  • The complete guide on tracking your websites and web apps into multiple Piwiks and how to do it easily & efficiently

    23 février 2017, par InnoCraft — Community, Development

    Getting the tracking of your website and apps right is crucial to your success as you need to ensure the measured data is meaningful and correct. That’s why we, at InnoCraft, help our clients setting up their web tracking and digital measurement strategy. Some challenges include tracking your analytics data into multiple Piwik services as well as the tracking of single-page websites and web applications (covered in a previous article). In this blog post, we explain how to track your data into multiple Piwik websites correctly.

    Embedding the tracking code

    First of all you need to embed your JavaScript tracking code into your website or app as usual. If you haven’t done this yet : Log in to your Piwik, click on “Administration” in the top right and go to “Tracking Code”. There you have various options to adjust your tracking code to your needs.

    Tracking the same data into different websites

    Let’s assume you have set up the regular JavaScript tracking code and you want to track the same data into a second Piwik website. This second Piwik website can be either on the same Piwik installation or on a different Piwik. To do this, add the following line to your tracking code :

    _paq.push(['addTracker', 'https://$yourPiwikDomain/piwik.php', idSite]);

    It should look like this :

    var u = '//$yourPiwikDomain';
    _paq.push(['addTracker', u + '/piwik.php', var idSite = 2]); // adds an additional tracker
    _paq.push(['setSiteId', '1']); // configures your regular Piwik tracker
    _paq.push(['setTrackerUrl', u + 'piwik.php']);

    This will track the same data into website 1 and website 2 of your Piwik installation. You can also change the domain in addTracker to point it to a different Piwik installation :

    _paq.push(['addTracker', '//$differentPiwikDomain/piwik.php', var idSite = 2]);

    All Piwik tracker methods that you call afterwards will be applied to all trackers. Say you call _paq.push(['disableCookies']); _paq.push(['trackPageView']);, then both methods will be called on all tracker instances assuring they will behave the same and will track the same data into both Piwik websites.

    Tracking different data into different websites

    If you want to track only certain data into one website, and different data into an additional website, you need to configure the trackers differently. For example, you want to enable link tracking only for one tracker, but not for the other. The problem is that calling _paq.push(['enableLinkTracking']); enables link tracking on all of your trackers. To workaround this limitation, you can configure your trackers differently like this :

    window.piwikAsyncInit = function () {
       Piwik.on('TrackerSetup', function (tracker) {
         if (tracker.getSiteId() == 2
            || tracker.getTrackerUrl() === '//$yourPiwikDomain/piwik.php') {
             tracker.enableLinkTracking();
            }
       });
    };

    Now it enables link tracking only for the tracker that is configured for a certain website ID or Piwik domain.

    Accessing a previously generated tracker instance

    When you configure a tracker via _paq.push, you create a so called “Async tracker” because Piwik will be loaded asynchronously and create the tracker instance as soon as it is loaded. If you need to get the instance of such a tracker, you can use the method Piwik.getAsyncTracker(trackerUrl, idSite). This can be useful if you have a single-page website and want to track different data into different websites :

    window.addEventListener('hashchange', function() {
       if ('undefined' === typeof Piwik) {
           // Piwik might not be loaded yet
           return;
       }
       var tracker1 = Piwik.getAsyncTracker('//$yourPiwikDomain/piwik.php', var idSite = 1);
       var tracker2 = Piwik.getAsyncTracker('//$yourPiwikDomain/piwik.php', var idSite = 2);
       tracker1.setCurrentUrl('/' + window.location.hash.substr(1));
       tracker2.setCurrentUrl('/mywebsite/' + window.location.hash.substr(1));
    });

    Tracking different data into multiple Piwik installations without using “_paq”

    Some users prefer to not use _paq.push and instead directly create tracker instances themselves using the method Piwik.getTracker(trackerUrl, idSite) like this :

    window.piwikAsyncInit = function () {
       var tracker1 = Piwik.getTracker('//$yourPiwikdomain/piwik.php', var idSite = 1);
       tracker1.disableCookies();
       var tracker2 = Piwik.getTracker('//$yourPiwikdomain/piwik.php', var idSite = 2);
       tracker2.enableLinkTracking();

       tracker1.trackPageView();
       tracker2.trackPageView();
    };

    We usually don’t recommend creating trackers manually as it is more complicated and you need to make sure to configure trackers in the right order. For example to prevent the setting of any cookies, it is recommended to call disableCookies before calling any other methods. If you want to create your trackers manually and you use any of the following methods, make sure to call them in this order :

    disableCookies(), setAPIUrl(), enableCrossDomainLinking(), setCookiePath(), setCookieDomain(), setDomains(), setUserId(), enableLinkTracking()

