  • Rails Controller Tests for Captcha using Shoulda, Factory Girl, Mocha

    - by Siva
    Can someone provide a strategy/code samples/pointers to test Captcha validations + Authlogic using Shoulda, Factory Girl and Mocha? For instance, my UsersController is something like: class UsersController < ApplicationController validates_captcha ... def create ... if captcha_validated? # code to deal with user attributes end ... end In this case, how do you mock/stub using Shoulda / Factory Girl / Mocha to test valid and invalid responses to the Captcha image? Appreciate your help, Siva

  • PHP - static DB class vs DB singleton object

    - by Marco Demaio
    I don't want to create a discussion about singleton better than static or better than global, etc. I read dozens of questions about it on SO, but I couldn't come up with an answer to this SPECIFIC question, so I hope someone could now illuminate me buy answering this question with one (or more) real simple EXAMPLES, and not theoretical discussions. In my app I have the typical DB class needed to perform tasks on DB without having to write everywhere in code mysql_connect/mysql_select_db/mysql... (moreover in future I might decide to use another type of DB engine in place of mySQL so obviously I need a class of abstration). I could write the class either as a static class: class DB { private static $connection = FALSE; //connection to be opened //DB connection values private static $server = NULL; private static $usr = NULL; private static $psw = NULL; private static $name = NULL; public static function init($db_server, $db_usr, $db_psw, $db_name) { //simply stores connections values, withour opening connection } public static function query($query_string) { //performs query over alerady opened connection, if not open, it opens connection 1st } ... } or as a Singletonm class: class DBSingleton { private $inst = NULL; private $connection = FALSE; //connection to be opened //DB connection values private $server = NULL; private $usr = NULL; private $psw = NULL; private $name = NULL; public static function getInstance($db_server, $db_usr, $db_psw, $db_name) { //simply stores connections values, withour opening connection if($inst === NULL) $this->inst = new DBSingleton(); return $this->inst; } private __construct()... public function query($query_string) { //performs query over already opened connection, if connection is not open, it opens connection 1st } ... } Then after in my app if I wanto to query the DB i could do //Performing query using static DB object DB:init(HOST, USR, PSW, DB_NAME); DB::query("SELECT..."); //Performing query using DB singleton $temp = DBSingleton::getInstance(HOST, USR, PSW, DB_NAME); $temp->query("SELECT..."); My simple brain sees Singleton has got the only advantage to avoid declaring as 'static' each method of the class. I'm sure some of you could give me an EXAMPLE of real advantage of singleton in this specific case. Thanks in advance.

  • What does JSLint's "Bad Escapement" mean in this case?

    - by karlthorwald
    I thougth "bad escapement" stands for wrong use escaping with slash. Why does JSLint bring up the message in this function on the 3d line (for...) ? function splitTags(commaSeparated) { var tagArray = commaSeparated.split(','); for (var i=tagArray.length - 1; i>=0; --i ){ tagArray[i] = f.trim(tagArray[i]); } return tagArray; }

