0x00. AirBnB clone - The console

Background Context Welcome to the AirBnB clone project! First step: Write a command interpreter to manage your AirBnB objects. This is the first step towards building your first full web application: the AirBnB clone. This first step is very important because you will use what you build during this project with all other following projects: HTML/CSS templating, database storage, API, front-end integration…

Each task is linked and will help you to:

put in place a parent class (called BaseModel) to take care of the initialization, serialization and deserialization of your future instances create a simple flow of serialization/deserialization: Instance <-> Dictionary <-> JSON string <-> file create all classes used for AirBnB (User, State, City, Place…) that inherit from BaseModel create the first abstracted storage engine of the project: File storage. create all unittests to validate all our classes and storage engine What’s a command interpreter? Do you remember the Shell? It’s exactly the same but limited to a specific use-case. In our case, we want to be able to manage the objects of our project:

Create a new object (ex: a new User or a new Place) - Retrieve an object from a file, a database etc… - Do operations on objects (count, compute stats, etc…) - Update attributes of an object - Destroy an object

Execution Your shell should work like this in interactive mode:

$ ./console.py (hbnb) help

EOF help quit

(hbnb) (hbnb) (hbnb) quit $ But also in non-interactive mode: (like the Shell project in C)

$ echo "help" | ./console.py (hbnb)

EOF help quit (hbnb) $ $ cat test_help help $ $ cat test_help | ./console.py (hbnb)

EOF help quit (hbnb) $ All tests should also pass in non-interactive mode: $ echo "python3 -m unittest discover tests" | bash by Edison and Marvin