    Roll-Up Reporting – the easy and efficient way

    Often users track data into multiple websites because they need aggregated data over all their websites. They want to see all statistics for a single website, but also which pages were viewed across all their websites, or how much traffic they got from a specific website or search engine across all websites. This means they add a second tracker to all their websites and track data not only into the regular Piwik website, but also into one additional website that gives them statistics over all websites. This has several disadvantages :

    • Complexity in getting the tracking code right and the time needed to integrate and maintain it
    • Slower website performance because everything needs to be tracked into several websites. This can decrease your conversions and sales
    • Slower Piwik performance because it has to handle twice as much traffic. This means tracking becomes slower, generating the report becomes slower, and the database gets twice as big

    Luckily, there is a better solution called Roll-Up Reporting. With Roll-Up Reporting, you can get aggregated data over all websites and / or for a group of websites without any of these disadvantages. It lets you create as many Roll-Ups as you wish and you can choose which websites’ data should be aggregated together into a new website.

    We had customers who were able to remove one Piwik tracker because of this feature which resulted in less server costs, a faster website, and a faster Piwik. On top of all these advantages, it also lets you view the Visitor Log, Real-time Map, and other widgets and reports across several websites.

  • How do I get videos to upload using ruby on rails carrierwave-video ?

    9 juillet 2016, par Eric

    Updated as of July 9, 2016

    I tried to follow the instructions on the github website for the video uploader process using carrierwave-video gem but get an error that says the file or directory mmpeg -i doesn’t exist.

    The upload path for images functions correctly, just not the video one.

    I have added all of the following code necessary to help solve the error and minified as much as i possibly could.

    Video uploader code using carrierwave

    class VideoUploader < CarrierWave::Uploader::Base

     include CarrierWave::Video
     storage :file

     version :mp4 do
       process :encode_video => [:mp4, resolution: "100x100"]
     end

     def store_dir
       "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
     end
    end

    Here is the movie controller code that handles uploading of videos

    class MoviesController &lt; ApplicationController
      include MoviesHelper

      def index
         mode "index"
      end

      def show
         mode "show"
      end

      def new
         mode "new"
      end

      def edit
         mode "edit"
      end

      def create
         mode "create"
      end

      def update
         mode "update"
      end

      def destroy
         mode "destroy"
      end

      def review
         mode "review"
      end

      def approve
         mode "approve"
      end

      def deny
         mode "deny"
      end
    end

    Here is the model data for the movie that goes with it

    class Movie &lt; ActiveRecord::Base
     attr_accessible :created_on, :description, :maintenance, :reviewed, :subplaylist_id, :title, :user_id, :video, :remote_video_url
     belongs_to :user
     belongs_to :subplaylist
     mount_uploader :video, VideoUploader
    end

    Here is where the movie is supposed to be displayed but it is not working

    &lt;% provide(:title, "Movie: Where movies are made!") %>
    &lt;% provide(:keywords, "movies, video") %>
    &lt;% provide(:description, "This is the place where users showcase their wonderful video talent.") %>
    <p>&lt;%= notice %></p>
    <h1 class="pageheader">&lt;%= @movie.title %></h1>
    <br />
    <p class="pagetext">&lt;%= video_tag(@movie.video_url.to_s, controls: true, class: "imagebox") %></p>
    <p class="pagetext">&lt;%= @movie.description %></p>

    <p class="pagetext">Owner: &lt;%= getType(@movie.user) %>&lt;%= link_to @movie.user.vname, user_path(@movie.user) %></p>
    <br />
    <p class="pagetext">&lt;%= link_to 'Back', mainplaylist_subplaylist_path(@subplaylist.mainplaylist, @movie.subplaylist) %></p>

    Here is where the movie new action is

    &lt;% provide(:title, "Movie: Create new movies here!") %>
    &lt;% provide(:description, "New movies are uploaded only to the site when the movie gets approved.") %>
    <h1 class="pagetextheader">New movie</h1>
    &lt;%= render 'form' %>
    <p class="pagetext">&lt;%= link_to 'Back', mainplaylist_subplaylist_path(@subplaylist.mainplaylist, @subplaylist) %></p>

    Here is where the movies forum parameters are

    &lt;%= form_for([@subplaylist, @movie], :html=>{:multipart => true}) do |f| %>
     &lt;% if @movie.errors.any? %>
       <div>
         <h2>&lt;%= pluralize(@movie.errors.count, "error") %> prohibited this movie from being saved:</h2>

         <ul>
         &lt;% @movie.errors.full_messages.each do |msg| %>
           <li>&lt;%= msg %></li>
         &lt;% end %>
         </ul>
       </div>
     &lt;% end %>
     <br />
     <div class="pagetext">
       &lt;%= f.label :title %><br />
       &lt;%= f.text_field :title %>
     </div>
     <div class="pagetext">
       &lt;%= f.file_field :video %>
     </div>
     <div class="pagetext">
       &lt;%= f.label :remote_video_url, "or video URL" %><br />
       &lt;%= f.text_field :remote_video_url %>
     </div>
     <div class="pagetext">
       &lt;%= f.label :description %><br />
       &lt;%= f.text_area :description %>
     </div>
     <div class="pagetext">
       &lt;%= f.submit %>
     </div>
     <br />
    &lt;% end %>

    Error message

  • How do I get videos to upload using carrierwave-video ?

