[closed] Django, json uploads and nginx buffering

Here's a partial of a view that processes an uploaded json file.

def add_tag_data(f):

with open(settings.JSON_UPLOAD_DIRECTORY + f.name, 'wb+') as destination:
    for chunk in f.chunks():
        destination.write(chunk)

with open(settings.JSON_UPLOAD_DIRECTORY + f.name) as json_data:
    album_db = json.load(json_data)

I just mimicked the behavior I used for testing on my own machine and wrote the file to a directory I specified in settings.

On WebFaction Nginx comes in to play. I'm getting an error from the Django process:

[Errno 2] No such file or directory: '/home/danjewett/webapps/findcoltrane/tmp/O.json' as if the file is not being written to disk, and I'm getting a warning from Nginx:

2017/12/06 22:08:30 [warn] 35884#0: *45632687 a client request body is buffered to a temporary file /var/cache/nginx/client_temp/0000007895, client: 67.85.216.93,...

I'm not sure if buffering is the issue, or whether I'm just coding it incorrectly. The process fails with files of any size. The smallest I tried was @100KB

My code is trying to write the file to one location while Nginx has another idea?.
