Cache only the main content in rails

Question

Using Rails 3.1.1 and Heroku.

I believe this should be a fairly easy fix but I cannot find (and easily verify) how to do this. I have a very slow controller (6 sec)

Answer 1

Use fragment caching, and don't load things in the controller.

If you have a very complex query, let it live in the controller as a scope, and only evaluate it in the view.

If you have a complex process to do so the query must be executed, use a helper method.

If you manage to just load lazy queries in the controller, if the cache is hit none of them will be executed.
