Django TemporaryUploadedFile different behaviour under Python2/3 with delete=False

Why does the TemporaryUploadedFile get deleted in Python 3 while in Python 2 it stays in /tmp/ directory? And how would I keep the behavior of Python 2 while using 3?

from django.core.files.uploadedfile import TemporaryUploadedFile

with TemporaryUploadedFile('something.txt', 'text/plain', 0, 'UTF-8') as tmp_file:
    tmp_file_path = tmp_file.temporary_file_path()
    tmp_file.file.delete = False
    print(tmp_file_path)

Running this block of code under Python 2 keeps the file in /tmp/ directory while on Python 3 it gets deleted.

[ray@fedora tmp]$ ls | grep tmp
tmpvSmI8b.upload       #generated in Python 2

PY2 version 2.7.18
PY3 version 3.7.12
Django 1.11.29
Solution

  • Don't know the details of why this behavior is different but if you want to keep file in /tmp/ you need to instantiate NamedTemporaryFile with delete=False atrributes. Like this:

    NamedTemporaryFile(delete=False, ...)
