    I want to share a different solution i made for my Rails Application that i hope can help others to develop the same thing in their framework.

    I've build my application front-end in Angular - one-page app - so it can change to different content with each of its own share button with different image, description, and title without reloading.

    But because of this i had the same trouble with the share button data as well.

    The solution i found was to look for the request headers and check if they are coming from Facebook. If this is true, then render a different view only with a head tag with the corresponding content meta data Facebook reads.

    Controller and custom view with meta-data for each content:


    #works_controller.rb
      def index
        ...
        agent = request.headers["HTTP_USER_AGENT"].downcase
        if agent.include?("facebook")
          render_facebook_share_info @current_work, params
          return
        end
        ...
      end
    

    Then i set the variables

      def render_facebook_share_info work, params_passed
        @currentUrl = URL + "/themes/#{params_passed[:theme_id]}/works/#{params_passed[:work_id]}"
        @currentImage = work.share_image.present? ? work.share_image.url : work.cover_image.url 
        @currentTitle = work.title 
        description = work.share_description.present? ? work.share_description : "" 
        @currentDescription = description
        render 'shared_facebook_data', layout: false 
      end
    

    And then i render the variables in the view:

    <!-- shared_facebook_data.html.erb -->
    <head>
      <meta property="og:url" content="<%=@currentUrl %>" />
      <meta property="og:type" content="article" />
      <meta property="og:site_name" content="Papercut Odyssey" />
      <meta property="og:title" content="<%= @currentTitle %>" />
      <meta property="og:description" content="<%= @currentDescription %>" />
      <meta property="og:image" content="<%= @currentImage %>" />
    </head>
    

    Dynamic link for each content

    So now i can use a link with the work id for @current_work in the facebook.com/sharer.php URL, and Facebook will be triggered into 'thinking' it has its own page with its own meta-data.

    Mine was (in Angular):

    <a [attr.href]="'https://www.facebook.com/sharer.php?u=my_domain.com/' + theme.id + '/works/' + current_work.id" target="_blank">Share on Facebook</a>
    

    Hope it helps someone - it worked for me.

    It is fairly easy to do - you just associate to each of the buttons the URL of the post page instead the URL of the landing page.

    The implementation should be similar to the following (of course you should loop through your posts instead):

    <ul>
        <li>
            <h3>Post #1</h3>
            <div class="fb-like" data-href="https://google.com" data-text="Check out Google!" data-layout="button_count" data-action="like" data-show-faces="false" data-share="false"></div>        
            <a href="https://twitter.com/share" class="twitter-share-button" data-url="http://google.com">Tweet</a>
        </li>      
        <li>
            <h3>Post #2</h3>
            <div class="fb-like" data-href="https://facebook.com" data-text="Check out Facebook!" data-layout="button_count" data-action="like" data-show-faces="false" data-share="false"></div>  
            <a href="https://twitter.com/share" class="twitter-share-button" data-url="http://facebook.com">Tweet</a>
        </li>     
        <li>
            <h3>Post #3</h3>
            <div class="fb-like" data-href="https://stackoverflow.com" data-text="Check out Stackoverflow!" data-layout="button_count" data-action="like" data-show-faces="false" data-share="false"></div>  
            <a href="https://twitter.com/share" class="twitter-share-button" data-url="http://stackoverflow.com">Tweet</a>
        </li>     
    </ul>
    
    <script>!function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0],p=/^http:/.test(d.location)?'http':'https';if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src=p+'://platform.twitter.com/widgets.js';fjs.parentNode.insertBefore(js,fjs);}}(document, 'script', 'twitter-wjs');</script>
    <div id="fb-root"></div>
    <script>(function(d, s, id) {
      var js, fjs = d.getElementsByTagName(s)[0];
      if (d.getElementById(id)) return;
      js = d.createElement(s); js.id = id;
      js.src = "//connect.facebook.net/en_GB/sdk.js#xfbml=1&version=v2.0";
      fjs.parentNode.insertBefore(js, fjs);
    }(document, 'script', 'facebook-jssdk'));</script>

    Here is what I did.

    This code is for Twitter. Added once in HEAD html section:

    <script>window.twttr = (function(d, s, id) {
      var js, fjs = d.getElementsByTagName(s)[0],
        t = window.twttr || {};
      if (d.getElementById(id)) return t;
      js = d.createElement(s);
      js.id = id;
      js.src = "https://platform.twitter.com/widgets.js";
      fjs.parentNode.insertBefore(js, fjs);
    
      t._e = [];
      t.ready = function(f) {
        t._e.push(f);
      };
    
      return t;
    }(document, "script", "twitter-wjs"));</script>
    

    This code is for Facebook. Added once at the top of the BODY html section.

    <div id="fb-root"></div>
    <script>(function(d, s, id) {
      var js, fjs = d.getElementsByTagName(s)[0];
      if (d.getElementById(id)) return;
      js = d.createElement(s); js.id = id;
      js.src = "//connect.facebook.net/en_US/sdk.js#xfbml=1&version=v2.3";
      fjs.parentNode.insertBefore(js, fjs);
    }(document, 'script', 'facebook-jssdk'));
    </script>
    

    The HTML for the homepage list with each item having it's own Twitter and FB buttons. Each referencing a the specific post page.

    <ul>
      <li>
        <h3>Post #1</h3>
        <div class="fb-share-button" data-href="https://example.com/post/1" 
             data-layout="button"></div>  
        <a href="https://twitter.com/share" class="twitter-share-button" 
           data-url="https://example.com/post/1">Tweet</a>
      </li>
      <li>
        <h3>Post #2</h3>
        <div class="fb-share-button" data-href="https://example.com/post/2" 
             data-layout="button"></div>  
        <a href="https://twitter.com/share" class="twitter-share-button" 
           data-url="https://example.com/post/2">Tweet</a>
      </li>
    </ul>
