An AirBnB clone.
HBnB 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.
HBnB 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 |

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 |
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
.
The console is a command line interpreter that permits management of the backend
of HBnB. It can be used to handle and manipulate all classes utilized by
the application (achieved by calls on the storage
object defined above).
The HBnB 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
$
The HBnB console supports the following commands:
- create
- Usage:
create <class>
- Usage:
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

- show
- Usage:
show <class> <id>
or<class>.show(<id>)
- Usage:
Prints the string representation of a class instance based on a given id.

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