Unobtrusive File Upload adapter for jQuery UJS and Rails

This gem takes care about file uploads for remote form. It is a simple alternative for remotipart gem for rails. But instead of using iframe for file uploads this gem uses the base64 encoding to send the file to the server.

Installing

Add it to your Gemfile:

gem 'ufujs-rails'

Then run bundle install to update your application's bundle.

And in application.js under the jquery_ujs:

//= require jquery_ufujs

Usage

This gem encode the base64 string on the client side and handle the decoding in middleware, so we will get already decoded string in params on server side.

Data format

The string with the encoded data, should be prefixed with Data URI scheme format:

data:image/jpg;base64,(base64 encoded data)

Browser Compatibility

If you care about IE9 and lower, don't worry we are sure that you will have the white line in your life soon.

For IE9 and lower form will be submitted as HTML. You just have to add the authenticity_token option to your form

= form_for @record, remote: true, authenticity_token: true do
