AirBnB clone - The console

Background Context

First step: Write a command interpreter to manage your AirBnB objects.

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

What’s a command interpreter?

Do you remember the Shell? It’s exactly the same 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

Requirements Python Scripts

• Allowed editors: vi, vim, emacs
• All your files will be interpreted/compiled on Ubuntu 14.04 LTS using python3 (version 3.4.3)
• All your files should end with a new line
• The first line of all your files should be exactly #!/usr/bin/python3
• A README.md file, at the root of the folder of the project, is mandatory
• Your code should use the PEP 8 style (version 1.7 or more)
• All your files must be executable
• The length of your files will be tested using wc
• All your modules should have a documentation (python3 -c 'print(import("my_module").doc)')
• All your classes should have a documentation (python3 -c 'print(import("my_module").MyClass.doc)')
• All your functions (inside and outside a class) should have a documentation (python3 -c 'print(import("my_module").my_function.doc)' and python3 -c 'print(import("my_module").-MyClass.my_function.doc)')

Requirements Python Unit Tests

• Allowed editors: vi, vim, emacs
• All your files should end with a new line
• All your test files should be inside a folder tests
• You have to use the unittest module
• All your test files should be python files (extension: .py)
• All your test files and folders should start by test_
• Your file organization in the tests folder should be the same as your project e.g., For models/base_model.py, unit tests must be in: tests/test_models/test_base_model.py e.g., For models/user.py, unit tests must be in: tests/test_models/test_user.py
• All your tests should be executed by using this command: python3 -m unittest discover tests
• You can also test file by file by using this command: python3 -m unittest tests/test_models/test_base_model.py
• All your modules should have a documentation (python3 -c 'print(import("my_module").doc)')
• All your classes should have a documentation (python3 -c 'print(import("my_module").MyClass.doc)')
• All your functions (inside and outside a class) should have a documentation (python3 -c 'print(import("my_module").my_function.doc)' and python3 -c 'print(import("my_module").MyClass.my_function.doc)')
• We strongly encourage you to work together on test cases, so that you don’t miss any edge case

HOW THE CONSOLE WORKS

Steps for testing the console

1. Clone the repository with HTTPS:

$ git clone https://github.com/lowercaselife/AirBnB_clone.git

2. Go to folder AirBnB_clone

$ cd AirBnB_clone

3. Run the consol file

$ ./console.py

Alfter in you screen can show the prompt of the terminal:

(hbnb)

Command for test the console

the command that you can type are:

• help ó ?: this show the help avalible for command and the commands.

(hbnb)?

Documented commands (type help <topic>):
========================================
EOF  all  create  destroy  help  quit  show  update

(hbnb)help

Documented commands (type help <topic>):
========================================
EOF  all  create  destroy  help  quit  show  update

(hbnb)

• EOF and quit: this commands are for exit the console, the EOF is the signal get to press the key combination Ctrl + d

(hbnb)quit
