Diese \u00c4nderung wirkt sich nur auf neu generierte Anwendungen aus, so dass es keine Probleme mit der R\u00fcckw\u00e4rtskompatibilit\u00e4t f\u00fcr Benutzer geben sollte, die ein Upgrade durchf\u00fchren, aber es kann einige Tutorials und Einf\u00fchrungsmaterial beeinflussen. Rails 3.2.3 f\u00fchrt auch eine neue Option ein, mit der Sie das Verhalten von Remote-Formularen steuern k\u00f6nnen, wenn es um <strong>echtheit_token<\/strong><span style=\"font-family: Liberation Serif,serif;\"> Erzeugung. Wenn Sie Ihre Formulare fragmentieren und cachen wollen, wird auch das Authentizit\u00e4ts-Token gecacht, was nicht akzeptabel ist. Wenn Sie solche Formulare jedoch nur mit Ajax verwenden, k\u00f6nnen Sie die Token-Generierung deaktivieren, da sie von <\/span><code>meta<\/code> Tag. Ab 3.2.3 haben Sie die M\u00f6glichkeit, die Erzeugung von <strong>echtheit_token<\/strong> in entfernten Formen (z.B.. <strong>:remote =&gt; true<\/strong> als Option \u00fcbergeben wird), durch Setzen von <strong>config.action_view.embed_authenticity_token_in_remote_forms = false<\/strong>. Bitte beachten Sie, dass das Senden von Formularen mit deaktiviertem Javascript dadurch unterbrochen wird. Wenn Sie sich daf\u00fcr entscheiden, das Token nicht standardm\u00e4\u00dfig in entfernten Formularen zu generieren, k\u00f6nnen Sie immer noch explizit <strong>:authenticity_token =&gt; true<\/strong> beim Erstellen des Formulars, um diese Einstellung zu umgehen. Die Option ist standardm\u00e4\u00dfig auf <code>wahr<\/code>was bedeutet, dass bestehende Anwendungen NICHT betroffen sind.\n\n1. Installieren Sie rails 3.2.3 gem\n<h4>gem install rails -v=3.2.3<\/h4>\n2. Um Javascript von mit in Ruby auszuwerten, m\u00fcssen Sie Folgendes installieren\n<h4>gem install therubyracer<\/h4>\n3. Installieren Sie die mysql2-Bibliothek f\u00fcr Ruby, um eine Verbindung zur Datenbank herzustellen und die Verbindung abzufragen\n<h4>gem install mysql2 -v=0.3<\/h4>\n4. Zum Ausf\u00fchren der Rake-Aufgabe installieren Sie das Gem\n<h4>gem install rake -v=0.9.2<\/h4>\n5. bcrypt-ruby ist ein hochentwickelter und sicherer Hash-Algorithmus, der vom OpenBSD-Projekt zum Hashing von Passw\u00f6rtern entwickelt wurde.\n<h4>gem install bcrypt-ruby -v=3.0.0<\/h4>\n6. ExecJS erm\u00f6glicht die Ausf\u00fchrung von JavaScript-Code in Ruby. Es w\u00e4hlt automatisch die beste verf\u00fcgbare Laufzeit, um Ihr JavaScript-Programm zu evaluieren, und gibt das Ergebnis dann als Ruby-Objekt zur\u00fcck.\n<h4>gem install execjs<\/h4>\n7. Die jquery-rails gem, die mit Rails als Standard-JavaScript-Bibliothek gem kommt. Dieses Gem enth\u00e4lt eine Engine-Klasse, die von Rails::Engine erbt. Dadurch wird Rails mitgeteilt, dass das Verzeichnis f\u00fcr dieses Gem Assets und die Verzeichnisse app\/assets, lib\/assets und vendor\/assets enthalten kann.\n<h4>gem install jquery-rails<\/h4>\n<h4><\/h4>\n8. Asset-Pipeline\n\nDie Asset-Pipeline bietet ein Framework zur Komprimierung von Javascript- und Css-Assets. Sie bietet auch die M\u00f6glichkeit, diese Assets in anderen Sprachen wie Coffeescript, Sass und ERB zu schreiben.\n\nIn fr\u00fcheren Versionen von Rails befanden sich alle Assets in Unterverzeichnissen von public wie Bilder, Javascripts und Stylesheets. Mit der Asset-Pipeline ist der bevorzugte Speicherort f\u00fcr diese Assets nun das app\/assets-Verzeichnis.\n\nWenn zum Beispiel ProjectsController generiert wird, f\u00fcgt Rails eine neue Datei unter\n\napp\/assets\/javascripts\/projects.js.coffee\n\napp\/assets\/stylesheets\/projects.css.scss.\n<h4><\/h4>\n<h3>Rails 3.2.3 Gemfile<\/h3>\ngem \"rails\", \"~&gt; 3.2.3\"\n\n# B\u00fcndeln Sie
