You can ask for specific error messages.  I usually do that right
above the field on the form.  Say you have an item object with a
location property.

  <%= error_message_on :item, :location %>
  <%= f.label :location %>
  <%= f.text_field :location %>

That will add the location error message above it.  Only when there is
an error on the location property, will it show up.

You can also pull specific errors with the on method on the errors
collection.  Say you have a user, with an error on the name property.

u = User.new
u.valid?
u.errors.on(:name)
