  • generateUrl problem

    - by Daniel Hertz
    I am trying to generate a url but I keep getting a strange warning even though it works. I am making an api xml page and I use the following call in the controller: public function executeList(sfWebRequest $request) { $this->users = array(); foreach($this->getRoute()->getObjects() as $user) { $this->users[$this->generateUrl('user_show', $user, true)] = $user->asArray($request->getHost()); } } The user_show route is as follows: # api urls user_show: url: /user/:nickname param: { module: user, action: show } And the xml outputs as follows: <br /> <b>Warning</b>: array_diff_key() [<a href='function.array-diff-key'>function.array-diff-key</a>]: Argument #1 is not an array in <b>/opt/local/lib/php/symfony/routing/sfRoute.class.php</b> on line <b>253</b><br /> <br /> <b>Warning</b>: array_diff_key() [<a href='function.array-diff-key'>function.array-diff-key</a>]: Argument #1 is not an array in <b>/opt/local/lib/php/symfony/routing/sfRoute.class.php</b> on line <b>253</b><br /> <br /> <b>Warning</b>: array_diff_key() [<a href='function.array-diff-key'>function.array-diff-key</a>]: Argument #1 is not an array in <b>/opt/local/lib/php/symfony/routing/sfRoute.class.php</b> on line <b>253</b><br /> <?xml version="1.0" encoding="utf-8"?> <users> <user url="http://krowdd.dev/frontend_dev.php/user/danny"> <name>Danny tz</name> <nickname>danny</nickname> <email>[email protected]</email> <image></image> </user> <user url="http://krowdd.dev/frontend_dev.php/user/adrian"> <name>Adrian Sooian</name> <nickname>adrian</nickname> </user> </users> So it outputs the correct xml but I do not know why it throws thows warning when calling the generateurl method. Thanks!

  • MongoMapper and migrations

    - by Clint Miller
    I'm building a Rails application using MongoDB as the back-end and MongoMapper as the ORM tool. Suppose in version 1, I define the following model: class SomeModel include MongoMapper::Document key :some_key, String end Later in version 2, I realize that I need a new required key on the model. So, in version 2, SomeModel now looks like this: class SomeModel include MongoMapper::Document key :some_key, String key :some_new_key, String, :required => true end How do I migrate all my existing data to include some_new_key? Assume that I know how to set a reasonable default value for all the existing documents. Taking this a step further, suppose that in version 3, I realize that I really don't need some_key at all. So, now the model looks like this class SomeModel include MongoMapper::Document key :some_new_key, String, :required => true end But all the existing records in my database have values set for some_key, and it's just wasting space at this point. How do I reclaim that space? With ActiveRecord, I would have just created migrations to add the initial values of some_new_key (in the version1 - version2 migration) and to delete the values for some_key (in the version2 - version3 migration). What's the appropriate way to do this with MongoDB/MongoMapper? It seems to me that some method of tracking which migrations have been run is still necessary. Does such a thing exist? EDITED: I think people are missing the point of my question. There are times where you want to be able to run a script on a database to change or restructure the data in it. I gave two examples above, one where a new required key was added and one where a key can be removed and space can be reclaimed. How do you manage running these scripts? ActiveRecord migrations give you an easy way to run these scripts and to determine what scripts have already been run and what scripts have not been run. I can obviously write a Mongo script that does any update on the database, but what I'm looking for is a framework like migrations that lets me track which upgrade scripts have already been run.

  • Formatting text in an html table column?

    - by DavidR
    So, I have a table like below. Imagine there are multiple columns, I thought by formatting the <col/> tag I would be able to change the formatting of every <td> in that column. I want to give data in the first column a text-align:center, but it doesn't seem to work. Is there a way to get this to work other than adding a class to every <td>? <table> <col class="column"/> <tr> ... </tr> <tr> ... </tr> <tr> ... </tr> </table>

  • How to do this GQL query in JDO

    - by TheDon
    I have about 50k entities stored in appengine. I am able to look up an individual record via the GQL admin interface with a query like: SELECT * FROM Pet where __key__ = KEY( 'Pet','Fido') But I'm having trouble figuring out how to do a batch version of this via JDO. Right now I have this: PersistenceManager pm = ...; for(Pet pet : pets) { for(String k : getAllAliases(pet)) { keys.add(KeyFactory.createKeyString(Pet.class.getSimpleName(), k)); } } Query q = pm.newQuery("select from " + Pet.class.getName() + " where id == :keys"); List<Pet> petlist = (List<Pet>) q.execute(keys); But though 'Fido' works in the GQL case, it returns nothing when I use that Java + JDO code. What am I doing wrong?