  • Datagrid using usercontrol

    - by klawusel
    Hello I am fighting with this problem: I have a usercontrol which contains a textbox and a button (the button calls some functions to set the textbox's text), here is the xaml: <UserControl x:Class="UcSelect" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Name="Control1Name" <Grid x:Name="grid1" MaxHeight="25"> <Grid.ColumnDefinitions> <ColumnDefinition /> <ColumnDefinition Width="25"/> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition Height="25"/> </Grid.RowDefinitions> <TextBox x:Name="txSelect" Text="{Binding UcText, Mode=TwoWay}" /> <Button x:Name="pbSelect" Background="Red" Grid.Column="1" Click="pbSelect_Click">...</Button> </Grid> And here the code behind: Partial Public Class UcSelect Private Shared Sub textChangedCallBack(ByVal [property] As DependencyObject, ByVal args As DependencyPropertyChangedEventArgs) Dim UcSelectBox As UcSelect = DirectCast([property], UcSelect) End Sub Public Property UcText() As String Get Return GetValue(UcTextProperty) End Get Set(ByVal value As String) SetValue(UcTextProperty, value) End Set End Property Public Shared ReadOnly UcTextProperty As DependencyProperty = _ DependencyProperty.Register("UcText", _ GetType(String), GetType(UcSelect), _ New FrameworkPropertyMetadata(String.Empty, FrameworkPropertyMetadataOptions.BindsTwoWayByDefault, New PropertyChangedCallback(AddressOf textChangedCallBack))) Public Sub New() InitializeComponent() grid1.DataContext = Me End Sub Private Sub pbSelect_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) 'just demo UcText = UcText + "!" End Sub End Class The UserControl works fine when used as a single control in this way: <local:UcSelect Grid.Row="1" x:Name="ucSingle1" UcText="{Binding FirstName, Mode=TwoWay}"/> Now I wanted to use the control in a custom datagrid column. As I like to have binding support I choosed to derive from DataGridtextColumn instead of using a DataGridTemplateColumn, here is the derived column class: Public Class DerivedColumn Inherits DataGridTextColumn Protected Overloads Overrides Function GenerateElement(ByVal oCell As DataGridCell, ByVal oDataItem As Object) As FrameworkElement Dim oElement = MyBase.GenerateElement(oCell, oDataItem) Return oElement End Function Protected Overloads Overrides Function GenerateEditingElement(ByVal oCell As DataGridCell, ByVal oDataItem As Object) As FrameworkElement Dim oUc As New UcSelect Dim oBinding As Binding = CType(Me.Binding, Binding) oUc.SetBinding(UcSelect.UcTextProperty, oBinding) Return oUc End Function End Class The column is used in xaml in the following way: <local:DerivedColumn Header="Usercontrol" Binding="{Binding FirstName, Mode=TwoWay}"></local:DerivedColumn> If I start my program all seems to be fine, but changes I make in the custom column are not reflected in the object (property "FirstName"), the changes are simply rolled back when leaving the cell. I think there must be something wrong with my GenerateEditingElement code, but have no idea ... Any Help would really be appreciated Regards Klaus

  • JQuery timer plugin on ASP.NET MVC Page button click

    - by Rita
    Hi I have an ASP.NET MVC Page with a button called "Start Live Meeting". When the User clicks on this button, it calls a controller method called "StartLiveMeeting" that returns a string. If the controller returns empty string, then i want the Timer to call the Controller method until it returns the string. I am using jquery.timer.js plugin ( http://plugins.jquery.com/files/jquery.timers-1.2.js.txt ) On the button click, the controller method is being called. But Timer is not initiating. I have specified 5sec to call the controller method. I appreciate your responses. Code on ASPX Page: //When "Start Meeting" button is clicked, if it doesn’t return empty string, Display that text and Stop Timer. Else call the Timer in every 5 sec and call the StartLiveMeeting Controller method. $("#btnStartMeeting").click(function() { var lM = loadLiveMeeting(); if (lM == "") { $("#btnStartMeeting").oneTime("5s", function() { }); } else { $("#btnStartMeeting").stopTime("hide"); } return false; }); function loadLiveMeeting() { $("#divConnectToLive").load('<%= Url.Action("StartLiveMeeting") %>', {}, function(responseText, status) { return responseText; }); } <asp:Content ID="Content2" ContentPlaceHolderID="cphMain" runat="server"> <div id="divStartMeetingButton"><input id="btnStartMeeting" type="submit" value="Start Meeting" /> </div> <div id = "divConnectToLive"> <div id="loading" style="visibility:hidden"> <img src="../../img/MedInfo/ajax_Connecting.gif" alt="Loading..." /> </div> </div> Controller Method: [HttpPost] public string StartLiveMeeting() { int intCM_Id = ((CustomerMaster)Session["CurrentUser"]).CM_Id ; var activeMeetingReq = (from m in miEntity.MeetingRequest where m.CustomerMaster.CM_Id == intCM_Id && m.Active == true select m); if (activeMeetingReq.Count() > 0) { MeetingRequest meetingReq = activeMeetingReq.First(); return "<a href='" + meetingReq.URI + "'>" + "Connect to Live Meeting</a>"; } else { return ""; } }

