I''d like to add several separate files into a new Gzip file created
within ruby.
The code I''ve got at the moment is as follows:
File.open(''coursework_submissions.gz'', ''wb'')
do |f|
gz = Zlib::GzipWriter.new(f)
@student_list.each do |s|
temp = File.open("#{s.student.student_no}", ''wb'')
temp.write(s.submission)
temp.close()
gz.add(File.open("#{s.student.student_no}", ''r''))
File.delete("#{s.student.student_no}")
end
gz.close
end
However, this just produces a file, coursework_submissions.gz,
containing a file, coursework_submissions with the text of the files I
want to add contained inside. Where am I going wrong?
Thanks everyone.

Where am I going wrong?Gzip is not a container format. Usually one use TAR to pack multiple files/objects into one archive and than gzip it. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I don''t want to generate a .tar.gz file, but a .zip file that standard windows users can open (I''m an Ubuntu user but my client is not). How can I do that? -- Jaime Iniesta http://jaimeiniesta.com - http://railes.net - http://pagerankalert.com --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Google around for some examples on rubyzip. Although I personally would prefer the command line calls.
