AirBnB Clone V.2 - MYSQL

Synopsis

This is the 2nd version of our AirBnB clone project. We will be using a MySQL database with the following environmental variables:

• HBNB_ENV: running environment. It can be “dev” or “test” for the moment (“production” soon!)
• HBNB_MYSQL_USER: the username of your MySQL
• HBNB_MYSQL_PWD: the password of your MySQL
• HBNB_MYSQL_HOST: the hostname of your MySQL
• HBNB_MYSQL_DB: the database name of your MySQL
• HBNB_TYPE_STORAGE: the type of storage used. It can be “file” (using FileStorage) or db (using DBStorage)

Environment

This project is interpreted/tested on Ubuntu 14.04 LTS using python3 (version 3.4.3)

Installation

• 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:

• amenity.py
• city.py
• place.py
• review.py
• state.py
• user.py

/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

To check the status of your api, open 2 terminals First window:

ubuntu:~/Airbnb_clone_v3$ HBNB_MYSQL_USER=hbnb_dev HBNB_MYSQL_PWD=hbnb_dev_pwd HBNB_MYSQL_HOST=localhost HBNB_MYSQL_DB=hbnb_dev_db HBNB_TYPE_STORAGE=db HBNB_API_HOST=0.0.0.0 HBNB_API_PORT=5000 python3 -m api.v1.app
 * Running on http://0.0.0.0:5000/ (Press CTRL+C to quit)
...

Second window:

ubuntu:~/Airbnb_clone_v3$ curl -X GET http://0.0.0.0:5000/api/v1/status
{
  "status": "OK"
}

To check whether a State(s) exists:

ubuntu:~/Airbnb_clone_v3$ curl -X GET http://0.0.0.0:5000/api/v1/states/
{
  "__class__": "State", 
  "created_at": "2017-04-14T00:00:02", 
  "id": "8f165686-c98d-46d9-87d9-d6059ade2d99", 
  "name": "Louisiana", 
  "updated_at": "2017-04-14T00:00:02"
}
...

If State(s) don't exist, it should return a 404 error
