  • twitter streaming api instead of search api

    - by user1711576
    I am using twitters search API to view all the tweets that use a particular hashtag I want to view. However, I want to use the stream function, so, I only get recent ones, and so, I can then store them. <?php global $total, $hashtag; $hashtag = $_POST['hash']; $total = 0; function getTweets($hash_tag, $page) { global $total, $hashtag; $url = 'http://search.twitter.com/search.json?q='.urlencode($hash_tag).'&'; $url .= 'page='.$page; $ch = curl_init($url); curl_setopt ($ch, CURLOPT_RETURNTRANSFER, TRUE); $json = curl_exec ($ch); curl_close ($ch); echo "<pre>"; $json_decode = json_decode($json); print_r($json_decode->results); $json_decode = json_decode($json); $total += count($json_decode->results); if($json_decode->next_page){ $temp = explode("&",$json_decode->next_page); $p = explode("=",$temp[0]); getTweets($hashtag,$p[1]); } } getTweets($hashtag,1); echo $total; ?> The above code is what I have been using to search for the tweets I want. What do I need to do to change it so I can stream the tweets instead? I know I would have to use the stream url https://api.twitter.com/1.1/search/tweets.json , but what do I need to change after that is where I don't know what to do. Obviously, I know I'll need to write the database sql but I want to just capture the stream first and view it. How would I do this? Is the code I have been using not any good for just capturing the stream?

  • Grails: can remoteField update multiple fields?

    - by Michael Bavin
    Hi, Assume i have a book entity with an isbn field. When entered a isbn number, i want 2 fields to be updated: title and author. My controller looks like this: def ajaxGetBook = { def book = Book.findByIsbn(params.isbn) if(book==null) book = new Book() render book as JSON } So my call works, and i get a full JSON Book. Now i would like to update 2 texfields by the update attribute <g:remoteField action="ajaxGetBook" update="title" name="isbn" value="${bookInstance?.book?.isbn}" paramName="isbn"/> Now the title field gets updated with the full book object, so that doesn't work. Is it possible to update field title with only the JSON book.title? Is it possible to update more fields at once? I could render book.title as JSON but that works for only one field. Thank you

  • Can an appdomain in C# be restricted to one directory?

    - by Caerbanog
    I am developing a plugin host. The plugins should have as little trust as they need, however I want to have the possibility for a plugin to read and write files. Can the AppDomain where the assembly will be loaded be restricted to have access to only one directory for reading and writing? Other options and ways to go about this are also appreciated like for example easy ways to stream file data from the host to the plugin (reading) and from the plugin to the host (writing). If its relevant: I am using the MAF infrastructure for the plugins. http://msdn.microsoft.com/en-us/library/bb384200.aspx

  • receiving OPTIONS instead of GET requests?

    - by Urs
    Hi, all I want to achieve is to implement a servlet providing a json feed for my fullcalendar application. When I inspect http://arshaw.com/js/fullcalendar/examples/json.html with Bugzilla, I see that GET-requests are sent to receive the json feed. However, when I use this example within my scenario, fullcalendar seems to send OPTIONS-requests. The only difference is that I replaced "events: "json-events.php" with "http://localhost:8080/CalendarServletTest/HelloWorldServlet" (the url of my servlet). What do I miss? or is this really a bug?

    $.ajax({ url: "plugin.js", dataType: 'script', cache: true, success: function() { alert('loaded'); }}); 1) I can't get the script to load, probably due to incorrect path, but how do I determine the correct path?

  • What is the best way to handle dynamic content_type in Sinatra

    - by lusis
    I'm currently doing the following but it feels "kludgy": module Sinatra module DynFormat def dform(data,ct) if ct == 'xml';return data.to_xml;end if ct == 'json';return data.to_json;end end end helpers DynFormat end My goal is to plan ahead. Right now we're only working with XML for this particular web service but we want to move over to JSON as soon as all the components in our stack support it. Here's a sample route: get '/api/people/named/:name/:format' do format = params[:format] h = {'xml' => 'text/xml','json' => 'application/json'} content_type h[format], :charset => 'utf-8' person = params[:name] salesperson = Salespeople.find(:all, :conditions => ['name LIKE ?', "%#{person}%"]) "#{dform(salesperson,format)}" end It just feels like I'm not doing it the best way possible.

  • Several modules in a package importing one common module

    - by morpheous
    I am writing a python package. I am using the concept of plugins - where each plugin is a specialization of a Worker class. Each plugin is written as a module (script?) and spawned in a separate process. Because of the base commonality between the plugins (e.g. all extend a base class 'Worker'), The plugin module generally looks like this: import commonfuncs def do_work(data): # do customised work for the plugin print 'child1 does work with %s' % data In C/C++, we have include guards, which prevent a header from being included more than once. Do I need something like that in Python, and if yes, how may I make sure that commonfuncs is not 'included' more than once?

  • Using the standard OBJECT tag, how can I display a java applet with automatic prompts to install Java and with fallback content?

