I have used following code for showing errors on a individual field  
level

ActionView::Base.field\_error\_proc = Proc.new do |html\_tag, instance|  
%{#{html\_tag}&nbsp;#{[instance.error\_message].flatten.first}}  
end

but it showing errors for label as well as for text field how to add  
modification so that it will show error only once?
