described in the Django documentation. But that creates static labels. It allows you to define any label but once the choice is made, that choice is fixed. So I think I need to adapt add something to init like: class ProfileForm(forms.ModelForm): def __init__(self, data=None, ..., language_code='en', family_name_label='Family name', horoscope_label='Horoscope type', *args, **kwargs): super(ProfileForm, self).__init__(data, *args, **kwargs) self.fields['family_name'].label = family_name_label . . self.fields['horoscope'].label = horoscope_label self.fields['horoscope'].queryset = Horoscope.objects.all() self.fields['horoscope'].<WHAT>??? = ??? Anyone having any idea how to handle this? Any help would be appreciated very much.

  • Using LinqSql, stored procedure returns datatype image problem

    - by Elias
    Hello! I´ve got a problem when using LINQ to execute a stored procedure and return its values. One of the column that the stored procedure returns is of datatype image and contains a pdf in binary form.(this because the database is deployed on sql server 2000, otherwised i would choose a blob) When including the stored procedure in my linq class its generates that my pdf columns is datatype int in the designer class. I´ve work around the problem and manually changed the datatype in representation of the stored procedure in the designer class. But when adding/removing items in the linq class the designer file re-generates and my changes are lost. Are there any better solution for my problem??

  • How does Perl's lib pragma work?

    - by Tyug
    I use use lib "./DIR" to grab a library from a folder elsewhere. However, it doesn't seem to work on my server, but it works fine on my local desktop. Any particular reasons? And one more question, does use lib get propagated within several modules? Two situations: Say I make a base class that requires a few libraries, but I know that it needs to be extended and the extended class will need to use another library. Can I put the use lib command in the base class? or will I need to put it in every extending class? Finally, can I just have a use package where package contains a bunch of use lib, will it propagate the use lib statements over to my current module? <-- I don't think so, but asking anyways

  • Jboss logging issue - pl check this

    - by balaji
    I’m Working as deployer and server administrator. We use Jboss 4.0x AS to deploy our applications. The issue I'm facing is, Whenever we redeploy/restart the server, server.log is getting created but after sometime the logging goes off. Yes it is not at all updating the server.log file. Due to this, we could not trace the other critical issues we have. Actually we have two separate nodes and we do deploy/restarting the server separately on two nodes. We are facing the issue in both of our test and production environment. I could not trace out where exactly the issue is. Could you please help me in resolving the issue? If we have any other issues, we can check the log files. If log itself is not getting updated/logged, how can we move further in analyzing the issues without the recent/updated logs? Below are the logs found in the stdout.log: 18:55:50,303 INFO [Server] Core system initialized 18:55:52,296 INFO [WebService] Using RMI server codebase: http://kl121tez.is.klmcorp.net:8083/ 18:55:52,313 INFO [Log4jService$URLWatchTimerTask] Configuring from URL: resource:log4j.xml 18:55:52,860 ERROR [STDERR] LOG0026E The Log Manager cannot create the object AmasRBPFTraceLogger without a class name. 18:55:52,860 ERROR [STDERR] LOG0026E The Log Manager cannot create the object AmasRBPFMessageLogger without a class name. 18:55:54,273 ERROR [STDERR] LOG0026E The Log Manager cannot create the object AmasCacheTraceLogger without a class name. 18:55:54,274 ERROR [STDERR] LOG0026E The Log Manager cannot create the object AmasCacheMessageLogger without a class name. 18:55:54,334 ERROR [STDERR] LOG0026E The Log Manager cannot create the object JACCTraceLogger without a class name. 18:55:54,334 ERROR [STDERR] LOG0026E The Log Manager cannot create the object JACCMessageLogger without a class name. 18:55:56,059 INFO [ServiceEndpointManager] WebServices: jbossws-1.0.3.SP1 (date=200609291417) 18:55:56,635 INFO [Embedded] Catalina naming disabled 18:55:56,671 INFO [ClusterRuleSetFactory] Unable to find a cluster rule set in the classpath.

  • How can I catch a "catchable fatal error" on PHP type hinting?

