1. cp .env.example .env
2. docker network create ffmemes_network
3. docker-compose up -d --build

Don't forget to fill the local .env file with all envs you need.

Before sending a PR you must test your new code. The easiest way is to run ipython shell, then import the functions you may need and test them. Note that ipython can run async functions without wrapping them with asyncio.run(...).

docker compose exec app ipython

Format the code with ruff --fix and ruff format

docker compose exec app format

• Create an automatic migration from changes in src/database.py

docker compose exec app makemigrations *migration_name*

• Run migrations

docker compose exec app migrate

• Downgrade migrations

docker compose exec app downgrade -1  # or -2 or base or hash of the migration

All tests are integrational and require DB connection.

One of the choices I've made is to use default database (postgres), separated from app's app database.

• Using default database makes it easier to run tests in CI/CD environments, since there is no need to setup additional databases
• Tests are run with upgrading & downgrading alembic migrations. It's not perfect, but works fine.

Run tests

docker compose exec app pytest

The template is using Just.

It's a Makefile alternative written in Rust with a nice syntax.

You can find all the shortcuts in justfile or run the following command to list them all:

just --list

We are using pg_dump and pg_restore to backup and restore the database.

• Backup

just backup
# output example
Backup process started.
Backup has been created and saved to /backups/backup-year-month-date-HHMMSS.dump.gz

• Copy the backup file or a directory with all backups to your local machine

just mount-docker-backup  # get all backups
just mount-docker-backup backup-year-month-date-HHMMSS.dump.gz  # get a specific backup

• Restore

just restore backup-year-month-date-HHMMSS.dump.gz
# output example
Dropping the database...
Creating a new database...
Applying the backup to the new database...
Backup applied successfully.
