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

Table of Content

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

`/tests` directory contains all unit test cases for this project:

/test_models/test_base_model.py - Contains the TestBaseModel and TestBaseModelDocs classes TestBaseModelDocs class:

def setUpClass(cls)- Set up for the doc tests

def test_pep8_conformance_base_model(self) - Test that models/base_model.py conforms to PEP8

def test_pep8_conformance_test_base_model(self) - Test that tests/test_models/test_base_model.py conforms to PEP8

def test_bm_module_docstring(self) - Test for the base_model.py module docstring

def test_bm_class_docstring(self) - Test for the BaseModel class docstring

def test_bm_func_docstrings(self) - Test for the presence of docstrings in BaseModel methods

TestBaseModel class:

def test_is_base_model(self) - Test that the instatiation of a BaseModel works

def test_created_at_instantiation(self) - Test created_at is a pub. instance attribute of type datetime

def test_updated_at_instantiation(self) - Test updated_at is a pub. instance attribute of type datetime

def test_diff_datetime_objs(self) - Test that two BaseModel instances have different datetime objects

/test_models/test_amenity.py - Contains the TestAmenityDocs class:
