  • Where to put constants in Rails

    - by Sam
    I have a few constants which are arrays that I don't want to create db's for but I don't know where to store the constants without getting errors. For example CONTAINER_SIZES = [["20 foot"],["40 foot"]] Where can I store this so all models and controller have access to this?

  • Graphical glitches when adding cells and scrolling with UITableView

    - by Daniel I-S
    I am using a UITableView to display the results of a series of calculations. When the user hits 'calculate', I wish to add the latest result to the screen. This is done by adding a new cell to a 'results' section. The UITableViewCell object is added to an array, and then I use the following code to add this new row to what is displayed on the screen: [thisView beginUpdates]; [thisView insertRowsAtIndexPaths:[NSArray arrayWithObject:newIndexPath] withRowAnimation: UITableViewRowAnimationFade]; [thisView endUpdates]; This results in the new cell being displayed. However, I then want to immediately scroll the screen down so that the new cell is the lowermost cell on-screen. I use the following code: [thisView scrollToRowAtIndexPath:newIndexPath atScrollPosition:UITableViewScrollPositionBottom animated:YES]; This almost works great. However, the first time a cell is added and scrolled to, it appears onscreen only briefly before vanishing. The view scrolls down to the correct place, but the cell is not there. Scrolling the view by hand until this invisible new cell's position is offscreen, then back again, causes the cell to appear - after which it behaves normally. This only happens the first time a cell is added; subsequent cells don't have this problem. It also happens regardless of the combination of scrollToRowAtIndexPath and insertRowsAtIndexPath animation settings. There is also a problem where, if new cells are added repeatedly and quickly, the new cells stop 'connecting up'. The lowermost cell in a group is supposed to have rounded corners, and when a new cell is added these turn into square corners so that there is a clean join with the next cell in the group. In this case, however, a cell often does not lose its rounded edges despite not being the last cell anymore. This also gets corrected once the affected area moves offscreen and back. This method of adding and scrolling would be perfect for my application if it weren't for these weird glitches. Any ideas as to what I may be doing wrong?

  • Skip HTML escape in custom label_tag helper in Rail 3

    - by tricote
    Hi, I have this nice class ErrorFormBuilder that allows me to add the error description near the corresponding field in the form view : class ErrorFormBuilder < ActionView::Helpers::FormBuilder #Adds error message directly inline to a form label #Accepts all the options normall passed to form.label as well as: # :hide_errors - true if you don't want errors displayed on this label # :additional_text - Will add additional text after the error message or after the label if no errors def label(method, text = nil, options = {}) #Check to see if text for this label has been supplied and humanize the field name if not. text = text || method.to_s.humanize #Get a reference to the model object object = @template.instance_variable_get("@#{@object_name}") #Make sure we have an object and we're not told to hide errors for this label unless object.nil? || options[:hide_errors] #Check if there are any errors for this field in the model errors = object.errors.on(method.to_sym) if errors #Generate the label using the text as well as the error message wrapped in a span with error class text += " <br/><span class=\"error\">#{errors.is_a?(Array) ? errors.first : errors}</span>" end end #Add any additional text that might be needed on the label text += " #{options[:additional_text]}" if options[:additional_text] #Finally hand off to super to deal with the display of the label super(method, text, options) end end But the HTML : text += " <br/><span class=\"error\">#{errors.is_a?(Array) ? errors.first : errors}</span>" is escaped by default in the view... I tried to add the {:escape = false} option : super(method, text, options.merge({:escape => false})) without success Is there any way to bypass this behavior ? Thanks

  • Fixed div once page is scrolled is flickering

    - by jasondavis
    I am trying to have an advertisement block/div that will be hald way down the page, once you scroll do the page to this point it will stick to the top. Here is a demo of what I am trying to do and the code I am using to do it with... http://jsfiddle.net/jasondavis/6vpA7/3/embedded/result/ In the demo it works perfectly how I am wanting it to be, however when I implement it on my live site, http://goo.gl/zuaZx it works but when you scroll down the div flickers in and out of view on each scroll or down key press. On my site to see the problem live it is the blokc on the right sidebar that says "Recommended Books" Here is the code I am using... $(document).ready( function() { $(window).scroll( function() { if ($(window).scrollTop() > $('#social-container').offset().top) $('#social').addClass('floating'); else $('#social').removeClass('floating'); } ); } );? css #social.floating { position: fixed; top: 0; }? My demo jsfiddle where it works correctly http://jsfiddle.net/jasondavis/6vpA7/3/ The only thing different on my live site is the div/id name is different. As you can see it is somewhat working on my live site except the flickering in and out of view as you scroll down the page. Anyone have any ideas why this would happen on my live site and not on my jsfiddle demo?

