• Django: problem with merging querysets after annotation

  - by Björn Lilja

  Hi I have a manager for "Dialog" looking like this: class AnnotationManager(models.Manager): def get_query_set(self): return super(AnnotationManager, self).get_query_set().annotate( num_votes=Count('vote', distinct=True), num_comments=Count('comment', distinct=True), num_commentators = Count('comment__user', distinct=True), ) Votes and Comments has a ForeignKey to Dialog. Comments has a ForeignKey to User. When I do this: dialogs_queryset = Dialog.public.filter(organization=organization) dialogs_popularity = dialogs_queryset.exclude(num_comments=0) | dialogs_queryset.exclude(num_votes=0) ...dialogs_popularity will never returned the combination, but only the dialogs with more than 0 comments, or if I change the order of the OR, the dialogs with more than 0 votes! To me, the expected behavior would be to get the dialogs with more than 0 votes AND the dialogs with more than 0 comments. What am I missing? Or is there a bug in the annotation behavior here?

• Analysis Services with excel as front end - is it possible to get the nicer UI that powerpivot provi

  - by AJM

  I have been looking into PowerPivot and concluded that for "self service BI" and ahoc buidling of cubes it has its uses. In particular I like the enhanced UI that you get from using PowerPivot rather than just using a PivotTable hooked up to an analysis services datasource. However it seems that hooking up PowerPivot to an existing analysis services cube is not a solution for "organisational BI". It is not always desireable to suck millions of rows into excel at once and the interface between PowerPivot and analysis services is very poor in my book. Hence the question is can an existing analysis services solution get the enhanced ui features that power pivot brings, withoout using powerpivot as the design tool? If powerpivot is aimed ad self service/personal BI then it seems bizare that the UI for this is better than for bigger/more costly analysis services solutions.

• Django: way to test what class a generic relation content_object is?

  - by bitbutter

  In my project I have a class, NewsItem. Instances of NewsItem act like a wrapper. They can be associated with either an ArtWork instance, or an Announcement instance. Here's how the NewsItem model looks: class NewsItem(models.Model): content_type = models.ForeignKey(ContentType) object_id = models.PositiveIntegerField() content_object = generic.GenericForeignKey('content_type', 'object_id') date = models.DateTimeField(default=datetime.datetime.now,) class Meta: ordering = ('-date',) def __unicode__(self): return (self.title()) In a template I'm dealing with a NewsItem instance, and would like to output a certain bunch of html it it's 'wrapping' an Artwork instance, and a different bunch of html if it's wrapping an Announcement instance. Could someone explain how I can write a conditional to test for this? My first naive try looked like this: {% if news_item.content_object.type=='Artwork' %}do this{% else %}do that{% endif %}

• NSUndoManager won't undo editing of a NSMutableDictionary

  - by xon1c

  Hi, I'm experiencing problems with the undo operation. The following code won't undo an removeObjectForKey: operation but the redo operation setObject:ForKey: works. - (void) insertIntoDictionary:(NSBezierPath *)thePath { [[[window undoManager] prepareWithInvocationTarget:self] removeFromDictionary:thePath]; if(![[window undoManager] isUndoing]) [[window undoManager] setActionName:@"Save Path"]; NSLog(@"Object id is: %d and Key id is: %d", [currentPath objectAtIndex:0], thePath); [colorsForPaths setObject:[currentPath objectAtIndex:0] forKey:thePath]; } - (void) removeFromDictionary:(NSBezierPath *)thePath { [[[window undoManager] prepareWithInvocationTarget:self] insertIntoDictionary:thePath]; if(![[window undoManager] isUndoing]) [[window undoManager] setActionName:@"Delete Path"]; NSLog(@"Object id is: %d and Key id is: %d", [[colorsForPaths allKeys] objectAtIndex:0], thePath); [colorsForPaths removeObjectForKey:thePath]; } The output on the console looks like: // Before setObject:ForKey: Object id is: 1184384 and Key id is: 1530016 // Before removeObjectForKey: UNDO Object id is: 2413664 and Key id is: 1530016 I don't get why the Object id is different although the Key id remains the same. Is there some special undo/redo handling of NSMutableDictionary objects? thx xonic

• iTunes video black screen until select computer output

  - by Daniel Huckstep

  I don't remember this happening before, but now whenever I play any video in iTunes (podcast video, movie, TV show, iTunes extras stuff but the menus work) it just shows a black screen with the sound playing. If I stop it, select "Computer" in the little output control on the iTunes video control panel that pops up, then play again, it works fine. What the heck? Tried rebooting, updating, with and without external monitor. OSX 10.6.6

• Data sources and NSTableView

  - by lampShade

  I know that table sources need a data source to hold the data that the tableview will display. Lets' say that I'm going to make my AppController be the data source of my tableview and that I make the connection in interface builder. My question is since my actual data is going to be stored in an array,let's call it myArray, when I set the data source in code should I do this [tableView setDataSource:myArray]; or this [tableView setDataSource:self]; I'm confused about this. setting the data source with the keyword "self" would set it to the AppController if I'm not mistaken.

