  • Facebook like button issue.

    - by Ross Hale
    Hello community, We're having some trouble getting our like button to work. It seemed to work last week but suddenly it's stopped working. Basically when clicking "Like", we get an error saying: You failed to provide a valid list of administators. You need to supply the administors using either a "fb:app_id" meta tag, or using a "fb:admins" meta tag to specify a comma-delimited list of Facebook users. Our section looks like this: <html xmlns="http://www.w3.org/1999/xhtml" xmlns:og="http://opengraphprotocol.org/schema/" xmlns:fb="http://www.facebook.com/2008/fbml" xml:lang="en" lang="en"> <head> <meta property="fb:app_id" content="number"/> <meta property="fb:admins" content="number"/> <meta property="og:title" content="title"/> <meta property="og:type" content="website"/> <meta property="og:url" content="url with trailing slash"/> <meta property="og:image" content="url to image"/> <meta property="og:site_name" content="Site Name"/> </head> Help?

  • How to format the Facebook news feed description of grouped app posts?

    - by JcFx
    I have an app which posts a message like this to a user's Facebook timeline: This is working fine, but if I post a few times, my posts get grouped on my news feed, and I get this: What settings should I use to control the way this news report appears? Instead of 'All about periods' and the page link in the box at the top, I'd like 'Body iQ Quiz' and the app description. Where would I set these values? And is it possible to make the grouped report say 'Jay cee Effex shared a link via Body iQ Quiz', the way the original post does? I'm posting from the Facebook AS3 API, and my post code looks like this: var auth:FacebookAuthResponse = Facebook.getAuthResponse(); var token:String = auth.accessToken; var user:String = auth.uid; var values:Object = { access_token: token, name: "Body iQ Quiz", picture: "http://a7.sphotos.ak.fbcdn.net/hphotos-ak-snc6/282950_427728213914009_630526316_n.jpg", link:"http://www.lil-lets.co.uk/en-GB/Wellbeing", description: "Women, how well do we know our bodies? Click here to find out what your Body iQ is.", message: result.FacebookBody + " " + result.FacebookTitle }; Facebook.api("/" + user + "/feed", handleSubmitFeed, values, URLRequestMethod.POST); ... but I'm not sure if this is something I can fix in code, or if the app configuration needs tweaking? NOTE: Some users report getting the latter format in their news feed even with a single post (I can't reproduce this), so perhaps grouping is a red herring, and the real question is how to format the news feed report of a timeline post?

  • Efficient representation of Hierarchies in Hibernate.

    - by Alison G
    I'm having some trouble representing an object hierarchy in Hibernate. I've searched around, and haven't managed to find any examples doing this or similar - you have my apologies if this is a common question. I have two types which I'd like to persist using Hibernate: Groups and Items. * Groups are identified uniquely by a combination of their name and their parent. * The groups are arranged in a number of trees, such that every Group has zero or one parent Group. * Each Item can be a member of zero or more Groups. Ideally, I'd like a bi-directional relationship allowing me to get: * all Groups that an Item is a member of * all Items that are a member of a particular Group or its descendants. I also need to be able to traverse the Group tree from the top in order to display it on the UI. The basic object structure would ideally look like this: class Group { ... /** @return all items in this group and its descendants */ Set<Item> getAllItems() { ... } /** @return all direct children of this group */ Set<Group> getChildren() { ... } ... } class Item { ... /** @return all groups that this Item is a direct member of */ Set<Group> getGroups() { ... } ... } Originally, I had just made a simple bi-directional many-to-many relationship between Items and Groups, such that fetching all items in a group hierarchy required recursion down the tree, and fetching groups for an Item was a simple getter, i.e.: class Group { ... private Set<Item> items; private Set<Group> children; ... /** @return all items in this group and its descendants */ Set<Item> getAllItems() { Set<Item> allItems = new HashSet<Item>(); allItems.addAll(this.items); for(Group child : this.getChildren()) { allItems.addAll(child.getAllItems()); } return allItems; } /** @return all direct children of this group */ Set<Group> getChildren() { return this.children; } ... } class Item { ... private Set<Group> groups; /** @return all groups that this Item is a direct member of */ Set<Group> getGroups() { return this.groups; } ... } However, this resulted in multiple database requests to fetch the Items in a Group with many descendants, or for retrieving the entire Group tree to display in the UI. This seems very inefficient, especially with deeper, larger group trees. Is there a better or standard way of representing this relationship in Hibernate? Am I doing anything obviously wrong or stupid? My only other thought so far was this: Replace the group's id, parent and name fields with a unique "path" String which specifies the whole ancestry of a group, e.g.: /rootGroup /rootGroup/aChild /rootGroup/aChild/aGrandChild The join table between Groups and Items would then contain group_path and item_id. This immediately solves the two issues I was suffering previously: 1. The entire group hierarchy can be fetched from the database in a single query and reconstructed in-memory. 2. To retrieve all Items in a group or its descendants, we can select from group_item where group_path='N' or group_path like 'N/%' However, this seems to defeat the point of using Hibernate. All thoughts welcome!

