  • POST from edit/create partial views loaded into Twitter Bootstrap modal

    - by mare
    I'm struggling with AJAX POST from the form that was loaded into Twitter Bootstrap modal dialog. Partial view form goes like this: @using (Html.BeginForm()) { // fields // ... // submit <input type="submit" value="@ButtonsRes.button_save" /> } Now this is being used in non AJAX editing with classic postbacks. Is it possible to use the same partial for AJAX functionality? Or should I abstract away the inputs into it's own partial view? Like this: @using (Ajax.BeginForm()) { @Html.Partial("~/Views/Shared/ImageEditInputs.cshtml") // but what to do with this one then? <input type="submit" value="@ButtonsRes.button_save" /> } I know how to load this into Bootstrap modal but few changes should be done on the fly: the buttons in Bootstrap modal should be placed in a special container (the modal footer), the AJAX POST should be done when clicking Save which would first, validate the form and keep the modal opened if not valid (display the errors of course) second, post and close the modal if everything went fine in the view that opened the modal, display some feedback information at the top that save was succesful. I'm mostly struggling where to put what JS code. So far I have this within the List view, which wires up the modals: $(document).ready(function () { $('.openModalDialog').click(function (event) { event.preventDefault(); var url = $(this).attr('href'); $.get(url, function (data) { $('#modalContent').html(data); $('#modal').modal('show'); }); }); }); The above code, however, doesn't take into the account the special Bootstrap modal content placeholder (header, content, footer). Is it possible to achieve what I want without having multiple partial views with the same inputs but different @using and without having to do hacks with moving the Submit button around?

  • Multiple inputs on a single line with Twitter Bootstrap and Simple Form 2.0

    - by noel_g
    I am using simple_form 2.0 with twitter bootstrap. I am trying to determine what is the proper wrapper format in order to get something like [city] [State] [Zip] I believe my form needs to be <div class="control-group"> <%= f.input :city,:wrapper => :small, :placeholder => "City", :input_html => { :class=>"span2", :maxlength => 10},:label => false %> <%= f.input :region, :wrapper => :small , :placeholder => "Region", :input_html => { :class=>"span1", :maxlength => 5}, :label => false %> <%= f.input :postal_code, :wrapper => :small, :placeholder => "Postal Code",:input_html => { :class=>"span2", :maxlength => 10},:label => false %> </div> I tried this wrapper config.wrappers :small, :tag => 'div', :class => 'controls inline-inputs', :error_class => 'error' do |b| b.use :placeholder b.use :label_input end I believe I would need to define the CSS as well, but before I go down a rabbit hole I thought I would ask if this is built in somewhere.

  • Twitter Bootstrap on page tabs: not hiding tab content

    - by user973424
    I'm trying to get the twitter on page tabbed content to work. I have the tabs working with switching around active class on the tabs. I've included jquery and the bootstrap-tabs.js but the following code can't seem to get the tabbed content to hide / display as they should. Any help on what may be a simple fix would be appreciated. <div class="span8"> <ul class="tabs" data-tabs="tabs"> <li class="active"><a href="#2009">2009</a></li> <li><a href="#2010">2010</a></li> <li><a href="#2011">2011</a></li> </ul> <div class="pill-content"> <div class="active" id="2009"> 2009 copy </div> <div id="2010"> 2010 copy </div> <div id="2011"> 2011 copy </div> </div> <script> $(function () { $('.tabs').tabs() }) </script> </div><!-- end span 8 -->

  • Twitter API similar to Google Alert

    - by Felix Perdana
    I am trying to create a web application which have a similar functionality with Google Alerts. (by similar I mean, the user can provide their email address for the alert to be sent to, daily or hourly) The only limitation is that it only gives alerts to user based on a certain keyword or hashtag. I think that I have found the fundamental API needed for this web application. https://dev.twitter.com/docs/api/1/get/search The problem is I still don't know all the web technologies needed for this application to work properly. For example, Do I have to store all of the searched keywords in database? Do I have to keep pooling ajax request all the time in order to keep my database updated? What if the keyword the user provided is very popular right now that might have thousands of tweets just in an hour (not to mention, there might be several emails that request several trending topics)? By the way, I am trying to build this application using PHP. So please let me know, what kind of techniques I need to learn for such web app (and some references maybe)? Any kind of help will be appreciated. Thanks in advance :) Regards, Felix Perdana

