Decorators

Create domain/models.py file for domain modeling.

Create a Movie class with name and customer_age class fields.

name field must be str type, customer_age field must be int type.

Remember to implement unit tests for the Movie class, use pytest for tests.

Create a function called movie_factory with name and customer_age arguments.

Function must be located in domain/models.py.

The name argument must be str type, customer_age argument must be int type.

Factory should return the type as a Movie class object.

Do not forget to implement unit tests for the movie_factory function, use pytest for tests.

Create a decorator called age_limit_6plus, the argument of the decorator is a Callable, as usual decorators.

Remember that the Movie model is located in domain/models.py and is already ready from the previous task, no need to implement it again.

The decorator must be located in utils/decorator.py.

The decorator must check movie.customer_age with their proper conditions.

The return type of decorator must be Callable from typing. Read more: Annotating callables

If customer_age doesn’t satisfy the condition, the return can be “Sorry, you are not old enough to watch {movie.name}!”. If it does, the return can be “You are allowed to watch {movie.name}!”.

Create service/tickets.py where you need to put your service logic.

Create a function called buy_ticket_for_children() with a movie argument which must be Movie type.

The function must return f"You are allowed to watch {movie.name}!"

Use age_limit_6plus decorator for validating buy_ticket_for_children()

Remember to implement unit tests for the decorator, success, and fail cases, use pytest for tests.

Create a decorator called age_limit_13plus the argument of the decorator is a Callable, as usual decorators.

Remember that the Movie model is located in domain/models.py and is already ready from the previous task, no need to implement it again.

The decorator must be located in utils/decorator.py.

The decorator must check movie.customer_age with their proper conditions.

The return type of decorator must be Callable from typing. Read more: Annotating callables

If customer_age doesn’t satisfy the condition, the return can be “Sorry, you are not old enough to watch {movie.name}!”. If it does, the return can be “You are allowed to watch {movie.name}!”.

In service/tickets.py, create a function called buy_ticket_for_teens() with a movie argument which must be Movie type.

The function must return f"You are allowed to watch {movie.name}!"

Use age_limit_13plus decorator for validating buy_ticket_for_teens()

Remember to implement unit tests for the decorator, success, and fail cases, use pytest for tests.