  • Financial Charts / Graphs in Ruby or Python

    - by Eric the Red
    What are my best options for creating a financial open-high-low-close (OHLC) chart in a high level language like Ruby or Python? While there seem to be a lot of options for graphing, I haven't seen any gems or eggs with this kind of chart. http://en.wikipedia.org/wiki/Open-high-low-close_chart (but I don't need the moving average or Bollinger bands) JFreeChart can do this in Java, but I'd like to make my codebase as small and simple as possible. Thanks!

  • Did anyone have this issue with a simple Facebook app or know how to solve it?

    - by Jian Lin
    I have a really simple few lines of Facebook app, using the new Facebook API: <pre> <?php require 'facebook.php'; // Create our Application instance. $facebook = new Facebook(array( 'appId' => '117676584930569', 'secret' => '**********', // hidden here on the post... 'cookie' => true, )); var_dump($facebook); ?> but it is giving me the following output: http://apps.facebook.com/woolaladev/i2.php would give out object(Facebook)#1 (6) { ["appId:protected"]=> string(15) "117676584930569" ["apiSecret:protected"]=> string(32) "**********" <--- just hidden on this post ["session:protected"]=> NULL ["sessionLoaded:protected"]=> bool(false) ["cookieSupport:protected"]=> bool(true) ["baseDomain:protected"]=> string(0) "" } Session is NULL for some reason, but I am logged in and can access my home and profile and run other apps on Facebook (to see that I am logged on). I am following the sample on: http://github.com/facebook/php-sdk/blob/master/examples/example.php http://github.com/facebook/php-sdk/blob/master/src/facebook.php (download using raw URL: wget http://github.com/facebook/php-sdk/raw/master/src/facebook.php ) Trying on both hosting companies at dreamhost.com and netfirms.com, and the results are the same.

  • Is there a way to efficiently update one value in dojo chart2d?

    - by Nick Orlowski
    I am looking for a way to update one and only one value in a dojox chart2d. There is a way to update an entire series, which involves mychart.updateSeries("myseriesname",array_of_data) mychart.render() but This is too slow for my application. What I want to do is be able to drag the mouse over a vertical bar chart and have the values change as I am doing it. Only one or two values will need to change, so there is no need to reload all of the plots, just the two or three values that are changing. Is there a method that will quickly update only one or two values without lag? Thanks, Nick O I may just end up writing my own css version :S

  • How to do binding programmically?

