• Good object/DB set-up for CMS-esque app for managing content and user permissions?

  - by sah302

  Hi all, so I am writing a big CMS-esque app to allow users to manage web content through web applications, I've got a pretty good db-driven user permission system going, but am having trouble coming up with a good way to handle content groups and pages, I've got a couple options and not sure which one to take. Furthermore, I am not sure how to handle static page updates that have no 'widgets' in them. My current set-up for permissions is this: Objects: User, UserGroup, UserUserGroup, UserGroupType Standard many to many relationship User -> UserUserGroup <- UserGroup each Usergroup has a UserGroupType, which could be anything from Title, Department, to PermissionGroup. PermissionGroup manages the permissions. Right now on a per page basis I check permissions based on their PermissionsGroups. So for a page which has CMS features for a news widget, I check for permission groups of "Site Admin" and "News Admin". Now the issue I am coming to is, the site has many different departments involved. No problem I think, I can just have a EntityContentGroup so any widget app can be used for any departments. So my HR department, each of their news items would be in the EntityContentGroup with the news item ID, and content group of "HR" or "HR News". But maybe this isn't the most efficient way to go about it? I don't want to put the content group simply as a NewsItemType because some news items could apply to multiple areas, so I want to be able to assign them to as many areas as I want. Likewise, all of my widget apps have this, so that's why I decided to choose EntityContentGroup and not just NewsItemContentGroup. I was also thinking well instead of doing a contentGroup do a Page object that says which page some entity should be on. It seems almost like the same thing, but would I want to use Page for something else? I was thinking Page would be used for static pages with no widgets, a simple Rich Text Editor can edit the content of that page and I save that item to a page?? And then instead of doing a page level check for UserGroup permissions, would it be better to associate a usergroup to a contentgroup, and then just depending on what contentGroup content on the page is displayed, determine the permissions through that relationship? Is that better? I am not sure at this point. I guess I am just getting a tad overwhelmed at this is the largest app in scope and size that I have ever written. What is the best approach for this based on my current user permission set-up?

• Javascript Rich Display Component/Methodology

  - by Laramie

  quick back story-- I am working on ASP.Net based template editor that lets authors create text templates using Javascript inserted placeholder tags that will be filled in with dynamic text when the templates are used to display the final results. For example the author might create a template like The word [%12#add] was generated dynamically. The application would eventually replace the tag with a dynamic word down the road (though it's not specifically relevant to this post) The word foo was generated dynmamically. Depending on the circumstances, the template may be created in a text input, textarea or a modified version of the Ajax Control Toolkit HTML Editor. There might be 40 or more of these editable elements on the page, so using lots of stripped down or modified HTML editors would probably bog the page down too much. The problem is that the tags such as [%12#add] are displayed inline with the user text and the result is confusing and aesthetically gross. The goal is parse the contens of the source element and when a tags such as [%12#add] are encountered, display something prettier and less cryptic to the user such as a stylable element or image wherever tags such as [%12#add] occur. The application still needs the template text with the tags on postback. So the user might see The word tag placeholder was generated dynamically. but the original template would still be the value of the text input box The word [%12#add] was generated dynamically. It seems HTML editors like the ACT version and FckEditor accomplish this by rendering their output in an IFrame, but rather than kill myself trying to roll a lighter specialized version myself, I thought I'd ask if anyone knows of an existing free component or approach that has already tackled this. With good reason, I don't think S.O. allows HTML formatting, but the bold "tag placeholder" above would ideally be something like tag placeholder.

• Switching from form_for to remote_form_for problems with submit changes in Rails

  - by Matthias Günther

  Hi there, another day with Rails and today I want to use Ajax. linkt_remote_link for changing a text was pretty easy so I thought it would also be easy to switch my form_for loop just to an ajax request form with remote_form_for, but the problem with the remote_form_for is that it doesn't save my changes? Here the code that worked: <% form_for bill, :url => {:action => 'update', :id => bill.id} do |f| %> # make the processing e.g. displaying texfields and so on <%= submit_tag 'speichern'%> It produces the following html code: <form action="/adminbill/update/58" class="edit_bill" id="edit_bill_58" method="post"><div style="margin:0;padding:0;display:inline"><input name="_method" type="hidden" value="put" /></div> <!-- here the html things for the forms --> <input class="button" name="commit" type="submit" value="speichern" /> Here the code which don't save me the changes and submit them: <% remote_form_for bill, :url => {:action => 'update', :id => bill.id} do |f| %> # make the processing e.g. displaying texfields and so on <%= submit_tag 'speichern'%> It produces the following html code: <form action="/adminbill/update/58" class="edit_bill" id="edit_bill_58" method="post" onsubmit="$.ajax({data:$.param($(this).serializeArray()), dataType:'script', type:'post', url:'/adminbill/update/58'}); return false;"><div style="margin:0;padding:0;display:inline"><input name="_method" type="hidden" value="put" /></div> <!-- here the html things for the forms --> <input class="button" name="commit" type="submit" value="speichern" /> I don't know if I have to consider something special when using remote_form_for (see remote_form_for)