• Editing a UIViewController from another class.

  - by Guy

  I am trying to programmatically change the user interface of a UIViewController from another NSObject class. The problem is that I am unsure of how to access the UIViewController's view from the NSObject class. So for example, in my NSObject class, I say something like: self.view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)]; self.view.backgroundColor = [UIColor yellowColor]; but I keep getting errors saying "Request for member "view" in something not a strut or union." Is there something I need to allow my NSObject class to see my UIViewController? Thanks!

• How to execute statements in order in objective c

  - by Vu Tu?n Anh

  When i tap on my button, my function was called [myBtn addTarget:self action:@selector(myFunction) forControlEvents:UIControlEventTouchUpInside]; In my function, a collection of complex statement will be executed and take a litte bit time to run, so i want to show Loading (UIActivityIndicatorView) as the following: -(void) addTradeAction { //Show Loading [SharedAppDelegate showLoading]; //disable user interaction self.view.userInteractionEnabled = NO; //execute call webservice in here - may be take 10s //Hide Loading [ShareAppDelegate hideLoading]; } When tap on myBtn (my Button) - after 3s or 4s, [ShareAppDelegate showLoading] was called. It is unusual when i use [ShareAppDelegate showLoading] on other Function, - it work very nice, i mean all the statement be executed in order. All i want, when i tap on My Button, Loading will be called immediatelly. Tks in advance

• WebKitErrorDomain error 101

  - by Nam Young-jun

  The following code produces and error of: WebKitErrorDomain error 101 code: -(Void) searchBarSearchButtonClicked: (UISearchBar *) activeSearchBar { NSString * query = [searchBar.text stringByReplacingOccurrencesOfString: @ "" withString: @ "+"]; NSURL * url = [NSURL URLWithString: [NSString stringWithFormat: @ "http://http://www.google.com/search?q =%, query]]; NSURLRequest * requestObj = [NSURLRequest requestWithURL: url]; [Home loadRequest: requestObj]; } -(Void) loadView { [Super loadView]; CGRect bounds = [[UIScreen mainScreen] applicationFrame]; searchBar = [[UISearchBar alloc] initWithFrame: CGRectMake (0.0, 0.0, bounds.size.width, 48.0)]; searchBar.delegate = self; [Self.view addSubview: searchBar]; } I don't speak english and rely on a translator. Because of the language issue could this be a keyboard problem, or an encoding problem?

• Is there a better IIS 7 bindings dialog?

  - by uhpl1

  Some of my sites in IIS have 20-30 bindings and the bindings dialog box in IIS 7 is 4 lines, which makes editing bindings a real pain. Are there any replacements/upgrades for the dialog specifically? I realize behind the scenes it is just updating an XML file, but I would prefer not to directly edit the XML file or start writing a separate management application, if possible.

• Resizing Tab Bar Controller Views (iPhone dev)

  - by damiandawber

  Hello, I have an application set up where the window contains a tab bar controller and one of the tabs loads a NIB called 'ShowCaseView.xib': this file is owned by a custom ShowcaseViewController class. In the ShowcaseViewcontroller class I have added a UIScrollView object, like so: imageScrollView = [[UIScrollView alloc] initWithFrame:[[self view] bounds]]; [[self view] addSubview:imageScrollView]; The issue I am having is that this UIScrollView object extends beneath my tab bar controller. So I have had to reduce its insets manually: #define TAB_BAR_HEIGHT 48 . . UIEdgeInsets edgeInsets = UIEdgeInsetsMake(0, 0, TAB_BAR_HEIGHT, 0); [imageScrollView setScrollIndicatorInsets:edgeInsets]; So, Is it common to have to manually deduct the tab bar height from a view (whether this be by reducing the size of subviews or the View NIB in inspector)? Is there a way that I can tell a NIB's view loaded from a tab bar to resize itself automatically to NOT sit behind the tab bar? Cheers

• Concurrent NFS access

  - by Kristian

  Similar to Concurrent FTP access. How is concurrent file access handled for NFS? Say that one client is updating/overwriting a file on a NFS server, and a process on the server is reading that same file directly from the file system at the same time. Is there some sort of atomic handling of file read/write in NFS/Linux or do I have to work with tmp files to ensure data consistency? I'm worried that the process reading the file will get corrupt data.

• Twisted chainDeferred not working as expected

  - by Martin Gergov

  I have a problem figuring out a somewhat simple twisted python code. From what I have red in the docs, the code here should work without Unhandled Error. I get this: HELLO! HANDLED! HANDLED 2!

