I want to add a _count to a couple of my models but this is not a new relationship so the numbers will not start at zero. I have tried just adding an update_attribute to my migration with the current count but for some reason the DB will not take the new number.
Does the _count field have a protection on it so people can not tamper with it? What is the proper way to add a _count field to relationships that already exist in production i.e. is there a Rails way of doing it?
