rack-uploads

rack-uploads is a middleware which receives uploads and stores them in in the Rack env for easy access.

It works with normal HTTP file uploads, as well as with the Nginx Upload Module.

All multipart params get replaced by a Rack::Uploads::UploadedFile, while still retaining access to the original parameter value.

Dependencies

Development dependencies:

• rspec
• rack-test

Usage

Sinatra

  use Rack::Uploads

  post "/uploads" do
    env['rack.uploads'].each do |upload|
      upload.mv('/some/path/#{upload.filename}')
    end
  end

Rails

  # config/environment.rb
  config.middleware.use "Rack::Uploads"

  # app/controller/uploads_controller.rb
  class UploadsController < ApplicationController
    def create
      request['rack.uploads'].each do |upload|
        upload.mv("#{RAILS_ROOT}/public/uploads/#{upload.filename}")
      end
    end
  end

Options

There are a few options you can pass to rack-uploads during initializiation:

:session_authorized => lambda { |req| req.params[‘secret’] == "sekrit" } - Only allow uploads with the parameter "secret" set to "sekrit"

:nginx => [{ :tmp_path => "_tmp_path", :filename => "_file_name" }] - Sets the suffixes of the nginx upload parameters