  • twitter bootstrap collapsable nav menu

    - by clifgray
    I am using twitter bootstrap on my web app to do all of the styling and everything is great for the most part. The problem is that my nav bar, once collapsed, will not drop down when I click the dropdown icon. I have listed my HTML but I think the problem is with my javascript seeing as this fiddle with the exact same code: http://jsfiddle.net/YWUmb/30/ works just fine. <div class="navbar navbar-fixed-top"> <div class="navbar-inner"> <div class="container"> <a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse"> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span> </a> <a class="brand" href="/">Exployre</a> <div class="nav-collapse"> <ul class="nav"> <li><a href="/">Home</a></li> <li><a href="/profile">Profile</a></li> <li><a href="/sponsors">Sponsors</a></li> <li><a href="/working">Exployrers</a></li> <li><a href="/about">About</a></li> <li><a href="/share">Share</a></li> <li> {% if user %} User: {{ user }}<br> <a href="{{ logout }}">Logout</a> {% else %} <a href="/login">Signin or Register</a> {% endif %} <li> <a href="/profile"> {% if visits %} {% if visits > 10 %} Prestige: {{ visits }} {% elif visits > 5 %} {% endif %} {% endif %} </a> </li> <li> <form action="/search" class="navbar-search"> <div> <input type="text" placeholder="Search" class="search-query" name="q" size="55"/> </div> </form> <script type="text/javascript" src="http://www.google.com/coop/cse/brand?form=cse-search-box&amp;lang=en"></script> </li> </ul> </div><!--/.nav-collapse --> </div> </div> </div> <script type="text/javascript" src="/static/js/bootstrap.js"></script> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script> Is there anything wrong with my source code links or anything additional that I need to do to make it work?

  • #twitter for Windows Phone 7 protips (#wp7)

    - by Laurent Bugnion
    I started tweeting a list of “protips” (or whatever you want to call that) related to the Twitter for Windows Phone 7 application. Since I worked as integrator on this app, my tasks involved integrating design assets in all screens, and so I had an insider view on all the screens (and that is really a LOT of screens :) Seeing some comments about the app made me understand that most users out there don’t realize how rich the application is, and how many features are available. So without further ado, here we go, a list of Twitter for WP7 protips: (note: I will extend the list if I think of new stuff, and maybe add some screenshots later). Check the dark theme in the application settings! Select a tweet, menu, Translate. Search, Nearby looks for tweets near you Custom searches can be saved. They synch up with web twitter too! Multi language support, independant from OS. supports EN, FR, DE, IT, ES Multiple accounts are supported, simply define them in the Settings Even without a Twitter account, experience is super rich. Trends, Suggested, Nearby, searches etc... Select a tweet, then press Replies To to see the whole conversation Compose, menu, Hashtags. Enter a hashtag and press Add. List is saved for the next time. Select a tweet with location info (like my own). Press the location name to see all Nearby tweets Want to remove location information just for one tweet? Press on the Places button in app bar then Clear Place Settings, General to toggle between Username/Fullname display, Relative/Absolute date/time and more Upload a picture directly from compose screen to TwitPic, yFrog or TweetPhoto (service selection in Settings) Settings, About, Support to see a log of app errors and email it to support (use wisely please) Tap your username to see your profile. Then Menu, Edit Profile to edit your info, including your picture Tap on any user's name to see his profile, tweets, mentions and favorites in a Pivot Happy Tweeting!

  • Integrating Twitter Into An ASP.NET Website Using OAuth

  • Twitter API Voting System

    - by Richard Jones
    So I blatantly got this idea from the MIX 10 event. At MIX they held a rockband talent competition type thing (I’m not quite sure of all the details).    But the interesting part for me is how they collected votes. They used Twitter (what else, when you have a few thousand geeks available to you). The basic idea was that you tweeted your vote with a # tag, i.e #ROCKBANDVOTE vote Richard How cool….    So the question is how do you write something to collate and count all the votes?   Time to press the magic Visual Studio new Project button… Twitter has a really nice API that can be invoked from .NET.   This is the snippet of code that will search for any given phrase i.e #ROCKBANDVOTE   public static XmlDocument GetSearchResults(string searchfor) { return GetSearchResults(searchfor, ""); }   public static XmlDocument GetSearchResults(string searchfor, string sinceid) { XmlDocument retdoc = new XmlDocument();   try { string url = "http://search.twitter.com/search.atom?&q=" + searchfor; if (sinceid.Length > 0) url += "since_id=" + sinceid; HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); request.Method = "POST"; request.ContentType = "application/x-www-form-urlencoded"; WebResponse res = request.GetResponse(); retdoc.Load(res.GetResponseStream()); res.Close();   } catch { } return retdoc; } } I’ve got two overloads, that optionally let you pass in the last ID to look for as well as what you want to search for. Note that Twitter rate limits the amount of requests you can send,  see http://apiwiki.twitter.com/Rate-limiting So realistically I wanted my app to run every hour or so and only pull out results that haven’t been received before (hence the overload to pass in the sinceid parameter). I’ll post the code when finished that parses the returned XML.

