I have been reading how to write a django management command by reading this.
I did also read the django documentation but I am wondering if it's possible to write few commands to run using only one file?
instead of writing a few different files.

I don't think so. If I'm reading the source correctly commands are discovered from CLI by looking for modules:
https://github.com/django/django/blob/master/django/core/management/init.py#L26
Which collects using:
https://docs.python.org/2/library/pkgutil.html#pkgutil.iter_modules

Well I read the docs and it clearly states that it discovers commands from each of the module which defines a class Command. Agrees with dm completely.

Check this out - I think you can rework this to meet our needs. Really cool script. masnun.com/2015/09/29/…
You can write multiple commands in one file. Follow below steps
- Create management/init.py folder under your app root directory
- Under management directory create commands/init.py folder
- Create mycommand.py file under commands directory
- Write below codes in mycommand.py file
from django.core.management.base import BaseCommand
from subprocess import Popen
from sys import stdout, stdin, stderr
import time
import os
import signal
class Command(BaseCommand):
help = 'Run all commands'
commands = [
'python manage.py schedule',
'python manage.py runserver'
]
def handle(self, *args, **options):
proc_list = []
for command in self.commands:
print("$ " + command)
proc = Popen(command, shell=True, stdin=stdin,
stdout=stdout, stderr=stderr)
proc_list.append(proc)
try:
while True:
time.sleep(10)
except KeyboardInterrupt:
for proc in proc_list:
os.kill(proc.pid, signal.SIGKILL)- Change you cmd directory to yourProject root dir
- Run:
python manage.py mycommand
