BACKEND

Docker stuff

The app is dockerised so we will be able to work on it without bigger problems with dependiences.

To spin up the app, type

$ docker-compose up

$ docker ps
CONTAINER ID   IMAGE                COMMAND                  CREATED          STATUS         PORTS                    NAMES
e2b5d78be02d   backend_app          "sh -c 'python manag…"   6 seconds ago    Up 4 seconds   0.0.0.0:8000->8000/tcp   backend_app_1
396aa851f220   postgres:13-alpine   "docker-entrypoint.s…"   32 minutes ago   Up 6 seconds   0.0.0.0:5432->5432/tcp   backend_db_1

now get inside the running container (e2b5d78be02d) by running docker exec -it e2b5d78be02d sh. You should be inside the running instance of the app.

Django management

Most of the stuff with django is done throught the command line by manage.py script.

• manage.py shell to go to the Django's shell
• manage.py makemigrations to perpare changes form models.py
• manage.py migrate to propagate the changes to the database

In the shell you can e.g. modify/add database content.

Django shell

from reservations.models import *
u = User(name="Tomas", surname="Dostal", is_admin=False)
u.save()
User.objects.all()
>> <QuerySet [<User: Dostal, Tomas>]>

Old good local development

pip install -r ./requirements.txt

if it fails, it might be needed to install openssl and run again.

brew install openssl
export LIBRARY_PATH=$LIBRARY_PATH:/usr/local/opt/openssl/lib/

To use dummy sqlite database change DATABASES in backend/settings.py to

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': BASE_DIR / 'db.sqlite3',
    }
}
