codenames

This project was generated using fastapi_template.

Poetry

This project uses poetry. It's a modern dependency management tool.

To run the project use this set of commands:

poetry install
poetry run python -m codenames

This will start the server on the configured host.

You can find swagger documentation at /api/docs.

You can read more about poetry here: https://python-poetry.org/

Docker

You can start the project with docker using this command:

docker-compose -f deploy/docker-compose.yml --project-directory . up --build

If you want to develop in docker with autoreload add -f deploy/docker-compose.dev.yml to your docker command. Like this:

docker-compose -f deploy/docker-compose.yml -f deploy/docker-compose.dev.yml --project-directory . up

This command exposes the web application on port 8000, mounts current directory and enables autoreload.

But you have to rebuild image every time you modify poetry.lock or pyproject.toml with this command:

docker-compose -f deploy/docker-compose.yml --project-directory . build

Configuration

This application can be configured with environment variables.

You can create .env file in the root directory and place all environment variables here.

All environment variabels should start with "CODENAMES_" prefix.

For example if you see in your "codenames/settings.py" a variable named like random_parameter, you should provide the "CODENAMES_RANDOM_PARAMETER" variable to configure the value. This behaviour can be changed by overriding env_prefix property in codenames.settings.Settings.Config.

An exmaple of .env file:

CODENAMES_RELOAD="True"
CODENAMES_PORT="8000"
CODENAMES_ENVIRONMENT="dev"

You can read more about BaseSettings class here: https://pydantic-docs.helpmanual.io/usage/settings/

Pre-commit

To install pre-commit simply run inside the shell:

pre-commit install

pre-commit is very useful to check your code before publishing it. It's configured using .pre-commit-config.yaml file.

By default it runs:

• black (formats your code);
• mypy (validates types);
• isort (sorts imports in all files);
• flake8 (spots possibe bugs);
• yesqa (removes useless # noqa comments).

Migrations

If you want to migrate your database, you should run following commands:

# To run all migrations untill the migration with revision_id.
alembic upgrade "<revision_id>"

# To perform all pending migrations.
alembic upgrade "head"

Reverting migrations

If you want to revert migrations, you should run:

# revert all migrations up to: revision_id.
alembic downgrade <revision_id>

# Revert everything.
 alembic downgrade base

Migration generation

To generate migrations you should run:

# For automatic change detection.
alembic revision --autogenerate

# For empty file generation.
alembic revision

Running tests

If you want to run it in docker, simply run:

docker-compose -f deploy/docker-compose.yml --project-directory . run --rm api pytest -vv .
docker-compose -f deploy/docker-compose.yml --project-directory . down

For running tests on your local machine.

2. Run the pytest.

pytest -vv .
