Traditional Chinese version is at RailsFun . 正體中文版在 台灣Rails正體中文論壇RailsFun . First, in most cases, you should translate displayed attribute name by i18n.

This is my solution (thought a little bit ugly): put it in initializers/override_human_attribute_name.rb class ActiveRecord::Base def self.human_attribute_name(*attribute) super(*attribute) return "" end end And restart the rails server. By the way, in in Ruby Forum . There is a solution that override human_attribute_name too with a custom mapping HUMANIZED_COLUMNS hash. But the solution doesn't work straightly. It's because in ActiveModel::Errors have it's own count method. Which need some calculate in human_attribute_name. And if you don't provide it in your override. It will fail on calling model_instance.errors.count Tha
