• Ruby on Rails: Unit Testing non activerecord models and still load fixtures

  - by Vaibhav Gumashta

  I may be missing something but I am stuck in this scenario: I have a non activerecord model, which I want to test. I have derived its test case class from: Test::Unit::TestCase. However, the test case class for the model, uses within itself, other activerecord model classes and I want to load fixtures for them. My problem is that the fixtures class method is available only when I subclass the test case class from ActiveSupport::TestCase (it is defined within ActiveRecord::TestFixtures which gets included in ActiveSupport::TestCase). Any help, coz running the tests gives me the error: undefined method "fixtures" (which is understandable) and in case I derive my test case class from ActiveSupport::TestCase it complains that there is no corresponding DB table. Also, I don't want to create a dummy table for backing my model class. Thanks a ton!

• Help with Oracle SQL Count function! =)

  - by user363024

  Hi guys.. The question im struggling with is this: i have a list of helicopter names in different charters and i need to find out WHICH helicopter has the least amount of charters booked. Once i find that out i need to ONLY display the one that has the least.

Something like Where MIN = MIN Value Id really appreciate it

• Android RelativeLayout spacing

  - by fordays

  Hi, I'm just putting the finishing touches to my Android app. Unfortunately, I dug straight into development without reading the documentation and built my layout with AbsoluteLayout and it turned out to look terrible when I loaded the app on my phone. Now I'm redoing the UI in a RelativeLayout and I want to put empty canvas space in between my ViewGroups in the y-direction. I am currently achieving this by putting random TextView sentences that are of the same color as my View's background in order to make psuedo-empty space. Is there a better way to do this, because right now when I define a specific ViewGroup to be placed below another View, it gets stuck right below the top View. As I was writing this, it dawned upon me that using padding might be the answer.... Any other suggestions?

• Interacting With Class Objects in Ruby

  - by michaelmichael

  How can I interact with objects I've created based on their given attributes in Ruby? To give some context, I'm parsing a text file that might have several hundred entries like the following: ASIN: B00137RNIQ -------------------------Status Info------------------------- Upload created: 2010-04-09 09:33:45 Upload state: Imported Upload state id: 3 I can parse the above with regular expressions and use the data to create new objects in a "Product" class: class Product attr_reader :asin, :creation_date, :upload_state, :upload_state_id def initialize(asin, creation_date, upload_state, upload_state_id) @asin = asin @creation_date = creation_date @upload_state = upload_state @upload_state_id = upload_state_id end end After parsing, the raw text from above will be stored in an object that look like this: [#<Product:0x00000101006ef8 @asin="B00137RNIQ", @creation_date="2010-04-09 09:33:45 ", @upload_state="Imported ", @upload_state_id="3">] How can I then interact with the newly created class objects? For example, how might I pull all the creation dates for objects with an upload_state_id of 3? I get the feeling I'm going to have to write class methods, but I'm a bit stuck on where to start.

• PHP can't connect to localhost XMPP server on port 5222

  - by Ben Werdmuller

  I've set up an ejabberd install locally on my Windows box, where I also have Apache, PHP and MySQL. I've also confirmed that it works great using Digsby, and have kicked the tires a bit by creating some users, sending some messages, etc. All good. However, PHP can't open a stream using stream_socket_client to port 5222. Even at its simplest level: stream_socket_client("tcp://localhost:5222", $errno, $errstr, 30, STREAM_CLIENT_CONNECT); Returns a timeout error. However, again, connecting with an IM client to localhost on port 5222 works fine. Any ideas? I'm stuck!

• How to connect 2 virtual hosts running on the same machine?

  - by Gabrielle

  I have 2 virtual hosts running on my Windows XP laptop. One is Ubuntu running inside vmware player. The other is MS virtual PC (so I can test with IE6 ). The Ubuntu virtual host is running my web application with apache. I can point my browser on my laptop at the Ubuntu IP and view my web app. I read this post http://stackoverflow.com/questions/197792/how-to-connect-to-host-machine-from-within-virtual-pc-image and was able to get my Virtual PC to ping my physical machine using the loopback adapter. But I'm stuck on getting my Virtual PC to see my web application running in the Ubuntu vmware player host. I appreciate any suggestions.

• Printing out series of numbers in java

  - by Jay

  hi guys i am just doing some reading for myself to learn java and came across this problem and is currently stuck. i need to print out series of number based on the input given by the user. for example, if input = 5, the output should be as follows @1@22@333@4444@55555 import java.util.*; public class ex5{ public static void main(String[] args){ Scanner kb = new Scanner(System.in); System.out.println("Please type a #: "); int input = kb.nextInt(); for(int i=0;i<input;i++){ if(input==1){ System.out.print("@1"); } if(input==2){ System.out.print("@1@22"); } } } } this doesnt seem to be working because this is the output i get Please type a #: 2 @1@22@1@22 im not sure what to put inside the for loop right now and i dont think i am using the for loop here very well either... any help guys?

