  • Does it make sense to fragment cache static partials

    - by ash34
    Hi, I have my views and layouts split into multiple partials, some of them are static partials i.e, no data from the database being displayed here. Does it make sense to cache these to prevent the erb templating system from generating the html each time or it only makes sense to cache in situations where something needs to be retrieved from the db each time. thanks, ash

  • iPhone SDK: Know when tab on Tab Bar is clicked?

    - by Nic Hubbard
    I have a tab bar which displays different views when clicked. When you click a tab for the first time, it calls the viewDidLoad method. But, it only calls that the first time. Is there a method that is called when a user clicks back to that tab, since the viewDidLoad won't be called that second time? (I need to do this to update a UITableView when the user clicks back to a tab)

  • Looking for Reachability (2.0) Use Case Validation

    - by user350243
    There is so much info out there on using Apple's Reachability example, and so much is conflicting. I'm trying to find out of I'm using it (Reachability 2.0) correctly below. My App use case is this: If an internet connection is available through any means (wifi, LAN, Edge, 3G, etc.) a UIButton ("See More") is visible on various views. If no connection, the button is not visible. The "See More" part is NOT critical in any way to the app, it's just an add-on feature. "See More" could be visible or not anytime during the application lifecycle as connection is established or lost. Here's how I did it - Is this correct and/or is there a better way? Any help is Greatly Appreciated! lq // AppDelegate.h #import "RootViewController.h" @class Reachability; @interface AppDelegate : NSObject <UIApplicationDelegate> { UIWindow *window; UINavigationController *navigationController; RootViewController *rootViewController; Reachability* hostReach; // NOT USED: Reachability* internetReach; // NOT USED: Reachability* wifiReach; } @property (nonatomic, retain) IBOutlet UIWindow *window; @property (nonatomic, retain) IBOutlet UINavigationController *navigationController; @property (nonatomic, retain) IBOutlet RootViewController *rootViewController; @end // AppDelegate.m #import "AppDelegate.h" #import "Reachability.h" #define kHostName @"www.somewebsite.com" @implementation AppDelegate @synthesize window; @synthesize navigationController; @synthesize rootViewController; - (void) updateInterfaceWithReachability: (Reachability*) curReach { if(curReach == hostReach) { NetworkStatus netStatus = [curReach currentReachabilityStatus]; BOOL connectionRequired = [curReach connectionRequired]; // Set a Reachability BOOL value flag in rootViewController // to be referenced when opening various views if ((netStatus != ReachableViaWiFi) && (netStatus != ReachableViaWWAN)) { rootViewController.bConnection = (BOOL *)0; } else { rootViewController.bConnection = (BOOL *)1; } } } - (void) reachabilityChanged: (NSNotification* )note { Reachability* curReach = [note object]; NSParameterAssert([curReach isKindOfClass: [Reachability class]]); [self updateInterfaceWithReachability: curReach]; } - (void)applicationDidFinishLaunching:(UIApplication *)application { // NOTE: #DEFINE in Reachability.h: // #define kReachabilityChangedNotification @"kNetworkReachabilityChangedNotification" [[NSNotificationCenter defaultCenter] addObserver: self selector: @selector(reachabilityChanged:) name: kReachabilityChangedNotification object: nil]; hostReach = [[Reachability reachabilityWithHostName: kHostName] retain]; [hostReach startNotifer]; [self updateInterfaceWithReachability: hostReach]; [window addSubview:[navigationController view]]; [window makeKeyAndVisible]; } - (void)dealloc { [navigationController release]; [rootViewController release]; [window release]; [super dealloc]; } @end

  • Should I use a resource loader for a SPA, or front-load everything?

    - by Shango
    I've been getting into Backbone.js lately and I'm enjoying it so far. All the examples tend to be simple to-do lists, so it's been a little difficult extrapolating code organization and file structure for a larger/more robust single page application. I've come to a crossroad: Should I use something like Yepnope.js to load models and views as I need them or, Combine and minify into fewer files and front-load it all. Some combination of both? Any advice would be appreciated!

