How to startapp from inside docker-compose

Question

I have a problem in the steps of testdriven.io The definitive guide to Django Celery, when i want to start a new tdd app if i execute these commands `

$ docker-compose exec web bash

(container)$ ./manage.py startapp tdd

` it creates an app that is read only and pycharm cant change read only status. Some solutions say that it is because i created the app from root user but i cannot understand how to solve it. Here are the Dockerfile and the Docker-compose.

version: '3.3'

services:
  web:
    build:
      context: .
      dockerfile: ./compose/local/django/Dockerfile
    image: testdriven_web
    # '/start' is the shell script used to run the service
    command: /start
    # this volume is used to map the files and folders on the host to the container
    # so if we change code on the host, code in the docker container will also be changed
    volumes:
      - .:/app
    ports:
      - 8010:8000
    # env_file is used to manage the env variables of our project
    env_file:
      - ./.env/.dev-sample
    depends_on:
      - redis
      - db
  db:
    image: postgres:14-alpine
    volumes:
      - postgres_data:/var/lib/postgresql/data/
    environment:
      - POSTGRES_DB=hello_django
      - POSTGRES_USER=hello_django
      - POSTGRES_PASSWORD=hello_django

  redis:
    image: redis:7-alpine

  celery_worker:
    build:
      context: .
      dockerfile: ./compose/local/django/Dockerfile
    image: testdriven_celery_worker
    command: /start-celeryworker
    volumes:
      - .:/app
    env_file:
      - ./.env/.dev-sample
    depends_on:
      - redis
      - db

  celery_beat:
    build:
      context: .
      dockerfile: ./compose/local/django/Dockerfile
    image: testdriven_celery_beat
    command: /start-celerybeat
    volumes:
      - .:/app
    env_file:
      - ./.env/.dev-sample
    depends_on:
      - redis
      - db

  flower:
    build:
      context: .
      dockerfile: ./compose/local/django/Dockerfile
    image: testdriven_celery_flower
    command: /start-flower
    volumes:
      - .:/app
    env_file:
      - ./.env/.dev-sample
    ports:
      - 5557:5555
    depends_on:
      - redis
      - db

volumes:
  postgres_data:

And the Dockerfile `

I tried creating a user in the dockerfile using this as a base but i was unsuccessful https://github.com/testdrivenio/django-on-docker/issues/10
