  • Problems running Ruby on Rails apps on shared hosted server

    - by Evgeny
    I have problems installing any Ruby On Rails app on my shared hosted server. Mongrel shows html as plain text for all pages. The problem occurs for any app, even if I create a test empty app and add a scaffolded view without changing anything. It appears that the Mongrel crashes when trying to put cookies to the response header. The HTTP header looks incomplete, the Content-type and other parameters are missing: curl 127.0.0.1:12002/users -I HTTP/1.1 200 OK Connection: close Date: Wed, 26 May 2010 09:46:50 GMT Content-Length: 0 Here is the output from mongrel.log Error calling Dispatcher.dispatch #<NoMethodError: You have a nil object when you didn't expect it! You might have expected an instance of ActiveRecord::Base. The error occurred while evaluating nil.[]> /usr/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/../lib/mongrel/cgi.rb:108:in `send_cookies' /usr/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/../lib/mongrel/cgi.rb:136:in `out' /usr/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/../lib/mongrel/http_response.rb:65:in `start' ruby 1.8.7 rails 2.3.8 mongrel 1.1.5 Here is the link to the test page. Has anyone seen anything like this?

  • Multiple HTML lines with jquery tooltip plugin

    - by dafi
    I'm using the plugin http://bassistance.de/jquery-plugins/jquery-plugin-tooltip/ to create tooltips with JQuery but I can't created tooltips containing 3 (or more) lines of HTML code. I need to render as tooltip the content shown below (obviously the content is generated dynamically an this it only a proof of concept) <p>Line1</p> <p>Line2 <span style="...">blah blah</span></p> <p>Line3</p> The showBody property seems applicable only to title attributes. Found the problem Apparently jquery.html("...") requires a root tag otherwise generates an empty string. My original code was bodyHandler: function() { return $("<span id='caption'>line1</span>" + "<span id='tags'>line2</span>"); } need to be written with a dummy root tag removed by JQuery bodyHandler: function() { return $( "<root-dummy-tag>" + "<span id='caption'>line1</span>" + "<span id='tags'>line2</span>" + "</root-dummy-tag>" ); }

  • Redraw and flicker issues

    - by AngryHacker
    I have an Outlook style app. So basically I have a sidebar on the left and on the right I have a panel control (pnlMainBody) that hosts content. The content is typically a user control that I add to the panel when user clicks appropriate button in the side bar. The way I add the user control to the panel is as follows: // _pnlEmails is the User Control that I am adding to the panel _pnlEmails = new pnlEmails(); _pnlEmails.Dock = DockStyle.Fill; this.pnlMainBody.Controls.Add(_pnlEmails); Some of the user controls that I add to the main panel are quite complex UI-wise. So when this.pnlMainBody.Controls.Add(_pnlEmails); fires, I see the control appear on the screen, then it resizes itself to fill the body of the panel control. It's quite ugly actually, so I was wondering whether there is a way to not show the resizing until it's actually done resizing? I've tried setting the user control's .Visible to false. I've tried doing .SuspendLayout, all to no avail. Is there a way to do this so the screen transitions are smooth?

  • webcam refreshing image in iframe not working IE

    - by Nix
    I'm trying to show images from this webcam http://regacam.usz.ch/cgi-bin/guestimage.html on an html page by putting an iframe in pointing to another page that has an image tag in it. But it isn't working in IE (I just see a little cross where the image should be), Firefox is ok. Here the page with the image in: <html> <head> <meta http-euqiv="refresh" content="5"> </head> <body> <img src="http://regacam.usz.ch/cgi-bin/faststream.jpg?stream=full&fps=0.01667&rand=295543" width="200" height="150"/> </body> <html> and the iframe: <div id="rightcontainer"> <iframe id="rightframe" src="zurich.html" name="content" frameborder="0"></iframe> </div> I tried a different webcam elsewhere and that works ok in both browsers. Is there something odd about the one in my example? I got the link in src by right-clicking and copying the image location - is that the right way to go about it?

  • JQuery datepicker not working

    - by IniTech
    I'm completely new to JQuery and MVC. I'm working on a pet project that uses both to learn them and I've hit my first snag. I have a date field and I want to add the JQuery datepicker to the UI. Here is what I have done: Added <script src="../../Scripts/jquery-1.3.2.min.js" type="text/javascript"></script> to the site.master Inside my Create.aspx (View), I have <asp:Content ID="Create" ContentPlaceHolderID="MainContent" runat="server"> <h2> Create a Task</h2> <% Html.RenderPartial("TaskForm"); %> </asp:Content> and inside "TaskForm" (a user control) I have: <label for="dDueDate"> Due Date</label> <%= Html.TextBox("dDueDate",(Model.Task.TaskID > 0 ? string.Format("{0:g}",Model.Task.DueDate) : DateTime.Today.ToString("MM/dd/yyyy"))) %> <script type="text/javascript"> $(document).ready(function() { $("#dDueDate").datepicker(); }); </script> As you can see, the above checks to see if a task has an id 0 (we're not creating a new one) if it does, it uses the date on the task, if not it defaults to today. I would expect the datepicker UI element to show up, but instead I get: "Microsoft JScript runtime error: Object doesn't support this property or method" on the $("#dDueDate").datepicker(); Ideas? It is probably a very simple mistake, so don't over-analyze. As I said, this is the first time I've dealt with MVC or JQuery so I'm lost as to where to start.

