Konvertieren von datatables-Javascript zu verwenden Opal in Rails-app

Ich bin mit dem ajax-datatables-Schienen. Unten ist die JS für meine Datentabelle. Ich möchte konvertieren Sie das javascript in eine äquivalente Opal.rb.

jQuery(document).ready(function() {
  var table = $('#organizations-datatable');
  var token = $('meta[name=csrf-token]').attr('content');
  table.DataTable({
    "processing": true,
    "serverSide": true,
    "ajax": {
      "url": "/organizations/datatable.json",
      "type": 'POST',
      "beforeSend": function (xhr) {
          xhr.setRequestHeader('X-CSRF-Token', token)
        }
    },
    "pagingType": "full_numbers",
    "destroy": true,
    "columns": [
      {"data": "name"},
      {"data": "desc"},
      {"data": "industry"},
      {"data": "tags"}
    ],
    "iDisplayLength": 25
  });
});

Es beinhaltet auch das hinzufügen der CSRF-token, um die ajax-Anfrage für die Daten.

Ich möchte alle unsere javascript geschrieben werden als opal für die Lesbarkeit, etc. Bitte keine Debatte, dass die Wahl, ich habe nur darum zu verstehen, wie man diese arbeiten als Opalrb über opal/Schienen-ujs/opal-jquery

Die unten Opal erreicht nicht die gleiche wie die oben JS. Kann mir jemand helfen zu verstehen, warum?

Element.expose :DataTable

Document.ready? do
  token     = Element['meta[name=csrf-token]'].attr('content');
  settings  = {
      "processing": true,
      "serverSide": true,
      "ajax": {
        "url": "/organizations/datatable.json",
        "type": 'POST',
        "beforeSend": lambda do
          xhr = `new window.XMLHttpRequest()`
          xhr.setRequestHeader('X-CSRF-Token', token)
        end 
      },
      "pagingType": "full_numbers",
      "destroy": true,
    "columns": [
      {"data": "name"},
      {"data": "desc"},
      {"data": "industry"},
      {"data": "tags"}
    ]
    }
  Element['#organizations-datatable'].DataTable(settings.to_n)

end

Was vermisse ich hier? Warum ist dieser Opal gut?

Edit: Dies ist, was mein Weg aussieht, dieser sorgt für die POST arbeitet für diese:

Rails.application.routes.draw do
    concern :with_datatable do
        post 'datatable', on: :collection
    end
    resources :organizations,   concerns: [:with_datatable]
end

    Beginnen werde ich mit ausgestrecktem paar Fehler in Ihrem code ,

    1. Der code in beforeSend ist problematisch entnehmen Sie bitte den Liefer-und ein-xhr-Methodeändern Sie den code unten,

      "beforeSend": lambda do |xhr|

      `xhr.setRequestHeader('X-CSRF-Token', token)`

    schließen xhr Aussagen in ( ` ) backticks wie obige Aussage

    1. Spalten sollten zwei-dimensionales array anstatt array von Objekten,

      "columns": [ ["data": "name"], ["data": "desc"], ["data": "industry"], ["data": "tags"] ]

    Rest des Codes sieht gut aus.

    Unten ist der getestete code

    Element.expose :DataTable
    Document.ready? do
      token     = Element['meta[name=csrf-token]'].attr('content');
      settings  = {
          "ajax": {
            "url": "/data.json",
            "type": 'POST',
            "beforeSend": lambda do |xhr|
              `xhr.setRequestHeader('X-CSRF-Token', token)`
            end 
          },
          "pagingType": "full_numbers",
          "destroy": true,
        "columns": [
          ["data": "Name"],
          ["data": "Position"],
          ["data": "Office"],
          ["data": "Extn."],
          ["data": "Start"],
          ["data": "Salary"]
        ]
        }
      Element['#organizations-datatable'].DataTable(settings.to_n)
    
    end
    

    Stellen Sie sicher, Sie haben data.json - Datei im public-Ordner der rails-app, und die Inhalte wie folgt

    fügen Sie opal zu Gemfile,

    gem 'opal-rails'
    
    gem 'opal-jquery'
    

    application.js.rb Inhalt

    require 'opal'
    require 'jquery'
    require 'opal-jquery'
    require 'datatables.min'
    require_tree '.'
    

    fügen Sie datatables.min.js - Datei app/assets/javascripts Ordner

    html,

    <table id="organizations-datatable" class="display" style="width:100%">
        <thead>
            <tr>
                <th>Name</th>
                <th>Position</th>

        </tfoot>
    </table>
    

    HINWEIS :- Wenn Sie wollen, dass es funktioniert mit POST, die Sie zum anpassen Ihres config/routes.rb,

    Fügen Sie den folgenden Eintrag in der Routen.rb für Ihre json-Datei,

    Für mich war es,

    post '/data.json', :to => redirect('/data.json')
    

    Für Sie wird es sein,

    post '/organizations/datatable.json', :to => redirect('/organizations/datatable.json')
