If you're simply wanting to get the csv database yourself from the console you can do so in a few lines

tags = [Model.column_names]
rows = tags + Model.all.map(&:attributes).map(&:to_a).map { |m| m.inject([]) { |data, pair| data << pair.last } }
File.open("ss.csv", "w") {|f| f.write(rows.inject([]) { |csv, row|  csv << CSV.generate_line(row) }.join(""))}
