• gem install of mongrel

  - by atlantis

  I initiated myself into rails development yesterday. I installed ruby 1.9.1 , rubygems and rails. Running 'gem install mongrel' worked fine and ostensibly installed mongrel too. I am slightly puzzled because script/server starts webrick by default 'which mongrel' returns nothing 'locate mongrel' returns lots of entries like . /Developer/SDKs/MacOSX10.5.sdk/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/mongrel-1.0.1 /Developer/SDKs/MacOSX10.5.sdk/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/mongrel-1.0.1/lib /Developer/SDKs/MacOSX10.5.sdk/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/mongrel-1.0.1/lib/mongrel . . . /usr/local/bin/mongrel_rails /usr/local/lib/ruby/gems/1.9.1/cache/mongrel-1.1.5.gem /usr/local/lib/ruby/gems/1.9.1/doc/actionpack-2.3.2/rdoc/files/lib/action_controller/vendor/rack-1_0/rack/handler/evented_mongrel_rb.html /usr/local/lib/ruby/gems/1.9.1/doc/actionpack-2.3.2/rdoc/files/lib/action_controller/vendor/rack-1_0/rack/handler/mongrel_rb.html /usr/local/lib/ruby/gems/1.9.1/doc/actionpack-2.3.2/rdoc/files/lib/action_controller/vendor/rack-1_0/rack/handler/swiftiplied_mongrel_rb.html /usr/local/lib/ruby/gems/1.9.1/gems/actionpack-2.3.2/lib/action_controller/vendor/rack-1.0/rack/handler/evented_mongrel.rb /usr/local/lib/ruby/gems/1.9.1/gems/actionpack-2.3.2/lib/action_controller/vendor/rack-1.0/rack/handler/mongrel.rb /usr/local/lib/ruby/gems/1.9.1/gems/actionpack-2.3.2/lib/action_controller/vendor/rack-1.0/rack/handler/swiftiplied_mongrel.rb /usr/local/lib/ruby/gems/1.9.1/gems/mongrel-1.1.5 . . .

• UIViewController not oreintating. Methods not called

  - by capple

  Greetings, This question does seem to be an ongoing saga in the world of iphone SDK... so heres my contribution... Had two separate projects from the same template... one semi-works, the other not at all... Please let me explain my steps... used this basic GL ES template //iphonedevelopment.blogspot.com/2008/12/opengl-project-template-for-xcode.html had to sort out some of the 'Release' configuration but otherwises has eveything I need to add orientation to a GL ES project. One my first project, did my stuff, then added these methods.... -(BOOL)shouldAutoRotateToInterfaceOrientation ..... -(void)willRotateToInterfaceOrientation .... -(void)didRotateFromInterfaceOrientation .... -(void)willAnimateRotationToInterfaceOrientation .... And understand what they do (or are trying to do in my case), the (BOOL)should... gets called once when the view controller is created, and returns 'YES'. But after that none of the other methods are called! So I started from scratch with a blank template (GL ES one from above)...and added minimum to support auto rotation. But this time none of the methods get called! So I investigated .... //developer.apple.com/iphone/library/qa/qa2010/qa1688.html as it said, I added the GLViewController.view first, then added the GLview as subviews of the application delegate. Nothing! Then found this //www.iphonedevsdk.com/forum/iphone-sdk-development/44993-how-determine-ipad-launch-orientation.html which states to enable orientation notifications [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications]; and then subsequently disable them in the view controller... makes sense...did it, nothing... I think the notifications might be on by default though, since I didn't need to enable them in the first project, yet it still try to verify a orientation (i.e (BOOL)shouldAutoRotate... )... If any one could help me out it would be greatly appreciated as this issue is driving me insane. Thanks in advance. The code can be found here ... http://rapidshare.com/files/392053688/autoRotation.zip N.B These projects avoid nib/xib resources, would like to keep it that way if possible. P.S iPad device not out where I am so I cannot test on a device yet. Would be nice for it to work on the simulator.

• ETag in Spring (ShallowEtagHeaderFilter)

  - by niklassaers

  Hi guys, I've followed http://static.springsource.org/spring/docs/3.0.2.RELEASE/spring-framework-reference/html/mvc.html#mvc-etag and put ShallowEtagHeaderFilter in my web.xml like this: <filter> <filter-name>etagFilter</filter-name> <filter-class>org.springframework.web.filter.ShallowEtagHeaderFilter</filter-class> </filter> <filter-mapping> <filter-name>etagFilter</filter-name> <servlet-name>myServlet</servlet-name> <!-- I've even tried <url-pattern>/*</url-pattern> --> </filter-mapping> But whenever I load my pages, I don't get any etag headers in my response. Any suggestions as to what might be going on? Is there any kind of ordering my filters should have? (I'm also using OpenSessionInViewFilter and DelegatingFilterProxy Cheers Nik

