What is the most DRY way to prevent deletion of a parent if children exist?
I assume it would be a before_destroy :check_that_no_child_exists But an object might have several different types of children and we would ideally want to iterate through all the has_many's with just one command. Is there an elegant way of doing this, and returning a helpful error message indicating which type of child exists? I'm amazed that Rails still doesn't seem to have a default facility for this as its a very basic requirement.