• Remove a toolbar when pushing a new view

  - by nevan

  In the iPhone maps app there's a toolbar at the bottom of the map view (it contains the Search/Directions segment control and others). When moving from the map view by clicking on a callout, the toolbar slides out with the map view, leaving the next view (a table controller) with no toolbar. I've tried to do the same thing with [self.navigationController setToolbarHidden:YES animated:YES] in the second view controller, but this gives a strange toolbar sliding down animation, while the map view is sliding to the left. Using [self.navigationController setToolbarHidden:YES] in viewDidLoad:animated also causes a bad effect (it makes the toolbar disappear the moment the push animation starts, leaving an ugly white space). I'm assuming the answer to this is to use a nib file, but I'd prefer to do it programatically (if possible). How can I get the toolbar to "stick" to the map view and slide out with it when I push a new view controller? Thanks.

• iphone instance / class method issue

  - by user290031

  Hey All, Okay, so I have a viewController method that has some elements created with interface builder and some I coded myself. I created a view in the IB...lets call it viewOne. I created a loop that creates buttons (through code) and places them on a separate view (viewTwo). This is done in a class method. However, I want the view I made to be opened everytime one of the buttons is clicked. So I did: [button addTarget:self action:@selector(woogoo:) forControlEvents:UIControlEventTouchUpInside]; The woogoo class does the following: +(void) woogoo:(id)sender { //back button [self.view addSubview:viewOne] } However, the program crashes when a button is clicked. I did try making woogoo an instance method but it also crashes in this case too. All I want to do is show viewOne when a button is clicked. Any ideas what I can do?

• Why is my UIViewController initializer never called?

  - by mystify

  I made a view-based project from a fresh template. There's a UIViewController which is created with an XIB. In the implementation I uncommented that and added an NSLog. But this is never called: // The designated initializer. Override to perform setup that is required before the view is loaded. - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { if ((self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil])) { // Custom initialization NSLog(@"nib"); } return self; } since that is initialized from a nib / xib, that should be called for sure, right? however, it doesn't. I do get an NSLog message when I put that in viewDidLoad.

• Quering distinct values throught related model

  - by matheus.emm

  Hi! I have a simple one-to-many (models.ForeignKey) relationship between two of my model classes: class TeacherAssignment(models.Model): # ... some fields year = models.CharField(max_length=4) class LessonPlan(models.Model): teacher_assignment = models.ForeignKey(TeacherAssignment) # ... other fields I'd like to query my database to get the set of distinct years of TeacherAssignments related to at least one LessonPlan. I'm able to get this set using Django query API if I ignore the relation to LessonPlan: class TeacherAssignment(models.Model): # ... model's fields def get_years(self): year_values = self.objects.all().values_list('year').distinct().order_by('-year') return [yv[0] for yv in year_values if len(yv[0]) == 4] Unfortunately I don't know how to express the condition that the TeacherAssignment must be related to at least one LessonPlan. Any ideas how I'd be able to write the query? Thanks in advance.

• iPhone check for a constant at runtime in universal app

  - by joshue

  I'm making a universal iPad/iPhone app which can use the iPad's VGA out connector to mirror the content of the app on an external screen. However, the iPhone does not have this functionality. given the following code, [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(screenInfoNotificationReceieved:) name:UIScreenDidConnectNotification object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(screenInfoNotificationReceieved:) name:UIScreenDidDisconnectNotification object:nil]; I get this error on the phone at launch (works fine in ipad) "dyld: Symbol not found: _UIScreenDidConnectNotification" presumably because UIScreenDidConnectNotification doesnt' exist yet in 3.13. How do I check for this at runtime?

• NSAutoreleasePool carrying across methods?

  - by Tim

  I'm building an iPhone application where I detach some threads to do long-running work in the background so as not to hang the UI. I understand that threads need NSAutoreleasePool instances for memory management. What I'm not sure about is if the threaded method calls another method - does that method also need an NSAutoreleasePool? Example code: - (void)primaryMethod { [self performSelectorInBackground:@selector(threadedMethod) withObject:nil]; } - (void)threadedMethod { NSAutoreleasePool *aPool = [[NSAutoreleasePool alloc] init]; // Some code here [self anotherMethod]; // Maybe more code here [aPool drain]; } - (void)anotherMethod { // More code here } The reason I ask is I'm receiving errors that objects are being autoreleased with no pool in place, and are "just leaking." I've seen other questions where people didn't have autorelease pools in place at all, and I understand why an autorelease pool is needed. I'm specifically interested in finding out whether an autorelease pool created in (in this example) threadedMethod applies to objects created in anotherMethod.

• Cheap windows driver signing for 64 bit Windows 7

  - by kayahr

  I need to install the libusb-win32 driver on Windows 7 64 bit machines. This driver is open source so it is not digitally signed so I want to do this my self but I wonder if this can be done WITHOUT paying lot of money. Is it possible to use a certificate which is NOT signed by Verisign or GlobalSign? Maybe self-signed or by using StartSSL instead? And if yes, how do I do it? According to this howto I have to use a "cross-certificate" (And there are only six available on the Microsoft list and most of them are for CAs which are no longer active) I don't care if the user is confronted with a warning message. I can even accept if the user has to install a special CA certificate first. I only require that the driver runs without manually disabling the signature check on each windows startup.