  • Frameset isn't working in IE

    - by Cameroon
    First of all, why use a frame set in the first place you ask? answer: Because my boss told me. That been said, I have 2 files. Index.html and Head.html. Contents of index.html: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN" "http://www.w3.org/TR/1999/REC-html401-19991224/frameset.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" /> <title>Site Title</title> </head> <frameset rows="122,*" FRAMEBORDER=NO FRAMESPACING=2 BORDER=0> <frame name="t" src="head.html" scrolling="no" marginheight="0" marginwidth="0"> <frame name="b" src="http://www.website.com"> </frameset> <noframes> <p>You have frames turned off on your browser, please turn it on and reload this page.</p> </noframes> </html> Contents of head.html: <div style="border-bottom:2px solid #000;height:120px"> <center>This is the frame head.</center> </div> The code works fine in all browsers except Internet Explorer 7 and 8 (I don't care about 6). Is there anything I am doing wrong, and if not then can the same effect be achieved without frames and if so how?

  • GLOBAL loading inside each single button with Jquery in ajax calls of asp.net mvc

    - by Ricky
    I have the following scenario: I have a button\link with a image inside like this: <button type="submit" id="myButton" class="button"><img src="../../Content/images/check.png" id="defaultImage" /> SaveData!!!</button> We are OK here! Now what I need to do is: I want on the click that the image change for a loading element that is previously loaded in the page like this: <img id="loadingImage" src="../../Content/images/loader.gif" style="display: none;" alt="loading"/> And then when the load complete turn back the old button image, I ended with this code: function loader() { var $button = $('#myButton'); if (btnState == '1') { $button.find('img').hide(); $button.prepend($('#loadingImage')); $('#loadingImage').css({ 'display': 'inherit' }); btnState = '0'; } else { $button.find('img').hide(); $button.prepend($('#defaultImage')); $('#defaultImage').show(); btnState = '1'; } } This does the trick for ONE SINGLE button(since I pass its ID in the function) but, when I have for example a grid with a button on each line, I found inviable when managing a screen with many buttons do this for each of then. The main question is: How can I make this method general for all buttons/links on one specific class in the page? The goal is: Click a button, get the image and change it and stop(can be manual). I just don't wanna have to Hook ALL buttons.

  • Asynchronous Image loading in certain custom UITableViewCells

    - by Dan
    So, I'm sure that this issue has been brought up before, but I haven't quite seen a solution for my specific problem. What I'm doing is loading a group of custom UITableViewCell's that are drawn using Loren Brichter's solution, each cell has some content, an icon (representing the user) that is asynchronously loaded into it, and a few other things. Eventually, I'm hoping to add support for images. Not every cell has an image, so in the creation of the cell, it determines if an image is required to be loaded and drawn into the cell. My problem is that I don't know how I can do that while keeping the image loaded asynchronously - with not every cell having the need to load an image (like needed with the icon) I'm not sure how to keep it in order when an cell is thrown off screen and re-rendered when the user scrolls over it. Each cell draws it content from an NSArray containing a custom object called FeedItem. All I'm really looking for is some sort of solution or idea to help me because right now I am at a loss. Thanks guys, I will appreciate the help.

  • Javascript break breaks Firefox

    - by Maxime
    Hi, I'm working on this Javascript script that works nice in Safari and Chome but for some reason it doesn't work at all in Firefox. I identified the line that caused this: it's "break;". How do I fix this? playListConfig( index ); $("#jquery_jplayer").jPlayer("play"); song_num = myPlayList[index].song_id; if(!o[song_num]) { o[song_num] = 1;} $.get("http://www.ratemysong.net/includes/getnote.php?song_id="+song_num+"&s"+Math.random(), function(data){ if(data == "") { $('#rating ul li a').each(function() { $(this).attr('href', '#'); $(this).css("color","#FFF"); }); $('#rating ul li a').click(function(e) { ++o[song_num]; if(o[song_num]==2) { $(this).css({color:'#59B'}); var url = "http://www.ratemysong.net/boxes/voted.php?note="; url = url + $(this).attr('id'); $.get(url, function(data){ $('#basic-modal-content').html(data); $("#basic-modal-content").modal(); }); rating[song_num] = $(this).attr('id'); } else { $("#already_voted").modal(); } break; }); } else { $('#rating ul li a').each(function() { $(this).removeAttr('href'); $(this).css("color","#000"); var id_value = $(this).attr("id"); $(this).css("color","#FFF"); if(id_value == data) { $(this).css("color","#59B"); } }); } }); }

