This project forms part of the One Screenful of Python github organisation. For more information about that idea, see the README in the screenfuls repo:

https://github.com/OneScreenfulOfPython/screenfuls/blob/master/README.md

Build a booking system (ostensibly for rooms but could be for anything: gym equipment, library books etc.).

• Only use built-in modules (but suggest alternatives)

• Run unchanged on Python 2 and 3

• Run unchanged on any Python-supported platform (esp. including RPi)

• Keep core code simple, without using any more sophisticated Python idioms, but suggest alternatives / improvements.

• Remain import-table to allow for experimentation. This is especially useful as it makes it possible to experiment easily at the command line, eg:

  import bookings
  
  bookings.create_database()
  bookings.populate_database()
  print(bookings.get_user(1))
  print(bookings.get_room(1))
  bookings.add_booking_to_database(1, 1, '2014-11-18', '12:00')
  

• People have names & email addresses

• Rooms have names and locations

• Bookings are made by one person for one room on one day between Time A and Time B

• There should be a usable interface to book rooms / view room bookings

Steps -- each intended to be about a screenful. Each step leaves the application in a "working" state, albeit not necessarily a very interesting one, at least at first.

1. Create the empty database

2. Populate with some sample data: users, rooms, bookings

3. Create simple functions for accessing users & rooms

4. Create simple functions for accessing bookings via users & rooms

5. Refactor the database queries to use common functionality

6. Create a simple website with just a front page

7. Add /users to list users & /rooms to list rooms

8. Refactor the HTML pages to use common functionality

9. Add /bookings to list bookings for a user or a room

10. Add a user

11. Add a room

12. Add a booking (of a room by a user)

13. Add a booking (by a user of a room)

14. Show all bookings and allow additions

• You can use the sqlite ".dump" command to quickly see the database contents:

  sqlite bookings.db .dump