• backbone.js removing template from DOM upon success

  - by timpone

  I'm writing a simple message board app to learn backbone. It's going ok (a lot of the use of this isn't making sense) but am a little stuck in terms of how I would remove a form / html from the dom. I have included most of the code but you can see about 4 lines up from the bottom, the part that isn't working. How would I remove this from the DOM? thx in advance var MbForm=Backbone.View.extend({ events: { 'click button.add-new-post': 'savePost' }, el: $('#detail'), template:_.template($('#post-add-edit-tmpl').html()), render: function(){ var compiled_template = this.template(); this.$el.html(compiled_template); return this; }, savePost: function(e){ //var self=this; //console.log("I want you to say Hello!"); data={ header: $('#post_header').val(), detail: $('#post_detail').val(), forum_id: $('#forum_id').val(), post_id: $('#post_id').val(), parent_id: $('#parent_id').val() }; this.model.save(data, { success: function(){ alert('this saved'); //$(this.el).html('this is what i want'); this.$el.remove();// <- this is the part that isn't working /* none of these worked - error Uncaught TypeError: Cannot call method 'unbind' of undefined this.$el.unbind(); this.$el.empty(); this.el.unbind(); this.el.empty(); */ //this.unbind(); //self.append('this is appended'); } });

• prevent javascript in the WMD editor's preview box

  - by Justin Grant

  There are many SO questions (e.g. here and here) about how to do server-side scrubbing of Markdown produced by the WMD editor to ensure the HTML generated doesn't contain malicious script, like this: <img onload="alert('haha');" src="http://www.google.com/intl/en_ALL/images/srpr/logo1w.png" /> Unfortunately, this still allows script to show up in the WMD client's preview box. I doubt this is a big deal since if you're scrubbing the HTML on the server, an attacker can't save the bad HTML so no one else will be able to see it later and have their cookies stolen or sessions hijacked by the bad script. But it's still kinda odd to allow an attacker to run any script in the context of your site, and it's probably a bad idea to allow the client preview window to allow different HTML than your server will allow. StackOverflow has clearly plugged this hole. How did they do it? [NOTE: I already figured this out but it required some tricky javascript debugging, so I'm answering my own question here to help others who may want to do ths same thing]

• WYSIWYG in Doxygen

  - by Adam Shiemke

  I'm working on a fairly large project written in C. The idea was to build a library of modular blocks that can be reused across several platforms. Each module is assocaited with a word document in .docx format (huge pain to diff-merge). In these docs, an interface section is specified, listing datatypes and publicly accessable functions. These were often inconsistant with the actual implementation in code, and wading through all this documentation was a pain. I've been working to switch to doxygen to simplify document managemnet. I haven't found a good way to embed the previously written documentation into the doxygen output. I've copy-pasted them into sections and used modules to group the sources together, but the document sections look ugly in the comments (the output is pretty) and since doxygen takes a while to parse through our code (about 30 mins), validating formatting is a pain. Is there some way to WYSIWIG large blocks of documentation into doxygen? I feel this would improve the number of people documenting their code, and the quality of that documentation. I considered linking to html, but that splits out the documentation. I also considered putting them inline in html, but this also seems like a pain and would mean everyone needs a WYSIWIG HTML edditor (or some html skillz). Any ideas on how to make things easier and prettier? Thanks loads.

• $.ajax not loading data data everytime from server

  - by Ted

  I have written a simple jQuery.ajax function which loads a user control from the server on click of a button. The first time I click the button, it goes to the server and gets me the user control. But each subsequent click of the same button does not goes to the server to fetch me the user control. Since my user control fetches data from db, I need to reload the user control everytime i hit the button. But if anyhow I get my user control to unload from the page, and re-click the button, it goes to the server and fetches me the user control. Here's the code: $("#btnLoad").click(function() { if ($(this).attr("value") == "Load Control") { $.ajax({ url: "AJAXHandler.ashx", data: { "lt": "loadcontrol" }, dataType: "html", success: function(data) { content.html(data); } }); $(this).attr("value", "Unload Control"); } else { $.ajax({ url: "AJAXHandler.ashx", data: { "lt": "unloadcontrol" }, dataType: "html", success: function(data) { content.html(data); } }); $(this).attr("value", "Load Control"); } }); Please let me know if there is any other way I can get my user control loaded from server everytime I click the button.

