Is it possible for rubyzip to return zipped data instead of writing it to the disk?

Hi,

I got simple Rails app and I'd like to compress xml data and send it
to the browser. I'm trying to use rubyzip for it, but i.e. the
following usage:

Zip::ZipFile.open("file.zip", Zip::ZipFile::CREATE) do |zip|
    zip.get_output_stream("file.xml") {|f| f.puts xml_data}
end

returns nil and creates file on the disk.

Is it possible for rubyzip to return zipped data (or file) instead of
writing it to the disk?

Write file to disk, give user link, delete file after a time, in case
the download has to be repeated.

Caching saves CPU and memory. :slight_smile:

Thanks.

I wanted to use Rails caching mechanisms (which I'm using i.e. to
cache generated XML datta to file). The result is the same - I got
zipped XML file on a disk - but by having raw data instead of a file
on a disk, I could have slightly cleaner code.

BTW. Is there some option to force rubyzip not to make temp files or
remove them after it's done? I can remove them manually, but it would
be easier :slight_smile:
