This project is the first step of a big project with the goal of deploy on your server a simple copy of the AirBnB website
This fisrt step is manipulate a powerful storage system. This storage engine will give us an abstraction between “My object” and “How they are stored and persisted”, at the end of this project we will have:
- Create your data model
- Manage (create, update, destroy, etc) objects via a console / command interpreter
- Store and persist objects to a file (JSON file)
A command interpreter allows the user to interact with a program using commands in the form of text lines. In this project we are going to use a command interpreter diferrent methods (table class) to a differents types of classes (table methos)
| Class | Attributes |
|---|---|
| BaseModel | id, created_at, updated_at |
| User | email, password, first_name, last_name |
| Place | city_id, user_id, name, description, number_rooms, number_bathrooms, max_guest, price_by_night, latitude, longitude, amenity_ids |
| State | ame |
| City | state_id, name |
| Amenity | name |
| Review | place_id, user_id: string, text |
| Methods | Syntax |
|---|---|
| Create | create (class name) |
| Show | show (class name) (id) |
| Destroy | destroy (class name) (id) |
| All | all (class name) (optional) |
| (class name).(method) | (class name).(method)(arguments of the method) |
To start use the console is necesary execute the file console.py
# execute the file
$ AirBnB_clone ./console.py
(hbnb)
To use the console is necesary follow the syntax of the table methods in base of the classes of the table class
(hbnb) create User
f65e5ae6-b555-44f4-9a36-15003963b63f
Let's start creating classes.
(hbnb) create User
f65e5ae6-b555-44f4-9a36-15003963b63f
(hbnb) create Place
f324857e-d73b-424d-b555-ab7795ddb1c9
Now show One of the classes and destoy it.
(hbnb) show User f65e5ae6-b555-44f4-9a36-15003963b63f
[User] (f65e5ae6-b555-44f4-9a36-15003963b63f) {'created_at': datetime.datetime(2019, 11, 13, 10, 30, 20, 674305), 'updated_at': datetime.datetime(2019, 11, 13, 10, 30, 20, 674368), 'id': 'f65e5ae6-b555-44f4-9a36-15003963b63f'}
(hbnb) destroy User f65e5ae6-b555-44f4-9a36-15003963b63f
(hbnb) show User f65e5ae6-b555-44f4-9a36-15003963b63f
** no instance found **
Finally updtate an attribute of a class and show it
(hbnb) update Place f324857e-d73b-424d-b555-ab7795ddb1c9 latitude 5.6
(hbnb) all
["[Place] (9ba0e72b-e2f5-4709-89c6-a674f545aa79) {'name': 'Betty', 'age': '89', 'id': '9ba0e72b-e2f5-4709-89c6-a674f545aa79', 'created_at': datetime.datetime(2019, 11, 13, 9, 30, 37, 403455), 'first_name': 'John', 'latitude': 89.0, 'updated_at': datetime.datetime(2019, 11, 13, 9, 40, 5, 280079)}", "[Place] (f324857e-d73b-424d-b555-ab7795ddb1c9) {'id': 'f324857e-d73b-424d-b555-ab7795ddb1c9', 'created_at': datetime.datetime(2019, 11, 13, 10, 30, 28, 366510), 'latitude': 5.6, 'updated_at': datetime.datetime(2019, 11, 13, 10, 31, 47, 761770)}"]
