Streaming mp3 files in Django through Nginx

I have a website based on Django framework. I am running website via Nginx webserver (uWSGI,Django,Nginx). I want to stream mp3 files on my website with Accept-Ranges header. I want to serve my mp3 files with Nginx. I need my API to look like this

http://192.168.1.105/stream/rihanna


This must return mp3 file with partial download (Accept-Ranges).
My mp3 files are stored in : /home/docker/code/app/media/data/
When I run the server with these configurations and browse to 192.168.1.105/stream/rihanna , Django returns 404.

My Nginx conf:

# mysite_nginx.conf

# the upstream component nginx needs to connect to
upstream django {
server unix:/home/docker/code/app.sock; # for a file socket
# server 127.0.0.1:8001; # for a web port socket (we'll use this first)
}

# configuration of the server
server {
# the port your site will be served on, default_server indicates that this server block
# is the block to use if no blocks match the server_name
listen 80 default;
include /etc/nginx/mime.types;
# the domain name it will serve for
server_name .example.com; # substitute your machine's IP address or FQDN
charset utf-8;

# max upload size
client_max_body_size 75M; # adjust to taste

# Django media
location /media {
autoindex on;
sendfile on;
sendfile_max_chunk 1024m;
internal;
#add_header X-Static hit;
alias /home/docker/code/app/media/; # your Django project's media files - amend as required
}
location /static {
alias /home/docker/code/app/static/; # your Django project's static files - amend as required
}

# Finally, send all non-media requests to the Django server.
location / {

uwsgi_pass django;
include /home/docker/code/uwsgi_params; # the uwsgi_params file you installed
}
}


My views.py :

def stream(request, offset):
try:

mp3_path = os.getcwd() + '/media/data/' + offset + '.mp3'
mp3_data = open(mp3_path, "r").read()



except:
raise Http404()





response = HttpResponse(mp3_data, content_type="audio/mpeg", status=206)
response['X-Accel-Redirect'] = mp3_path
response['X-Accel-Buffering'] = 'no'
response['Content-Length'] = os.path.getsize(mp3_path)
response['Content-Dispostion'] = "attachment; filename=" + mp3_path
response['Accept-Ranges'] = 'bytes'


I want Nginx serve this files. And I really need Accept-Ranges enabled.

My Settings.py :

# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))


# Quick-start development settings - unsuitable for production

My problem is: It doesn't work, and Django return 404 Error webpage.

Answer

First of all, I did not copy the Nginx configuration file to the available-sites path. And because of it,It didn't work. And in my views.py :

response = HttpResponse(mp3_data, content_type="audio/mpeg", status=206)
response['X-Accel-Redirect'] = mp3_path

these 2 lines must be changed to:

response= HttpResponse('', content_type="audio/mpeg", status=206)
response['X-Accel-Redirect'] = '/media/data/' + offset + '.mp3'

I hope it helps anybody else who has this problem.