  • Icons on CMFCOutlookBar

    - by steve-weeks
    I'm using CMFCOutlookBar from the Feature Pack, and I'm trying to put an icon on the "button" of the tabbed pane - the thing that slides up and down in the bar, when you select a pane. The pane API includes a "SetIcon" function, but this doesn't do anything as far as I can tell. Neither does the "SetTabHicon" function of the bar. Does anyone know how to do this?

  • Unix substr in shell script?

    - by KnockKnockWhosThere
    I have a string like sample.txt.pgp and I want to return sample.txt in a shell script. Is there a substr function? Like, if I did substr('sample.txt.pgp', -4, 0), is it supposed to return sample.txt? Right now it isn't, so I'm wondering if I have the syntax wrong, or maybe substr isn't a function?

  • Search Complexity of a Hashtable within a Hashtable?

    - by spacker_lechuck
    Say we have a hashtable of size m, and at each bucket we store a hashtable of size p. What would the worst case/average case search complexity be? I am inclined to say that since computing a hash function is still atomic, the only worst case scenario is if the value is at the end of the linked list in the hashtable of size p, so O(n)? I have no idea how to calculate the average case for this scenario and would appreciate any pointers!

  • Comparing two large sets of attributes

    - by andyashton
    Suppose you have a Django view that has two functions: The first function renders some XML using a XSLT stylesheet and produces a div with 1000 subelements like this: <div id="myText"> <p id="p1"><a class="note-p1" href="#" style="display:none" target="bot">?</a></strong>Lorem ipsum</p> <p id="p2"><a class="note-p2" href="#" style="display:none" target="bot">?</a></strong>Foo bar</p> <p id="p3"><a class="note-p3" href="#" style="display:none" target="bot">?</a></strong>Chocolate peanut butter</p> (etc for 1000 lines) <p id="p1000"><a class="note-p1000" href="#" style="display:none" target="bot">?</a></strong>Go Yankees!</p> </div> The second function renders another XML document using another stylesheet to produce a div like this: <div id="myNotes"> <p id="n1"><cite class="note-p1"><sup>1</sup><span>Trololo</span></cite></p> <p id="n2"><cite class="note-p1"><sup>2</sup><span>Trololo</span></cite></p> <p id="n3"><cite class="note-p2"><sup>3</sup><span>lololo</span></cite></p> (etc for n lines) <p id="n"><cite class="note-p885"><sup>n</sup><span>lololo</span></cite></p> </div> I need to see which elements in #myText have classes that match elements in #myNotes, and display them. I can do this using the following jQuery: $('#myText').find('a').each(function() { var $anchor = $(this); $('#myNotes').find('cite').each(function() { if($(this).attr('class') == $anchor.attr('class')) { $anchor.show(); }); }); However this is incredibly slow and inefficient for a large number of comparisons. What is the fastest/most efficient way to do this - is there a jQuery/js method that is reasonable for a large number of items? Or do I need to reengineer the Django code to do the work before passing it to the template?

  • jQuery: How can I check if a block in my document is inside the viewport or outside of it?

    - by Jannis
    I am basically trying to trigger a function if the footer is inside the viewport. How can I check whether the footer is currently visible in the viewport? I assume I will have to put it into the $(window).scroll() event so that the listener becomes true once the footer becomes visible but what the function should be I just can't figure out. Any help would be much appreciated. Thanks for reading, Jannis

  • How to extend/patch an existing module or package?

    - by nat
    I want to extend some locale-specific features of a python application named OpenERP. All I need is implementing a third party module.function that would be called every time OpenERP calls locale.setlocale() function without changing neither OpenERP nor locale module source code. The only way I can imagine is provide a module named locale.py inside main application package dir, but It seems that is an unpythonic workaround.

