Interested in incorporating the jquery fileupload rails?

Simply add this gem to your Gemfile: gem "jquery-fileupload-rails"

In the path app/assets/application.js, include //= require jquery-fileupload to add all necessary JS files.

For the CSS in app/assets/stylesheets/application.css, add:

*= require jquery.fileupload
*= require jquery.fileupload-ui

You can refer to the jQuery-File-Upload /wiki/ Basic-plugin for setup instructions or watch a tutorial on railscasts.com about jquery file upload

This sample code provides a basic upload form:

<!DOCTYPE HTML>
<html>
<head>
<meta charset="utf-8">
<title>jQuery File Upload Example</title>
</head>
<body>
<input id="fileupload" type="file" name="files[]" data-url="server/php/" multiple>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script src="js/vendor/jquery.ui.widget.js"></script>
<script src="js/jquery.iframe-transport.js"></script>
<script src="js/jquery.fileupload.js"></script>
<script>
$(function () {
    $('#fileupload').fileupload({
        dataType: 'json',
        done: function (e, data) {
            $.each(data.result.files, function (index, file) {
                $('<p/>').text(file.name).appendTo(document.body);
            });
        }
    });
});
</script>
</body> 
</html>

I trust this information proves beneficial.
