Important! Need to update setup to include the changes that need to be made to required libraries

Setup
Celery
Database
Important notes on dependencies (If project isn't working)

SECTION 1: Setup

Install all of the requirements.

pip install -r requirements.txt

Install redis and rabbitmq. There are used by celery.

See section Important Notes on Dependencies if there are problems with setup

SECTION 2: Celery

Celery is used for periodic tasks. As of writing this (Jan 12th 2019) it is used for aborting all matches that went past their max_match_length. This is so players will have their money returned to them if an error occurs in a match and the game does not abort.

Start celery:

celery -A djangop worker --loglevel=info -P gevent

Start celery beat:

celery -A djangop beat -l info --scheduler django_celery_beat.schedulers:DatabaseScheduler

Celery also requires redis to be running, open ubuntu and run

service redis-server start

SECTION 3: Database

If the database has to be recreated and your getting a no such table error. Try the command:

python manage.py migrate --run-syncdb

Important Notes on Dependencies

Channel Layers

If there is an issue with channel layers remove the line importing Group. Replace all lines that use group with the new format:

# This example uses WebSocket consumer, which is synchronous, and so
# needs the async channel layer functions to be converted.
from asgiref.sync import async_to_sync
class ChatConsumer(WebsocketConsumer):
def connect(self):
    async_to_sync(self.channel_layer.group_add)("chat", self.channel_name)

def disconnect(self, close_code):
    async_to_sync(self.channel_layer.group_discard)("chat", self.channel_name)

Django Rest Framework

If there is an issue with djangorestframework... The version of djangorestframework doesn't work with this version of django. There should be a folder provided with the modified package rest_framework. If you cant find it just ask for it. This version should replace the one the environment.

Celery

If there is an issue with celery... There was a problem with celery before and I had modify it. Let me know if celery isn't working.

Channels Presence

There was also an issue with channels_presence. It didn't work with the current version of channels and I had to modify it.