• jQuery .ajax method in IE7 & IE6 not working but working fine in Firefox

  - by RyanP13

  This relates to my previous post: http://stackoverflow.com/questions/2318696/jquery-load-method-causing-page-refresh-ajax I changed my implmentation to use the .ajax method instead of .load and it works fine in Firefox but not in IE7 or IE6: $('ul#coverTabs > li > a').live('click', function(event) { // Find href of current tab var $tabValue = $(this).attr('href'); $.ajax({ type: "GET", cache: false, dataType: "html", url: $(this).attr('href'), success: function(data){ $(data).find('.benefitWrap').each(function(){ var $benefitWrap = $(this).html(); $('.benefitWrap').replaceWith($('<div class="benefitWrap">' + $benefitWrap + '</div>')); }); } }); event.preventDefault(); }); This is killing me as it has taken ages to get this far. Any ideas where i am going wrong?

• TinyMce + Ajax File Manager + Codeigniter = Little Problem

  - by lucha libre

  OK, I'm using the following: TinyMCE, CodeIgniter, and the TinyMCE Ajax File Manager. I can upload correctly and it looks pretty good. However, when I view the HTML (from TinyMCE), this is what I get. <img src="../../../data/page/verde_enfemera.jpg" alt="" /> What I need to be getting is the following: <img src="http://localhost/http/data/page/verde_enfemera.jpg" alt="" /> Can someone help? EDIT: I changed the code in the HTML editor of Tinymce, then I saved it. When I re-opened it, the code was reverted back to the original "../.../../data", etc. please, help, someone.

• convert.php does not run in a screen session

  - by Tobias

  I am trying to convert a big forum. At the moment I have to do this via ssh and start convert.php with "php5 -f convert.php -- $OPTIONS". But my internet connection is a bit buggy and so it is often killed. If i start the above working command in a screen session it does not work. Instead php gives me the HTML code of the "convert.php" back. head of the page: X-Powered-By: PHP/5.2.12 Set-Cookie: PHPSESSID=6bc4370b2d8d40ff8c3ab23672ff4135; path=/ Expires: Thu, 19 Nov 1981 08:52:00 GMT Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0 Pragma: no-cache Content-type: text/html Does it has something to do with the Sessions? But why does it work on the same ssh-connection without screen?

• PHP page load seems to be requesting itself and misinterpreting the result

  - by Regis Frey

  I'm working on a messy PHP page by another developer and I was analyzing the resource view in the Webkit developer tools and noticed that the page (index.php) makes an HTTP requests for itself and then interprets the results as an image despite it being sent with the text/html header. Because of this it throws the warning: Resource interpreted as image but transferred with MIME type text/html. Looking at the time graph the call comes after the <head> because it has already requested images for the body. Sometimes there are even two 'bad' requests. Can anyone explain what might be happening and/or suggest how to fix this? Could these be related to PHP includes?

• How can I highlight empty fields in ASP.NET MVC 2 before model binding has occurred?

  - by Richard Poole

  I'm trying to highlight certain form fields (let's call them important fields) when they're empty. In essence, they should behave a bit like required fields, but they should be highlighted if they are empty when the user first GETs the form, before POST & model validation has occurred. The user can also ignore the warnings and submit the form when these fields are empty (i.e. empty important fields won't cause ModelState.IsValid to be false). Ideally it needs to work server-side (empty important fields are highlighted with warning message on GET) and client-side (highlighted if empty when losing focus). I've thought of a few ways of doing this, but I'm hoping some bright spark can come up with a nice elegant solution... Just use a CSS class to flag important fields Update every view/template to render important fields with an important CSS class. Write some jQuery to highlight empty important fields when the DOM is ready and hook their blur events so highlights & warning messages can be shown/hidden as appropriate. Pros: Quick and easy. Cons: Unnecessary duplication of importance flags and warning messages across views & templates. Clients with JavaScript disabled will never see highlights/warnings. Custom data annotation and client-side validator Create classes similar to RequiredAttribute, RequiredAttributeAdapter and ModelClientValidationRequiredRule, and register the adapter with DataAnnotationsModelValidatorProvider.RegisterAdapter. Create a client-side validator like this that responds to the blur event. Pros: Data annotation follows DRY principle (Html.ValidationMessageFor<T> picks up field importance and warning message from attribute, no duplication). Cons: Must call TryValidateModel from GET actions to ensure empty fields are decorated. Not technically validation (client- & server-side rules don't match) so it's at the mercy of framework changes. Clients with JavaScript disabled will never see highlights/warnings. Clone the entire validation framework It strikes me that I'm trying to achieve exactly the same thing as validation but with warnings rather than errors. It needs to run before model binding (and therefore validation) has occurred. Perhaps it's worth designing a similar framework with annotations like Required, RegularExpression, StringLength, etc. that somehow cause Html.TextBoxFor<T> etc. to render the warning CSS class and Html.ValidationMessageFor<T> to emit the warning message and JSON needed to enable client-side blur checks. Pros: Sounds like something MVC 2 could do with out of the box. Cons: Way too much effort for my current requirement! I'm swaying towards option 1. Can anyone think of a better solution?