    - by Ho
    Hello, I am trying to implement Type Hinting of PHP5 on one of my class, class ClassA { public function method_a (ClassB $b) {} } class ClassB {} class ClassWrong{} Correct usage: $a = new ClassA; $a->method_a(new ClassB); producing error: $a = new ClassA; $a->method_a(new ClassWrong); Catchable fatal error: Argument 1 passed to ClassA::method_a() must be an instance of ClassB, instance of ClassWrong given... May I know if it is possible to catch that error(since it says "catchable")? and if yes, how? Thank you.

  • Eclipse Javadoc tooltip help doesn't show classes' supertypes and interfaces

    - by Pooria
    I'm talking about the tooltip that pops up when you hover your mouse over a class in your source (which also helps with intellisense and auto completion), which describes what a class/method/etc does. I find it very annoying that it doesn't show what superclass the class (being described) extends or what interfaces it implements. Is there a way to make eclipse show the additional information?

  • Sorting of table column by string length not working as intended when done in IB via cocoa - binding

    - by Miraaj
    Hi all, I made a sample application displaying list of employees with their salaries over NSTableView using NSArrayController. Basic functionality is working as intended. Also sorting is working fine when Selector - compare or caseInsensitiveCompare is assigned in attribute pane for table column- employeeName. Problem occurs when I try to sort it by string length by setting selector in IB as - length, for the table column - employeeName. It does sorting by string length but does it inappropriately. It is doing sorting on alternate clicks ie. on first click it sorts the content in table in descending order by length. Then on second click it does not arrange contents in ascending order by length but sets arrow on top as in ascending. Then on third click it arranges contents in ascending order by length but sets arrow on top of table column as in descending and so on... Can anyone suggest if I am wrong somewhere? Thanks, Miraaj

  • memcache is not storing data accross requests

    - by morpheous
    I am new to using memcache, so I may be doing something wrong. I have written a wrapper class around memcache. The wrapper class has only static methods, so is a quasi singleton. The class looks something like this: class myCache { private static $memcache = null; private static $initialized = false; public static function init() { if (self::$initialized) return; self::$memcache = new Memcache(); if (self::configure()) //connects to daemon { self::store('foo', 'bar'); } else throw ConnectionError('I barfed'); } public static function store($key, $data, $flag=MEMCACHE_COMPRESSED, $timeout=86400) { if (self::$memcache->get($key)!== false) return self::$memcache->replace($key, $data, $flag, $timeout); return self::$memcache->set($key, $data, $flag, $timeout); } public static function fetch($key) { return self::$memcache->get($key); } } //in my index.php file, I use the class like this require_once('myCache.php'); myCache::init(); echo 'Stored value is: '. myCache::fetch('foo'); The problem is that the myCache::init() method is being executed in full everytime a page is requested. I then remembered that static variables do not maintain state accross page requests. So I decided instead, to store the flag that indicates whether the server contains the start up data (for our purposes, the variable 'foo', with value 'bar') in memcache itself. Once the status flag is stored in memcache itself, It solves the problem of the initialisation data being loaded for every page request (which quite frankly, defeats the purpose of memcache). However, having solved that problem, when I come to fetch the data in memcache, it is empty. I dont understand whats going on. Can anyone clarify how I can store my data once and retrieve it accross page requests? BTW, (just to clarify), the get/set is working correctly, and if I allow memcache to load the initialisation data for each page request, (which is silly), then the data is available in memcache.

