I am working on a home automation project, and I want to run certain python codes when going to certain URLs of my Django Webpage. The subprocess.call() line from my Django Views.py works perfectly on my Django development server:

from django.http import HttpResponse
import subprocess

def home():
    html = "<html><h1>Hello World</h1></html>" 
    return HttpResponse(html)

But the python script (or whatsoever command line) is not called on my Raspberry with Apache. According to many previous questions I've read, this could either be a SELinux issue or an premission issue (the Django/Apache user and group does not have permission to run commands).

Anyone can give me a hand on how to check whether this is caused by one or the other, and how to either configure SELinux or giving permission to Django/Apache to run commands?

    You might try printing the value of subprocess.call(...). It should return an error code; if 0, it ran fine (in theory), otherwise, an error occurred.

    Another possibility is that python is not on the path for the shell used by your Django/Apache process. Instead of python in the subprocess.call you might try specifying the full path to python on your machine.

What fixed if for me was replacing the standard Python executable with the path to the Python executable in the virtual environment, e.g. /var/www/mysite/venv/bin/python3 instead of python3
