Project Description

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

The goal of the project is to deploy a replica of the Airbnb Website using my server. The final version of this project will have:

1. A command interpreter to manipulate data without a visual interface, like a shell (for development and debugging)
2. A website (front-end) with static and dynamic functionalities
3. A comprehensive database to manage the backend functionalities
4. An API that provides a communication interface between the front and backend of the system.
5. General concepts in review

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

Documented commands (type help <topic>):
========================================
EOF  help  quit

(hbnb)
(hbnb)
(hbnb) quit
$

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

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

Documented commands (type help <topic>):
========================================
EOF  help  quit
(hbnb)
$
$ cat test_help
help
$
$ cat test_help | ./console.py
(hbnb)

Documented commands (type help <topic>):
========================================
EOF  help  quit
(hbnb)
$

All tests should also pass in non-interactive mode: $ echo "python3 -m unittest discover tests" | bash