  • ASP.NET MVC CRUD PartialView Popup Issue

    - by Smiley Face
    I am creating an MVC website which makes use of Partial Views on Popups to handle all my CRUD transactions. Please note that my application can already handle these CRUD operations perfectly (LINQ-To-Entity). However, I have a problem with my popup forms. Below is the code from my _Add.cshtml: @model MyStore.Models.MyModels.ProductsModel @{ Layout = null; } @using (Ajax.BeginForm("_Add", "Products", new AjaxOptions { InsertionMode = InsertionMode.Replace, HttpMethod = "POST", OnSuccess = "addSuccess" }, new { @id = "addForm" })) { @Html.ValidationSummary(true) <div id="add-message" class="error invisible"></div> <fieldset> <legend>Products</legend> @Html.HiddenFor(m => Model.ProductCode) <div class="editor-label"> @Html.LabelFor(model => model.ProductName) </div> <div class="editor-field"> @Html.EditorFor(model => model.ProductName) @Html.ValidationMessageFor(model => model.ProductName) </div> <div class="editor-label"> @Html.LabelFor(model => model.Price) </div> <div class="editor-field"> @Html.TextBoxFor(model => model.Price) @Html.ValidationMessageFor(model => model.Price) </div> </fieldset> } Below is the code from my Controller: [HttpGet] public ActionResult _Add(string productCode) { ProductsModel model = newProductsModel(); model.ProductCode = ProductCode ; return PartialView(model); } [HttpPost] public JsonResult _Add(ProductsModel model) { if (ModelState.IsValid) { ProductsManager prod = new ProductsManager(); Products pa = new Products(); pa.ProductCode = model.ProductCode; pa.ProductName = model.ProductName; pa.Price = model.Price; prod.AddProduct(pa); return Json(HelperClass.SuccessResponse(pa), JsonRequestBehavior.AllowGet); } else { return Json(HelperClass.ErrorResponse("Please review your form"), JsonRequestBehavior.DenyGet); } } Please note that the _Add.cshtml is a partial view which is being rendered through a Popup.js which I found on the internet. It is rendered through this code: @Html.ActionLink("[Add Product]", "_Add", new { ProductCode = @ViewData["ProductCode"] }, new { @class = "editLink" }) This works okay. I mean it adds product to my database. But my problem is upon clicking the Proceed button, I get this pop-up download dialog from the page: Can somebody please help me with this? I have a hunch it's because of the HttpMethod i'm using (POST, PUT, GET, DELETE) but i'm not really sure which one is right to use or if it really is the problem in the first place. Any help would be greatly appreciated! PS. Sorry for the long post.

  • jQuery internals: Organization of the jQuery Object

    - by sonofdelphi
    I was going through the source code of jQuery. I'm having trouble understanding the wrapping strategy for the jQuery object. (function( window, undefined ) { // Define a local copy of jQuery var jQuery = function( selector, context ) { // The jQuery object is actually just the init constructor 'enhanced' return new jQuery.fn.init( selector, context ); }, .... .... .... // Expose jQuery to the global object window.jQuery = window.$ = jQuery; })(window); Specifically, what I'm not able to understand stems from the first line. What is the outermost unnamed container function? Why is it required? Why is the container function anonymous? What is the need for the outermost '(' parantheses ?

  • Simplest PHP Routing framework .. ?

    - by David
    I'm looking for the simplest implementation of a routing framework in PHP, in a typical PHP environment (Running on Apache, or maybe nginx) .. It's the implementation itself I'm mostly interested in, and how you'd accomplish it. I'm thinking it should handle URL's, with the minimal rewriting possible, (is it really a good idea, to have the same entrypoint for all dynamic requests?!), and it should not mess with the querystring, so I should still be able to fetch GET params with $_GET['var'] as you'd usually do.. So far I have only come across .htaccess solutions that puts everything through an index.php, which is sort of okay. Not sure if there are other ways of doing it. How would you "attach" what URL's fit to what controllers, and the relation between them? I've seen different styles. One huge array, with regular expressions and other stuff to contain the mapping. The one I think I like the best is where each controller declares what map it has, and thereby, you won't have one huge "global" map, but a lot of small ones, each neatly separated. So you'd have something like: class Root { public $map = array( 'startpage' => 'ControllerStartPage' ); } class ControllerStartPage { public $map = array( 'welcome' => 'WelcomeControllerPage' ); } // Etc ... Where: 'http://myapp/' // maps to the Root class 'http://myapp/startpage' // maps to the ControllerStartPage class 'http://myapp/startpage/welcome' // maps to the WelcomeControllerPage class 'http://myapp/startpage/?hello=world' // Should of course have $_GET['hello'] == 'world' What do you think? Do you use anything yourself, or have any ideas? I'm not interested in huge frameworks already solving this problem, but the smallest possible implementation you could think of. I'm having a hard time coming up with a solution satisfying enough, for my own taste. There must be something pleasing out there that handles a sane bootstrapping process of a PHP application without trying to pull a big magic hat over your head, and force you to use "their way", or the highway! ;)

  • How to combine multiple uiBinder-based widgets?

