Hi, if an uploaded file exceeds the DATA_UPLOAD_MAX_MEMORY_SIZE of 2.5 mb,
django starts streaming the file data to a file in /tmp.
When finished it copies it over to the its required file path location,
but despite the permissions being set correctly, a permission denied
error occurs.
{{{
Request Method: POST

Exception Type: PermissionError
Exception Value:
[Errno 13] Permission denied:
'/opt/django_forum/django_forum/media/uploads/users/xxxxx

Python Version: 3.9.1
Python Path:

'/usr/local/lib/python3.9',
'/usr/local/lib/python3.9/lib-dynload',
'/usr/local/lib/python3.9/site-packages']
}}}
I have tried setting the following settings:
{{{
FILE_UPLOAD_DIRECTORY_PERMISSIONS = 0o755
FILE_UPLOAD_PERMISSIONS = 0o644
}}}
Most disturbingly, the files are created in their final position with 0755
permissions.
I am using a containerised workflow as opposed to a venv but I am not
certain that that should cause any issues.
