All I am trying to do, is in an easy/light way...whenever the PostsController#Show
action is fired, to increment the post.views
or post.view_count
column. I don't want to have to do anything too heavy.
It feels like the native counter_cache
would be perfect...but that is specifically for association object count.
Anyway I can re-purpose that? Or use the underlying concepts in the way I want?
You can't use counter cache directly, but you can use the underlying increment function. See the documentation. To do what you say, you'd want:
Post.increment_counter(:view_count, post.id)
This issues a single SQL update
command.
