Deliverables

You are building an app for an Airbnb competitor

• your models are listings, guests, trips
  • a listing (i.e. a house or apartment) has many trips
    • a listing has a city attribute which is a string of a city name, e.g. 'Seattle'
  • a guest has many trips
  • a trip belongs to a listing and a guest