  • C# Fun with Generics - Mutual Dependencies

    - by Kenneth Cochran
    As an experiment I'm trying to write a generic MVP framework. I started with: public interface IPresenter<TView> where TView: IView<IPresenter<... { TView View { get; set;} } public interface IView<TPresenter> where TPresenter:IPresenter<IView<... { TPresenter Presenter { get; set; } } Obviously this can't work because the types of TView and TPresenter can't be resolved. You'd be writing Type<Type<... forever. So my next attempt looked like this: public interface IView<T> where T:IPresenter { ... } public interface IView:IView<IPresenter> { } public interface IPresenter<TView> where TView: IView { ... } public interface IPresenter: IPresenter<IView> { ... } This actually compiles and you can even inherit from these interfaces like so: public class MyView : IView, IView<MyPresenter> { ... } public class MyPresenter : IPresenter, IPresenter<MyView> { ... } The problem is in the class definition you have to define any members declared in the generic type twice. Not ideal but it still compiles. The problem's start creeping up when you actually try to access the members of a Presenter from a View or vice versa. You get an Ambiguous reference when you try to compile. Is there any way to avoid this double implementation of a member when you inherit from both interfaces? Is it even possible to resolve two mutually dependent generic types at compile time?

  • Custom Button on top of another custom button?

    - by Jim
    I'm trying to make two custom buttons in code. One that fills the full screen with a small button on top. The problem I'm having is the larger button is triggered when the smaller button is tapped. I've tried doing exactly the same thing with IB and it works. Is there some sort of trapping/masking method that I need to use with code? I've checked the documentation and not come across anything that would suggest why this is happening. CGRect bFrame = CGRectMake(0, 0, 320, 480); UIButton *cancelButton = [[UIButton alloc] init]; cancelButton = [UIButton buttonWithType:UIButtonTypeCustom]; cancelButton.frame = bFrame; [cancelButton setBackgroundColor:[UIColor clearColor]]; [cancelButton addTarget:self action:@selector(animate:) forControlEvents:UIControlEventTouchUpInside]; UIButton *priceButton = [[UIButton alloc] init]; priceButton.center = CGPointMake(228, 98); [priceButton addTarget:self action:@selector(callNumber:) forControlEvents:UIControlEventTouchUpInside]; [priceButton setTitle:@"BUY" forState:UIControlStateNormal]; //[cancelButton addSubview:priceButton]; [self.view addSubview:cancelButton]; [self.view bringSubviewToFront:priceButton];

  • ContentNegotiatingViewResolver Issue

    - by Jay
    How to map a url of this kind "/myapp/sample" to map to the default MarshallingView instead of a JSTLView. @RequestMapping("/vets") public ModelMap vetsHandler() { Vets vets = new Vets(); vets.getVetList().addAll(this.clinic.getVets()); return new ModelMap(vets); } The above code works fine. When i tried to use http://.../vets.xml, I was able to download the xml. But, @RequestMapping("/myapp/vets") public ModelMap vetsHandler() { Vets vets = new Vets(); vets.getVetList().addAll(this.clinic.getVets()); return new ModelMap(vets); } doesn't resolve to the XML MarshalView, instead it resolves to JSTLView. Any thoughts? below is the spring v 3 configuration from the petclinic example, that i'm using. <bean id="vets" class="org.springframework.web.servlet.view.xml.MarshallingView"> <property name="contentType" value="application/vnd.springsource.samples.petclinic+xml"/> <property name="marshaller" ref="marshaller"/> </bean> <bean id="test" class="org.springframework.web.servlet.view.xml.MarshallingView"> <property name="contentType" value="application/vnd.springsource.samples.petclinic+xml"/> <property name="marshaller" ref="marshaller"/> </bean> <oxm:jaxb2-marshaller id="marshaller"> <oxm:class-to-be-bound name="org.springframework.samples.petclinic.Vets"/> <oxm:class-to-be-bound name="org.springframework.samples.petclinic.Test1"/> </oxm:jaxb2-marshaller>

  • TextField Covering UIAlertView's Button.

