Counter cache not updating

The most efficient way to implement low-level caching is using the method.

One recommendation is to simply be explicit in a comment, like: Sometimes you need to cache a particular value or query result instead of caching view fragments.

Rails' caching mechanism works great for storing any kind of information.

Caching means to store content generated during the request-response cycle and to reuse it when responding to similar requests.

Caching is often the most effective way to boost an application's performance.

Dynamic web applications usually build pages with a variety of components not all of which have the same caching characteristics.

When different parts of the page need to be cached and expired separately you can use Fragment Caching.

In order to correctly invalidate the cache, you need to properly define the caching dependencies.
