00:00Every time a user accesses this page, posts are requested from the server.

00:12To load them faster, I'm using cache.

00:17In this video, I'll explain how.

00:21In the backend, I have created for Django a file called cache.

00:33In this file, I have created a CacheManager class to manage the cache for posts.

00:47When I create an instance for this class CacheManager,

00:57I'm providing the user ID and the page number to create a unique cache for each request.

01:12Because I need to save in cache only the user posts and only posts for a page.

01:27I'm creating a unique cache key based on user ID and page number.

01:39Next, I'm requesting the posts from the database.

01:47If posts exist, I'm saving them in a cache using this code.

01:58When the user accesses the page where are displayed the posts,

02:12I'm verifying first if the cache exists for that user and the page number.

02:23If cache exists, this means I will return this cache.

02:33In this way, I will avoid to make all these verifications and request the data from the database.

02:53In this way, I will avoid to make all these verifications and request the data from the database.

03:03In this way, I will avoid to make all these verifications and request the data from the database.
