Don't Use to_formatted_s(:db) on an Array of IDs
I thought using to_formatted_s(:db) on an array of ids would separate them with commas in a nice way. Wrong. It does, but it also changes the numbers.
Wrong
[60, 271, 280, 283].to_formatted_s(:db) # => "121,543,561,567" # Completely different numbers!
Instead, use the join method:
Right
[60, 271, 280, 283].join(",") # => "60,271,280,283" # Much better
I think this has to do with (:db) being used for formatting dates but I’m not sure.

RE: Don't Use to_formatted_s(:db) on an Array of IDs
The reason it doesnt work @joshuapinter for IDs is because if you look at the source:
case format when :db if respond_to?(:empty?) && self.empty? "null" else collect { |element| element.id }.join(",") # look at this line end else to_default_s end
It maps/collects the object ids and then joins them using a comma ; so in the case of 60 for instance :
60.object_id #=> 121
60.id #=> 121
