This is a project template which uses FastAPI, Alembic and async SQLModel as ORM. It shows a complete async CRUD using authentication and role base access control.

Async configuration for FastAPI and SQLModel

This is a project template which uses FastAPI, Alembic and async SQLModel as ORM. It shows a complete async CRUD template using authentication.

Set environment variables

Create an .env file on root folder and copy the content from .env.example. Feel free to change it according to your own configuration.

Run the project using Docker containers and forcing build containers

Using docker compose command

docker compose -f docker-compose-dev.yml up --build

Using Makefile command

make run-dev-build

Run project using Docker containers

Using docker compose command

docker compose -f docker-compose-dev.yml up

Using Makefile command

make run-dev

Setup database with initial data

This creates sample users on database.

Using docker compose command

docker compose -f docker-compose-dev.yml exec fastapi_server python app/initial_data.py

Using Makefile command

make init-db

Any of the above commands creates three users with the following passwords:

• Admin credentials -> username: [email protected] and password: admin
• Manager credentials -> username: [email protected] and password: admin
• User credentials -> username: [email protected] and password: admin

You can connect to the Database using pgAdmin4 and use the credentials from .env file. Database port on local machine has been configured to 5454 on docker-compose-dev.yml file

(Optional) If you prefer you can run pgAdmin4 on a docker container using the following commands, they should executed on different terminals:

Starts pgadmin

make run-pgadmin

Load server configuration (It is required just the first time)

make load-server-pgadmin

This starts pgamin in http://localhost:15432.

ERD Database model

Containers architecture

As this project uses traefik as a reverse proxy, which uses namespaces routing, you can access the documentation with the following path http://fastapi.localhost/docs

Preview

Traefik Dashboard

Traefik has been configurated as a reverse proxy on the ingress of the project; you can access Traefik Dashboard using the following link http://traefik.localhost/. You should use username: test and pass: test. If you want to change the password, you can find more information on how to do it here

Static files

All files on static folder will be served by nginx container as static files. You can check it with this link http://nginx.localhost/1.png

Minio server

This template allows users can upload their photos. The images are stored using the open source Object Storage Service (OSS) minio, which provides storage of images using buckets in a secure way through presigned URLs.

• Minio credentials -> username: minioadmin and password: minioadmin

Run Alembic migrations (Only if you change the DB model)

Using docker compose command

docker compose -f docker-compose-dev.yml exec fastapi_server alembic revision --autogenerate
docker compose -f docker-compose-dev.yml exec fastapi_server alembic upgrade head

Using Makefile command

make add-dev-migration

Production Deployment

Remember to use a persistant PostgreSQL database, update the new credentials on .env file and use this command to run the project in a production environment. For testing this configuration on localhost you can uncomment the database container and depends_on of fastapi container otherwise it will not work on a local environment.

Using docker compose command

docker compose up --build

Database unique IDs

Generating and using unique IDs is a really important desicion when starting a new project and its most common use is as primary keys for database tables. This project uses a custom UUID7 Draft04 implementation to make it simple to use and take advantage of UUID type of PostgreSQL. UUID7 combines timestamp with random data in order to help to convert data into time-stamped sequencially. If you are looking for another alternatives for tables IDs like Snowflakes, ULID, KSUID, pushID, xid among others you can check these references.

Code Style

To ensure a standardized code style this project uses black and flake8. If you want to change the config rules you can edit flake8 rules in the file setup.cfg or black in the file pyproject.toml.

To reformat files execute the following command

make formatter

To run lint, you can run the following command:

make lint