  • Drawing a FrameworkElement within another FrameworkElement

    Hello I have this code: public class VisualCue : FrameworkElement { public List<Indicator> Indicators { get; set; } public VisualCue() { this.Indicators = new List<Indicator>(); } protected override int VisualChildrenCount { get { return this.Indicators.Count; } } protected override Visual GetVisualChild(int index) { return this.Indicators[index]; } } public class Indicator : FrameworkElement { protected override void OnRender(DrawingContext context) { context.DrawEllipse(Brushes.Red, new Pen(Brushes.Black, 2), new Point(0, 0), 10, 10); base.OnRender(context); } } And in XAML: <local:VisualCue x:Name="visualCue"> <local:VisualCue.Indicators> <local:Indicator /> </local:VisualCue.Indicators> </local:VisualCue> But the indicator doesn't get drawn.

    Hi all, Let's say we have such site structure: App_LocalResources       |- A.aspx.resx       |- B.aspx.resx A.aspx B.aspx Now I use HttpContext.GetLocalResourceObject("~/A.aspx") in A.aspx.cs, and it works fine. But if I use HttpContext.GetLocalResourceObject("~/A.aspx") in B.aspx.cs, it throws an exception: The resource class for this page was not found. Please check if the resource file exists and try again. Exception Details: System.InvalidOperationException: The resource class for this page was not found.

  • Django QuerySet filter method returns multiple entries for one record

    - by Yaroslav
    Trying to retrieve blogs (see model description below) that contain entries satisfying some criteria: Blog.objects.filter(entries__title__contains='entry') The results is: [<Blog: blog1>, <Blog: blog1>] The same blog object is retrieved twice because of JOIN performed to filter objects on related model. What is the right syntax for filtering only unique objects?

  • Error accessing a Web Service with SSL

    I have a program that is supposed to send a file to a web service, which requires an SSL connection.

  • Simple Data Caching using Weak References in WCF

    - by Tawani
    Given that I have the following WCF service: class LookUpService { public List<County> GetCounties(string state) { var db = new LookUpRepository(); return db.GetCounties(state); } } class County { public string StateCode{get;set;} public string CountyName{get;set;} public int CountyCode{get;set;} } What will be the most efficient (or best) way to cache a state's counties using weak references (or any other approach) so that we don't hit the database every time we need to look up data. Note that we will not have access to the HttpRuntime (and HttpContext).

  • Letters in base-conversion

    - by tech_geek23
    I have this code written so far and is correct, aside from not using A-F when the value is over 10: public class TenToAny { private int base10; private int newBase; public TenToAny() { } public TenToAny(int ten, int base) { base10 = ten; newBase = base; } public void setNums(int ten, int base) { base10 = ten; newBase = base; } public String getNewNum() { String newNum=""; int orig = base10; //int first = newBase - 1; while(orig > 0) { newNum = orig%newBase + newNum; orig = orig/newBase; } return newNum; } public String toString() { String complete = base10 + " base 10 is " + getNewNum() + " in base " + newBase; return complete; } } Obviously I don't have anything relating to values over 10 converting to A-F as I've never dealt with these before. Any help is appreciated. Here's my runner class: public class Lab09i { public static void main( String args[] ) { TenToAny test = new TenToAny(234, 9); out.println(test); test.setNums(100, 2); out.println(test); test.setNums(10, 2); out.println(test); test.setNums(15, 2); out.println(test); test.setNums(256, 2); out.println(test); test.setNums(100, 8); out.println(test); test.setNums(250, 16); out.println(test); test.setNums(56, 11); out.println(test); test.setNums(89, 5); out.println(test); test.setNums(23, 3); out.println(test); test.setNums(50, 5); out.println(test); test.setNums(55, 6); out.println(test); test.setNums(2500, 6); out.println(test); test.setNums(2500, 13); out.println(test); } } this is what my results should be: 234 base 10 is 280 in base 9 100 base 10 is 1100100 in base 2 10 base 10 is 1010 in base 2 15 base 10 is 1111 in base 2 256 base 10 is 100000000 in base 2 100 base 10 is 144 in base 8 250 base 10 is FA in base 16 56 base 10 is 51 in base 11 89 base 10 is 324 in base 5 23 base 10 is 212 in base 3 50 base 10 is 302 in base 4 55 base 10 is 131 in base 6 2500 base 10 is 9C4 in base 16 2500 base 10 is 11A4 in base 13

