📝 Description

This repository serves as the foundational component for a comprehensive project aimed at creating an Airbnb clone.
It marks the initial phase of this student undertaking, introducing a powerful backend interface, often referred to as a console.
The console empowers users with the ability to effortlessly manage various program data, including object creation, updates, deletions, and efficient file storage management.
By leveraging JSON serialization and deserialization, data persistence is seamlessly maintained across multiple sessions, setting the stage for subsequent projects like HTML/CSS templating, database integration, API development, and front-end integration.

🔨 Tech stack

📋 Requirements

All the files will be interpreted/compiled on Ubuntu 20.04 LTS using python3 (version 3.8.5).
The first line of all the files should be exactly #!/usr/bin/python3.
The code should use the pycodestyle (version 2.7.*).
All the files must be executable.
All the functions, classes and modules should have a documentation .
A documentation is not a simple word, it’s a real sentence explaining what’s the purpose...
You have to use the unittest module.
All your unittest files should be inside a folder tests.
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.
All your tests should be executed by using this command: python3 -m unittest discover tests

🎓 Instructions

Task 0. README, AUTHORS

Write a README.md:
- Description of the project.
- description of the command interpreter:
  - How to start it.
  - How to use it.
  - Examples.
You should have an AUTHORS file at the root of your repository, listing all individuals having contributed content to the repository. For format, reference Docker’s AUTHORS page.
You should use branches and pull requests on GitHub - it will help you as team to organize your work.

Repo:

GitHub repository: holbertonschool-AirBnB_clone.
File: README.md, AUTHORS.

Task 1. Be pycodestyle compliant!

Write beautiful code that passes the pycodestyle checks.

Repo:

GitHub repository: holbertonschool-AirBnB_clone.
File: console.py, models/base_model.py, models/user.py, models/place.py, models/state.py, models/city.py, models/amenity.py, models/review.py, models/engine/file_storage.py.

Task 2. Unittests

All your files, classes, functions must be tested with unit tests

guillaume@ubuntu:~/AirBnB$ python3 -m unittest discover tests

Task 3. BaseModel

Write a class BaseModel that defines all common attributes/methods for other classes:

models/base_model.py.
Public instance attributes:
- id: string - assign with an uuid when an instance is created:
  - You can use uuid.uuid4() to generate unique id but don’t forget to convert to a string.
  - The goal is to have unique id for each BaseModel.
- created_at: datetime - assign with the current datetime when an instance is created.
- updated_at: datetime - assign with the current datetime when an instance is created and it will be updated every time you change your object.
__str__: should print: [<class name>] (<self.id>) <self.__dict__>.
Public instance methods:
- save(self): updates the public instance attribute updated_at with the current datetime.
- to_dict(self): returns a dictionary containing all keys/values of __dict__ of the instance:
  - By using self.__dict__, only instance attributes set will be returned.
  - a key __class__ must be added to this dictionary with the class name of the object.
  - created_at and updated_at must be converted to string object in ISO format:
    - format: %Y-%m-%dT%H:%M:%S.%f (ex: 2017-06-14T22:31:03.285259).
    - you can use isoformat() of datetime object.
  - This method will be the first piece of the serialization/deserialization process: create a dictionary representation with “simple object type” of our BaseModel.

guillaume@ubuntu:~/AirBnB$ cat test_base_model.py

from models.base_model import BaseModel

my_model = BaseModel()
my_model.name = "My First Model"

my_model.save()
print(my_model)
my_model_json = my_model.to_dict()
print(my_model_json)
print("JSON of my_model:")
for key in my_model_json.keys():
    print("\t{}: ({}) - {}".format(key, type(my_model_json[key]), my_model_json[key]))

Task 4. Create BaseModel from dictionary

Previously we created a method to generate a dictionary representation of an instance (method to_dict()).

Now it’s time to re-create an instance with this dictionary representation.

