ruby on rails - How to Show Error Messages Next to Field

Question

I have a form with input fields/labels etc. How do I get the error message to show up next to the field? instead of clumped together at the top?

I am using devise, rails 3

I have this at the top of my form:

 = form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f|
- if resource.errors.any?
  #errorExplanation
    %h2
      = pluralize(resource.errors.count, "error")
      prevented this user from being saved:
    %ul
      - resource.errors.full_messages.each do |msg|
        %li
          = msg

Answer 1

You can use this

- if @resource.errors[:field_name]
  ...
