Fairly recently Django changed the way that POST data was parsed — at least when multipart POST data is submitted (required for file uploads). PyISAPIe needs a small tweak in order for it to work with the new API.
The change that is needed is in
django.core.handlers.pyisapie.PyISAPIeRequest._load_post_and_files(). It should read:
def _load_post_and_files(This): "Populates This._post and This._files" Ctype = Env.HTTP_CONTENT_TYPE or '' if Ctype.startswith('multipart'): import StringIO This._post , This._files = http.HttpRequest.parse_file_upload(This, This.META, StringIO.StringIO(This.raw_post_data)) else: This._post, This._files = http.QueryDict(This.raw_post_data), datastructures.MultiValueDict()
Rather surprisingly this took me about 4 hours to write, partly due to a load of incorrect comments in
django.http.multipartparser.py about which I'm going to post a ticket and a patch (which hopefully might make it in before release).