    - by jprusakova
    I need to insert a [number of] uiBinder-based widgets into another one, at a particular spot. The inserted widget has a somewhat complicated layout, so I am trying to define it in HTML. referencePanel.add(...) fails with NoSuchElement exception. reference.getElement().toSource returns "undefined". Any suggestions on how to do that? public class AppUIDemo extends Composite { @UiTemplate("AppUIDemo.ui.xml") interface AppUIDemoUiBinder extends UiBinder<Widget, AppUIDemo> { } @UiTemplate("ReferenceUI.ui.xml") interface ReferenceUIUiBinder extends UiBinder<Widget, ReferenceUI> { } private static AppUIDemoUiBinder uiBinder = GWT .create(AppUIDemoUiBinder.class); private static ReferenceUIUiBinder refUIBinder = GWT .create(ReferenceUIUiBinder.class); @UiField HTMLPanel referencePanel; public AppUIDemo() { initWidget(uiBinder.createAndBindUi(this)); ReferenceUI reference = new ReferenceUI(refUIBinder); referencePanel.add(reference, reference.getElement().getId()); } } public class ReferenceUI extends Composite { interface ReferenceUIUiBinder extends UiBinder<Widget,ReferenceUI> { } private static ReferenceUIUiBinder uiBinder = GWT .create(ReferenceUIUiBinder.class); public ReferenceUI() { initWidget(uiBinder.createAndBindUi(this)); } public CreditReferenceUI(final UiBinder<Widget, CreditReferenceUI> binder) { initWidget(binder.createAndBindUi(this)); } }

  • Is this a bug or something I am doing wrong?

    - by Brian Gideon
    I cannot imagine how this is anything other than a bug, but since I do not currently have a login for the MS Connect website I will ask here first. I have Visual Studio 2008 SP 1 with all post SP1 hotfixes I could find relating to the crash installed. Can you reproduce the following crash? 1) Create a new "WPF Application" project using VB as the language (though I suspect it will happen in C# as well). 2) Enter the following code in the Window1.xaml.vb file. Friend MustInherit Class A End Class Friend MustInherit Class A(Of T) Inherits A End Class 3) Add a namespace declaration the Window1.xaml file so that it looks like the following. <Window x:Class="Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:WpfApplication1" Title="Window1" Height="300" Width="300"> <Grid> </Grid> </Window> 4) Now attempt to edit the xaml file by opening a new xml tag via the < character. 5) CRASH! Edit: Microsoft has confirmed this bug. The issue still exists in VS2010 beta 2, but will be fixed in the next release.

  • Adding classes to all form widgets in symfony

    - by rlahay
    Hi everyone, I am trying to find a better way to assign classes to form elements in symfony. Currently, I can't seem to get away from assigning each one manually. ie: $this->widgetSchema['title']->setAttribute("class","fieldInput"); $this->widgetSchema['tag_line']->setAttribute("class","fieldInput"); $this->widgetSchema['description']->setAttribute("class","fieldInput"); // etc Things I tried without success 1) looping through $this-widgetSchema, treating it as an array and setting attributes to each key 2) $this-widgetSchema-setAttribute() but this only applied the class to the label that was generated, not the form element There must be a way to hit all the fields without specifically directing them? Can anyone point me in the right direction?