• generate Grid from template

  - by theXs

  Howdy, I've got another question regarding phone 7... I want to generate a couple of Grids in a stackpanel - since they all have the same layout I thought it would be a great idea to use DataTemplates ... But then I found that the GRID Object has no "DataTemplate" Property and now I'm kinda stuck ... the template which I use is the following: <DataTemplate x:Key="Speise"> <Grid> <TextBlock Height="36" Margin="8,43,104,0" TextWrapping="Wrap" Text="TextBlock" VerticalAlignment="Top"/> <TextBlock HorizontalAlignment="Right" Height="36" Margin="0,44,8,0" TextWrapping="Wrap" Text="TextBlock" VerticalAlignment="Top" Width="92"/> </Grid> </DataTemplate> The way I now thought of creating my objects is: Grid blubber = (Grid)this.Resources["Speise"]; But that is not working ... I think it's again a really short thing, but I have no clue of how to google for it :(

• need help on php if statement

  - by user225269

  <?php if (!isset($_SESSION['loginAdmin']) || ($_SESSION['loginAdmin'] == '')) { header ("Location: loginam.php"); } else { include('head2.php'); } if (!isset($_SESSION['login']) || ($_SESSION['login'] == '')) { header ("Location: login.php"); } else { include('head3.php'); } ?> I'm really stuck at this problem. What I want to do is to be able to redirect the user to another page base on the information entered. My problem is: if this statement is true: else { include('head3.php'); } This one would also be true: if (!isset($_SESSION['loginAdmin']) || ($_SESSION['loginAdmin'] == '')) { header ("Location: loginam.php"); } Leading me to the login page whether I'm admin or just ordinary user. Is it possible two separate the two if statements so that if this is true: else { include('head3.php'); } Then this statement shouldn't get in the way and redirect me back to the login page: if (!isset($_SESSION['loginAdmin']) || ($_SESSION['loginAdmin'] == '')) { header ("Location: loginam.php"); }

• Better Alternative to Telerik Draggable Panel ?

  - by user284523

  When putting a video in a Telerik Draggable Panel, when dragging the panel, on Firefox the video restart all over again because DOM is reconstructed. They don't seem to have an answer to this. Also we can't seem to be able to control the z-index as it doesn't take into account: when moving the panel over other telerik controls, the video slips under. So any other draggable panel that wouldn't have these annoyances ? Telerik doesn't seem to give any answer so we're afraid we're stuck and we cannot afford to wait longer. Currently think about using Yahoo UI.

• A datastructure for Robotic Sort

  - by amit.codename13

  I am trying to solve this problem : https://www.spoj.pl/problems/CERC07S/ I have identified that i need a datastructure in which reversing operations have lesser time complexity. I tried to create one using a doubly linked list, in which (i thought) reversing can be done in O(1) by just changing a value associated with the starting and ending node which indicates the direction of traversing the list. I tried to implement it but got stuck. Maybe the approach is wrong! Are trees applicable here? If yes, how? Any ideas or links are appreciated? Thanks in advance.

• Android Animate Rotate

  - by oriharel

  I did some digging in Android code, and saw the use of in the indeterminate progress bar. after trying to create my own drawable with this tag: <animated-rotate xmlns:android="http://schemas.android.com/apk/res/android" android:drawable="@drawable/spinner_pia" android:pivotX="50%" android:pivotY="50%" android:framesCount="12" android:frameDuration="100" /> I get an error: "No resource identifier found for attribute 'frameDuration' in package 'android'" - which means that frameDuration is a private attribute. Is there a way to use this "animate-rotate" feature? My task is to replace the system's default indeterminate progress bar. I'd like to do it with as little code as possible (just change few attributes if possible). Using the ProgressBar view, setting: android:indeterminateOnly="true" android:indeterminateBehavior="cycle" android:indeterminateDuration="3500" android:indeterminateDrawable="@drawable/pia_sivuvator" and point "@drawable/pia_sivuvator" to that object would've make my task as elegant as they come but I'm stuck on those private attributes. help?

• How to give a timeout to an FTP connection

  - by dierre

  The story behind: Old script written in ruby 1.8.6 that opens a connection to a ftp and download a configuration file. For a specific client with a windows ftp server the script just hangs. The log stops writing after it opens the connection to the ftp. It's an old script, it's in ruby and I'm not an expert on it. What I tried: So I tried this implementation of a timeout to check if an ftp connection hangs out with this code Timeout::timeout(5) { ftp = Net::FTP.new(host,pass,host) } The problem is that this isn't working. My guess is that the interpreter stops on opening the connection and the timeout doesn't kill the connection because the interpreter is stuck. Is it possible that that's the problem? Could you tell me if there is maybe an alternative solution or if I'm doing something wrong?

