I know there is a docs about how to serve media files but I can't understand it enough, forgive me, especially the 'to' part, because english is not my native
If you're using Django's default uploaded files handling, then you'll need to set up a similar static files mapping from MEDIA_URL to MEDIA_ROOT...
and because the description in the static files section says
Files that aren't dynamically generated by your web app, like CSS files and JavaScript, can be served much faster straight off the disk if you specify them here. You need to Reload your web app to activate any changes to your static files.
I immediately assume that that section is not meant for media files.
Thanks for telling me what is already in the docs I guess >:-(
