If you call a model method with heavy calculations or database queries multiple times in the request-response cycle, the performance of the view might be very slow. In this recipe, you will learn about a pattern that you can use to cache the return value of a method for later repetitive use. Note that we are not using the Django cache framework here, only what Python provides us by default.
