• how to remove .php from a certain file (with apache .htaccess)

  - by user2015253

  I want a certain file (only this!) to remove the php extension for calling it. BUT: It uses get parameters and they should remain! I tried it with my .htaccess and something like: RewriteEngine on followed by either RewriteRule ^file(.*)$ file.php$1 or RewriteRule ^file(.+)$ file.php$1 but it doesn't work. (First gives error 500, second gives 404) Example what I want to call in the browser: file?param=asd&foo=bar - It should call as: file.php?param=asd&foo=bar

RadRails has a "Switch to Test" function for my controller, model, etc. but not for my library. if I have class Foo::Bar in /lib/foo/bar.rb, where should I put the unittest for it? or should I separate the foo library in a separated project? Thanks.

• Rails: Why does find_by not work on my ActiveRecord model?

  - by randombits

  I have a simple model named Foo. Foo has two columns, bar and foobar. Doing a simple Foo.find_by_bar("a") is returning nil. There is a record in the table where bar contains a. Also, what's even more troubling, is I don't see the query even happening in the development log. A simple Foo.find(1) works though.

• My UITabBarController isn't appearing, but its first view is?

  - by E-Madd

  I've done some reorganizing of my project recently and now I'm not seeing my tab bar controller, but its first view controller's view is appearing. Here's a breakdown of everything that happens prior to the problem. App Delegate loads FirstViewController with nib. FirstViewController loads the application data from my server and then presents MainViewController with a modal transition. MainViewController is where the UITabBarController is supposed to be appearing. It's a very simple class. The .h @interface MainViewController : UIViewController <UITabBarControllerDelegate> { IBOutlet UITabBarController *tabBarController; } @property (nonatomic, retain) UITabBarController *tabBarController; @end The .m @implementation MainViewController @synthesize tabBarController; - (void)viewDidLoad { NSLog(@"MainViewController viewDidLoad"); //set tab bar controller delegate to self tabBarController.delegate = self; // home view HomeViewController *home = [[HomeViewController alloc] initWithTab]; // menu view MenuViewController *menu = [[MenuViewController alloc] initWithTab]; // special offers view SpecialOffersViewController *so = [[SpecialOffersViewController alloc] initWithTab]; // events view EventsViewController *events = [[EventsViewController alloc] initWithTab]; // info view InfoViewController *info = [[InfoViewController alloc] initWithTab]; //populate the tab bar controller with view controllers NSArray *controllers = [NSArray arrayWithObjects:home, menu, so, events, info, nil]; tabBarController.viewControllers = controllers; //release view controllers [home release]; [menu release]; [so release]; [events release]; [info release]; [controllers release]; //add tab bar controller to view [self.view addSubview:tabBarController.view]; [super viewDidLoad]; } and here's the bit from FirstViewController that modally presents the MainViewController... MainViewController *controller = [[MainViewController alloc] initWithNibName:@"MainViewController" bundle:nil]; controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:controller animated:YES]; [controller release]; I'm not getting any compiler errors or warnings and the app runs swell... no crashing. It just isn't showing the darned TabBar, and it used to when I was creating it on my AppDelegate. I checked everything in my NIB and my outlets seem to be hooked up ok. I have no idea what's happened. Help!

  - by furstgurshnur

Technically /blah doesn't exist, but I was hoping to have the server redirect before it gets to that point. Has anyone had to do this before? What was the solution?

• Is there a way to loop through and execute all of the functions in a Python class?

  - by curious

  I have class Foo(): function bar(): pass function foobar(): pass Rather than executing each function one by one as follows: x = Foo() x.bar() x.foobar() is there a built-in way to loop through and execute each function in the sequence in which they are written in the class? It doesn't matter whether the solution is to add code to the class Foo(), or to do something to x.

  - by Joel

  Hi folks. I'm just putting together a simple nav bar using something similar to this tutorial: http://www.cssnewbie.com/horizontal-dropdown-menus/ The thing is, that I'd like to have the children lists first item to line up directly below the parent. Right now, they just go wherever I float them. Is there a way to do this without absolute positioning? I'd like to achieve something similar to what these guys have in their top nav bar: http://michaelfranti.com/
