Rack-offline issue in rails 4 with more details

Rails
1

Recently i have posted this issue, so then i tried another way to cache
the
javascript and css, things like

This is routes.rb

offline = Rack::Offline.configure do

cache ActionController::Base.helpers.asset_path(“application.css”)
cache ActionController::Base.helpers.asset_path(“application.js”)
cache ActionController::Base.helpers.asset_path(“jquery.offline.js”)
cache ActionController::Base.helpers.asset_path(“jquery.tmpl.min.js”)
cache ActionController::Base.helpers.asset_path(“json.js”)

network "/"end
get “/application.manifest” => offline

This is the application.html.erb

<html

manifest="/application.manifest">OfflineTest<%=
stylesheet_link_tag ‘application’, media: ‘all’ %><%=
javascript_include_tag ‘application’ %><%= csrf_meta_tags
%>
<%= yield %>

This is index.html.erb

Listing
<%= form_for Item.new do |f| %>

<%= f.text_field :name %><%= f.submit
“Add” %>

<% end %> <ol

id=“items”>

  • Loading items…

    • This is application.js

    //= require jquery//= require jquery_ujs//= require jquery.tmpl.min//=
    require jquery.offline//= require json//= require_tree .

    $(document).ready(function(){if ($.support.localStorage) {
    $(window.applicationCache).bind(“error”, function() {
    console.log(“There was an error when loading the cache
    manifest.”);});if (!localStorage[“pendingItems”]) {
    localStorage[“pendingItems”] = JSON.stringify([]);}
    $.retrieveJSON("/items.json", function(data) {
    var pendingItems = $.parseJSON(localStorage[“pendingItems”]);
    $("#items").html($("#item_template").tmpl(data.concat(pendingItems)));});
    } else {
    alert(“Try a different browser.”);}});

    and added the gem

    gem “rack-offline”

    after this when i go for the application.manifest , it seems like

    CACHE MANIFEST#

    NETWORK: /

    So the problem coming here like, when i stop the server and check, its
    not
    loading the JS and CSS files, that means not loading the data in view,
    but
    its working with online, actually i have tried the same way in rails
    4.0.2
    and ruby 2.0.0 that worked. but when i comes to rails 4.1.6 and ruby
    2.1.2
    its not working with the offline mode. is there any issues with my
    configuration and all these?
