ViewsHow to return Django project's error messages when I use nginx in production mode
I have developed the Django project and deployed it to the Amazon's free tier EC2 services. Everything is fine except errors message that are not returning back. I am using the project in production mode.
Explanation for above image [Console Log]:
Successful request and response - it was made for existing url
Second request is made intentionaly to non existing url and did not receive any response.
I want to get at least 404 response, the problem I have is not having any response from server. When I run it on server I saw it is logging the results to the server.
Question:
How to return the response that Django is generating when something is wrong.
Extra Info: Those error messages and response are getting generated in djangorestframework's built in template.
Extra Details:
Let me know if I am missing anything.

Brain does really interesting things when it is tired. Thanks to @iklinac. He was right, better I would have used django-cors-headers correctly. It was already installed and working on heroku, when I moved to amazon aws I thought anything was related to NGINX.
Notes to take.
pip install django-cors-headers
Make sure it is in your installed apps.
INSTALLED_APPS = [
...
'corsheaders',
...
]
- You will also need to add a middleware class to listen in on responses: # which I have missed
MIDDLEWARE = [ # Or MIDDLEWARE_CLASSES on Django < 1.10
...
'corsheaders.middleware.CorsMiddleware',
'django.middleware.common.CommonMiddleware',
...
]
- A list of origins that are authorized to make cross-site HTTP requests
CORS_ORIGIN_WHITELIST = [
"https://example.com",
"https://sub.example.com",
"http://localhost:8080",
"http://127.0.0.1:9000"
]
Then there are few other things you can tweak and use as you want.
Eventually I have changed my nginx.conf to following
upstream hello_django {
server web:8000;
}
server {
listen 80;
location / {
proxy_pass http://hello_django;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_redirect off;
}
location /staticfiles/ {
alias /home/app/web/staticfiles/;
}
location /mediafiles/ {
alias /home/app/web/mediafiles/;
}
}
Happy coding.) credits to testdriven.io and django-cors-headers

You are proxy passing requests and they don't get add_header correctly, you should proxy pass after you add headers
location / {
add_header 'Access-Control-Allow-Origin' '*';
add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS, PATCH, PUT, DELETE';
add_header 'Access-Control-Allow-Credentials' 'true';
add_header 'Access-Control-Allow-Headers' 'Authorization,Accept,Origin,DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Content-Range,Range';
if ($request_method = 'OPTIONS') {
add_header 'Access-Control-Allow-Origin' '*';
add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS, PATCH, PUT, DELETE';
#
# Custom headers and headers various browsers *should* be OK with but aren't
#
add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range, Authorization';
#
# Tell client that this pre-flight info is valid for 20 days
#
add_header 'Access-Control-Max-Age' 1728000;
add_header 'Content-Type' 'text/plain; charset=utf-8';
add_header 'Content-Length' 0;
return 204;
}
proxy_pass http://app;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_redirect off;
Other way around would be to add django-cors-headers into your application
