Simpl Games Framework API Project

This project requires PostgreSQL 9+ and uses Python 3.7.x and Django 2.2.x

Install simpl-games-api

$ git clone https://github.com/simplworld/simpl-games-api.git
$ cd simpl-games-api

Getting Started With Docker

Using docker is the easiest way to get started with Simpl. After you clone the repo, run:

$ docker-compose up

to get the Simpl API up and running on your local system.

After you have the containers up, you will need to create a superuser and staff user.

• The superuser is used to inspect the data in the Simpl API's Django admin .
• The staff user is used by Simpl model services to connect to the Simpl API.

In a separate terminal, create a shell into the Simpl API container by running:

$ make shell

make shell is just a helper that runs docker-compose run --rm api bash for you.

Once you are in the container shell, create your superuser and staff user by running:

$ ./manage.py simpl_setup

Create the staff user with email address simpl@simpl.world and password simpl.

Getting Started Without Docker

After you clone the repo, run:

$ mkvirtualenv simpl-games-api
$ pip install -r requirements.txt

Create PostgreSQL database

Create a database:

$ createdb simpl

Database Setup

Sync models to database:

$ ./manage.py migrate

Create a superuser for testing

Create a superuser account to access the admin:

$ ./manage.py createsuperuser

For local development, run:

$ ./manage.py create_simpl_user

This creates a super user with email address 'simpl@simpl.world' and password 'simpl' and ensures test users can be assigned passwords in scripts.

Settings setup

Setup the DJANGO_SETTINGS_MODULE to use:

$ export DJANGO_SETTINGS_MODULE=config.settings.local

Run the web server locally outside Docker:

$ ./manage.py runserver 0.0.0.0:8100

NOTE: You may need to create a directory named staticfiles and run manage.py collectstatic to have the admin media show up correctly.

Django's runserver does not support Keep-Alive requests, so we use gunicorn instead in production.

A command to run gunicorn is included in simpl-games-api:

$ ./manage.py run_gunicorn

Run tests

Run py.test:

$ export DJANGO_SETTINGS_MODULE=config.settings.test
$ py.test

Do not commit code if tests are failing.

Release

To release a new version of the docker image, tag a new version with bumpversion:

$ bumpversion patch

Then push to the repo:

$ git push && git push --tags

Generate updated ERD of Models

If you are using an environment that supports running Pillow, uncomment the Pillow line in requirements.txt and run:

$ pip install -r requirements.txt --upgrade
$ ./manage.py graph_models games -o docs/models.png

Model Schema

Check Deployed System

We have a simple management command which will check DNS, HTTP/HTTPS connectivity in general, ability to login to the admin, that the API responds properly and that the game slug in question is installed. To use this command you MUST have a valid admin login to use the command.

Simple usage:

manage.py check_deploy https://simpl.mine.ed/

The command will prompt you for your admin user's email address (aka username), password, and game slug. Or you can provide them on the command line like this:

manage.py check_deploy https://simpl.mine.ed/ --email='me@mine.ed' --password='sumpun' --game=sim

Count game model objects

Management command that print counts of all simpl model objects based on game slug. For example, run

./manage.py count_game_models -s calc

to see counts of all model objects for a game with slug 'calc'.