  • Memory leak issue with UIImagePickerController

    - by Mustafa
    I'm getting memory leak with UIImagePickerController class. Here's how I'm using it: UIImagePickerController *picker = [[UIImagePickerController alloc] init]; picker.delegate = self; picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; [self presentModalViewController:picker animated:YES]; [picker release]; To remove the picker i call [picker dismissModalViewControllerAnimated:YES]; in didFinishPickingImage and imagePickerControllerDidCancel. -- Instruments show around 160bytes leaking as a result of this instruction: +[UIImagePickerController _loadPhotoLibraryIfNecessary] Apparently this issue has and is disturbing many people, and solution to avoid this problem is to build a singleton class dedicated for picking images from library or capturing using device's build in camera. Anyone want to add something?

  • Blackberry - Exception when sending SMS programmatically

    - by user213199
    Hello all, I am developing a Blackberry application. I am trying to send SMS programmatically to GSM number. I have gone through many queries and answers related to that and finally added the code for that as below. When the code tries to execute sending some text message to the particular mobile number, it doesn't send and throws exception as "blocking operation not permitted on event dispatch thread". So i created a separate background thread where i put the SMS code and running the code now. But still observing the same exception. Could someone please suggest what am i doing wrong (or) how to do that? class DummyFirst extends MainScreen { private Bitmap background; private VerticalFieldManager _container; private VerticalFieldManager mainVerticalManager; private HorizontalFieldManager horizontalFldManager; private BackGroundThread _thread; CustomControl buttonControl1; public DummyFirst() { super(); LabelField appTitle = new LabelField("Dummy App"); setTitle(appTitle); background = Bitmap.getBitmapResource("HomeBack.png"); _container = new VerticalFieldManager(Manager.NO_VERTICAL_SCROLL | Manager.NO_VERTICAL_SCROLLBAR) { protected void paint(Graphics g) { // Instead of these next two lines, draw your bitmap int y = DummyFirst.this.getMainManager() .getVerticalScroll(); g.clear(); g.drawBitmap(0, 0, background.getWidth(), background .getHeight(), background, 0, 0); super.paint(g); } protected void sublayout(int maxWidth, int maxHeight) { int width = background.getWidth(); int height = background.getHeight(); super.sublayout(width, height); setExtent(width, height); } }; mainVerticalManager = new VerticalFieldManager( Manager.NO_VERTICAL_SCROLL | Manager.NO_VERTICAL_SCROLLBAR) { protected void sublayout(int maxWidth, int maxHeight) { int width = background.getWidth(); int height = background.getHeight(); super.sublayout(width, height); setExtent(width, height); } }; HorizontalFieldManager horizontalFldManager = new HorizontalFieldManager(Manager.USE_ALL_WIDTH); buttonControl1 = new CustomControl("Send", ButtonField.CONSUME_CLICK, 83, 15); horizontalFldManager.add(buttonControl1); this.setStatus(horizontalFldManager); FieldListener listner = new FieldListener(); buttonControl1.setChangeListener(listner); _container.add(mainVerticalManager); this.add(_container); } class FieldListener implements FieldChangeListener { public void fieldChanged(Field f, int context) { if (f == buttonControl1) { _thread = new BackGroundThread(); _thread.start(); } } } private class BackGroundThread extends Thread { public BackGroundThread() { /*** initialize parameters in constructor *****/ } public void run() { // UiApplication.getUiApplication().invokeLater(new Runnable() UiApplication.getUiApplication().invokeLater(new Runnable() { public void run() { try { MessageConnection msgConn = (MessageConnection) Connector .open("sms://:0"); Message msg = msgConn .newMessage( MessageConnection.TEXT_MESSAGE); TextMessage txtMsg = (TextMessage) msg; String msgAdr = "sms://+919861348735"; txtMsg.setAddress(msgAdr); txtMsg.setPayloadText("Test Message"); // here exception is thrown msgConn.send(txtMsg); System.out.println("Sending" + " SMS success !!!"); } catch (Exception e) { System.out.println(e.getMessage()); e.printStackTrace(); } } // run }); } } public boolean onClose() { System.out.println("close event called, request to be" + " in the backgroud...."); UiApplication.getUiApplication().requestBackground(); return true; } } I resolved this issue by creating a separate thread and then not using Port etc. Here it is: SMSThread smsthread = new SMSThread("Some message",mobNumber); smsthread.start(); class SMSThread extends Thread { Thread myThread; MessageConnection msgConn; String message; String mobilenumber; public SMSThread( String textMsg, String mobileNumber ) { message = textMsg; mobilenumber = mobileNumber; } public void run() { try { msgConn = (MessageConnection) Connector.open("sms://+"+ mobilenumber); TextMessage text = (TextMessage) msgConn.newMessage(MessageConnection.TEXT_MESSAGE); text.setPayloadText(message); msgConn.send(text); msgConn.close(); } catch (Exception e) { System.out.println("Exception: " + e); } } }

