Hi Greg,

Rails by default use DB column name while displaying errors on UI. You can choose one of the following options to write custom validation errors

  1. User  plugin  [http://rubyforge.org/projects/custom-err-msg/](http://rubyforge.org/projects/custom-err-msg/)
  2. Check validation errors in validate method and use add_to_base for custom messages
  3. Override error_messages_for method –Haribhau

Put this in the model:

HUMAN_ATTRIBUTES = {:some_column => 'Column display name', :some_other_column => 'Another column display name'} def self.human_attribute_name(attr)   HUMAN_ATTRIBUTES[attr.to_sym] || super end

Obviously you want to replace my examples (:some_column, 'Column display name', etc.) with your column names and display versions of those names.
