Install pipenv if you don't have it yet:

pip install pipenv

Install the dependencies (you need Python 3.9):

pipenv install

Activate virtual env:

pipenv shell

Set the database to local:

export DATABASE_URL="sqlite:///db/db.sqlite3"

Make migrations:

make migrations
# python manage.py migrate

Add an admin user:

make admin
# python manage.py createsuperuser

Add some data:

make data

make run
# python manage.py runserver 0.0.0.0:8000

Build it:

docker build -t course_management .

Run it:

docker run -d \
    -p 8000:8000 \
    --name course_management \
    -e DATABASE_URL="sqlite:////data/db.sqlite3" \
    -v ${PWD}/db:/data \
    course_management

if you're on cygwin:

docker run -it --rm \
    -p 8000:8000 \
    --name course_management \
    -e DATABASE_URL="sqlite:////data/db.sqlite3" \
    -v `cygpath -w ${PWD}/db`:/data \
    course_management

remove the container later

docker rm course_management

get to the container

docker exec -it course_management bash

If you want to authenticate with OAuth locally (not requeired for testing), do the following

• Go to the admin panel (http://localhost:8000/admin)
• Add a record to "Sites"
  • "localhost:8000" for display and domain names
  • note the ID of the site (probably it's "2")
• Add records to "Social applications":
  • GoogleDTC. Provider: Google
  • Ask Alexey for the keys. Don't share them publicly
  • For the site, choose the localhost one

Export SITE_ID (should be the ID of the localhost site):

export SITE_ID=2

Restart the app:

python manage.py runserver 0.0.0.0:8000

Now log out as admin and log in with Google

Prep work

Host bastion-tunnel
    HostName <IP>
    User ubuntu
    IdentityFile c:/Users/alexe/.ssh/<KEY>.pem
    LocalForward 5433 dev-course-management-cluster.cluster-cpj5uw8ck6vb.eu-west-1.rds.amazonaws.com:5432
    ServerAliveInterval 60

Connect to the bastion

ssh bastion-tunnel

And then

pgcli -h localhost -p 5433 -u pgusr -d coursemanagement

When connecting for the first time, create dev and prod schemas

CREATE DATABASE dev;
CREATE DATABASE prod;

Django shell

export DATABASE_URL="postgresql://pgusr:${DB_PASSWORD}@localhost:5433/dev"
export SECRET_KEY="${DJANGO_SECRET}"

pipenv run python manage.py shell

or

export DATABASE_URL="postgresql://pgusr:${DB_PASSWORD}@localhost:5433/prod"
export SECRET_KEY="${DJANGO_SECRET}"

Finding user with email:

from django.contrib.auth import get_user_model
User = get_user_model()

user = User.objects.get(email='[email protected]')

There are /data endpoints for getting the data

Using them:

TOKEN="TOKEN"
HOST="http://localhost:8000"
COURSE="fake-course"
HOMEWORK="hw1"

curl \
    -H "Authorization: ${TOKEN}" \
    "${HOST}/data/${COURSE}/homework/${HOMEWORK}"
