Hi !

I’m attempting to write a simple gallery in Rails. The thing is I’d like  
to  
be able to upload a lot of pictures at once with a zip file.

I’ve so far managed to upload the zip file (containing pictures) to the  
server. But how do I unzip the file to have access to the pictures ? I  
haven’t been able to understand how to use Zlib to do this.

Any tips or ideas welcome, especially if you have a better way of  
accomplishing what I’d like to do…

Best regards,

David S.

[http://rubyzip.sourceforge.net/](http://rubyzip.sourceforge.net/)  
gem install rubyzip

Some example I found:

OUTDIR=“out”  
Zip::ZipFile::open(“all.zip”) { |zf|  
zf.each { |e|  
fpath = File.join(OUTDIR, e.name)  
FileUtils.mkdir\_p(File.dirname(fpath))  
zf.extract(e, fpath)  
}  
}

Software that uses rubyzip so you can look at examples are amongst
