  • Ordering columns in Rails, cakephp style.

    - by Smickie
    CakePHP's built in pagination helpers automatically allow column ordering in the view. If you bake the view you get a link on each column to order it by that data. Is there a way to get this functionality in Rails? The standard will paginate doesn't offer it, anyone know any good ones?

  • MVC model flow?

    - by fuzzygoat
    I am setting up an application using the MVC model and I have a query regrading the flow of information from the UI to the data model. What I need to do is place data from the UI in the model, what I have done is write a method in the view which collects the required data in an object and then passes it to the model. The model then takes ownership of the data so that the view can release its ownership. Does this sound sensible?

  • iPhone: Push Navigation Controller (w/ TableViewController) onto stack. Is this possible?

    - by Nic Hubbard
    I have a view which contains a UIButton. When this is clicked, it calls a method that loads another NIB. Now, normally, that nib would load a view onto the stack, and everything would be fine. But, I am trying to load a Navigation Controller (so that I can have table views that are multiple levels deep), and all I get it errors. What is the proper method for loading a Navigation Controller and putting it on the top of the stack?

  • Strange error inserting new relationship data in core-data

    - by michael
    My app will allow users to create a personalised list of events from a large list of events. I have a table view which simply displays these events, tapping on one of them takes the user to the event details view, which has a button "add to my events". In this detailed view I own the original event object, retrieved via an NSFetchedResultsController and passed to the detailed view (via a table cell, the same as the core data recipes sample). I have no trouble retrieving/displaying information from this "event". I am then trying to add it to the list of MyEvents represented by a one to many (inverse) relationship: This code: NSManagedObjectContext *context = [event managedObjectContext]; MyEvents *myEvents = (MyEvents *)[NSEntityDescription insertNewObjectForEntityForName:@"MyEvents" inManagedObjectContext:context]; [myEvents addEventObject:event];//ERROR And this code (suggested below): //would this add to or overwrite the "list" i am attempting to maintain NSManagedObjectContext *context = [event managedObjectContext]; MyEvents *myEvents = (MyEvents *)[NSEntityDescription insertNewObjectForEntityForName:@"MyEvents" inManagedObjectContext:context]; NSMutableSet *myEvent = [myEvents mutableSetValueForKey:@"event"]; [myEvent addObject:event]; //ERROR Bot produce (at the line indicated by //ERROR): *** -[NSComparisonPredicate evaluateWithObject:]: message sent to deallocated instance Seems I may have missed something fundamental. I cant glean any more information through the use of debugging tools, with my knowledge of them. 1) Is this a valid way to compile and store an editable list like this? 2) Is there a better way? 3) What could possibly be the deallocated instance in error? -- I have now modified the Event entity to have a to-many relationship called "myEvents" which referrers to itself. I can add Events to this fine, and logging the object shows the correct memory addresses appearing for the relationship after a [event addMyEventObject:event];. The same failure happens right after this however. I am still at a loss to understand what is going wrong. This is the backtrace #0 0x01f753a7 in ___forwarding___ () #1 0x01f516c2 in __forwarding_prep_0___ () #2 0x01c5aa8f in -[NSFetchedResultsController(PrivateMethods) _preprocessUpdatedObjects:insertsInfo:deletesInfo:updatesInfo:sectionsWithDeletes:newSectionNames:treatAsRefreshes:] () #3 0x01c5d63b in -[NSFetchedResultsController(PrivateMethods) _managedObjectContextDidChange:] () #4 0x0002e63a in _nsnote_callback () #5 0x01f40005 in _CFXNotificationPostNotification () #6 0x0002bef0 in -[NSNotificationCenter postNotificationName:object:userInfo:] () #7 0x01bbe17d in -[NSManagedObjectContext(_NSInternalNotificationHandling) _postObjectsDidChangeNotificationWithUserInfo:] () #8 0x01c1d763 in -[NSManagedObjectContext(_NSInternalChangeProcessing) _createAndPostChangeNotification:withDeletions:withUpdates:withRefreshes:] () #9 0x01ba25ea in -[NSManagedObjectContext(_NSInternalChangeProcessing) _processRecentChanges:] () #10 0x01bdfb3a in -[NSManagedObjectContext processPendingChanges] () #11 0x01bd0957 in _performRunLoopAction () #12 0x01f4d252 in __CFRunLoopDoObservers () #13 0x01f4c65f in CFRunLoopRunSpecific () #14 0x01f4bc48 in CFRunLoopRunInMode () #15 0x0273878d in GSEventRunModal () #16 0x02738852 in GSEventRun () #17 0x002ba003 in UIApplicationMain () Cheers.

  • Detecting Touches in an OpenGL rendered scene

    - by Icky
    Hey. I was wondering whether there is a way to detect a touch in an OpenGL rendered scene. What I have i a set of images which are being rendered in my main view. Now if the user touches one of these images (or objects) I would like to know which one was touched - similar to the CGRectContainsPoint(frame, [touch locationInView:self.view] method. Is there an easy way to find out? If there is none, this would also help.

  • How to set property only on second column of a ListView?

    - by Lernkurve
    Introduction I have a ListView and want to format only the second column. The following XAML code does that: <ListView x:Name="listview"> <ListView.View> <GridView> <GridViewColumn Header="Property" DisplayMemberBinding="{Binding Path=Key}" Width="100"/> <!-- <GridViewColumn Header="Value" DisplayMemberBinding="{Binding Path=Value}" Width="250">--> <GridViewColumn Header="Value" Width="250"> <GridViewColumn.CellTemplate> <DataTemplate> <TextBlock Text="{Binding Path=Value}" Foreground="CornflowerBlue" AutomationProperties.Name={Binding Path="Key"}/> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> </GridView> </ListView.View> </ListView> The one problem I have is that the AutomationProperties.Name property is not being set. I was checking it with the Coded UI Test Builder and the property is empty. The Text and the Foreground property are being set correctly. Question Does anyone know why AutomationProperties.Name is not being set? Additional information Strangly enough, the following XAML code does set the AutomationProperties.Name <ListView x:Name="listview"> <ListView.Resources> <Style TargetType="TextBlock"> <Setter Property="AutomationProperties.Name" Value="{Binding Key}"/> </Style> </ListView.Resources> <ListView.View> <GridView> <GridViewColumn Header="Property" DisplayMemberBinding="{Binding Path=Key}" Width="100"/> <GridViewColumn Header="Value" DisplayMemberBinding="{Binding Path=Value}" Width="250"/> </GridView> </ListView.View> </ListView> The problem here though is that AutomationProperties.Name is being set on all the columns. But I only want it on the second one because otherwise my Coded UI Test code returns the wrong value (that of the first column, instead of that of the second column which I want).

  • How to check in which position (landscape or portrait) os the iPhone now?

    - by Mike Rychev
    I have an app with a tab bar, and nav controllers in each tab. When user shakes the device, a UIImageView appears as a child view in the nav controller. But the UIImageView must contain a special image, depending on the device's current orientation. If I write just - (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation) if (interfaceOrientation == UIInterfaceOrientationPortrait|| interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown) { //Code } else if (interfaceOrientation == UIInterfaceOrientationLandscapeRight||interfaceOrientation == UIInterfaceOrientationLandscapeLeft) { //Code } } The view just goes crazy if user rotated the device before shaking. Is there a method to get iPhones current orientation?