    - by XcodeDev
    Hi, I am using a UIAlertView with three buttons: "Dismiss", "Submit Score" and @"View Leaderboard". The UIAlertView also contains a UITextField called username. At the moment the UITextField "username" is covering one of the buttons in the UIAlertView. I just wanted to know how I could stop the UITextField from covering one of the buttons, i.e move the buttons down. Here is an image of what is happening: And here is my code: [username setBackgroundColor:[UIColor whiteColor]]; [username setBorderStyle:UITextBorderStyleRoundRect]; username.backgroundColor = [UIColor clearColor]; username.returnKeyType = UIReturnKeyDone; username.keyboardAppearance = UIKeyboardAppearanceAlert; username.placeholder = @"Enter your name here"; username = [[UITextField alloc] initWithFrame:CGRectMake(20.0, 45.0, 245.0, 25.0)]; username.borderStyle = UITextBorderStyleRoundedRect; [username resignFirstResponder]; UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Congratulations" message:[NSString stringWithFormat:@"You tapped %i times in %i seconds!\n", tapAmount, originalCountdownTime] delegate:self cancelButtonTitle:@"Dismiss" otherButtonTitles:@"Submit To High Score Leaderboard", @"View Leaderboard", nil]; alert.tag = 01; [alert addSubview:username]; [alert show]; [alert release];

  • Problems with CGPoint/touches event

    - by Jason
    I'm having some problems with storing variables from my touch events. The warning I get when I run this is that coord and icoord are unused, but I used them in the viewDidLoad implementation, is there a reason why this does not work? Any suggestions? #import "iGameViewController.h" @implementation iGameViewController @synthesize player; -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [[event allTouches] anyObject]; CGPoint icoord = [touch locationInView:touch.view]; } -(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [[event allTouches] anyObject]; CGPoint coord = [touch locationInView:touch.view]; } - (void)viewDidLoad { if (coord.x > icoord.x) { player.center = CGPointMake(player.center.x + 5, player.center.y); } if (coord.x < icoord.x) { player.center = CGPointMake(player.center.x - 5, player.center.y); } if (coord.y > icoord.y) { player.center = CGPointMake(player.center.x, player.center.y - 5); } if (coord.y < icoord.y) { player.center = CGPointMake(player.center.x, player.center.y + 5); } } Thanks.

  • VSTO - Outlook 2007 How do I show a user property even when it's not present?

    - by Yandros
    I have added user property in a mail folder, let's call it UserProperty01. Some of the folder items have this property, some don't. I need to show in the folder's view if that property is set or not, so I added another property called UserProperty01Present, and I set it to true when I set the original property and false when I deleted it; then I added it to the folder's view. The problem is that the little checkbox appears checked in those mails where the property is set, blank in those where the property was deleted... and nowhere at all in those where the property was never set in the first place. My question is, is there any way to show the blank checkbox when the property is not set? The only alternative I found so far is looking in every mail item and setting it to false when it's not set every time the folder is opened; needless to say, I'm not very happy with this solution. Is there any other way? Thank you for your time.

  • Ajax problem after deleting a div, then creating a new one

    - by Matt Nathanson
    I'm building a custom CMS where you can add and delete clients using ajax and jquery 1.4.2. My problem lies after I delete a div. The ajax is used to complete this and refresh automatically.. But when I go to create a new div (without a hard refresh) it puts it back in the slot of the div I just deleted. How can I get this to completely forget about the div i just deleted and place the new div in the next database table? link for reference: http://staging.sneakattackmedia.com/cms/ //Add New client // function AddNewClient() { dataToLoad = 'addClient=yes'; $.ajax({ type: 'post', url: '/clients/controller.php', datatype: 'html', data: dataToLoad, target: ('#clientssidebar'), async: false, success: function(html){ $(this).click(function() {reInitialize()}); //$('#clientssidebar').html(html); $('div#' + clientID).slideDown(800); $(this).click(function() { ExpandSidebar()});}, error: function() { alert('An error occured! 222');} });}; //Delete Client // function DeleteClient(){ var yes = confirm("Whoa there chief! Do you really want to DELETE this client?"); if (yes == 1) { dataToLoad = 'clientID=' + clientID + '&deleteClient=yes', $.ajax({ type: 'post', url: '/clients/controller.php', datatype: 'html', data: dataToLoad, success: function(html) { alert('Client' + clientID + ' should have been deleted from the database.'); $(this).click(function() {reInitialize()}); $('div#' +clientID).slideUp(800); }, error: function() { alert('error'); }});};}; //Re Initialize // function reInitialize() { $('#addnew').click(function() {AddNewClient()}); $('.deletebutton').click(function() {clientID = $(this).parent().attr('id'); DeleteClient()}) $('.clientblock').click(function() {clientID = $(this).attr('id'); ExpandSidebar()});}; //Document Ready // $(document).ready(function(){ if ($('isCMS')){ editCMS = 1; $('.deletebutton').click(function() {clientID = $(this).parent().attr('id'); DeleteClient()}); $('#addnew').click(function() {AddNewClient()}); $('.clientblock').click(function() {clientID = $(this).attr('id'); ExpandSidebar()}); $('.clientblock').click(function() {if (clickClient ==true) { $(this).css('background-image', 'url(/images/highlightclient.png)'); $(this).css('margin-left' , '30px'); }; $(this).click(function(){ $(this).css('background-image', ''); }); $('.uploadbutton').click(function(){UploadThings()}); }); } else ($('#clientscontainer')) { $('#editbutton').css('display', 'none'); }; }); Please help!!!