• Support-function in the GJK-algorithm.

  - by Marcus Johansson

  I am trying to implement the GJK-algorithm but I got stuck instantly. The problem is to implement the Support-function that isn't O(n^2). As it is now I'm computing the complete Minkowski difference, and then there is really no point in doing the GJK-algorithm. (or is it?) What I mean by Support-function is the function that returns the point in the Minkowski difference that is furthest away in a specified direction. I assume this shouldn't be O(n^2) as it is in my current implementation.

  Hi, Is there any reason why this loop is getting stuck? I can't quite get my head around it: var i:Number = -1; do { i = Math.round(Math.random() * _totalQuestions); } while(_usedQuestions.indexOf(i)); Where _usedQuestions is an array of numbers. This array starts empty. Thanks! Edit: I want the loop to end if i is NOT found in the array.. this way I know the question I have selected has not previously been asked.

• Send javax.mail.internet.MimeMessage to a recipient with non-ASCII name?

  - by phyzome

  I am writing a piece of Java code that needs to send mail to users with non-ASCII names. I have figured out how to use UTF-8 for the body, subject line, and generic headers, but I am still stuck on the recipients. Here's what I'd like in the "To:" field: "????????????" <[email protected]>. This lives (for our purposes today) in a String called recip. msg.addRecipients(MimeMessage.RecipientType.TO, recip) gives "?????S]" <[email protected]> msg.addHeader("To", MimeUtility.encodeText(recip, "utf-8", "B")) throws AddressException: Local address contains control or whitespace in string ``=?utf-8?B?IuOCpuOCo+OCreODmuODh+OCo+OCouOBq+OCiOOBhuOBk+OBnSIgPA==?= =?utf-8?B?Zm9vQGV4YW1wbGUuY29tPg==?='' How the heck am I supposed to send this message?

• Pylons and Pisa (xhtml2pdf): blank page in IE

  - by Utaal

  I'm using pylons to serve a dynamically generated pdf document for reporting: my approach works in firefox & chrome (it displays the pdf inline if the plugin is available or otherwise downloads it) but IE (7 & 8) only show a blank page and doesn't prompt for download. IE correctly shows PDFs generated by other websites, though. Don't know if it matters but the page is accessed through HTTPS. My controller does the following: renders the source page through mako converts the html to pdf using pisa adds these headers to the response: Content-type: application/pdf and Content-disposition: inline; filename=file.pdf Do you have any suggestion? I seem to be stuck and cannot think of anything else to try.

• Installing XAMPP in Amazon EC2

  - by Woho87

  Hi! Can someone explain to me(not a rocket scientist) all the steps for installing XAMPP for a EC2 instance running Linux? And yes I have look the entire web and found nothing, except this "Deploying a lamp stack" and this "Starting Amazon EC2 with Mac OS X". I found the latter one more useful, but as a said I'm not a rocket scientist. I got stuck in to the latter link where I should edit the file .bash_profile with a text editor. I tried the "vi" in SSH, but why can't I open it on textEditor included in all Macs? Is there any easier way to setting up a XAMPP server for a linux server in EC2?

• disabling transactional fixtures in Rspec has no effect

  - by Dia

  Due to a legacy database I'm using, I'm stuck with MySQL using MyISAM, which means my tables don't support transactions. This is causing the tests to fail, since table data generated (I'm using factory_girl for fixtures) by the tests are not reverted for each scenario. I discovered that Rspec exposes the config.use_transactional_fixtures config setting in spec_helper.rb. which is set to true by default. When I set it to false, I don't see any effect on my tests; they still fail due to duplicate records. Isn't that setting supposed to automatically unroll any changes made to the DB? Or am I supposed to do that manually?

• Access the internal phonebook

  - by L0rdAli3n

  For more than two days now, I'm trying to grab a list of all contacts, from the internal phonebook (no facebook-, gmail- or twittercontacts) with their family- and givenname. I managed to get a list with all contacts, socialcontacts included. So I looked at the account_type and saw that on my HTC Desire they were all "com.htc.android.pcsc" and I was like "Great, I just have to filter the whole list". But then all people with non-htc android cellphones would be unable to use my app, if I would hardcode this filter. Next idea was to let the user choose which account he wants to use, but unfortunately the "com.htc.android.pcsc" didn't appear in the list I got from the AccountManager?!? So my question is: Is there any standardized way to access the internal phonebook? I'm really stuck with that and any hint is highly appreciated!