  • Can't access annotation property of subclassed uibutton - editted

    - by Tzur Gazit
    Below is my original question. I kept investigating and found out that the type of the button I allocate is of type UIButton instead of the subclassed type CustomButton. the capture below is the allocation of the button and connection to target. I break immediately after the allocation and check the button type (po rightButton at the debugger console). It's turned out tht the type is UIButton instead of CustomButton. CustomButton* rightButton = [CustomButton buttonWithType:UIButtonTypeDetailDisclosure]; [rightButton addTarget:self action:@selector(showDetails:) forControlEvents:UIControlEventTouchUpInside]; I have a mapView to which I add annotations. The pin's callout have a button (rightCalloutAccessoryView). In order to be able to display various information when the button is pushed, i've subclassed uibutton and added a class called "Annotation". @interface CustomButton : UIButton { NSIndexPath *indexPath; Annotation *mAnnotation; } @property (nonatomic, retain) NSIndexPath *indexPath; @property (nonatomic, copy) Annotation *mAnnotation; - (id) setAnnotation2:(Annotation *)annotation; @end Here is "Annotation": @interface Annotation : NSObject <MKAnnotation> { CLLocationCoordinate2D coordinate; NSString *mPhotoID; NSString *mPhotoUrl; NSString *mPhotoName; NSString *mOwner; NSString *mAddress; } @property (nonatomic, assign) CLLocationCoordinate2D coordinate; @property (nonatomic, copy) NSString *mPhotoID; @property (nonatomic, copy) NSString *mPhotoUrl; @property (nonatomic, copy) NSString *mPhotoName; @property (nonatomic, copy) NSString *mOwner; @property (nonatomic, copy) NSString *mAddress; - (id) initWithCoordinates:(CLLocationCoordinate2D)coordinate; - (id) setPhotoId:(NSString *)id url:(NSString *)url owner:(NSString *)owner address:(NSString *)address andName:(NSString *)name; @end I want to set the annotation property of the uibutton at - (MKAnnotationView *)mapView:(MKMapView *)pMapView viewForAnnotation:(id )annotation, in order to refer to it at the button push handler (-(IBAction) showDetails:(id)sender). The problem is that I can't set the annotation property of the button. I get the following message at run time: 2010-04-27 08:15:11.781 HotLocations[487:207] *** -[UIButton setMAnnotation:]: unrecognized selector sent to instance 0x5063400 2010-04-27 08:15:11.781 HotLocations[487:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UIButton setMAnnotation:]: unrecognized selector sent to instance 0x5063400' 2010-04-27 08:15:11.781 HotLocations[487:207] Stack: ( 32080987, 2472563977, 32462907, 32032374, 31884994, 55885, 30695992, 30679095, 30662137, 30514190, 30553882, 30481385, 30479684, 30496027, 30588515, 63333386, 31865536, 31861832, 40171029, 40171226, 2846639 ) I appreciate the help.

  • Problem with returning values from a helper method in Rails

    - by True Soft
    I want to print some objects in a table having 2 rows per object, like this: <tr class="title"> <td>Name</td><td>Price</td> </tr> <tr class="content"> <td>Content</td><td>123</td> </tr> I wrote a helper method in products_helper.rb, based on the answer of this question. def write_products(products) products.map { |product| content_tag :tr, :class => "title" do content_tag :td do link_to h(product.name), product, :title=>product.name end content_tag :td do product.price end end content_tag :tr, :class => "content" do content_tag :td, h(product.content) content_tag :td, product.count end }.join end But this does not work as expected. It only returns the last node - the last <td>123</td> What should I do to make it work?

  • Using pointers, references, handles to generic datatypes, as generic and flexible as possible

    - by Patrick
    In my application I have lots of different data types, e.g. Car, Bicycle, Person, ... (they're actually other data types, but this is just for the example). Since I also have quite some 'generic' code in my application, and the application was originally written in C, pointers to Car, Bicycle, Person, ... are often passed as void-pointers to these generic modules, together with an identification of the type, like this: Car myCar; ShowNiceDialog ((void *)&myCar, DATATYPE_CAR); The 'ShowNiceDialog' method now uses meta-information (functions that map DATATYPE_CAR to interfaces to get the actual data out of Car) to get information of the car, based on the given data type. That way, the generic logic only has to be written once, and not every time again for every new data type. Of course, in C++ you could make this much easier by using a common root class, like this class RootClass { public: string getName() const = 0; }; class Car : public RootClass { ... }; void ShowNiceDialog (RootClass *root); The problem is that in some cases, we don't want to store the data type in a class, but in a totally different format to save memory. In some cases we have hundreds of millions of instances that we need to manage in the application, and we don't want to make a full class for every instance. Suppose we have a data type with 2 characteristics: A quantity (double, 8 bytes) A boolean (1 byte) Although we only need 9 bytes to store this information, putting it in a class means that we need at least 16 bytes (because of the padding), and with the v-pointer we possibly even need 24 bytes. For hundreds of millions of instances, every byte counts (I have a 64-bit variant of the application and in some cases it needs 6 GB of memory). The void-pointer approach has the advantage that we can almost encode anything in a void-pointer and decide how to use it if we want information from it (use it as a real pointer, as an index, ...), but at the cost of type-safety. Templated solutions don't help since the generic logic forms quite a big part of the application, and we don't want to templatize all this. Additionally, the data model can be extended at run time, which also means that templates won't help. Are there better (and type-safer) ways to handle this than a void-pointer? Any references to frameworks, whitepapers, research material regarding this?