  • Keeping the DI-container usage in the composition root in Silverlight and MVVM

    - by adrian hara
    It's not quite clear to me how I can design so I keep the reference to the DI-container in the composition root for a Silverlight + MVVM application. I have the following simple usage scenario: there's a main view (perhaps a list of items) and an action to open an edit view for one single item. So the main view has to create and show the edit view when the user takes the action (e.g. clicks some button). For this I have the following code: public interface IView { IViewModel ViewModel {get; set;} } Then, for each view that I need to be able to create I have an abstract factory, like so public interface ISomeViewFactory { IView CreateView(); } This factory is then declared a dependency of the "parent" view model, like so: public class SomeParentViewModel { public SomeParentViewModel(ISomeViewFactory viewFactory) { // store it } private void OnSomeUserAction() { IView view = viewFactory.CreateView(); dialogService.ShowDialog(view); } } So all is well until here, no DI-container in sight :). Now comes the implementation of ISomeViewFactory: public class SomeViewFactory : ISomeViewFactory { public IView CreateView() { IView view = new SomeView(); view.ViewModel = ???? } } The "????" part is my problem, because the view model for the view needs to be resolved from the DI-container so it gets its dependencies injected. What I don't know is how I can do this without having a dependency to the DI-container anywhere except the composition root. One possible solution would be to have either a dependency on the view model that gets injected into the factory, like so: public class SomeViewFactory : ISomeViewFactory { public SomeViewFactory(ISomeViewModel viewModel) { // store it } public IView CreateView() { IView view = new SomeView(); view.ViewModel = viewModel; } } While this works, it has the problem that since the whole object graph is wired up "statically" (i.e. the "parent" view model will get an instance of SomeViewFactory, which will get an instance of SomeViewModel, and these will live as long as the "parent" view model lives), the injected view model implementation is stateful and if the user opens the child view twice, the second time the view model will be the same instance and have the state from before. I guess I could work around this with an "Initialize" method or something similar, but it doesn't smell quite right. Another solution might be to wrap the DI-container and have the factories depend on the wrapper, but it'd still be a DI-container "in disguise" there :) Any thoughts on this are greatly appreciated. Also, please forgive any mistakes or rule-breaking, since this is my first post on stackoverflow :) Thanks! ps: my current solution is that the factories know about the DI-container, and it's only them and the composition root that have this dependency.

  • LINQ to Entities Projection of Nested List

    Assuming these objects... class MyClass { int ID {get;set;} string Name {get;set;} List<MyOtherClass> Things {get;set;} } class MyOtherClass { int ID {get;set;} string Value {get;set;} } How do I perform a LINQ to Entities Query, using a projection like below, that will give me a List? This works fine with an IEnumerable (assuming MyClass.Things is an IEnumerable, but I need to use List) MyClass myClass = (from MyClassTable mct in this.Context.MyClassTableSet select new MyClass { ID = mct.ID, Name = mct.Name, Things = (from MyOtherClass moc in mct.Stuff where moc.IsActive select new MyOtherClass { ID = moc.ID, Value = moc.Value }).AsEnumerable() }).FirstOrDefault(); Thanks in advance for the help!

