Dump this method into your Ruby console to quickly print data in columns. This is helpful for e.g. comparing attributes of a set of Rails records.
def tp(objects, *method_names)
terminal_width = `tput cols`.to_i
cols = objects.count + 1 # Label column
col_width = (terminal_width / cols) - 1 # Column spacing
Array(method_names).map do |method_name|
cells = objects.map{ |o| o.send(method_name).inspect }
cells.unshift(method_name)
puts cells.map{ |cell| cell.to_s.ljust(col_width) }.join ' '
end
nil
end
Usage examples:
tp Video.where(key: '123'), :created_at, :updated_at, :published
tp [album1, album2], :title, :image_count