  • How do I reference my MainViewController from another class?

    - by todd412
    Hi, I am building an iPhone Utility app that uses UIImageView to display an animation. Within the MainViewController's viewDidLoad() method, I am creating an instance of a CustomClass, and then setting up the animations: - (void)viewDidLoad { [super viewDidLoad]; cc = [CustomClass new]; NSArray * imageArray = [[NSArray alloc] initWithObjects: [UIImage imageNamed:@"image-1-off.jpg"], [UIImage imageNamed:@"image-2-off.jpg"], [UIImage imageNamed:@"image-3-off.jpg"], [UIImage imageNamed:@"image-4-off.jpg"], nil]; offSequence = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)]; offSequence.animationImages = imageArray; offSequence.animationDuration = .8; offSequence.contentMode = UIViewContentModeBottomLeft; [self.view addSubview:offSequence]; [offSequence startAnimating]; } That works fine. However, I would like to be able to move all the above code that sets up the UIImageView into my CustomClass. The problem is in the second to last line: [self.view addSubview:offSequence]; I basically need to replace 'self' with a reference to the MainControllerView, so I can call addSubview from within my CustomClass. I tried creating an instance var of CustomClass called mvc and a setter method that takes a reference to the MainViewController as an argument as such: - (void) setMainViewController: (MainViewController *) the_mvc { mvc = the_mvc; } And then I called it within MainViewController like so: [cc setMainController:MainViewController:self]; But this yields all sorts of errors which I can post here, but it strikes me that I may be overcomplicating this. Is there an easier way to reference the MainViewController that instanatiated my CustomClass?

  • jQuery click event on image only fires once

    - by stephenreece@
    I created a view of thumbnails. When the user clicks, I want the real image to pop-up in a dialog. That works the first time, but once the jQuery 'click' fires on an thumbnail it never fires again unless I reload the entire page. I've tried rebinding the click events on the dialog close that that does not help. Here is my code: function LoadGalleryView() { $('img.gallery').each(function(){ BindImage($(this)); }); } function BindImage(image) { var src= image.attr('src'); var id= image.attr('id'); var popurl = src.replace("thumbs/", ""); image.hover(function(){ image.attr('style', 'height: 100%; width: 100%;'); }, function(){ image.removeAttr('style'); }); $('#'+id).live('click', function() { PopUpImage(popurl); }); } function CheckImage(img,html) { if ( img.complete ) { $('#galleryProgress').html(''); var imgwidth = img.width+35; var imgheight = img.height+65; $('<div id="viewImage" title="View"></div>').html(html).dialog( { bgiframe: true, autoOpen: true, modal: true, width: imgwidth, height: imgheight, position: 'center', closeOnEscape: true }); } else { $('#galleryProgress').html('<img src="images/ajax-loader.gif" /><br /><br />'); setTimeout(function(){CheckImage(img,html);},10); } } function PopUpImage(url) { var html = '<img src="'+url+'" />'; var img = new Image(); img.src = url; if ( ! img.complete ) { setTimeout(function(){CheckImage(img,html);},10); } } PopUpImage() only executes the first time an image is clicked and I cannot figure out how to rebind.

  • How to add images while moving finger across UIView?

    - by Luke Irvin
    I am having issues adding an image across a view while moving finger across the screen. Currently it is adding the image multiple times but squeezing them too close together and not really following my touch. Here is what I am trying: -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch * touch = [touches anyObject]; touchPoint = [touch locationInView:imageView]; if (touchPoint.x > 0 && touchPoint.y > 0) { _aImageView = [[UIImageView alloc] initWithImage:aImage]; _aImageView.multipleTouchEnabled = YES; _aImageView.userInteractionEnabled = YES; [_aImageView setFrame:CGRectMake(touchPoint.x, touchPoint.y, 80.0, 80.0)]; [imageView addSubview:_aImageView]; [_aImageView release]; } } -(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { [self touchesBegan:touches withEvent:event]; } Any suggestions is much appreciated. EDIT: What I want: After taking or choosing an image, the user can then select another image from a list. I want the user to touch and move their finger across the view and the selected image will appear where they drag their finger, without overlapping, in each location.
