PayPark

PayPark is an open-source Automated Parking System written in Python.

Setup

Debian packaging will be the preferred way of deployment. Until that is setup pip and native Debian python packages can be used.

Dependencies

sudo apt-get install python-pip
sudo pip install -r requirements.txt

Configuration

Configuration is split into three different modes: Production, Testing, and Development. Edit paypark/config.py to change the database and other frontend/SMS settings.

@todo: Document configuration options and what they do

Running

Create and populate demo database:

python db.py --init --demo

Run the web application:

python app.py

Login to the web interface at http://localhost:8085:

Email: demo@demo.com
Password: demo

On another terminal, run the Twilio SMS API service:

python sms.py

The Twilio SMS API service is the default PayPark SMS service. You do not need a Twilio account to test and use the API service:

curl --form 'Body=start 1000' --form 'From=12345678901' --form 'MessagingServiceSid=' localhost:9000
{
    "error": "Missing: MessagingServiceSid"
}

Make sure you enter a value for MessagingServiceSid in the config file.

curl --form 'Body=start 1000' --form 'From=12345678901' --form 'MessagingServiceSid=12345' localhost:9000
{
    "error": "Phone number not registered."
}

In the web portal login as the demo user and add a phone number.

curl --form 'Body=start 1000' --form 'From=12345678901' --form 'MessagingServiceSid=12345' localhost:9000
<?xml version="1.0" encoding="UTF-8"?><Response><Message>Parking is free.</Message></Response>

SMS API Services

PayPark is configured to support different SMS API services to send and receive SMS messages:

• Twilio
• BulkSMS
