Facebook plugin page in Rails Turbolinks doesn'

Question

in my Rails app I am loading Facebook plugin page, but because of turbolinks it doesnt load each page (only sometimes). I tried this script on this page , but now it never loads. What did I do?

I created facebook.coffee with this script:

$ ->
  loadFacebookSDK()
  bindFacebookEvents() unless window.fbEventsBound

bindFacebookEvents = ->
  $(document)
    .on('page:fetch', saveFacebookRoot)
    .on('page:change', restoreFacebookRoot)
    .on('page:load', ->
      FB?.XFBML.parse()
    )
  @fbEventsBound = true

saveFacebookRoot = ->
  if $('#fb-root').length
    @fbRoot = $('#fb-root').detach()

restoreFacebookRoot = ->
  if @fbRoot?
    if $('#fb-root').length
      $('#fb-root').replaceWith @fbRoot
    else
      $('body').append @fbRoot

loadFacebookSDK = ->
  window.fbAsyncInit = initializeFacebookSDK
  $.getScript("//connect.facebook.net/cs_CZ/sdk.js#xfbml=1&version=v2.6")

initializeFacebookSDK = ->
  FB.init
    appId  : 'YOUR_APP_ID'
    status : true
    cookie : true
    xfbml  : true

And then in my application.js i just require it.

In view I have this code:

<div id="fb-root"></div>
<div class="fb-page" data-href="https://www.facebook.com/mypage/" data-tabs="timeline" data-small-header="false" data-adapt-container-width="true" data-hide-cover="false" data-show-facepile="true"><div class="fb-xfbml-parse-ignore"><blockquote cite="https://www.facebook.com/mypage/"><a href="https://www.facebook.com/mypage/">MyPage</a></blockquote></div></div>

Facebook plugin page isn't loading. Don't you know why? I was looking on appId, but in plugin page its not included.

This worked for me ... Some sort of combination between Facebook's docs and the script on the page you linked

$ ->
  loadFacebookSDK()
  bindFacebookEvents() unless window.fbEventsBound

bindFacebookEvents = ->
  $(document)
    .on('page:fetch', saveFacebookRoot)
    .on('page:change', restoreFacebookRoot)
    .on('page:load', ->
      FB.XFBML.parse()
    )
  @fbEventsBound = true

saveFacebookRoot = ->
  if $('#fb-root').length
    @fbRoot = $('#fb-root').detach()

restoreFacebookRoot = ->
  if @fbRoot?
    if $('#fb-root').length
      $('#fb-root').replaceWith @fbRoot
    else
      $('body').append @fbRoot

loadFacebookSDK = ->
  ((d, s, id) ->
    js = d.getElementsByTagName(s)[0]
    fjs = d.getElementsByTagName(s)[0]
    return if d.getElementById(id)
    js = d.createElement(s)
    js.id = id
    js.src = "https://connect.facebook.net/es_LA/sdk.js#xfbml=1&version=v2.5"
    fjs.parentNode.insertBefore(js, fjs)
  )(document, 'script', 'facebook-jssdk')

initializeFacebookSDK = ->
  FB.init
    # appId : 'YOUR_APP_ID'
    status : true
    cookie : true
    xfbml : true

The difference is in the loadFacebookSDK function. Notice that as I commented in the question, $.getScript() removes the query/parameters part of the request.

For anyone else who finds this question, I found this gist, which solves the problem: https://gist.github.com/6temes/52648dc6b3adbbf05da3942794b97a00

// FacebookSDK
// https://developers.facebook.com/docs/plugins/page-plugin/
(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=v2.8";
  fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk')); // Replace 'facebook-jssdk' with your page id.

// Compatibility with Turbolinks 5
(function($) {
  var fbRoot;

  function saveFacebookRoot() {
    if ($('#fb-root').length) {
      fbRoot = $('#fb-root').detach();
    }
  };

  function restoreFacebookRoot() {
    if (fbRoot != null) {
      if ($('#fb-root').length) {
        $('#fb-root').replaceWith(fbRoot);
      } else {
        $('body').append(fbRoot);
      }
    }

    if (typeof FB !== "undefined" && FB !== null) { // Instance of FacebookSDK
      FB.XFBML.parse();
    }
  };

  document.addEventListener('turbolinks:request-start', saveFacebookRoot)
  document.addEventListener('turbolinks:load', restoreFacebookRoot)
}(jQuery));
