Question

Ruby 1.9.3 Rails 3.2.11. I need to require the ails zip library but can’t figure out how to do it. Here is my code which I need only in a single action in a controller.

  file_name = "natfiles.zip"
  t = Tempfile.new("temp_natfiles")
  Zip::ZipOutputStream.open(t.path) do |z|

      z.put_next_entry('NAT00010')
      z.print IO.read("tmp/nat00010")

  end
  send_file t.path, :type => 'application/zip',
                         :disposition => 'attachment',
                         :filename => file_name
  t.close

Answer 1

In your Gemfile, add a line

gem "rubyzip", :require => 'zip/zip'

Then run bundle install. It will be available everywhere.
