On was deprecated and removed in Rails 4... I'm surprised that author would have even left something like that in a Rail 3.2 guide since it would have hindered future development... either way, to address your issue now you simply do `errors[:title]` to pull your error. If you are looking for it to return true or false then you should do `errors[:title].present?` or you can use `blank?` if you please. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