  • WPF TypeConverter ConvertTo not firing

    - by JFoulkes
    Hi, I have a dependency property in a class which I need to be converted to a string. I have added the TypeConverty attribute on the property. The type I am converting is the .net Style class. [TypeConverter(typeof(BulletStyleTypeConverter))] public Style BulletStyle { get { return (Style)GetValue(BulletStyleProperty); } set { this.SetValue(BulletStyleProperty, value); } } When I put the string "Rectangle" in for BulletStyle in xaml it hits the ConvertFrom method in my converter. However, when I use XamlWriter.Save() to serialise this, the property does not appear as an attribute in the string which is produced. I have implemented ConvertTo and put a breakpoint on, which is never hit. I have implemented CanConvertTo and put a breakpoint on, which IS hit and returns true. So i'm stumped as to why ConvertTo never fires.

  • How does this ajax call persist DOM changes in the browser cache?

    - by Greg
    For the purpose of the question I need to create a simple fictitious scenario. I have the following trivial page with one link, call it page A: <a class="red-anchor" onclick="change_color(event);" href="http://mysite.com/b/">B</a> With the associated Javascript function: function change_color(e) { var event = e || window.event; var link = event.target; link.className = "green-anchor"; } And I have the appropriate CSS to make the anchor red or green based on the classname. This is working. That is, when I click the anchor it changes color from red to green, which is briefly visible before the browser loads page B. But if I then use the BACK button to return to page A I get different behavior in different browsers. In Safari, the anchor is still green (desired behavior) In Firefox it reverts to red I imagine that Safari is somehow updating its cached version of the page, whereas Firefox isn't. So my first question is: is there any way to get FF to update the cached page, or is something else happening here? Secondly: I have a different implementation where I use an ajax call. In this I set the class of the anchor using a session variable, something like... <a class="<?php echo $_SESSION["color"]; ?>" ...[snip]... >B</a> And the javascript function makes an additional ajax call that changes the "color" session variable. In this case both Safari and Firefox work as expected. When going back from B to A the color is still green. But I can't for the life of me figure out why it should be different to the non-ajax case. I have tried many different permutations and for it to work on FF the "color" session variable MUST change (i.e. the ajax call itself is not somehow reloading the cache). But on coming BACK, the page is being reloaded from the cache (verified in Firebug), so how is the page even accessing this session variable if it isn't reprocessing the page and running that fragment of php in the anchor? I figure there must be something fundamental here that I am not understanding. Any insight would be much appreciated.

    I'm using Ninject for DI in my asp.net application, so my Global class inherits from NinjectHttpApplication. In my CreateKernel(), I'm creating my custom modules and DI is working fine for me. However, I notice that there is a Logger property in the NinjectHttpApplication class, so I'm trying to use this in Application_Error whenever an exception is not caught. I think I'm creating the nlog module correctly for Ninject, but my logger is always null. Here's my CreateKernel: protected override Ninject.Core.IKernel CreateKernel() { IKernel kernel = new StandardKernel(new NLogModule(), new NinjectRepositoryModule()); return kernel; } But in the following method, Logger is always null. protected void Application_Error(object sender, EventArgs e) { Exception lastException = Server.GetLastError().GetBaseException(); Logger.Error(lastException, "An exception was caught in Global.asax"); } To clarify, Logger is a property on NinjectHttpApplication of type ILogger and has the [Inject] attribute Any idea how to inject correctly into Logger?

  • Displaying Fourier transforms in OpenCV

    - by Simonw
    Hi, I'm just learning to use OpenCV and am having a problem with using DFT. I've done a signal processing class which used MatLab, so I'm trying to go through some of the exercises we did in that class. I'm trying to get and display the FT of an image, so I can mask some of the frequencies. I'd like to be able to see the FT, so I know how big to make the mask, but when I tried, I got an image like this: rather than like one of these Am I forgetting a step somewhere? I'm loading the image, converting its type to CV_32FC1, getting the matrix of it, getting the DFT, and then getting turning the resulting matrix back into an image. I'll post the code I'm using if it will be of any help? Or if someone has a link to an example of displaying the FT? I could only find ones which used it for the convolution. EDIT: Did I get the Phase of the image?

