django decorators

Django framework has used some design patterns. There is a directory called decorator which currently has two decorators: (decorator is just a method which dynamically adds additional functionality to original method depending on the situation)

  • funcA = login_required(funcA)
    This replaces the funcA with a function which checks if the user is logged in and calls original function if the user is indeed logged in and redirects the anonymous users to login page.
  • funcB=cache_page(funcB,cache_timeout,key_prefix)
    The original function is changed to look into the cached pages.
