Dont use column name in errors

Hi Gabriel, I had the same problem

What I did was, copy the whole error_messages_for method from
ActiveRecordHelper
http://api.rubyonrails.org/classes/ActionView/Helpers/ActiveRecordHelper.html#M000568

and put it in my /app/helpers/application_helper.rb

then I just hacked the part that builds the header_message

actually my quibble was the object name, not the column names - but you
should be able to do what you like to it.

Maybe there is a better way though? seems this whole block of HTML
should be in a view in any case.