• What is the "Dispatcher" design pattern?

  - by Ben Farmer

  What is the "dispatcher" pattern and how would I implement it in code? I have a property bag of generic objects and would like to have the retrieval delegated to a generic method. Currently, I have properties looking for a specific key in the bag. For example: private Dictionary<String, Object> Foo { get; set; } private const String WidgetKey = "WIDGETKEY"; public Widget? WidgetItem { get { return Foo.ContainsKey(WidgetKey) ? Foo[WidgetKey] as Widget: null; } set { if (Foo.ContainsKey(WidgetKey)) Foo[WidgetKey] = value; else Foo.Add(WidgetKey, value); } } It was suggested that this could be more generic with the "dispatcher" pattern, but I've been unable to find a good description or example. I'm looking for a more generic way to handle the property bag store/retrieve.

• How can I get jQuery to perform a synchronous, rather than asynchronous, AJAX request?

  - by Artem Tikhomirov

  Hello. I have a javascript widget witch provides standard extension points. One of them is the beforecreate function. It should return false to prevent an item from being created. I've added an AJAX call into this function using jQuery: beforecreate: function(node,targetNode,type,to) { jQuery.get('http://example.com/catalog/create/' + targetNode.id + '?name=' + encode(to.inp[0].value), function(result) { if(result.isOk == false) alert(result.message); }); } But I want to prevent my widget from creating the item, so I should return false in the mother-function, not in the callback. Is there any way to perform a synchronized AJAX request using jQuery or any other API? Thanks.

  I am having a problem with my struts application it is a class enrollment app and when the user clicks on a "show enrolled courses" button it is supposed to show the courses they are enrolled in but it shows nothing at the moment.

• PHP & cUrl - POST problems in while loop.

  - by Max Hoff

  I have a while loop, with cUrl inside. (I can't use curl_multi for various reasons.) The problem is that cUrl seems to save the data it POSTS after each loop traversal. For instance, if parameter X is One the first loop through, and if it's Two the second loop through, cUrl posts: "One,Two". It should just POST "Two".(This is despite closing and unsetting the curl handle.) Here's a simplified version of the code (with unecessary info stripped out): while(true){ // code to form the $url. this code is local to the loop. so the variables should be "erased" and made new for each loop through. $ch = curl_init(); $userAgent = 'Googlebot/2.1 (http://www.googlebot.com/bot.html)'; curl_setopt($ch,CURLOPT_USERAGENT, $userAgent); curl_setopt($ch,CURLOPT_URL,$url); curl_setopt($ch,CURLOPT_POST,count($fields)); curl_setopt($ch,CURLOPT_POSTFIELDS,$fields_string); curl_setopt($ch, CURLOPT_FAILONERROR, true); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); curl_setopt($ch, CURLOPT_AUTOREFERER, true); curl_setopt($ch, CURLOPT_RETURNTRANSFER,true); curl_setopt($ch, CURLOPT_TIMEOUT, 10); $html = curl_exec($ch); curl_close($ch); unset($ch); $dom = new DOMDocument(); @$dom->loadHTML($html); $xpath = new DOMXPath($dom); $resultTable = $xpath->evaluate("/html/body//table"); // $resultTable is 20 the first time through the loop, and 0 everytime thereafter becauset he POSTing doesn't work right with the "saved" parameters. What am I doing wrong here?

• Strange javascript decoding behavior in IE

  - by Yoni

  I run the following html snippet in IE8 and IE7 with non-English characters (we tried both Hebrew and Chinese), and the second link never works properly. The displayed text in the alert box is mangled. This occurs in IE8 and IE7, but not in firefox. It is not dependent on Windows's regional settings. Here is the html snippet (html header and footer omitted for brevity, the content-type is "text/html; charset=utf-8", and so is the response header): <p> <a href="javascript:alert('ab????ab')">link with English and Hebrew text</a> <a href="javascript:alert('ab%D7%A9%D7%9C%D7%95%D7%9Dab')">same text, url encoded</a> </p> Here is the alert box that pops up when clicking the second link: I know that the string for "????" is encoded as 8 bytes in utf-8, thus there are 8 %NN items, and there are also 8 weird characters in the alert box. The problem is, how can I make IE recognize that this is utf-8 encoding text, like firefox does?

