ImproperlyConfigured: Requested setting INSTALLED_APPS, but settings are not configured - Scraper

问题

When I try to run my scraper in Django I get the following error.

This happened when I tried to put the scraped data into the database using the built-in Django models.

traceback and error:

/usr/bin/python3.6 /home/xxxxxx/Desktop/project/teo/movierater/scrap.py

django.core.exceptions.ImproperlyConfigured: Requested setting INSTALLED_APPS, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

I put it in bin/activate:

export DJANGO_SETTINGS_MODULE=mysite.settings

Here is the code snippet from scraper.py:

import django
import os
import requests
from bs4 import BeautifulSoup as bs
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
from teo.movierater.api.models import *


os.environ['DJANGO_SETTINGS_MODULE'] = 'movierater.settings'
django.setup()

When I try import models below django.setup():

import django
import os
import requests
from bs4 import BeautifulSoup as bs
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager

os.environ['DJANGO_SETTINGS_MODULE'] = 'movierater.settings'
django.setup()

from teo.movierater.api.models import *

Error:

ModuleNotFoundError: No module named 'movierater'

My project structure and the settings:

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'rest_framework',
    'movierater.api',
]

wsgi.py file:

import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'movierater.settings')

application = get_wsgi_application()

I can see a couple of possible issues here.

use movierater.settings as DJANGO_SETTINGS_MODULE value, i.e. export DJANGO_SETTINGS_MODULE=movierater.settings
- please note that movierater's location must be on your PYTHONPATH (ImproperlyConfigured: You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings)
how do you start your app, did you try python manage.py shell?
- ImproperlyConfigured: Requested setting INSTALLED_APPS, but settings are not configured
if you you want to start your scraper as a script (e.g. python manage.py scraper) then the best way to do it is to write a custom command; take a look at use django: from "python manage.py shell" to python script
