FastAPI example project for DB connections

In this repo, we have a FastAPI example project that

• you can develop with Docker and docker-compose
• connects to a PostgreSQL database with SQLModel and sqlalchemy with CRUD operations examples
• connects to Redis with CRUD operations examples
• connects to S3 with CRUD operations examples
• has basic unit tests
• has a simple CI pipeline yaml file for CircleCI

How to develop it?

Spin up docker-compose

$ docker-compose up -d --build

Now under localhost:8004/docs, you can find the APIs.

Tests

With

$ docker-compose exec web pytest .

you can run the tests and with something like

$ docker-compose exec web pytest tests/test_user.py

you can run specific tests, in this case for the rights endpoints of the API.

Use docker-compose logs web to check the logs of the FastAPI server.

To bring the docker containers down, simply run

$ docker-compose down -v

Push to Docker Hub

You can use something analogous to the following to push the image to Docker Hub:

docker build -f src/Dockerfile -t scraiber/fastapi-db-example:v1.0.0 .
docker push scraiber/fastapi-db-example:v1.0.0

Setup PyCharm virtual environment (for Python 3.12)

First, create a virtual environment for Python 3.12. Then run

python3.12 -m ensurepip --upgrade
python3.12 -m pip install --upgrade setuptools

in the terminal. After this, you can install the packages in requirements.txt.
