Project in which the base of the AirBnB clone will be created as a study method.

All knowledge acquired in python will be implemented, its base structure will be:

• Create the basic classes where the most basic attributes will be saved, such as the time it was created and its respective ID.
• Create the basic methods that our interpreter will execute when we enter the commands corresponding to those methods.
• Verify each of the functions so that they execute with all possible cases to avoid errors. Each of these cases will be looked at later.

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

A command interpreter is the part of a computer operating system that understands and executes commands that are entered interactively by a human being or from a program. In some operating systems, the command interpreter is called the shell. 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

In this project we used Python 3.4 and was verified with pep8 1.7

We import this modules to create the console:

• import cmd
• import sys
• import json
• import subprocess

How to run a project?

You only need to run console.py file with this command ./console.py

This command must be executed in the root folder of the project like:

vagrant@vagrant-ubuntu-trusty-64:~/home/user/Documents/AirBnB_clone$ ./console.py

make sure all files are in the root directory.

First you need to run the console.py

Then you need to know the comands that the console can run:

• all: Prints all string representation of all instances based or not on the class name.

sintax: all <class name> or all

• create: Creates a new instance of BaseModel, saves it (to the JSON file) and prints the id.

sintax: create <class name>

• destroy: Deletes an instance based on the class name and id (save the change into the JSON file).

sintax: destroy <class name> <id>

• show: Prints the string representation of an instance based on the class name and id.

sintax: show <class name> <id>

• update: Updates an instance based on the class name and id by adding or updating attribute (save the change into the JSON file).

sintax: update <class name> <id> <attribute name> "<attribute value>" If you need more info type: (hbnb) ?or (hbnb) help.
