Code challenge

The objective of this code challenge is to develop a backend service or api.

I am developing an Api for CRUD operations over Restaurant objects.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. To get the server running you just need to run the docker-compose up command from the top level directory of the project.

docker-compose up

It is possible that the web container finishes loading up before the db container. In this case a message like the one below will appear.

web_1 | psycopg2.OperationalError: could not connect to server: Connection refused web_1 | Is the server running on host "db" (172.18.0.2) and accepting web_1 | TCP/IP connections on port 5432?

To fix this simply ctrl + c and docker-compose up again. Now the server should be running on localhost:8000.

Once the server is up and running make sure to run the migrations by doing:

docker-compose web run python3 manage.py migrate

The api is now available on localhost:8000/restaurants/. Check the documentation below for the detailed method description.