  • Collapse span when input button is hidden

    - by Evan
    I have a style that wraps around an input button, so the button can be styled very creatively. When the button is hidden in .Net, i would like the style to collapse so it renders like its hidden as well. What the style does, as a result of no value in the button or its hidden, is it keeps a small shape. Click to see a demo: http://media.apus.edu/it/evan-testing/button.htm <style> .button { cursor:pointer; text-decoration:none; background:url(button_bg.gif) no-repeat right top; padding-right:10px; display:inline-block; line-height:29px; height:29px; font-size:12px; color:#FFFFFF; font-weight:bold; } span.button { vertical-align: middle; } .button span { background:url(button_bg.gif) no-repeat left top; padding-left:10px; line-height:20px; height:29px; display:inline-block; } .button span span { background:transparent; padding:0; font-size:12px; } .button span input { cursor:pointer; font-weight:bold; background:transparent; border:0; padding-top:.4em; font-size:12px; font-family:verdana; color:#FFFFFF; } .button:hover { background-position:right -39px; } .button:hover span { background-position:left -39px; } .button:active { background-position:right -78px; } .button:active span { background-position:left -78px; } </style> Input button wrapped in a span with no value: <span class="button"><span><input type="button" value=""></span></span> <P> Input button wrapped in a span with a value: <span class="button"><span><input type="button" value="test"></span></span> <P> Span with no data value: <span class="button"><span></span>

  • Clone behaviour - cannot set attribute value for clone?

    - by Dave Jarvis
    This code does not function as expected: // $field contains the name of a subclass of WMSInput. $fieldClone = clone $field; echo $fieldClone->getInputName(); // Method on abstract WMSInput superclass. $fieldClone->setInputName( 'name' ); echo $fieldClone->getInputName(); The WMSInput class: abstract class WMSInput { private $inputName; public function setInputName( $inputName ) { $this->inputName = $inputName; } } There are no PHP errors (error reporting is set to E_ALL). Actual Results email email Expected Results email name Any ideas?

  • django deleting models and overriding delete method

    - by Mike
    I have 2 models class Vhost(models.Model): dns = models.ForeignKey(DNS) user = models.ForeignKey(User) extra = models.TextField() class ApplicationInstalled(models.Model): user = models.ForeignKey(User) added = models.DateTimeField(auto_now_add=True) app = models.ForeignKey(Application) ver = models.ForeignKey(ApplicationVersion) vhost = models.ForeignKey(Vhost) path = models.CharField(max_length=100, default="/") def delete(self): # # remove the files # print "need to remove some files" super(ApplicationInstalled, self).delete() If I do the following >>> vhost = Vhost.objects.get(id=10) >>> vhost.id 10L >>> ApplicationInstalled.objects.filter(vhost=vhost) [<ApplicationInstalled: http://wiki.jy.com/>] >>> vhost.delete() >>> ApplicationInstalled.objects.filter(vhost=vhost) [] As you can see there is an applicationinstalled object linked to vhost but when I delete the vhost, the applicationinstalled object is gone but the print never gets called. Any easy way to do this without iterating through the objects in the vhost delete?

  • Can't define static abstract string property

    - by goombaloon
    I've run into an interesting problem and am looking for some suggestions on how best to handle this... I have an abstract class that contains a static method that accepts a static string that I would like to define as an abstract property. Problem is that C# doesn't doesn't support the following (see the ConfigurationSectionName and Current properties): public abstract class ProviderConfiguration : ConfigurationSection { private const string _defaultProviderPropertyName = "defaultProvider"; private const string _providersPropertyName = "providers"; protected static string ConfigurationSectionName { get; } public static Configuration Current { get { return Configuration)ConfigurationManager.GetSection(ConfigurationSectionName); } } } I suppose one way to handle this would be to make ConfigurationSectionName NOT abstract and then create a new definition of ConfigurationSectionName in the derived classes, but that feels pretty hackish. Any suggestions would be most welcome. Gratias!!!