    - by user175908
    Hello, Could anyone identify the problem in this code? (I'm kinda newbie in WPF bindings.) This code executes after chart is loaded when I click a button: I get this error: Update: I dont get that error anymore. Thanks to Tomas. Now no error occur but chart looks completely blank (no columns) Update: Code now looks like this: // create a very simple DataSet var dataSet = new DataSet("MyDataSet"); var table = dataSet.Tables.Add("MyTable"); table.Columns.Add("Name"); table.Columns.Add("Price"); table.Rows.Add("Brick", 1.5d); table.Rows.Add("Soap", 4.99d); table.Rows.Add("Comic Book", 0.99d); // chart series var series = new ColumnSeries() { IndependentValueBinding = new Binding("[Name]"), // How to deal with DependentValueBinding = new Binding("[Price]"), // these two? ItemsSource = dataSet.Tables[0].DefaultView // or maybe I do mistake here? }; // ---------- set additional binding as adviced ------------------ series.SetBinding(ColumnSeries.ItemsSourceProperty, new Binding()); // chart stuff MyChart.Series.Add(series); MyChart.Title = "Names 'n Prices"; // some code to remove legend var style = new Style(typeof(Control)); style.Setters.Add(new Setter(LegendItem.TemplateProperty, null)); MyChart.LegendStyle = style; XAML: <Window x:Class="BindingzTest.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="606" Width="988" xmlns:charting="clr-namespace:System.Windows.Controls.DataVisualization.Charting;assembly=System.Windows.Controls.DataVisualization.Toolkit"> <Grid Name="LayoutRoot"> <charting:Chart Name="MyChart" Margin="0,0,573,0" Height="289" VerticalAlignment="Top" /> <Button Content="Button" Height="23" HorizontalAlignment="Left" Margin="272,361,0,0" Name="button1" VerticalAlignment="Top" Width="75" Click="chart1_Loaded" /> </Grid> Thanks for help in advance once more.

  • How to get Facebook Login Button To Display "Logout"

    - by Will Merydith
    I apologize ahead of time if this is clearly documented somewhere on the FB developer site - but I can't find it (so please link me if appropriate). I've implemented the FB login button on a website using GAE + Python. Here is the HTML: <fb:login-button></fb:login-button> <div id="fb-root"></div> <script src="http://connect.facebook.net/en_US/all.js"></script> <script> FB.init({appId: 'ad16a806fc10bef5d30881322e73be68', status: true, cookie: true, xfbml: true}); FB.Event.subscribe('auth.sessionChange', function(response) { if (response.session) { // A user has logged in, and a new cookie has been saved } else { // The user has logged out, and the cookie has been cleared } }); </script> Currently the behavior is - if I click on the "login" button, I am asked to allow the application access to FB. Which I then choose, "OK". But then the login button is still showing "login" and not "logout". How do I implement that? On the server or client side?

  • Facebook redirect after login not working when url is dynamic

    - by dythffvrb
    This is my code: $loginUrl = $facebook->getLoginUrl(array( 'scope' => 'publish_actions', 'redirect_uri' => 'http://mysite.com/', )); It works but if I remove redirect_uri it doesn't work anymore. $loginUrl = $facebook->getLoginUrl(array( 'scope' => 'publish_actions' )); According to Facebook domcumentation redirect_uri is optional. https://developers.facebook.com/docs/reference/php/facebook-getLoginUrl/ Im trying to redirect the users to the same url they were on before logging in. Update: This problem occurs when the url is mysite.com/post23 but when url is mysite.com/staticpage or mysite.com there are no problems Any workarounds? EDIT: It looks like a bug, it doesn't work with certain url in the same site I wil try and report it to Facebook.

  • Why can't I access the facebook friends list after reopening a session in ios

    - by user1532390
    I am upgrading to the facebook 3.0 sdk for ios. Things went well, until I tried to open an existing session after relaunching the application. I am trying to access the list of friends for the facebook user. if ([[FBSession activeSession] isOpen]) { [request startWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) { //do something here }]; }else{ [[self session] openWithCompletionHandler:^(FBSession *session, FBSessionState status, NSError *error) { if ([self isValid]) { [request startWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) { //log this error we always get NSLog(@"%@",error); //do something else }]; } }]; } However I get this error: Error Domain=com.facebook.sdk Code=5 "The operation couldn’t be completed. (com.facebook.sdk error 5.)" UserInfo=0x1d92ff40 {com.facebook.sdk:ParsedJSONResponseKey={ body = { error = { code = 2500; message = "An active access token must be used to query information about the current user."; type = OAuthException; }; }; code = 400; }, com.facebook.sdk:HTTPStatusCode=400} I've found that if I use the FBSession reauthorize method it allows me to complete the request without error, but it also means I must show UI or switch apps every time we relaunch the application which is unacceptable. Any suggestions on what I should be doing differently?