  • Silverlight 4 Twitter Client &ndash; Part 7

    - by Max
    Download this article as a PDF Welcome back :) This week we are going to look at something more exciting and a much required feature for any twitter client – auto refresh so as to show new status updates. We are going to achieve this using Silverlight 4 Timers and a bit and refresh our datagrid every 2 minutes to show new updates. We will do this so that we do only minimal request to the twitter api, so that twitter does not block us – there is a limit of 150 request an hour. Let us get started now. Also we will get the profile user id hyperlinked, so that when ever the user click on it, we will take them to their twitter page. Also it was a pain to always run this application by pressing F5, then it would open in a browser you would have to right click uninstall and install it again to see any changes. All this and yet we were not able to debug it :( Now there is a solution for this to run a silverlight application directly out of browser and yet have the debug feature. Super cool, here is how. Right on the Silverlight project and go to debug and then select the Out-Of-Browser application option and choose the *.Web project. Then just right click on the SL project and set as Startup Project. There you go, now every time you press F5, it will automatically run out of browser and still have the debug options. I go to know about this after some binging. Now let us jump to the core straight away. 1) To get the user id hyperlinked, we need to have a DataGridTemplateColumn and within that have a HyperLinkButton. The code for this will  be <data:DataGridTemplateColumn> <data:DataGridTemplateColumn.CellTemplate> <DataTemplate> <HyperlinkButton Click="HyperlinkButton_Click" Content="{Binding UserName}" TargetName="_blank" ></HyperlinkButton> </DataTemplate> </data:DataGridTemplateColumn.CellTemplate> </data:DataGridTemplateColumn> 2) Now let us look at how we are getting this done by looking into HyperlinkButton_Click event handler. There we will dynamically set the NavigateUri to the twitter page. I tried to do this using some binding, eval like stuff as in ASP.NET, but no luck! private void HyperlinkButton_Click(object sender, RoutedEventArgs e) { HyperlinkButton hb = (HyperlinkButton)e.OriginalSource; hb.NavigateUri = new Uri("http://twitter.com/" + hb.Content.ToString(), UriKind.Absolute); } 3) Now we need to switch on our Timer right in the OnNavigated to event on our SL page. So we need to modify our OnNavigated event to some thing like below: protected override void OnNavigatedTo(NavigationEventArgs e) { image1.Source = new BitmapImage(new Uri(GlobalVariable.profileImage, UriKind.Absolute)); this.Title = GlobalVariable.getUserName() + " - Home"; if (!GlobalVariable.isLoggedin()) this.NavigationService.Navigate(new Uri("/Login", UriKind.Relative)); else { currentGrid = "Timeline-Grid"; TwitterCredentialsSubmit(); myDispatcherTimer.Interval = new TimeSpan(0, 0, 0, 60, 0); myDispatcherTimer.Tick += new EventHandler(Each_Tick); myDispatcherTimer.Start(); } } I use a global string – here it is currentGrid variable to indicate what is bound in the datagrid so that after every timer tick, I can rebind the latest data to it again. Like I will only rebind the friends timeline again if the data grid currently holds it and I’ll only rebind the respective list status again in the data grid, if already a list status is bound to the data grid. In the above timer code, its set to trigger the Each_Tick event handler every 1 minute (60 seconds). TimeSpan takes in (days, hours, minutes, seconds, milliseconds). 4) Now we need to set the list name in the currentGrid variable when a list button is clicked. So add the code line below to the list button event handler currentGrid = currentList = b.Content.ToString(); 5) Now let us see how Each_Tick event handler is implemented. public void Each_Tick(object o, EventArgs sender) { if (!currentGrid.Equals("Timeline-Grid")) getListStatuses(currentGrid); else { WebRequest.RegisterPrefix("https://", System.Net.Browser.WebRequestCreator.ClientHttp); WebClient myService = new WebClient(); myService.AllowReadStreamBuffering = true; myService.UseDefaultCredentials = false; myService.Credentials = new NetworkCredential(GlobalVariable.getUserName(), GlobalVariable.getPassword()); myService.DownloadStringCompleted += new DownloadStringCompletedEventHandler(TimelineRequestCompleted); myService.DownloadStringAsync(new Uri("https://twitter.com/statuses/friends_timeline.xml")); } } If the data grid hold friends timeline, I just use the same bit of code we had already to bind the friends timeline to the data grid. Copy Paste. But if it is some list timeline that is bound in the datagrid, I then call the getListStatus method with the currentGrid string which will actually be holding the list name. 6) I wanted to make the hyperlinks inside the status message as hyperlinks and when the user clicks on it, we can then open that link. I tried using a convertor and using a regex to recognize a url and wrap it up with a href, but that is not gonna work in silverlight textblock :( Anyways that convertor code is in the zip file. 7) You can get the complete project files from here. 8) Please comment below for your doubts, suggestions, improvements. I will try to reply as early as possible. Thanks for all your support. Technorati Tags: Silverlight 4,Datagrid,Twitter API,Silverlight Timer

