Background Context

Environment variables will be your best friend for this project!

  1. HBNB_ENV: running environment. It can be “dev” or “test” for the moment (“production” soon!)
  2. HBNB_MYSQL_USER: the username of your MySQL
  3. HBNB_MYSQL_PWD: the password of your MySQL
  4. HBNB_MYSQL_HOST: the hostname of your MySQL
  5. HBNB_MYSQL_DB: the database name of your MySQL
  6. HBNB_TYPE_STORAGE: the type of storage used. It can be “file” (using FileStorage) or db (using DBStorage)
  7. HBNB - The Console

    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, to manage program data. Console commands allow the user to create, update, and destroy objects, as well as manage file storage. Using a system of JSON serialization/deserialization, storage is persistent between sessions.

    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$ ./console.py
    
    1. When this command is run the following prompt should appear:
    (hbnb)
    
    1. 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
