AirBnB Clone - The Console

The console is the first segment of the AirBnB project at Holberton School that will collectively cover fundamental concepts of higher level programming. The goal of AirBnB project is to eventually deploy our server a simple copy of the AirBnB Website(HBnB). A command interpreter is created in this segment to manage objects for the AirBnB(HBnB) website.

Functionalities of this command interpreter:

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

Environment

This project is interpreted/tested on Ubuntu 14.04 LTS using python3 (version 3.4.3)

Installation

Clone this repository: git clone "https://github.com/alexaorrico/AirBnB_clone.git"
Access AirBnb directory: cd AirBnB_clone
Run hbnb(interactively): ./console and enter command
Run hbnb(non-interactively): echo "<command>" | ./console.py

File Descriptions

console.py - the console contains the entry point of the command interpreter. List of commands this console current supports:

EOF - exits console
quit - exits console
<emptyline> - overwrites default emptyline method and does nothing
create - Creates a new instance ofBaseModel, saves it (to the JSON file) and prints the id
destroy - Deletes an instance based on the class name and id (save the change into the JSON file).
show - Prints the string representation of an instance based on the class name and id.
all - Prints all string representation of all instances based or not on the class name.
update - Updates an instance based on the class name and id by adding or updating attribute (save the change into the JSON file).

`models/` directory contains classes used for this project:

base_model.py - The BaseModel class from which future classes will be derived

def __init__(self, *args, **kwargs) - Initialization of the base model
def __str__(self) - String representation of the BaseModel class
def save(self) - Updates the attribute updated_at with the current datetime
def to_dict(self) - returns a dictionary containing all keys/values of the instance

Classes inherited from Base Model:

`/models/engine` directory contains File Storage class that handles JASON serialization and deserialization :

file_storage.py - serializes instances to a JSON file & deserializes back to instances

def all(self) - returns the dictionary __objects
def new(self, obj) - sets in __objects the obj with key .id
def save(self) - serializes __objects to the JSON file (path: __file_path)
def reload(self) - deserializes the JSON file to __objects
