Im developing a django erp application and want to run it without stop. If we do runserver from a terminal it may be stopped at a point of time automatically. So what i seek for is to tell the os to run django as it boot up. Can subprocess of python a good idea to call from cron at startup ?

Is there a way to start a python script in the terminal every time I start a specific application?
I need a script to be running in the background to work with a software, but if I forget to start it before I launch the app, I have to shut down everything, start the script and reopen the app.
I tried in automator, but I couldn't find a trigger for when app is launched.
I want to know if there's a way to have windows server 2019 automatically launch django's web server. I also want the launch to be performed at startup and by SYSTEM.
I tried using batch scripts that launch manage.py from venv's python interpreter. When I launch the batch manually (i.e. double click) it works fine and dandy. But it appears that SYSTEM fails in running the script correctly when planning the task.
I made SYSTEM launch another script at startup (a simple python script that creates a txt file from within its own venv) and it works.
If the Django launch sceipt is launched by USER then it works.
The problem is with the launching of django with SYSTEM. I've also tried streamlit and the result is the same.
Do you have any Ideas?
Sample batch script:
cd path\of\managepyfile\
C:\path_to_venv\Scripts\python -m manage.py runserver
We run a similar application (not python) but an application that uses a web server.
We have it setup as a task in task scheduler that when the server starts up, it runs the powershell script that executes a command to start the web server.

However, you could use a web server like IIS and deploy the files to the www folder in the cdrive and run the site as an IIS service.
Setting it up on IIS was a little tricky if you've never used IIS before. Happy to help out as we have deployed our test access tool for one of our apps this way.
coming from Linux I have to build a Django application on Windows Server.
Everything works fine, but I have a Django command that needs to be run every hour.
In Linux I would create a cronjob.
I wrote a batch file that activates the virtual env and runs the django command, scheduled it with windows, but the command jobs fails, despite task scheduler says it executed properly.
What is simple on Linux on Windows it seems to be rocket science...
I feel that task scheduler / batch file approach isn't the right way to do that.
Is there a more pythonesque way to run a django command on windows server every hour?
thanx in advance,
Jan
coming back late, but I solved it with a django custom command:

I have coded a Python Script for Twitter Automation using Tweepy. Now, when i run on my own Linux Machine as python file.py The file runs successfully and it keeps on running because i have specified repeated Tasks inside the Script and I also don't want to stop the script either. But as it is on my Local Machine, the script might get stopped when my Internet Connection is off or at Night. So i couldn't keep running the Script Whole day on my PC..
So is there any way or website or Method where i could deploy my Script and make it Execute forever there ? I have heard about CRON JOBS before in Cpanel which can Help repeated Tasks but here in my case i want to keep running my Script on the Machine till i don't close the script .
Are their any such solutions. Because most of twitter bots i see are running forever, meaning their Script is getting executed somewhere 24x7 . This is what i want to know, How is that Task possible?
As mentioned by Jon and Vincent, it's better to run the code from a cloud service. But either way, I think what you're looking for is what to put into the terminal to run the code even after you close the terminal. This is what worked for me:
nohup python code.py &
You can add a systemd .service file, which can have the added benefit of:
logging (compressed logs at a central place, or over network to a log server)
disallowing access to /tmp and /home-directories
restarting the service if it fails
starting the service at boot
setting capabilities (ref setcap/getcap), disallowing file access if the process only needs network access, for instance
The idea:
There is a Node.JS server which sends a request to the IIS server which is running Django / Python. It will send two files to the server which need to be converted with a program which needs to be run in the foreground mode.
So I already looked around in pretty much everything related to IIS and the running of executables here on SO, but still haven't got it working.
I got the following code to run the application from Django:
subprocess.call("C:\example.exe")
There will be probably be some serious security issues (although the server is only reachable from the local network) with the following setup, but here it is:
I'm running a Django application on IIS.
I've set the Application Pool Identity to my local user
I've given "Full Control" permission to "Everyone"
When the subprocess call gets executed it will add the program to my Background Processes with the USER being set to my local user.
Questions:
How do I make the program start in Desktop Mode?
Should I perhaps add another step (start another service) which will then start the program?
Edit:
Could I perhaps make a file watcher which watches if files get stored on the Windows Server and then triggers an executable based on that?