  • Silverlight 4 Twitter Client &ndash; Part 5

    - by Max
    In this post, we will look at implementing the following in our twitter client - displaying the profile picture in the home page after logging in. So to accomplish this, we will need to do the following steps. 1) First of all, let us create another field in our Global variable static class to hold the profile image url. So just create a static string field in that. public static string profileImage { get; set; } 2) In the Login.xaml.cs file, before the line where we redirect to the Home page if the login was successful. Create another WebClient request to fetch details from this url - .xml">http://api.twitter.com/1/users/show/<TwitterUsername>.xml I am interested only in the “profile_image_url” node in this xml string returned. You can choose what ever field you need – the reference to the Twitter API Documentation is here. 3) This particular url does not require any authentication so no need of network credentials for this and also the useDefaultCredentials will be true. So this code would look like. WebRequest.RegisterPrefix("http://", System.Net.Browser.WebRequestCreator.ClientHttp); WebClient myService = new WebClient(); myService.AllowReadStreamBuffering = myService.UseDefaultCredentials = true; myService.DownloadStringCompleted += new DownloadStringCompletedEventHandler(TimelineRequestCompleted_User);) myService.DownloadStringAsync(new Uri("http://api.twitter.com/1/users/show/" + TwitterUsername.Text + ".xml")); 4) To parse the xml file returned by this and get the value of the “profile_image_url” node, the LINQ code will look something like XDocument xdoc; xdoc = XDocument.Parse(e.Result); var answer = (from status in xdoc.Descendants("user") select status.Element("profile_image_url").Value); GlobalVariable.profileImage = answer.First().ToString(); 5) After this, we can then redirect to Home page completing our login formalities. 6) In the home page, add a image tag and give it a name, something like <Image Name="image1" Stretch="Fill" Margin="29,29,0,0" Height="73" VerticalAlignment="Top" HorizontalAlignment="Left" Width="73" /> 7) In the OnNavigated to event in home page, we can set the image source url as below image1.Source = new BitmapImage(new Uri(GlobalVariable.profileImage, UriKind.Absolute)); Hope this helps.

  • Why does the OAuth Unauthorized Error (401) happen?

    - by ming yeow
    Sometimes an Twitter OAuth is successfully executed, but an unauthorized error is thrown. I get about 50 of these on a daily basis. It is worrying, because I have no idea how that might be reproduced. What are the different cases where this error happens, and how can this be fixed or prevented?

