My error is:

IOError at /mytest/photo/upload/

[Errno 2] No such file or directory: u'/mytest/photo/upload/2.png'

And my view is:

UPLOAD_URL = '/mytest/photo/upload/'

def upload(request):
    buf = request.FILES.get('photo', None)
    print buf
    if buf:
        #data = buf.read()
        #f = StringIO.StringIO(data)
        image = Image.open(buf)
        #image = image.convert('RGB')
        name = '%s%s' % (UPLOAD_URL, buf.name)
        image.save(file(name, 'wb'), 'PNG')
        return HttpResponse('ok')
    return HttpResponse('no')

And my urls.py is:

urlpatterns = patterns('mytest.views',
    url(r'^photo/upload/$','upload',name="")
)

How can I fix this?
