HolbertonBnB

An AirBnB clone.

Description 🏠

HolbertonBnB is a complete web application, integrating database storage, a back-end API, and front-end interfacing in a clone of AirBnB.

The project currently only implements the back-end console.

Classes 🆑

HolbertonBnB utilizes the following classes:

	BaseModel	FileStorage	User	State	City	Amenity	Place	Review
PUBLIC INSTANCE ATTRIBUTES	`id` `created_at` `updated_at`		Inherits from `BaseModel`	Inherits from `BaseModel`	Inherits from `BaseModel`	Inherits from `BaseModel`	Inherits from `BaseModel`	Inherits from `BaseModel`
PUBLIC INSTANCE METHODS	`save` `to_dict`	`all` `new` `save` `reload`	""	""	""	""	""	""
PUBLIC CLASS ATTRIBUTES			`email` `password` `first_name` `last_name`	`name`	`state_id` `name`	`name`	`city_id` `user_id` `name` `description` `number_rooms` `number_bathrooms` `max_guest` `price_by_night` `latitude` `longitude` `amenity_ids`	`place_id` `user_id` `text`
PRIVATE CLASS ATTRIBUTES		`file_path` `objects`

Storage 🛄

The above classes are handled by the abstracted storage engine defined in the FileStorage class.

Every time the backend is initialized, HolbertonBnB instantiates an instance of FileStorage called storage. The storage object is loaded/re-loaded from any class instances stored in the JSON file file.json. As class instances are created, updated, or deleted, the storage object is used to register corresponding changes in the file.json.

Console 💻

The console is a command line interpreter that permits management of the backend of HolbertonBnB. It can be used to handle and manipulate all classes utilized by the application (achieved by calls on the storage object defined above).

Using the Console

The HolbertonBnB console can be run both interactively and non-interactively. To run the console in non-interactive mode, pipe any command(s) into an execution of the file console.py at the command line.

$ echo "help" | ./console.py
(hbnb) 
Documented commands (type help <topic>):
========================================
EOF  all  count  create  destroy  help  quit  show  update

(hbnb) 
$

Alternatively, to use the HolbertonBnB console in interactive mode, run the file console.py by itself:

$ ./console.py

While running in interactive mode, the console displays a prompt for input:

$ ./console.py
(hbnb)

To quit the console, enter the command quit, or input an EOF signal (ctrl-D).

$ ./console.py
(hbnb) quit
$

$ ./console.py
(hbnb) EOF
$

Console Commands

The HolbertonBnB console supports the following commands:

create
- Usage: create <class>

Creates a new instance of a given class. The class' ID is printed and the instance is saved to the file file.json.

$ ./console.py
(hbnb) create BaseModel
119be863-6fe5-437e-a180-b9892e8746b8
(hbnb) quit
$ cat file.json ; echo ""
{"BaseModel.119be863-6fe5-437e-a180-b9892e8746b8": {"updated_at": "2019-02-17T2
1:30:42.215277", "created_at": "2019-02-17T21:30:42.215277", "__class__": "Base

all
- Usage: all or all <class> or <class>.all()

count
- Usage: count <class> or <class>.count()

Retrieves the number of instances of a given class.

update
- Usage: update <class> <id> <attribute name> "<attribute value>" or <class>.update(<id>, <attribute name>, <attribute value>) or <class>.update( <id>, <attribute dictionary>).

Updates a class instance based on a given id with a given key/value attribute pair or dictionary of attribute pairs. If update is called with a single key/value attribute pair, only "simple" attributes can be updated (ie. not id, created_at, and updated_at). However, any attribute can be updated by providing a dictionary.

Testing 📏

Unittests for the HolbertonBnB project are defined in the tests folder. To run the entire test suite simultaneously, execute the following command:

$ python3 unittest -m discover tests

Alternatively, you can specify a single test file to run at a time:
