PreSnax

Middleware between Engelsystem & Pretix for Angel Food Distribution

simple middleware supposed to sit between a pretix and a system like Engelsystem to provide volunteers with an option to get a food voucher.

This middleware is specifically designed to work with the C3 setup.

Pretix Setup:

• event series, each meal is one slot in the event series
• 3 different products (crew, regular & override)
• set quotas
• generate API key

Software Setup

• define meals
• define product types & the respective product id's
• define endpoint, api key, etc.
• define mail server
• generate auth token

Features

expects a json post request:

{
  "email": "foobar@example.org",
  "type": "regular",
  "meal": "tag4mittag"
}

authorized with a bearer token configurable in config.yaml

books the respective ticket (if available) and sends it to the specified email.

The ticket is booked with a dummy mail address (currently hardcoded)

if you book a ticket with %something%@printme.local it won't send an email but will answer with the secret code as response. This is implemented for the GUI that can override Engelsystem.

Currently configured types:

• regular (normal "engelsystem" bookings)
• crew (booking for users who have the crew flag in engelsystem)
• override (unlimited quota to override sold out meals)
