How to let people download files on my website? – Apache

My site should scrape some data from another, everything worked on my computer. Once I put my app on a server and this error occurs. I changed permission to 777 for whole path folders and didn’t work. I’m using python3, apache 2.4 on ubuntu 18.10.

PermissionError at /scrape/ [Errno 13] Permission denied: FILENAME

    with open(local_filename, 'wb') as f:

    This change solved the problem.

    from django.conf import settings                    
with open(os.path.join(settings.MEDIA_ROOT, local_filename), 'wb') as f:

    It will throw error until it get the permission for the full path.
    Here is your directory structure string. 

    '/home/matms/django_project/media_root'

    Even if you have changed the permission for media_root folder but not of its parent directories i.e django_project, matms or home, it will throw error.

    Vice versa also works:
    If the application has permission to modify /home/matms/django_project/ but not media_root folder, it will again throw error.

    There are chances that you have changed only the permission of media_root. You have to change permissions of its parent directories too.