  • iPhone: Grouped tables and navigation controller issues

    - by Jack Griffiths
    Hi there, I've set up a grouped table on my app, and pushing to new views works fine. Except for one thing. The titles and stack layout are all weird. Here's the breakdown: I have two sections in my table. When I tap on the first row in the first section, it takes me to the correct view, but the title of the new view is the name of the first row in the second section of the table. In turn, the second row in the first section's title is the second row in the second section's title. If I tap on the second row in the second section of the root view table, the navigation button goes to the second row in the first section of the table. So here's a diagram of my table: Table Section 1 Row 1 Row 2 Row 3 Table Section 2 Row A Row B Row C So if I tap on row 3, the title of the pushed view is Row C. The navigation button tells me to go back to Row 3, then eventually ending up at the root view. Here's my implementation file pushing the views: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { //CSS if ([[arryClientSide objectAtIndex:indexPath.row] isEqual:@"CSS"]) { CSSViewController *css = [[CSSViewController alloc] initWithNibName:@"CSSViewController" bundle:nil]; [css setTitle:@"CSS"]; [self.navigationController pushViewController:css animated:YES]; } //HTML if ([[arryClientSide objectAtIndex:indexPath.row] isEqual:@"HTML"]) { HTMLViewController *html = [[HTMLViewController alloc] initWithNibName:@"HTMLViewController" bundle:nil]; [html setTitle:@"HTML"]; [self.navigationController pushViewController:html animated:YES]; } //JS if ([[arryClientSide objectAtIndex:indexPath.row] isEqual:@"JavaScript"]) { JSViewController *js = [[JSViewController alloc] initWithNibName:@"JSViewController" bundle:nil]; [js setTitle:@"JavaScript"]; [self.navigationController pushViewController:js animated:YES]; } //PHP if ([[arryServerSide objectAtIndex:indexPath.row] isEqual:@"PHP"]) { PHPViewController *php = [[PHPViewController alloc] initWithNibName:@"PHPViewController" bundle:nil]; [php setTitle:@"PHP"]; [self.navigationController pushViewController:php animated:YES]; } //SQL if ([[arryServerSide objectAtIndex:indexPath.row] isEqual:@"SQL"]) { SQLViewController *sql = [[SQLViewController alloc] initWithNibName:@"SQLViewController" bundle:nil]; [sql setTitle:@"SQL"]; [self.navigationController pushViewController:sql animated:YES]; } & the array feeding the table's data: - (void)viewDidLoad { [super viewDidLoad]; arryClientSide = [[NSArray alloc] initWithObjects:@"CSS",@"HTML",@"JavaScript",nil]; arryServerSide = [[NSArray alloc] initWithObjects:@"Objective-C", @"PHP",@"SQL",nil]; // arryResources = [[NSArray alloc] initWithObjects:@"HTML Colour Codes", @"Useful Resources", @"About",nil]; self.title = @"Select a Language"; [super viewDidLoad]; // Uncomment the following line to display an Edit button in the navigation bar for this view controller. // self.navigationItem.rightBarButtonItem = self.editButtonItem; } Any help would be greatly appreciated.

    - by NoelAdy
    I have been using CouchDB on some prototype applications and it has been brilliant, very easy to use and extremely quick. I was wondering if anyone has been using it in production and have any views on it's reliability, performance suitability for operational management etc ?? I am considering using it to support a service layer and would make use of its replication functionality. Any comments/experiences would be most welcome.

