Writing To The Response in Rails? (Like "echo" in PHP)

- by Yar

I know that I can do this in Rails: <%="hello" %> but is there any way to do this <% echo "hello" %> and get it to show up in the response? I have tried response.write which almost worked, but did not... Edit: print or puts do not do it, because I do not want to write to the console. I want to write to the browser/HTTP client. Edit: Here is an example: <% unless @research_activities.size == 0 concat(render(:partial => 'list')) end %> Why would I want to include two closing tags just to do that? It reads nicely in code, doesn't it?

Cocoa (Touch) for Swing Developers #1: Where Are the Layouts?

- by yar

My iPhone SDK and Objective-C learning is moving ahead quickly, thanks to several great books and online help (including this one). But I do have some basic questions due to what I already know that will be answered eventually, but I'd rather get a heads-up now if possible :) Are there equivalents for LayoutManagers in Cocoa Touch? Are they used, or is absolute positioning used instead? I have seen some of the layout stuff in IB, but I'm not sure what to look at in code. Aside from using the IB, are UIControls added directly to UIView instances using the addSubview (like add in Swing)? These are just two concrete questions that I've thought of just now, but I would love to see any translation of Swing concepts to Cocoa Touch.

- by PerwyL

Hi Everyone this is what i want to achieve 1) Have a page control that allows user to do a swipe to 6 different pages 2) each page is a table view controller 3) everything is done via code NOT IB The tutorials that are i find either use VIEW CONTROLLER or is done via IB. I am not very good with IB and prefer to have everything done via coding. I have a TableViewController.h and TableViewController.m When the user navigate to the TableViewController view, my application will display a table view (filled with some information), when the user swip to the next page, another page (table view) will appear with another set of information... I am very new to objective-c and iphone programing...can some one pls guide me on how to achieve the above or is there another way to doing things? oh yar....i have a tab bar controller as my root controller...and for one of the tab (tab A) i have a navigation controller and my TableViewControllers falls inside tab A. THANKS IN ADVANCE!!!

extracting multiple tags from xml using PHP

- by user1479431

Here is my address.xml <?xml version="1.0" ?>  <AddressBook> <Addressentry> <firstName>jack</firstName> <lastName>S</lastName> <Address>2899,Ray Road</Address> <Email>[email protected]</Email> </Addressentry> <Addressentry> <firstName>Sid</firstName> <lastName>K</lastName> <Address>238,Baseline Road,TX</Address> <Email>[email protected]</Email> <Email>[email protected]</Email> </Addressentry> <Addressentry> <firstName>Satya</firstName> <lastName>Yar</lastName> <Address>6,Rural Road,Tempe,AZ</Address> <Email>[email protected]</Email> <Email>[email protected]</Email> <Email>[email protected]</Email> </Addressentry> </AddressBook> I am trying to load all the entries using PHP code as below. Each addressentry can have one or more tags. Right now from the code below I am able to extract only one tag. My question is how do I extract all tags associated with particular Addressentry. that is I want to print all emails on the same line. <?php $theData = simplexml_load_File("address.xml"); foreach($theData->Addressentry as $theAddress) { $theFirstName = $theAddress->firstName; $theLastName = $theAddress->lastName; $theAdd = $theAddress->Address; echo "".$theFirstName." ".$theLastName." ".$theAdd." ".$theAddress->Email." "; unset($theFirstName); unset($theLastName); unset($theAdd); unset($theEmail); } ?> Any help would be appreciated