    - by CB
    This is the code i'm currently using: (note - %s is replaced on the server side) <!--[if !IE]>--> <object type="application/x-java-applet" width="300" height="300" > <!--<![endif]--> <!--[if IE]> <object classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93" codebase="http://java.sun.com/update/1.6.0/jinstall-6u22-windows-i586.cab" type="application/x-java-applet" width="300" height="300" > <!--><!-- <![endif]--> <param name="codebase" value="/media/vnc/" > <param name="archive" value="TightVncViewer.jar" /> <param name="code" value="com.tightvnc.vncviewer.VncViewer" /> <param name="port" value="%s" /> <param name="Open New Window" value="yes" /> </object> When Java is installed, this works perfectly in both IE and Firefox. When Java is not installed, IE and Firefox both correctly prompt for an autodownload of Java 1.6 from the codebase line. (IE via the activex url given firefox via the Plugin Finder Service) Now, suppose I want fallback content to be shown if the plugin isn't installed, say a simple message like "Get Java". From reading the specs, i'd assume this should not change the plugin finding prompt - that is, rendering the fallback should be seen as a failure to render the object tag. Thus, I should still get the plugin finder service prompting me to install Java. Instead, simply adding a single character to the innerHTML of the object element causes Firefox to no longer prompt. Test this by visiting data:text/html,<object type='application/x-java-applet'>Java failed to load</object>. How can I keep firefox prompting to install Java while providing fallback content? URL to test Firefox's Java Plugin Finder Service: data:text/html,<object type='application/x-java-applet'/>

I checked the firebug 'net' tab and indeed i get a succesful response from the server of "jsonp1272724228884( {} );" Any ideas?

  • Java Authenticator on a per connection basis?

    - by Martijn Laarman
    I'm building an Eclipse plugin that talks to a REST interface which uses Basic Authentication. When the authentication fails I would like to popup my plugin's settings dialog and retry. Normally I could use the static Authenticator.setDefault() to setup an authenticator for all HttpURLConnection's for this, but since I am writing a plugin I don't want to overwrite Eclipse's default Authenticator (org.eclipse.ui.internal.net.auth); I thought of setting my custom Authenticator before loading and putting Eclipse's default back afterwards, but I imagine this will cause all sorts of race issues with multithreading so I quickly lost that notion. Google searches yield all sorts of results basically telling me it's not possible: The Java URLConnection API should have a setAuthenticator(Authenticator) method for making it easier to use this class in multi-threaded context where authentication is required. Source If applications contains few third party plugins and each plugin use its own Authenticator what we should do? Each invocation of "Authenticator.setDefault()" method rewrite previously defined Authenticator... Source Are there any different approaches that might help me overcome this issue?

  • Rails - Rendering a Partial without having to use "_" in front of the filename?

    - by bluedevil2k
    How do I render a partial without having to supply the "_" in front of the file name? Is there a parameter I can call to not use it? This problem popped up using RABL and Backbone - using RABL requires me to have a file in my views like "index.json.rabl". But, when I use embed the JSON right on the page load (as is usual with Backbone), I'm required to call the file "index.json.rabl". These 2 files are the exact same thing, just required to have different names. I'm looking to use just 1 file, "index.json.rabl" and force the render() function to look for that file name, without the "".

  • How do I find everything between two characters after a word using grep, without outputting the entire line?

    - by Nick Sweeting
    I am downlading the info.0.json file from xkcd and trying to parse just the alt text. I don't care if there are quotes around it or not. The problem it that the info.0.json file is all one line, and the alt text is in quotes after the word "alt=". Trying cat info.0.json | grep alt just returns the whole file (because it's all one line). What is the grep or sed code that will get me the alt text?

  • increasing speed and efficiency of ajax call

    - by user1048824
    I'm not the most disciplined dev, dont know standards and am self-taught so bear with me. I create stuff very logically and fast but not always using 'programming standards'. I have a mobile app using geolocation API. it gets thousands of places from my db and makes gmaps v3 markers for the ones around the user's current location. there is an ajax call from my JS to an aspx page that calls the database, makes a json string, and sends the json string to the javascript that then creates the google map markers. would i save time if the json string was in a flat file? im not sure if, generally speaking, accessing a sql db from an aspx page is faster than c# file i/o on a flat file with pre-rendered JSON. (of course, using the flat file, it would update everytime the db is updated)

  • Create rails record from two ids

    - by Michael Luby
    The functionality I'm trying to build allows Users to Visit a Restaurant. I have Users, Locations, and Restaurants models. Locations have many Restaurants. I've created a Visits model with user_id and restaurant_id attributes, and a visits_controller with create and destroy methods. Thing is, I can't create an actual Visit record. Any thoughts on how I can accomplish this? Or am I going about it the wrong way. Here's the code: Model: class Visit < ActiveRecord::Base attr_accessible :restaurant_id, :user_id belongs_to :user belongs_to :restaurant end View: <% @restaurants.each do |restaurant| %> <%= link_to 'Visit', location_restaurant_visits_path(current_user.id, restaurant.id), method: :create %> <% @visit = Visit.find_by_user_id_and_restaurant_id(current_user.id, restaurant.id) %> <%= @visit != nil ? "true" : "false" %> <% end %> Controller: class VisitsController < ApplicationController before_filter :find_restaurant before_filter :find_user def create @visit = Visit.create(params[:user_id => @user.id, :restaurant_id => @restaurant.id]) respond_to do |format| if @visit.save format.html { redirect_to location_restaurants_path(@location), notice: 'Visit created.' } format.json { render json: @visit, status: :created, location: @visit } else format.html { render action: "new" } format.json { render json: @visit.errors, status: :unprocessable_entity } end end end def destroy @visit = Visit.find(params[:user_id => @user.id, :restaurant_id => @restaurant.id]) @restaurant.destroy respond_to do |format| format.html { redirect_to location_restaurants_path(@restaurant.location_id), notice: 'Unvisited.' } format.json { head :no_content } end end private def find_restaurant @restaurant = Restaurant.find(params[:restaurant_id]) end def find_user @user = current_user end end