<class 'BaseModel'> -> to_dict() -> <class 'dict'> -> <class 'BaseModel'>

Update models/base_model.py:

__init__(self, *args, **kwargs):
- You will use *args, **kwargs arguments for the constructor of a BaseModel. (more information inside the AirBnB clone concept page).
- *args won’t be used.
- If kwargs is not empty:
  - Each key of this dictionary is an attribute name (Note __class__ from kwargs is the only one that should not be added as an attribute. See the example output, below).
  - Each value of this dictionary is the value of this attribute name.
- Warning: created_at and updated_at are strings in this dictionary, but inside your BaseModel instance is working with datetime object. You have to convert these strings into datetime object. Tip: you know the string format of these datetime.
- Otherwise:
  - Create id and created_at as you did previously (new instance).

guillaume@ubuntu:~/AirBnB$ cat test_base_model_dict.py
#!/usr/bin/python3
from models.base_model import BaseModel

my_model = BaseModel()
my_model.name = "My_First_Model"
my_model.my_number = 89
print(my_model.id)
print(my_model)
print(type(my_model.created_at))
print("--")
my_model_json = my_model.to_dict()
print(my_model_json)
print("JSON of my_model:")
for key in my_model_json.keys():
    print("\t{}: ({}) - {}".format(key, type(my_model_json[key]), my_model_json[key]))

print("--")
my_new_model = BaseModel(**my_model_json)
print(my_new_model.id)
print(my_new_model)
print(type(my_new_model.created_at))

print("--")
print(my_model is my_new_model)

Task 5. Store first object

Now we can recreate a BaseModel from another one by using a dictionary representation:

<class 'BaseModel'> -> to_dict() -> <class 'dict'> -> <class 'BaseModel'>

It’s great but it’s still not persistent: every time you launch the program, you don’t restore all objects created before… The first way you will see here is to save these objects to a file.

Writing the dictionary representation to a file won’t be relevant:

Python doesn’t know how to convert a string to a dictionary (easily).
It’s not human readable.
Using this file with another program in Python or other language will be hard.

So, you will convert the dictionary representation to a JSON string. JSON is a standard representation of a data structure. With this format, humans can read and all programming languages have a JSON reader and writer.

Now the flow of serialization-deserialization will be:

<class 'BaseModel'> -> to_dict() -> <class 'dict'> -> JSON dump -> <class 'str'> -> FILE -> <class 'str'> -> JSON load -> <class 'dict'> -> <class 'BaseModel'>

Magic right?

Terms:

Simple Python data structure: Dictionaries, arrays, number and string. ex: { '12': { 'numbers': [1, 2, 3], 'name': "John" } }.
JSON string representation: String representing a simple data structure in JSON format. ex: '{ "12": { "numbers": [1, 2, 3], "name": "John" } }'.

Write a class FileStorage that serializes instances to a JSON file and deserializes JSON file to instances:

models/engine/file_storage.py.
Private class attributes:
- __file_path: string - path to the JSON file (ex: file.json)
- __objects: dictionary - empty but will store all objects by <class name>.id (ex: to store a BaseModel object with id=12121212, the key will be BaseModel.12121212).
Public instance methods:
- all(self): returns the dictionary __objects.
- new(self, obj): sets in __objects the obj with key <obj class name>.id.
- save(self): serializes __objects to the JSON file (path: __file_path).
- reload(self): deserializes the JSON file to __objects (only if the JSON file (__file_path) exists ; otherwise, do nothing. If the file doesn’t exist, no exception should be raised).

Update models/__init__.py: to create a unique FileStorage instance for your application.

Import file_storage.py.
Create the variable storage, an instance of FileStorage.
Call reload() method on this variable.

Update models/base_model.py: to link your BaseModel to FileStorage by using the variable storage.

Import the variable storage.
In the method save(self):
- Call save(self) method of storage.
__init__(self, *args, **kwargs):
- If it’s a new instance (not from a dictionary representation), add a call to the method new(self) on storage.

from models import storage
from models.base_model import BaseModel

all_objs = storage.all()
print("-- Reloaded objects --")
for obj_id in all_objs.keys():
    obj = all_objs[obj_id]
    print(obj)

print("-- Create a new object --")
my_model = BaseModel()
my_model.name = "My_First_Model"
my_model.my_number = 89
my_model.save()
print(my_model)

Task 6. Console 0.0.1

Write a program called console.py that contains the entry point of the command interpreter:

You must use the module cmd.
Your class definition must be: class HBNBCommand(cmd.Cmd):
Your command interpreter should implement:
- quit and EOF to exit the program.
- help (this action is provided by default by cmd but you should keep it updated and documented as you work through tasks).
- a custom prompt: (hbnb).
- an empty line + ENTER shouldn’t execute anything.
Your code should not be executed when imported.

