#7651 closed (fixed)

Bug when uploading lists of files

Reported by: Julien Phalip Owned by: Michael Axiak
Component: HTTP handling Version: master
Severity: Keywords: upload, 2070-fix
Cc: Michael Axiak Triage Stage: Accepted
Has patch: yes Needs documentation: no
Needs tests: no Patch needs improvement: no
Easy pickings: no UI/UX: no



I'm using the jquery plugin MultiFile [1], which allows to dynamically create file fields in the form and then upload all the files when submitting the form.
It used to work totally fine before #2070 was merged. In my view I could do this:

file_dicts = []
for file_input_name in request.FILES:
    file_dicts += request.FILES.getlist(file_input_name)

However, since #2070's merge, the last file selected with MultiFile is duplicated.

uploaded_files = []
for file_input_name in request.FILES:
    uploaded_files += request.FILES.getlist(file_input_name)

uploaded_files returns:

list: [<TemporaryUploadedFile: test1.gif (image/gif)>, <TemporaryUploadedFile: test2.jpg (image/jpeg)>, <TemporaryUploadedFile: test2.jpg (image/jpeg)>]

The duplicate file to have an empty content. The problems happens both with TemporaryUploadedFile and InMemoryUploadedFile.

The MultiFile plugin is used by a lot of people on different platforms and with different web frameworks, and it used to work fine before #2070's merge, so to me this looks like a bug.

My first assumption is that the problem is in The code must enter the loop one time too much in the end somehow.
