Endpoint Tests

To test heroku environment. We have to export the variable otherwise pytest does not pick it up.

cd server && python server.py
export TEST_HEROKU='true' && pytest tests

To test the local app pytest tests

To make the server use Mongo as a server instead of the in-ram database invoke the server.py file with proper environment variables set.

cd server && USE_MONGO=1 MONGODB_URI=mongodb://127.0.0.1:27017/aang python server.py

cd ~/rajasthan
virtualenv -p python3 venv
source venv/bin/activate
pip install -r requirements.txt


# Mongo setup
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 2930ADAE8CAF5059EE73BB4B58712A2291FA4AD5
echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.6 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.6.list
sudo apt-get update
sudo apt-get install -y mongodb-org
sudo service mongod start
sudo service mongod enable

# nginx
sudo apt install nginx

To run the server then we can issue the following commands.

cd ~/rajasthan
source venv/bin/activate
cd server && USE_MONGO=1 MONGODB_URI=mongodb://127.0.0.1:27017/aang python server.py

In order to set up an nginx proxy we can use the following config in /etc/nginx/sites-available and then create a symlink for it in /etc/nginx/sites-enabled

server {
        client_max_body_size 1G;
	listen 80;

	location / {
		proxy_set_header X-Forward-For $proxy_add_x_forwarded_for;
		proxy_set_header Host $http_host;

		proxy_redirect off;
		if (!-f $request_filename) {
		    proxy_pass http://127.0.0.1:8000;
		    break;
		}
	}

}

The server is now available at http://<your machine's ip>

The data provided by DoIT&C can be uploaded by using the scripts present at this gist. Please note that the script does not upload MP4 and PNG. Those have to be manually uploaded in their respective categories.

NOTES

To avoid https strip attacks, all endpoints never send sensitive data to the client.
The server must be set up with https
The server's Admin page contains a brief tutorial of how to use the Admin page.
Admin setup requires inputs once. After that it works without prompt. On not receiving such input it prceeds with the defaults.