Warning:

You should end your file with:

if __name__ == '__main__':
    HBNBCommand().cmdloop()

To make your program executable except when imported. Please don’t add anything around - the Checker won’t like it otherwise.

guillaume@ubuntu:~/AirBnB$ ./console.py

Task 7. Console 0.1

Update your command interpreter (console.py) to have these commands:

create: creates a new instance of BaseModel, saves it (to the JSON file) and prints the id. Ex: $ create BaseModel.
- If the class name is missing, print ** class name missing ** (ex: $ create)
- If the class name doesn’t exist, print ** class doesn't exist ** (ex: $ create MyModel).
show: Prints the string representation of an instance based on the class name and id. ex: $ show BaseModel 1234-1234-1234.
- If the class name is missing, print ** class name missing ** (ex: $ show).
- If the class name doesn’t exist, print ** class doesn't exist ** (ex: $ show MyModel).
- If the id is missing, print ** instance id missing ** (ex: $ show BaseModel).
- If the instance of the class name doesn’t exist for the id, print ** no instance found ** (ex: $ show BaseModel 121212).
destroy: Deletes an instance based on the class name and id (save the change into the JSON file). ex: $ destroy BaseModel 1234-1234-1234.
- If the class name is missing, print ** class name missing ** (ex: $ destroy).
- If the class name doesn’t exist, print ** class doesn't exist ** (ex: $ destroy MyModel).
- If the id is missing, print ** instance id missing ** (ex: $ destroy BaseModel).
- If the instance of the class name doesn’t exist for the id, print ** no instance found ** (ex: $ destroy BaseModel 121212).
all: prints all string representation of all instances based or not on the class name. ex: $ all BaseModel or $ all.
- The printed result must be a list of strings (like the example below).
- If the class name doesn’t exist, print ** class doesn't exist ** (ex: $ all MyModel).
update: updates an instance based on the class name and id by adding or updating attribute (save the change into the JSON file). ex: $ update BaseModel 1234-1234-1234 email "aibnb@mail.com".
- Usage: update <class name> <id> <attribute name> "<attribute value>".
- Only one attribute can be updated at the time.
- You can assume the attribute name is valid (exists for this model).
- The attribute value must be casted to the attribute type.
- If the class name is missing, print ** class name missing ** (ex: $ update).
- If the class name doesn’t exist, print ** class doesn't exist ** (ex: $ update MyModel).
- If the id is missing, print ** instance id missing ** (ex: $ update BaseModel).
- If the instance of the class name doesn’t exist for the id, print ** no instance found ** (ex: $ update BaseModel 121212).
- If the attribute name is missing, print ** attribute name missing ** (ex: $ update BaseModel existing-id).
- If the value for the attribute name doesn’t exist, print ** value missing ** (ex: $ update BaseModel existing-id first_name).
- All other arguments should not be used (ex: $ update BaseModel 1234-1234-1234 email "aibnb@mail.com" first_name "Betty" = $ update BaseModel 1234-1234-1234 email "aibnb@mail.com").
- id, created_at and updated_at cant’ be updated. You can assume they won’t be passed in the update command.
- Only “simple” arguments can be updated: string, integer and float. You can assume nobody will try to update list of ids or datetime.

Let’s add some rules:

You can assume arguments are always in the right order.
Each arguments are separated by a space.
A string argument with a space must be between double quote.
The error management starts from the first argument to the last one.

Task 8. First User

Write a class User that inherits from BaseModel:

models/user.py.
Public class attributes:
- email: string - empty string
- password: string - empty string
- first_name: string - empty string
- last_name: string - empty string

Update FileStorage to manage correctly serialization and deserialization of User.

Update your command interpreter (console.py) to allow show, create, destroy, update and all used with User.

Task 10. Console 1.0

Update FileStorage to manage correctly serialization and deserialization of all our new classes: Place, State, City, Amenity and Review.

Update your command interpreter (console.py) to allow those actions: show, create, destroy, update and all with all classes created previously.

Enjoy your first console!

No unittests needed for the console.
