import zipfile
from cStringIO import StringIO
from django.utils.httpwrappers import HttpResponse

def view_that_returns_zipped_file(request):
    response = HttpResponse(mimetype='application/zip')
    response['Content-Disposition'] = 'filename=all_things.zip'
    #first assemble your files
    files = []
    for thing in Thing.objects.all():
        files.append(("%s.pdf" % (thing.id,), thing.biggish_file()))
    #now add them to a zip file
    #note the zip only exist in memory as you add to it
    buffer = StringIO()
    zip = zipfile.ZipFile(buffer, "w", zipfile.ZIP_DEFLATED)
    for name, f in files:
        zip.writestr(name, f)
    zip.close()
    buffer.flush()
    #the import detail--we return the content of the buffer
    ret_zip = buffer.getvalue()
    buffer.close()
    response.write(ret_zip)
    return response
