How to fix the error cause when execute manage.py runserver command in Django?

Question

I recently join with ongoing project which has done using Django framework and I am new to this framework. This code is not mine. When I run python manage.py runserver command I receive following error.

I have done all the configuration asked in readme file.

This is the local.py file

try:
    from .base import *
except ImportError:
    pass

from configparser import RawConfigParser


config = RawConfigParser()
config.read('/etc/django_settings/hopster_settings.ini')

SECRET_KEY = config.get('secrets', 'SECRET_KEY')

This is the wsgi.py file

import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "hopster.settings.local")

application = get_wsgi_application()

This is the error

Did you fill the SECRET_KEY in the config file ? check this : stackoverflow.com/questions/7382149/… — O.O

dict.get() accepts an empty string as value, so config.get('secrets', 'SECRET_KEY') will not fallback to default if a key 'secrets' is found but empty — PRMoureu

I think the problem is in your manage.py. Your manage.py should be

import locale
import os
import sys

if __name__ == '__main__':
    locale.setlocale(locale.LC_ALL, '')
    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'hopster.settings.local')    # Your local.py

    try:
        from django.core.management import execute_from_command_line

    except ImportError as exc:
        raise ImportError(
            'Could not import Django. Are you sure it is installed and '
            'available on your PYTHONPATH environment variable? Did you '
            'forget to activate a virtual environment?'
        ) from exc

    execute_from_command_line(sys.argv)

Your manage.py file should be defined thus(as suitable for live deployment):

import os
import sys
import dotenv #pip install python3-dotenv

def main():
    """Run administrative tasks."""
    dotenv.load_dotenv(
        os.path.join(os.path.dirname(__file__), 'config.env')
    )

    os.environ.setdefault('DJANGO_SETTINGS_MODULE', "hopster.settings.local")

    if os.getenv("DJANGO_SETTINGS_MODULE"):
        os.environ["DJANGO_SETTINGS_MODULE"] = os.getenv("DJANGO_SETTINGS_MODULE")

    try:
        from django.core.management import execute_from_command_line
    except ImportError as exc:
        raise ImportError(
            "Couldn't import Django. Are you sure it's installed and "
            "available on your PYTHONPATH environment variable? Did you "
            "forget to activate a virtual environment?"
        ) from exc
    execute_from_command_line(sys.argv)


if __name__ == '__main__':
    main()

Then create a file (where your manage.py file is located) config.env and define the SECRET_KEY in that file. Furthermore, define the settings module. Your config.env file should looklike so:

DJANGO_SETTINGS_MODULE = hopster.settings.local
SECRET_KEY = tantallum@tungsten...(whatever)

In your settings.local file, define your SECRET_KEY as:

SECRET_KEY = os.getenv("SECRET_KEY")
