IntelliJ IDEA not loading dependencies from docker compose - python django

I have set up a remote interpreter from the docker-compose option for a Django project. Still, it is showing me red squiggly lines under the package imports. How can I fix this?
docker-compose.yml
services:
app:
build:
context: .
args:
- DEV=true
ports:
- "8000:8000"
volumes:
- ./app:/app

sh -c "python manage.py wait_for_db &&
python manage.py migrate &&
python manage.py runserver 0.0.0.0:8000"
environment:
- DB_HOST=db
- DB_NAME=devdb
- DB_USER=devuser
- DB_PASS=changeme
depends_on:
- db
db:

Properly migrating Postgres database to Docker/Django/Heroku/Postgres

I have a Django project hosted on an IIS server with a Postgresql database that I am migrating to Docker/Heroku project. I have found a few good resources online, but no luck yet completely. I have tried to use the dumpdata/loaddata function but always run into constraint errors, missing relations, or content type errors. I would like to just dump the whole database and then restore the whole thing to Docker. Here is my docker-compose:
version: "3.7"
services:
db:
image: postgres
volumes:
- 'postgres:/var/lib/postgresql/data'
ports:
- "5432:5432"
environment:
- POSTGRES_NAME=${DATABASE_NAME}
- POSTGRES_USER=${DATABASE_USER}
- POSTGRES_PASSWORD=${DATABASE_PASSWORD}
- POSTGRES_DB=${DATABASE_NAME}
networks:
- hello-world
web:
build: .
command: python manage.py runserver 0.0.0.0:8000
volumes:
- '.:/code'
ports:
- "8000:8000"
env_file:
- .env
depends_on:
- db
networks:
- hello-world
networks:
hello-world:
driver: bridge
volumes:
postgres:
driver: local

I was actually able to resolve this I believe with the following command: "docker exec -i postgres pg_restore --verbose --clean --no-acl --no-owner -h localhost -U postgres -d < ./latest.dump"

Django app exited with code 252 on Docker

I am new to Docker, currently I am trying to deploy my app in a container. I have made 2 containers one for the DB and one for the app. But when I am trying to run my docker-compose file the app container exists with exit code 252. Here are the logs -
web_1 | Watching for file changes with StatReloader
web_1 | Performing system checks...
web_1 |
mushroomxpert_web_1 exited with code 252
This is my docker-compose file
version: '3.7'
services:
web:
image: mushroomxpert
build:
context: ./web
# command: 'gunicorn MushroomXpert.wsgi --log-file -'
command: python manage.py runserver 0.0.0.0:8000
ports:
- '8000:8000'
environment:
- ALLOWED_HOSTS=localhost
- DEBUF=False
- DB_NAME=mushroomxpert_db
- DB_USER=mushroom_admin
- DB_PASSWORD=chikchik1
- DB_HOST=db
- DB_PORT=5432
depends_on:
- db
db:
image: postgres
environment:
- POSTGRES_PASSWORD=chikchik1
- POSTGRES_USER=mushroom_admin
- POSTGRES_DB=mushroomxpert_db
EDIT 1- the problem seems to be occuring from Tensorflow, so I downgraded it's version to 2.2 after that the app worked. I am marking this as solved.

Please use something like this
version: "3.7"
db:
image: postgres
environment:
- POSTGRES_PASSWORD=chikchik1
- POSTGRES_USER=mushroom_admin
- POSTGRES_DB=mushroomxpert_db
expose:
- "5432"
web:
build:
context: ./web
dockerfile: YOUR DOCKERFILE
ports:
- "0.0.0.0:8000:8000"
volumes:
- "./backend/:/app/"
environment:
- ALLOWED_HOSTS: "localhost"
- DEBUG: "False"
- DB_NAME: "mushroomxpert_db"
- DB_USER: "mushroom_admin"
- DB_PASSWORD: "chikchik1"
- DB_HOST: "db"
- DB_PORT: "5432"
env_file:
- config.env
depends_on:
- db
command: >-
sh -c "
pip install -r requirements.txt &&
python manage.py runserver 0.0.0.0:8000
"
The above configuration contains everything that you need and moreover the connection between the db and your django application.

How one docker container can modify the file of another docker container?

My docker-compose file is as follows:
version: '3'
services:
db:
image: mongo:4.2
container_name: mongo-db
restart: always
environment:
MONGO_INITDB_DATABASE: VMcluster
ports:
- "16006:27017"
volumes:
- ./initdb.js:/docker-entrypoint-initdb.d/initdb.js
web:
build:
context: .
dockerfile: Dockerfile_Web
command: python manage.py runserver 0.0.0.0:8000
container_name: cluster-monitor-web
volumes:
- .:/vmCluster_service
ports:
- "9900:8000"
depends_on:
- db
cronjobs:
build:
context: .
dockerfile: Dockerfile_Cron
command: ["cron", "-f"]
container_name: cluster-monitor-cron
I want to implement a feature where the user should be able to update the crontab from the Django web. I'm done with Django part i.e python code for backend. But the Django web container is not able to access the crontab container.
how can I make Django web container to access the crontab container and update the crontab?
Im using python-crontab module in django which throws an error :
"[Errno 2] No such file or directory: '/usr/bin/crontab':
'/usr/bin/crontab'"

django docker-compose deleting data from mongo database when i am doing "docker-compose down" and again"up"

I have done setup django with mongodb inside docker using following docker-compose
command. it is working fine every thing. but when i am adding any records
using "docker exec -it 'img id' /bin/bash" it is inserting data(i tried creating superuser for django
admin panel). but, when i am again making it "docker-compose up" after "docker-compose down" it is
deleting all data from database showing empty records. so i am not able to access admin panel also for next timeself.
Please have a look.........

Add a volumes to
mongo:
image: mongo
ports:
- "27017:27017"
volumes:
- insert_mongos_stored_area
