In my case, my entity, Page, had an updated_at column, which Rails automatically updates anytime a record is saved. I wanted to maintain a view_count, but I didn't want the updated_at attribute to be changed each time the view_count was incremented. I used update_counters to achieve this. In my 'show' action: Page.update_counters(params[:id], :view_count => 1) @page = Page.find(params[:id] The update_counters method automatically saves the record and skips the automagic timestamp updates. This works for Rails 2.3.2 I would recommend using the update_counters method.
