Reasoning

Why django

Django is a web framework in python. I chose it because of:

  1. Admin Interface (To provide CRUD operations)
  2. Testing Framework
  3. ORM
  4. Reusable django apps and packages

Frameworks and packages

  1. DRF - fast and convenient way to start your API

How to run:

docker-compose up
docker-compose exec app python manage.py migrate

Api

POST api/upload/ - import levels info from csv file
GET api/v1/levels/<id> - retrieve level info by id
GET api/v1/levels/?user_id=<user_id> - get list of levels, if called with user_id filters by user_id

Notes

Use Filters button to apply filters (sort, device timestamp, user_id)
For pagination use query params (limit, offset)

Trade-offs

  • I would use Celery to execute import task as a background process.
  • I would provide more in depth documentation about filters, pagination and sorts.
  • I would use permissions, auth, user model to provide secure access to endpoint.
  • I would set up fixtures to easier reuse objects across tests.
  • I would follow git flow to split project into features and name branches according to story purpose.