• Create signed urls for CloudFront with Ruby

• Get jQuery post redirect response

  - by Wickethewok

  I've written some HTML/Javascript that sits on a third-party server for security reasons. This page performs a javascript post to another page on the same site. However, instead of responding with useful data, it instead wants to perform a redirect (if you would post via a normal HTML form to this page, it would redirect your browser). How can I process this process? I basically want to be able to extract the url's query parameters that it is trying to redirect with (and then put this link into a hidden form field). Here is my basic ajax post... $.ajax({ url: '/someurl/idontcontrol', data: serialized_form_data, async: false, type: 'POST', success: function(data, textStatus) { $('#redirect_link').val(WHAT_DO_I_PUT_HERE); } }); Note that the URL I am posting to is not one that I control, so I have no power over what it returns. Thanks!

• How to detect if a page is an RSS or ATOM feed

  - by Pepper

  Hello, I'm currently building a new online Feed Reader in PHP. One of the features i'm working on is feed auto-discovery. If a user enters a website URL, the script will detect that its not a feed and look for the real feed URL by parsing the HTML for the proper tag. The problem is, the way im currently detecting if the URL is a feed or a website only works part of the time, and I know it can't be the best solution. Right now im taking the CURL response and running it through simplexml_load_string, if it can't parse it I treat it as a website. Here is the code. $xml = @simplexml_load_string( $site_found['content'] ); if( !$xml ) // this is a website, not a feed { // handle website } else { // parse feed } Obviously, this isn't ideal. Also, when it runs into an HTML website that it can parse, it thinks its a feed. Any suggestions on a good way of detecting the difference between a feed or non-feed in PHP? Thanks, Pepper http://feedingo.com

• Dynamic content in ExtJS Window

  - by Ozaki

  TLDR I want to add some dynamic content into an Ext-JS window / popup. Currently I have tried assigning this content to a div and pulling on the innerhtml of that div like: new Ext.Window({ height: 50, width: 160, x: 0, y: 30, layout: "fit", html: document.getElementById('output').innerHTML; }).show(); Am using jquery & getjson to get the dynamic data. But that does nothing at all. Has anyone done something similar before? Can I give the html of the window an id and use it like an element?

• Use ASP.Net server control code generation from .ashx

  - by Matt Dawdy

  I'm trying to take an existing bunch of code that was previously on a full .aspx page, and do the same stuff in a .ashx handler. The code created an HtmlTable object, added rows and cells to those rows, then added that html table the .aspx's controls collection, then added it to a div that was already on the page. I am trying to keep the code in tact but instead of putting the control into a div, actually generate the html and I'll return that in a big chunk of text that can be called via AJAX client-side. HtmlTable errors out when I try to use the InnerHtml property (says it isn't supported), and when I try RenderControl, after making first a TextWriter and next an HtmlTextWriter object, I get the error that Page cannot be null. Has anyone done this before? Any suggestions?

• highlighting non-ascii text

  - by non-techie

  As a non-techie, I would really appreciate your help on this. I have some files (html) that need to be in pure ascii form to be properly processed. Since these files are produced by humans, every so often non-ascii characters sneak in. Often it is a stray " (curled variety) or something similar that is difficult to find and need to be removed. I have found text editors (eg. textmate) that can strip out all non-ascii characters, but I need to find one that can highlight where they are, rather than remove them (as I need to remove them from the source and not the html file). I hope this makes sense and appreciate any assistance you can provide. Thanks!

• Want to load jquery dialog from a different web-page

  - by Jake

  I'm a bit of a n00b with jquery so this one is probably an RTFM question: I'm writing an application to create a somewhat complex record for my client. Building the record requires doing a couple of server side searches inside a dialog. Right now I have everything framed up in 1 file (asp.net) and it's ok. But I can see as I add the business logic and the communication with the server this is going to get really ugly. I'm alreay putting most of the javascript in external files, but I'd like to move the HTML for the dialogs out too. How do I get the jquery dialog method to load the dialog body from the html files? Something like: getDialogHTML(dialogHolderDiv); <---magic goes here var dialogOptions = { ... }; $("#"+dialogHolderDiv).dialog(dialogOptions); $("#"+dialogHolderDiv).dialog('open'); any help will be apperciated .