  • Maven webapp with Eclipse and WTP plugin deploy files in stranges ways in Tomcat

    - by hokkos
    Hi, I use Eclipse J2EE 3.5 with Maven and tomcat. To deploy my maven webapp with WTP I added a Dynamic Web Module facet and changed the "org.eclipse.wst.common.component" file of the project because the webapp is not in a WebContent directory, here is the content of the file: <?xml version="1.0" encoding="UTF-8"?> <project-modules id="moduleCoreId" project-version="1.5.0"> <wb-module deploy-name="tkey-ca-web"> <wb-resource deploy-path="/" source-path="/src/main/webapp"/> <wb-resource deploy-path="/WEB-INF/classes" source-path="/src/main/java"/> <wb-resource deploy-path="/WEB-INF/classes" source-path="/src/main/resources"/> <property name="context-root" value="toto"/> <property name="java-output-path" value="/toto/target/classes"/> </wb-module> </project-modules> But it never deploy the content correctly, in "workspace.metadata.plugins\org.eclipse.wst.server.core\tmp1\wtpwebapps\toto\" the directory structure is correct with WEB-INF and META-INF but empty, the jsp, html, css files are in "workspace.metadata.plugins\org.eclipse.wst.server.core\tmp1\wtpwebapps\toto\WEB-INF\classes\" with another WEB-INF and META-INF structure but with the files. I don't understand this at all, thanks.

  • How to get cursor to follow text when reading a web page?

    - by Jack BeNimble
    I know this isn't strictly program related, but I think I've seen this answer on SO before and lost track of it. The specific question has to do with reading an electronic document. I find it helpful to move the cursor across the words as I'm reading them. This works great with Word documents, but I'm unable to do it with web pages. Is there a way to make a web page see and respond to cursor movement?

  • How to insert JSP functionality in Servlets?

    How can I use Servlets to access the HTML uses of having JSP without having to have all my client-facing pages called *.jsp? I would rather do this than using all the response.write() stuff because I think it is easier to read and maintain when it is all clean "HTML". Is this is fair assesment?

    - by Mariana Hernandez
    I have a modal where i insert some data, but when i open the modal, close it, and the click the modal show button again, it doesnt submit of course because the validate is "acting" in the modal, but i closed it so its not showing... how can i prevent this? thanks it is similar to this jquery functions within modal only work on first open, after close and re-open they stop working but my functions are <script> $(document).ready(function() { $("#myModal").modal('show'); }); </script> and the validation one <script> $(document).ready(function(){ $('#form1').validate( { ignore: "", rules: { usu_login: { required: true }, usu_password: { required: true }, usu_email: { required: true }, usu_nombre1: { required: true }, usu_apellido1: { required: true }, usu_fecha_nac: { required: true }, usu_cedula: { required: true }, usu_telefono1: { required: true }, rol_id: { required: true }, dependencia_id: { required: true }, }, highlight: function(element) { $(element).closest('.grupo').addClass('has-error'); if($(".tab-content").find("div.tab-pane.active:has(div.has-error)").length == 0) { $(".tab-content").find("div.tab-pane:hidden:has(div.has-error)").each(function(index, tab) { var id = $(tab).attr("id"); $('a[href="#' + id + '"]').tab('show'); }); } }, unhighlight: function(element) { $(element).closest('.grupo').removeClass('has-error'); } }); }); </script> So i dont know how to apply the answer of the above =(

  • problems with build params for accepts_nested_attributes_for

    - by holden
    I'm trying to add the user_id to a nested attribute that gets built by a parent controller but it doesn't seem to have the desired effect? Ie. I have a model called Place.rb which accepts_nested_attributes_for :reviews The nested attribute works fine and I build it inside the Places controller like so... @review = @place.reviews.build(:user_id => current_user.id) I was previously adding the user thru the form, but would like to do it thru the controller so that it only adds the user_id on creation, as it might get updated by someone else and i don't want the update changing the user_id... old way which works: <%= e.label :content, "Review" %><br /> <%= e.text_area :content, :rows => 20, :class => 'jquery_ckeditor' %><br /> <%= e.hidden_field :user_id, :value => current_user.id %> but thru the controller the build method with options has no effect? Any ideas? Can I not do this thru the build?
