How to make own decorator to view in Flask
from functools import wraps

# нужен декоратор на декорируемую функцию, т.к. app.route - составляет таблицу view - и ему нужны уникальные ссылки на функции.
# Если не добавить подобный декоратор, то ссылки будут одинаковые - на функцию decorated_view
# wraps - использует создание экземпляра объекта partial - (каждый экземпляр обладает уникальной ссылкой и ведёт себя как функция)
