Question

I’m currently storing all my photos on amazon s3 and using django for my website. I want a to have a button that allows users to click it and have all their photos zipped and returned to them.

I’m currently using boto to interface with amazon and found that I can go through the entire bucket list / use get_key to look for specific files and download them

After this I would need temporarily store them, then zip and return.

What is the best way to go about doing this?

Thanks

Answer 1

you can take a look at this question or at this snippet to download the file

# This is not a full working example, just a starting point
# for downloading images in different formats.

import subprocess
import Image

def image_as_png_pdf(request):
  output_format = request.GET.get('format')
  im = Image.open(path_to_image) # any Image object should work
  if output_format == 'png':
    response = HttpResponse(mimetype='image/png')
    response['Content-Disposition'] = 'attachment; filename=%s.png' % filename
    im.save(response, 'png') # will call response.write()
  else:
    # Temporary disk space, server process needs write access
    tmp_path = '/tmp/'
    # Full path to ImageMagick convert binary
    convert_bin = '/usr/bin/convert' 
    im.save(tmp_path+filename+'.png', 'png')
    response = HttpResponse(mimetype='application/pdf')
    response['Content-Disposition'] = 'attachment; filename=%s.pdf' % filename
    ret = subprocess.Popen([ convert_bin, 
                            "%s%s.png"%(tmp_path,filename), "pdf:-" ],
                            stdout=subprocess.PIPE)
    response.write(ret.stdout.read())
  return response

to create a zip follow the link that i gave you, you can also use zipimport as shown here examples are on the bottom of the page, follow the documentation for newer versions