  • class composition instead of object composition?

    - by fayer
    I want a class property to be reference to another class, not its object and then use this property to call the class's static methods. class Database { private static $log; public static function addLog($LogClass) { self::$log = $LogClass; } public static function log() { self::$log::write(); // seems not possible to write it like this } } any suggestions how i can accomplish this? cause i have no reason making them objects, i want to use the classes for it.

  • D3.js transition callback on frame

    - by brenjt
    Does anyone know how I could accomplish a per frame callback for a transition with D3. Here is and example of what I am doing currently. link.transition() .duration(duration) .attr("d", diagonal) .each("end",function(e) { if(e.target.id == current) show_tooltip(e.target) }); This currently calls the anonymous function for each element at the end of the animation. I would like to call it for every frame.

  • Correct mapping for SHChangeNotify in JNA

    - by user389658
    This is syntax for SHChangeNotify function from MSDN: void SHChangeNotify( LONG wEventId, UINT uFlags, __in_opt LPCVOID dwItem1, __in_opt LPCVOID dwItem2 ); I've to write its Java counterpart in Java Native Access [JNA], but this declaration seems to be wrong: public interface Shell32 extends com.sun.jna.platform.win32.Shell32 { public Shell32 INSTANCE = (Shell32) Native.loadLibrary(Shell32.class); void SHChangeNotify(long wEventId, int uFlags, Pointer dwItem1, Pointer dwItem2); } I got the following exception: Exception in thread "main" java.lang.UnsatisfiedLinkError: Error looking up function 'SHChangeNotify' Any idea how to write it correctly?

  • Escaping Strings in JavaScript

    - by Steve Harrison
    Hello, Does JavaScript have a built-in function like PHP's addslashes (or addcslashes) function to add backslashes to characters that need escaping in a string? For example, this: This is a demo string with 'single-quotes' and "double-quotes". ...would become: This is a demo string with \'single-quotes\' and \"double-quotes\". Thanks, Steve

  • jQuery hide ul header when all entries are deleted...

    - by Scott
    I'm a noob with jQuery...and I hope I've explained this well enough; I have a <ul> header that appears when I've added an entry to a dynamically created list using $.post. Each entry added has a delete/edit button associated with it. Header is this: <ul class="header"> <li>Month</li> <li>Year</li> <li>Cottage</li> </ul> My dynamic list that is created: <ul class="addedItems"> <li>Month</li> <li>Year</li> <li>Cottage</li> <li><span class="edit">edit</span></li> <li><span class="del">delete</span></li> </ul> This all looks like this: Month Year Cottage <--this appears after I've added an entry -------------------------------- and I want it to stick around unless all items are deleted. Dec 1990 Fir edit/delete <--entries Jan 2000 Willow edit/delete My question is: Is there some kind of conditional that I can use with jQuery to hide the class="header" if all the items are deleted? I've read up on conditional statements like is and not with jq but I'm not really understanding how they work. All of the items in class="addedItems" is stored in data produced by JSON. This is the delete function: $(".del").live("click", function(){ var del = this; var thisVal = $(del).val(); $.post("delete.php", { dirID : thisVal }, function(data){ if(confirm("Are you sure you want to DELETE this entry?") == true) { if(data.success) { //hide the class="header" here somwhere?? $(del).parents(".addedItems").hide(); } else if(data.error) { // throw error if item does not delete } } }, "json"); return false; }); //end of .del function Here is the delete.php <?php if($_POST) { $data['delID'] = $_POST['dirID']; $query = "DELETE from //tablename WHERE dirID = '{$data['delID']}' LIMIT 1"; $result = $db->query($query); if($result) { $data['success'] = true; $data['message'] = "Entry was successfully removed."; } else { $data['error'] = true; $data['message'] = "Item could not be deleted."; } echo json_encode($data); } ?>