  • What is the best data structure and algorithm for comparing a list of strings?

    - by Chiraag E Sehar
    I want to find the longest possible sequence of words that match the following rules: Each word can be used at most once All words are Strings Two strings sa and sb can be concatenated if the LAST two characters of sa matches the first two characters of sb. In the case of concatenation, it is performed by overlapping those characters. For example: sa = "torino" sb = "novara" sa concat sb = "torinovara" For example, I have the following input file, "input.txt": novara torino vercelli ravenna napoli liverno messania noviligure roma And, the output of the above file according to the above rules should be: torino novara ravenna napoli livorno noviligure since the longest possible concatenation is: torinovaravennapolivornovilligure Can anyone please help me out with this? What would be the best data structure for this?

  • Permanent access token to an app that posts to a fan page - error code:1

    I'm following the steps very well described here http://stackoverflow.com/a/18399927/2510225 , but, from my server, I receive the following error: {"error":{"message":"The access token does not belong to application APP-ID","type":"OAuthException","code":1}} I can't figure what I'm doing wrong. Anyone knows if the process to get a permanent access token has changed, or is having the same issue? The access token I'm using in the request is the user access token, which I think is correct.

  • How someone using my Facebook website app can post to their pages timeline

    - by user1334414
    I have a website where businesses create content through a PHP backend system. Each time they create a new piece of content, I want it to publish to their Facebook pages timeline (not the users timeline). I have created the authenticate code: <div id="fb-root"></div> <script> window.fbAsyncInit = function() { FB.init({ appId : 'XXXXXXXXXX', status : true, cookie : true, xfbml : true, oauth : true, }); }; (function(d){ var js, id = 'facebook-jssdk'; if (d.getElementById(id)) {return;} js = d.createElement('script'); js.id = id; js.async = true; js.src = "//connect.facebook.net/en_US/all.js"; d.getElementsByTagName('head')[0].appendChild(js); }(document)); </script> <div class="fb-login-button" scope="manage_pages"> Login with Facebook </div> With manage_pages as a scope. I need to know how they can select which page they want the post to go to (if they have more than 1 page), and also how to automatically post to that pages wall when they submit the content (which is done via a PHP form). Thanks

  • Height of a binary tree

    - by Programmer
    Consider the following code: public int heightOfBinaryTree(Node node) { if (node == null) { return 0; } else { return 1 + Math.max(heightOfBinaryTree(node.left), heightOfBinaryTree(node.right)); } } I want to know the logical reasoning behind this code. How did people come up with it? Does some have an inductive proof? Moreover, I thought of just doing a BFS with the root of the binary tree as the argument to get the height of the binary tree. Is the previous approach better than mine?Why?

  • Are mathamatical Algorithms protected by copyright

    - by analogy
    I wish to implement an algorithm which i read in a journal paper in my software (commercial). I want to know if this is allowed or not. The algorithm in question is described in http://arxiv.org/abs/0709.2938 It is a very simple algorithm and a number of implementations exist in python (http://igraph.sourceforge.net/) and java. One of them is in gpl another which i got from a different researcher and had no license attached. There are significant differences in two implementations, e.g. second one uses threads and multiple cores. It is possible to rewrite/ (not translate) the algorithm. So can I use it in my software or on a server for commercial purpose. Thanks

  • Facebook iOS SDK Share Dialog - Sharing on a Friend's Wall

    - by JPK
    Is it possible to use the Facebook iOS SDK Share Dialog to share on a Friend's Wall? I know that it is possible to do this using the Feed Dialog, but that provides the user with a less than optimal experience, and seems to be discouraged by Facebook. It would be fantastic if we could configure the Share Dialog to share with one particular friend. Additionally, is there a way to share with a friend privately (such that it would be sent to Messages)? I have researched pretty extensively and it seems like there is not a way to do either of these things using the iOS SDK - I would just like to confirm that I am not missing something.