  • puppet rspec no such file to load -- rspec-puppet (LoadError)

    - by Vorsprung
    I have no prior experience at all of ruby. I am not interested in ruby (and so have no knowledge of rails etc) as such but am using puppet to manage a group of servers. I have written some modules and the rspec-puppet system looks like it would be very useful. However, I cannot get rspec-puppet to work I am using Ubuntu LTS 10.04 I have installed puppet rspec using the directions on their web page What I actually did apt-get install rubygems # (installs 1.8) gem install rspec-expectations gem install rspec-puppet I also installed librspec-ruby1.8 Then I ran rspec-puppet-init in a puppet module directory I'd already made (it's a working puppet module) I made a file as defined in the tutorial $ more spec/defines/rule_spec.rb require 'spec_helper' describe 'vanusers::rule' do let(:title) { 't1' } it { should contain_class('vanusers::JamieA') } end but when I try and run it there is a mysterious dependancy issue $ spec spec/defines/rule_spec.rb /home/jamie/git/puppet/modules/vanusers/spec/spec_helper.rb:1:in `require': no such file to load -- rspec-puppet (LoadError) from /home/jamie/git/puppet/modules/vanusers/spec/spec_helper.rb:1 from ./spec/defines/rule_spec.rb:1:in `require' from ./spec/defines/rule_spec.rb:1 from /usr/lib/ruby/1.8/spec/runner/example_group_runner.rb:15:in `load' from /usr/lib/ruby/1.8/spec/runner/example_group_runner.rb:15:in `load_files' from /usr/lib/ruby/1.8/spec/runner/example_group_runner.rb:14:in `each' from /usr/lib/ruby/1.8/spec/runner/example_group_runner.rb:14:in `load_files' from /usr/lib/ruby/1.8/spec/runner/options.rb:132:in `run_examples' from /usr/lib/ruby/1.8/spec/runner/command_line.rb:9:in `run' from /usr/bin/spec:3 Here is the solution I came up with in the end:: apt-get install rubygems gem install rspec-expectations rspec-puppet puppet-lint puppetlabs_spec_helper so your path picks up the gem stuff export PATH=/var/lib/gems/1.8/bin:$PATH cd into module and rm spec/spec_helper.rb rspec-puppet-init replace Rakefile with require 'rake' require 'rspec/core/rake_task' require 'puppetlabs_spec_helper/rake_tasks' Then "rake spec" to run tests or "rake lint" to check files http://sysadvent.blogspot.co.uk/2013/12/day-22-getting-started-testing-your.html was an excellent source of info

  • Tokenizing Twitter Posts in Lucene

    - by Amaç Herdagdelen
    Hello, My question in a nutshell: Does anyone know of a TwitterAnalyzer or TwitterTokenizer for Lucene? More detailed version: I want to index a number of tweets in Lucene and keep the terms like @user or #hashtag intact. StandardTokenizer does not work because it discards the punctuation (but it does other useful stuff like keeping domain names, email addresses or recognizing acronyms). How can I have an analyzer which does everything StandardTokenizer does but does not touch terms like @user and #hashtag? My current solution is to preprocess the tweet text before feeding it into the analyzer and replace the characters by other alphanumeric strings. For example, String newText = newText.replaceAll("#", "hashtag"); newText = newText.replaceAll("@", "addresstag"); Unfortunately this method breaks legitimate email addresses but I can live with that. Does that approach make sense? Thanks in advance! Amaç

  • twitter bootstrap typeahead 2.0.4 ajax error

    - by Adam Levitt
    I have the following code which definitely returns a proper data result if I use the 2.0.0 version, but for some reason bootstrap's typeahead plugin is giving me an error. I pasted it below the code sample: <input id="test" type="text" /> $('#test').typeahead({ source: function(typeahead, query) { return $.post('/Profile/searchFor', { query: query }, function(data) { return typeahead.process(data); }); } }); When I run this example I'm getting a jQuery bug that says the following: ** item is undefined matcher(item=undefined)bootst...head.js (line 104) <br/>(?)(item=undefined)bootst...head.js (line 91) <br/>f(a=function(), b=function(), c=false)jquery....min.js (line 2) <br/>lookup(event=undefined)bootst...head.js (line 90) <br/>keyup(e=Object { originalEvent=Event keyup, type="keyup", timeStamp=145718131, more...})bootst...head.js (line 198) <br/>f()jquery....min.js (line 2) <br/>add(c=Object { originalEvent=Event keyup, type="keyup", timeStamp=145718131, <br/>more...})jquery....min.js (line 3) <br/>add(a=keyup charCode=0, keyCode=70)jquery....min.js (line 3) <br/>[Break On This Error] <br/>return item.toLowerCase().indexOf(this.query.toLowerCase())** Any thoughts? ... The same code works in the 2.0.0 version of the plugin, but fails to write to my knockout object model.