    10 juillet 2016, par Eric

    I tried to follow the instructions on github to upload using carrierwave-video, but get an error that says the file or directory mmpeg -i doesn’t exist.

    The upload path for images is correct, just not the video one.

    I added all of the following code necessary to help solve the error and minified as much as I possibly could.

    This is the video uploader code using carrierwave :

    class VideoUploader &lt; CarrierWave::Uploader::Base

     include CarrierWave::Video
     storage :file

     version :mp4 do
       process :encode_video => [:mp4, resolution: "100x100"]
     end

     def store_dir
       "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
     end
    end

    This is the movie controller code that handles uploading of videos :

    class MoviesController &lt; ApplicationController
      include MoviesHelper

      def index
         mode "index"
      end

      def show
         mode "show"
      end

      def new
         mode "new"
      end

      def edit
         mode "edit"
      end

      def create
         mode "create"
      end

      def update
         mode "update"
      end

      def destroy
         mode "destroy"
      end

      def review
         mode "review"
      end

      def approve
         mode "approve"
      end

      def deny
         mode "deny"
      end
    end

    This is the model data for the movie that goes with it :

    class Movie &lt; ActiveRecord::Base
     attr_accessible :created_on, :description, :maintenance, :reviewed, :subplaylist_id, :title, :user_id, :video, :remote_video_url
     belongs_to :user
     belongs_to :subplaylist
     mount_uploader :video, VideoUploader
    end

    This is where the movie is supposed to be displayed but it is not working :

    &lt;% provide(:title, "Movie: Where movies are made!") %>
    &lt;% provide(:keywords, "movies, video") %>
    &lt;% provide(:description, "This is the place where users showcase their wonderful video talent.") %>
    <p>&lt;%= notice %></p>
    <h1 class="pageheader">&lt;%= @movie.title %></h1>
    <br />
    <p class="pagetext">&lt;%= video_tag(@movie.video_url.to_s, controls: true, class: "imagebox") %></p>
    <p class="pagetext">&lt;%= @movie.description %></p>
    <p class="pagetext">Created on: &lt;%= @movie.created_on.strftime("%B-%d-%Y") %></p>
    <p class="pagetext">Owner: &lt;%= getType(@movie.user) %>&lt;%= link_to @movie.user.vname, user_path(@movie.user) %></p>
    <br />
    <p class="pagetext">&lt;%= link_to 'Back', mainplaylist_subplaylist_path(@subplaylist.mainplaylist, @movie.subplaylist) %></p>

    This is where the movie new action is :

    &lt;% provide(:title, "Movie: Create new movies here!") %>
    &lt;% provide(:description, "New movies are uploaded only to the site when the movie gets approved.") %>
    <h1 class="pagetextheader">New movie</h1>
    &lt;%= render 'form' %>
    <p class="pagetext">&lt;%= link_to 'Back', mainplaylist_subplaylist_path(@subplaylist.mainplaylist, @subplaylist) %></p>

    This is where the movies forum parameters are :

    &lt;%= form_for([@subplaylist, @movie], :html=>{:multipart => true}) do |f| %>
     &lt;% if @movie.errors.any? %>
       <div>
         <h2>&lt;%= pluralize(@movie.errors.count, "error") %> prohibited this movie from being saved:</h2>

         <ul>
         &lt;% @movie.errors.full_messages.each do |msg| %>
           <li>&lt;%= msg %></li>
         &lt;% end %>
         </ul>
       </div>
     &lt;% end %>
     <br />
     <div class="pagetext">
       &lt;%= f.label :title %><br />
       &lt;%= f.text_field :title %>
     </div>
     <div class="pagetext">
       &lt;%= f.file_field :video %>
     </div>
     <div class="pagetext">
       &lt;%= f.label :remote_video_url, "or video URL" %><br />
       &lt;%= f.text_field :remote_video_url %>
     </div>
     <div class="pagetext">
       &lt;%= f.label :description %><br />
       &lt;%= f.text_area :description %>
     </div>
     <div class="pagetext">
       &lt;%= f.submit %>
     </div>
     <br />
    &lt;% end %>
