AirBnB clone - The console

Description

This team project is part of the Holberton School Full-Stack Software Engineer program. It's the first step towards building a first full web application: an AirBnB clone. This first step consists of a custom command-line interface for data management, and the base classes for the storage of this data.

Usage

The console works both in interactive mode and non-interactive mode, much like a Unix shell. It prints a prompt (hbnb) and waits for the user for input.

Command	Example
Run the console	./console.py
Quit the console	(hbnb) quit
Display the help for a command	(hbnb) help <command>
Create an object (prints its id)	(hbnb) create <class>
Show an object	(hbnb) show <class> <id> or (hbnb) <class>.show(<id>)
Destroy an object	(hbnb) destroy <class> <id> or (hbnb) <class>.destroy(<id>)
Show all objects, or all instances of a class	(hbnb) all or (hbnb) all <class>
Update an attribute of an object	(hbnb) update <class> <id> <attribute name> "<attribute value>" or (hbnb) <class>.update(<id>, <attribute name>, "<attribute value>")

Non-interactive mode example

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

Documented commands (type help <topic>):
========================================
EOF  all  count  create  destroy  help  quit  show  update

Models

The folder models contains all the classes used in this project.

File	Description	Attributes
base_model.py	BaseModel class for all the other classes	id, created_at, updated_at
user.py	User class for future user information	email, password, first_name, last_name
amenity.py	Amenity class for future amenity information	name
city.py	City class for future location information	state_id, name
state.py	State class for future location information	name
place.py	Place class for future accomodation information	city_id, user_id, name, description, number_rooms, number_bathrooms, max_guest, price_by_night, latitude, longitude, amenity_ids
review.py	Review class for future user/host review information	place_id, user_id, text

File storage

The folder engine manages the serialization and deserialization of all the data, following a JSON format.

A FileStorage class is defined in file_storage.py with methods to follow this flow: <object> -> to_dict() -> <dictionary> -> JSON dump -> <json string> -> FILE -> <json string> -> JSON load -> <dictionary> -> <object>

The init.py file contains the instantiation of the FileStorage class called storage, followed by a call to the method reload() on that instance. This allows the storage to be reloaded automatically at initialization, which recovers the serialized data.

Tests

All the code is tested with the unittest module. The test for the classes are in the test_models folder.
