jQuery File Upload for Rails

jQuery-File-Plugin is a file upload plugin written by Sebastian Tschan. jQuery File Upload features multiple file selection, drag&drop support, progress bars and preview images for jQuery. Supports cross-domain, chunked and resumable file uploads and client-side image resizing.

jquery-fileupload-rails is a library that integrates jQuery File Upload for Rails 3.1 Asset Pipeline (Rails 3.2 supported).

Plugin versions

• jQuery File Upload Plugin v9.12.5

Installing Gem

gem "jquery-fileupload-rails"

Using the javascripts

Require jquery-fileupload in your app/assets/application.js file.

//= require jquery-fileupload

The snippet above will add the following js files to the manifest file.

//= require jquery-fileupload/vendor/jquery.ui.widget
//= require jquery-fileupload/vendor/tmpl
//= require jquery-fileupload/vendor/load-image.all.min
//= require jquery-fileupload/vendor/canvas-to-blob
//= require jquery-fileupload/jquery.iframe-transport
//= require jquery-fileupload/jquery.fileupload
//= require jquery-fileupload/jquery.fileupload-process
//= require jquery-fileupload/jquery.fileupload-image
//= require jquery-fileupload/jquery.fileupload-audio
//= require jquery-fileupload/jquery.fileupload-video
//= require jquery-fileupload/jquery.fileupload-validate
//= require jquery-fileupload/jquery.fileupload-ui
//= require jquery-fileupload/locale
//= require jquery-fileupload/jquery.fileupload-angular
//= require jquery-fileupload/jquery.fileupload-jquery-ui
//= require jquery-fileupload/cors/jquery.postmessage-transport
//= require jquery-fileupload/cors/jquery.xdr-transport

If you only need the basic files, just add the code below to your application.js file. Basic setup guide

//= require jquery-fileupload/basic

The basic setup only includes the following files:

//= require jquery-fileupload/vendor/jquery.ui.widget
//= require jquery-fileupload/jquery.iframe-transport
//= require jquery-fileupload/jquery.fileupload

You can also require the following to get the js from the Basic-Plus, AngularJS and jQuery UI Examples:

//= require jquery-fileupload/basic-plus

//= require jquery-fileupload/angularjs

//= require jquery-fileupload/jquery-ui

Using the stylesheet

Require the stylesheet file to app/assets/stylesheets/application.css

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

There are also noscript styles for Browsers with Javascript disabled, to use them create a noscript.css and add it to your precompile-list and layout inside a noscript tag:

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

Using the middleware

The jquery.iframe-transport fallback transport has some special caveats regarding the response data type, http status, and character encodings. jquery-fileupload-rails includes a middleware that handles these inconsistencies seamlessly. If you decide to use it, create an initializer that adds the middleware to your application's middleware stack.

Rails.application.config.middleware.use JQuery::FileUpload::Rails::Middleware
