Nutus - The Nuvola tus.io Resumable File Uploader

Here be a Rails Engine that is a minimal implementation of the tus.io Open Protocol for Resumable Uploads.

We're still not exactly sure what words are behind the TUS acronym, but we DO know that the protocol works.

This implementation is brought to you by the good folks at Nuvola Networks, who currently use tus.io in production.

Coming soon! (April 2016-ish)

• Documentation!
• Open source license!
• Publish to rubygems.org!
• Fame! Fortune! (Or maybe at least a "Kudos guys, that thing you did was alright." :))

Documentation

Add the following to your model

 class ModelName < ActiveRecord::Base
 ...
 attr_accessor :nutus_upload_url
 mount_uploader :assets, Uploader
 ...
 end

This gives the model somewhere to store the nutus url (just in ram)

In your form include this

 <div>
    <input type="file" onchange="app.uploader(this);">
    <%= f.hidden_field :nutus_upload_url %>
  </div>

Finally, in the controller (if using carrierwave) add this

 def update
 ...
 nutus_upload = Nutus::Upload.find i.nutus_upload_url.split(/\//).last
 nutus_upload_file = File.open nutus_upload.store_path
 vu = i.assets.nil? ? Uploader.new : i.assets
 vu.store! nutus_upload_file
 @model.cap_assets = vu
 @model.save
 ...
 end
