AirBnB clone - MySQL

This repository contains the initial stage of a student project to build a clone of the AirBnB website. This stage implements a backend interface, or console and database, to manage program data. Console commands allow the user to create, update, and destroy objects, as well as manage file storage and data base storage. Using a system of JSON serialization/deserialization and MySQL, storage is persistent between sessions.

Learning Objectives

• What is Unit testing and how to implement it in a large project
• What is *args and how to use it
• What is **kwargs and how to use it
• How to handle named arguments in a function
• How to create a MySQL database
• How to create a MySQL user and grant it privileges
• What ORM means
• How to map a Python Class to a MySQL table
• How to handle 2 different storage engines with the same codebase
• How to use environment variables

General Use

1. First clone this repository.

2. Once the repository is cloned locate the "console.py" file and run it as follows:

/AirBnB_clone_v2$ ./console.py

4. When this command is run the following prompt should appear:

(hbnb)

5. This prompt designates you are in the "HBnB" console. There are a variety of commands available within the console program.

Commands

* create - Creates an instance based on given class

* destroy - Destroys an object based on class and UUID

* show - Shows an object based on class and UUID

* all - Shows all objects the program has access to, or all objects of a given class

* update - Updates existing attributes an object based on class name and UUID

* quit - Exits the program (EOF will as well)

Alternative Syntax

Users are able to issue a number of console command using an alternative syntax:

Usage: <class_name>.<command>([<id>[name_arg value_arg]|[kwargs]])

Advanced syntax is implemented for the following commands:

* all - Shows all objects the program has access to, or all objects of a given class

* count - Return number of object instances by class

* show - Shows an object based on class and UUID

* destroy - Destroys an object based on class and UUID

* update - Updates existing attributes an object based on class name and UUID
