Ruby on Rails: errors.add_to_base vs. errors.add

Question

I have read that errors.add_to_base should be used for errors associated with the object and not a specific attribute. I am having trouble conceptualizing what this means. Cou

Answer 1

It's worth noting (since this shows up in the search engines, which is how I found it) that this is deprecated. The Rails 3 way of doing it is:

errors[:base] << "Error message"    

or

errors.add(:base, "Error message")