• innerHTML removes attribute quotes in Internet Explorer

  - by Augustus

  When you get the innerHTML of a DOM node in IE, if there are no spaces in an attribute value, IE will remove the quotes around it, as demonstrated below: <html> <head> <title></title> </head> <body> <div id="div1"><div id="div2"></div></div> <script type="text/javascript"> alert(document.getElementById("div1").innerHTML); </script> </body> </html> In IE, the alert will read: <DIV id=div2></DIV> This is a problem, because I am passing this on to a processor that requires valid XHTML, and all attribute values must be quoted. Does anyone know of an easy way to work around this behavior in IE?

• How can I block based on URL (from address bar) in a safari extension

  - by PerilousApricot

  I'm trying to write an extension that will block access to (configurable) list of URLs if they are accessed more than N times per hour. From what I understand, I need to have a start script pass a "should I load this" message to a global HTML page (who can access the settings object to get the list of URLs), who will give a thumbs up/thumbs down message back to the start script to deny/allow loading. That works out fine for me, but when I use the usual beforeLoad/canLoad handlers, I get messages for all the sub-items that need to be loaded (images/etc..), which screws up the #accesses/hour limit I'm trying to make. Is there a way to synchronously pass messages back and forth between the two sandboxes so I can tell the global HTML page, "this is the URL in the window bar and the timestamp for when this request came in", so I can limit duplicate requests? Thanks!

• Smarty debug mode not displaying included templates.

  - by Kyle Sevenoaks

  On www.euroworker.no/order I have set Smarty's debug mode on with {debug output=html} in the header, so it will debug every page. But it says: Smarty Debug Console included templates & config files (load time in seconds): no templates included And after a list of template variables, {$cart} Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 561962 bytes) in /home/euroworkerno/www/library/smarty/libs/plugins/modifier.debug_print_var.php on line 30 It also doesn't display a list of templates for any url.. This is strange, can anyone point me to why it won't display the lit of .tpls? I need to find some HTML comments that someone has left in to rid IE of a display bug. Thanks.

• Opening pop up in Joomla

  - by user258100

  I am trying to have people be able to open HTML widgets by clicking on a button in my Joomla page. All the widgets are different sizes. The code is entered as HTML in Jumi. Currently I have the action set to: "On click open in new window without browser navigation." The problem is this this always opens in a full screen size with the widget showing up in a corner. How do I control the size of this new window for each widget? Thanks

• How do I use Python's itertools.groupby()?

  - by James Sulak

  I haven't been able to find an understandable explanation of how to actually use Python's itertools.groupby() function. What I'm trying to do is this: take a list - in this case, the children of an objectified lxml element - divide it into groups based on some criteria, and then later iterate over each of these groups separately. I've reviewed the documentation (http://docs.python.org/lib/itertools-functions.html), and the examples, (http://docs.python.org/lib/itertools-example.html), but I've had trouble trying to apply them beyond a simple list of numbers. So, how do I use of itertools.groupby()? Is there another technique I should be using? Pointers to good "prerequisite" reading would also be appreciated.

• $.ajax post to PHP mail() using jQuery doesn't work

  Hey, I looked around on SO and Google, but couldn't really find a solution. Could someone please explain to me why this doesn't work? This is my first time using AJAX to submit a form. $.ajax({ type: "POST", url: "<?php bloginfo('template_url'); ?>/email.php", data: dataString, success: function() { $('#contact_form').html("<div id='message'></div>"); $('#message').html("<h2>Contact Form Submitted!</h2>") .append("<p>We will be in touch soon.</p>") .hide() .fadeIn(1500, function() { $('#message').append("<img id='checkmark' src='images/check.png' />"); }); } }); and <?php $name=$_POST['name']; $email=$_POST['email']; $phone=$_POST['phone']; $subject=$_POST['subject']; $message=$_POST['message']; $quote=$_POST['quote']; $to="[email protected]"; $body="<p>From: ".$name." <".$email."><br />"; $body.="Phone: ".$phone."<br />"; $body.="Project: ".$subject."<br />"; $body.="Quote: ".$quote."</p>"; $body.="<p>Message:<br /> ".$message."</p>"; $headers = "MIME-Version: 1.0" .

• How to keep views free of authorization logic in mvc?

  - by David Lay

  I have a view to display a list of items. The user can edit, delete or create new items, but according to their authorizations they may or may not be allowed to do some of this actions. I have the requirement to display only the actions which the current user is allowed to do, but I don't want to clutter the views with authorization if-else's Despise of being a very common requirement, I can't find a real satisfactory way of doing it. My best approach so far is to provide an overload to the Html.ActionLink extension method that takes the permission to ask for, but there are going to be more complex scenarios, like hiding entire blocks of html or switching a textbox for a label+hidden. Is there a better way to do this?