  • Thin & Sinatra not taking port

    - by NekoNova
    I'm having problems settig up my application using Thin and Sinatra. I have created a development-config.ru file that contains the following settings: # This is a rack configuration file to fire up the Sinatra application. # This allows better control and configuration as we are using the modular # approach here for controlling our application. # # Extend the Ruby load path with the root of the API and the lib folder # so that we can automatically include all our own custom classes. This makes # the requiring of files a bit cleaner and easier to maintain. # This is basically what rails does as well. # We also store the root of the API in the ENV settings to ensure we have # always access to the root of the API when building paths. ENV['API_ROOT'] = File.dirname(__FILE__) $:.unshift ENV['API_ROOT'] $:.unshift File.expand_path(File.join(ENV['API_ROOT'], 'lib')) $:.unshift File.expand_path(File.join(ENV['API_ROOT'], 'db')) # Now we can require all the gems used for the entire API by simpling requiring # them here. We can also include the classes that we have defined inside the lib # folder. require 'rubygems' require 'bundler' # Run Bundler to setup our gems properly. This will install all the missing gems on # the system and ensure that the deployment environment is ready to run. Bundler.require # To make the loading easier for the application, we will now automatically load all # models that have been defined inside the lib folder. This ensures that we do not need # to load them anymore anywhere else in our application, as the models will be known to # ruby everywhere. Dir.glob(File.join(ENV['API_ROOT'], 'lib', '**', '*.rb')).each{|file| require file} # Now we will configure the Sinatra application so that we can fire up the entire API. # This requires some detailed settings like whether logging is allowed, the port to be # used and some folder locations. require 'sinatra' require 'app' set :logging, true set :dump_errors, true set :port, 3001 set :views, "#{ENV['API_ROOT']}/views" set :public_folder, "#{ENV['API_ROOT']}/public" set :environment, :test # Start up the Sinatra application with all the settings that we have defined. run App.new This is based upon the information I found on the Sinatra website. However, the problem is that I cannot get the application running on port 3001. If I use thin start -R development-config.ru it runs on port 3000. If I use rackup config-development.ru it runs on port 9696. However I never see Sinatra kick in or run over port 3000. My application looks like this: # Author : Arne De Herdt # Email : # This is the actuall application that will be running under Sinatra # to serve the requests for the billing middleware API. # We use the modular approach here to allow control when deploying # the application using Capistrano. require 'sinatra/base' require 'logger' require 'savon' require 'billcrux' class App < Sinatra::Base # This action responds to POST requests on the URI '/billcrux/register' # and is responsible for handeling registration requests with the # BillCrux payment system. # The post "/billcrux/register" do # do stuff end end Can someone tell me what I am doing wrong?

  • How to mask an view with an black-white image?

    - by mystify
    I've heard that it's possible to mask views with black/white images, where black means fully transparent and white means view is visible. The big difference to clipsToBounds is that the view could be clipped in funny shapes like circles or stars. How could I do that?

  • Django template can't see CSS files

    - by Technical Bard
    I'm building a django app and I can't get the templates to see the CSS files... My settings.py file looks like: MEDIA_ROOT = os.path.join(os.path.abspath(os.path.dirname(__file__)), 'media') MEDIA_URL = '/media/' I've got the CSS files in /mysite/media/css/ and the template code contains: <link rel="stylesheet" type="text/css" href="/media/css/site_base.css" />` then, in the url.py file I have: # DEVELOPMENT ONLY (r'^media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': '/media'}), but the development server serves the plain html (without styles). What am I doing wrong?

  • Unexpected tag T_ECHO in inline if

    - by Lombo
    I have something like this in one of my views <li <?php $isCurrent ? echo 'class="current"' : ''?> > <a href="SOME_LINK" class="SOME_CLASS">SOME_TEXT</a> </li> This causes a syntax error, unexpected T_ECHO. Changing echo for print solves the issue, but I would like to understand why I cannot use echo.

  • Scaffold is ignoring class file in CakePHP

    - by JoseMarmolejos
    Hi, when using scaffolding on a controller the views render fine and the app even attempts to insert the data; the problem is that the scaffold is completely ignoring the relations I'm defining in my model class, in fact it's ignoring the class entirely as I can delete the file and the controller still scaffolds and render the crud from the table. Has this ever happened to you?

    Many are saying that Apple has restricted it for better performance. It should increase the size of RAM to support multitasking. So, they Apple is not allowing it. But some say that Cocoa Touch applications can't be multitasking as iPhone has only one window and views on it. But I could not understand what is the correct reason for this ? Please clarify me.
