0x00. AirBnB clone - The console

Concepts

For this project, students are expected to look at these concepts:

Background Context

Welcome to the AirBnB clone project!

Before starting, please read theAirBnBconcept page.

First step: Write a command interpreter to manage your AirBnB objects.

This is the first step towards building your first full web application: theAirBnB clone. This first step is very important because you will use what you build during this project with all other following projects: HTML/CSS templating, database storage, API, front-end integration...

Each task is linked and will help you to:

put in place a parent class (calledBaseModel) to take care of the initialization, serialization and deserialization of your future instances
create a simple flow of serialization/deserialization: Instance <-> Dictionary <-> JSON string <-> file
create all classes used for AirBnB (User,State,City,Place...) that inherit fromBaseModel
create the first abstracted storage engine of the project: File storage.
create all unittests to validate all our classes and storage engine

What's a command interpreter?

Do you remember the Shell? It's exactly the same but limited to a specific use-case. In our case, we want to be able to manage the objects of our project:

Create a new object (ex: a new User or a new Place)
Retrieve an object from a file, a database etc...
Do operations on objects (count, compute stats, etc...)
Update attributes of an object
Destroy an object

Requirements

Python Scripts

Allowed editors:vi,vim,emacs
All your files will be interpreted/compiled on Ubuntu 20.04 LTS using python3 (version 3.8.5)
All your files should end with a new line
The first line of all your files should be exactly#!/usr/bin/python3
AREADME.mdfile, at the root of the folder of the project, is mandatory
Your code should use the pycodestyle (version2.8.*)

All your functions (inside and outside a class) should have a documentation (python3 -c 'print(__import__("my_module").my_function.__doc__)'andpython3 -c 'print(__import__("my_module").MyClass.my_function.__doc__)')
A documentation is not a simple word, it's a real sentence explaining what's the purpose of the module, class or method (the length of it will be verified)

Python Unit Tests

Allowed editors:vi,vim,emacs

You have to use theunittest module
All your test files should be python files (extension:.py)
All your test files and folders should start bytest_
Your file organization in the tests folder should be the same as your project
e.g., Formodels/base_model.py, unit tests must be in:tests/test_models/test_base_model.py
e.g., Formodels/user.py, unit tests must be in:tests/test_models/test_user.py
All your tests should be executed by using this command:python3 -m unittest discover tests
You can also test file by file by using this command:python3 -m unittest tests/test_models/test_base_model.py
All your modules should have a documentation (python3 -c 'print(__import__("my_module").__doc__)')
All your classes should have a documentation (python3 -c 'print(__import__("my_module").MyClass.__doc__)')
All your functions (inside and outside a class) should have a documentation (python3 -c 'print(__import__("my_module").my_function.__doc__)'andpython3 -c 'print(__import__("my_module").MyClass.my_function.__doc__)')
We strongly encourage you to work together on test cases, so that you don't miss any edge case

GitHub

There should be one project repository per group. If you clone/fork/whatever a project repository with the same name before the second deadline, you risk a 0% score.

More Info

Execution

Your shell should work like this in interactive mode:

$ ./console.py
(hbnb) help

Documented commands (type help <topic>):
========================================
EOF  help  quit

(hbnb)
(hbnb)
(hbnb) quit
$

But also in non-interactive mode: (like the Shell project in C)

$ echo "help" | ./console.py
(hbnb)

Documented commands (type help <topic>):
========================================
EOF  help  quit
(hbnb)
$
$ cat test_help
help
$
$ cat test_help | ./console.py
(hbnb)

Documented commands (type help <topic>):
========================================
EOF  help  quit
(hbnb)
$

All tests should also pass in non-interactive mode:$ echo "python3 -m unittest discover tests" | bash

3. BaseModel

mandatory

Score:50.00%(Checks completed: 100.00%)

Write a classBaseModelthat defines all common attributes/methods for other classes:

models/base_model.py
Public instance attributes:
- id: string - assign with anuuidwhen an instance is created:
  - you can useuuid.uuid4()to generate uniqueidbut don't forget to convert to a string
  - the goal is to have uniqueidfor eachBaseModel
- 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 attributeupdated_atwith the current datetime
- to_dict(self): returns a dictionary containing all keys/values of__dict__of the instance:
  - by usingself.__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_atandupdated_atmust 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 useisoformat()ofdatetimeobject
  - This method will be the first piece of the serialization/deserialization process: create a dictionary representation with "simple object type" of ourBaseModel

4. Create BaseModel from dictionary

mandatory

Score:50.00%(Checks completed: 100.00%)

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

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

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

Updatemodels/base_model.py:

__init__(self, *args, **kwargs):
- you will use*args, **kwargsarguments for the constructor of aBaseModel. (more information inside theAirBnB cloneconcept page)
- *argswon't be used
- ifkwargsis not empty:
  - each key of this dictionary is an attribute name (Note__class__fromkwargsis 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_atandupdated_atare strings in this dictionary, but inside yourBaseModelinstance is working withdatetimeobject. You have to convert these strings intodatetimeobject. Tip: you know the string format of these datetime
- otherwise:
  - createidandcreated_atas 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)

5. Store first object

mandatory

Score:40.00%(Checks completed: 80.00%)

Now we can recreate aBaseModelfrom 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 classFileStoragethat 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 aBaseModelobject withid=12121212, the key will beBaseModel.12121212)
Public instance methods:
- all(self): returns the dictionary__objects
- new(self, obj): sets in__objectstheobjwith key<obj class name>.id
- save(self): serializes__objectsto 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)

Updatemodels/__init__.py: to create a uniqueFileStorageinstance for your application

importfile_storage.py
create the variablestorage, an instance ofFileStorage
callreload()method on this variable

Updatemodels/base_model.py: to link yourBaseModeltoFileStorageby using the variablestorage

import the variablestorage
in the methodsave(self):
- callsave(self)method ofstorage
__init__(self, *args, **kwargs):
- if it's a new instance (not from a dictionary representation), add a call to the methodnew(self)onstorage

- 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 andid. 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 theidis missing, print** instance id missing **(ex:$ show BaseModel)
- If the instance of the class name doesn't exist for theid, print** no instance found **(ex:$ show BaseModel 121212)
destroy: Deletes an instance based on the class name andid(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 theidis missing, print** instance id missing **(ex:$ destroy BaseModel)
- If the instance of the class name doesn't exist for theid, 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 BaseModelor$ 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 andidby adding or updating attribute (save the change into the JSON file). Ex:$ update BaseModel 1234-1234-1234 email "[email protected]".
- 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 theidis missing, print** instance id missing **(ex:$ update BaseModel)
- If the instance of the class name doesn't exist for theid, 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 "[email protected]" first_name "Betty"=$ update BaseModel 1234-1234-1234 email "[email protected]")
- id,created_atandupdated_atcant' be updated. You can assume they won't be passed in theupdatecommand
- 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

17. Unittests for the Console!

#advanced

Score:0.00%(Checks completed: 0.00%)

Write all unittests forconsole.py, all features!

For testing the console, you should "intercept" STDOUT of it, wehighlyrecommend you to use:

with patch('sys.stdout', new=StringIO()) as f:
    HBNBCommand().onecmd("help show")

Otherwise, you will have to re-write the console by replacingprecmdbydefault.
