This is so simple it’s almost not even worth posting, but, oh well.

I needed to convert true or false fields from the database to image icons in my views on mutliple pages today, so I wrote this tiny helper and dropped it into my application_helper.rb file.

def true_false(test)
  if test == true
    icon = 'check.gif'
  else
    icon = 'x.gif'
  end
  image_tag(icon)
end

All it does is convert my tinyint fields from MySQL to image icons for a checkmark or an X and I can call it from anywhere since it’s in my application helper.

Cheers