• Chrome is leaking memory, when jQuery is used on events?

  - by user269386

  Hi, I'm experiencing an increase of memory usage, when I use the jQuery-eventhandling in Chrome. I've tested it with IE and FF as well, but there I couldn't see a suspicious rise of memory-usage, compared to Chrome. I'm using Chrome version 4.0.223.16 (unfortunately I'm forced to use this version, here) Simple example here. Just scroll with the mousewheel in the red box and open the Chrome-taskmanager and you will see an increase of memory which won't be released anymore: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <script type="text/javascript" src="js/libs/jquery-1.4.2.min.js"></script> <script type="text/javascript"> jQuery(function () { jQuery("#div1").bind("mousewheel", function (event) { event.preventDefault(); }); }); </script> </head> <body> <div id="div1" style="width: 100px; height: 100px; background-color: red;"></div> </body> </html> Does anyone have experienced the same problem (or is it maybe solvend with a different version of chrome)? And does anyone have a fix for it? thanks

• jquery touch punch - draggable on ipad

  - by dshuta

  i am starting to work with the jquery touch punch extensions in order to allow draggability on ipad, but i am getting tripped up right away. probably something terribly dumb on my part. the draggable example from the developer works fine on my ipad: http://furf.com/exp/touch-punch/draggable.html but not for me: http://danshuta.com/touchpunch/ this works fine in my desktop browser, but on the ipad it just focuses on the block and scrolls the entire page as i drag, as if it were just an image or other normal embedded object. as this is what happens normally with jquery/ui on ipad, this makes me think it is not loading or otherwise ignoring the "punch" code from my site (though if i host the jquery files on my site via the same path, those load and function fine in desktop browser). here's the entire code, very basic: <!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8" /> <title>Touchpunchtest</title> <script src="http://code.jquery.com/jquery.min.js"></script> <script src="http://code.jquery.com/ui/1.8.17/jquery-ui.min.js"></script> <script src="js/jquery.ui.touch-punch.js"></script> </head> <body> <div id="draggybox" onclick="void(0)" style="width: 150px; height: 150px; background: green;"></div> <script>$('#draggybox').draggable();</script> </body> </html> what am i missing?!

• Play youtube video in full screen ?

  - by Madhup

  Hi all, First of all sorry, If somebody finds this question is repeated (haven't found any by myself). I am developing for an iPad application and trying to play youtube videos using this code: NSString *embedHTML = @"\ <html><head>\ <style type=\"text/css\">\ body {\ background-color: transparent;\ color: white;\ }\ </style>\ </head><body style=\"margin:0\">\ <embed id=\"yt\" src=\"%@\" type=\"application/x-shockwave-flash\" \ width=\"%0.0f\" height=\"%0.0f\"></embed>\ </body></html>"; NSString *html = [NSString stringWithFormat:embedHTML, youTubeUrl, 142.0, 129.5]; [wbView loadHTMLString:html baseURL:nil]; The code works fine when used in an iphone application (i.e. you touch on the webview and it starts playing the youtube video in fullscreen.) But when used in the iPad, on clicking the web view it starts playing the video in the web view itself and shows options to go to full screen, while I want to start the playback in the full screen from the beginning, like it does in the iPhone. Anybody having some ideas or people who have done it before please help. Thanks, Madhup

• ASP .NET confusion - server controls

  - by Brandi

  I have read through the information in this question: http://stackoverflow.com/questions/22084/asp-net-aspxxx-controls-versus-standard-html but am still rather confused. The situation was I was asked to do a web project where I made a wizard. When I was done with the project everyone asked why I had used an <asp:Wizard...>. I thought this was what was being asked for, but apparently not, so after this I was led to believe that server controls were just prototyping tools. However, the next project I did my DB queries through C# code-behind and loaded the results via html. I was then asked why I had not used a gridview and a dataset. Does anyone have a list of pros and cons why they would choose to use specific html controls over specific server controls and why? I guess I'm looking for a list... what server controls are okay to use and why? EDIT: I guess this question is open ended, so I'll clarify a few more specific questions... Is it okay to use very simple controls such as asp:Label or do these just end up wasting space? It seems like it would be difficult to access html in the code behind otherwise. Are there a few controls that should just never be used? Does anyone have a good resource that will show me pros and cons of each control?

QPen(Qt::green) : QPen(Qt::yellow); i++; update(boxRect); } This code does not working properly. What is wrong?
