In your form view change your current code

      <%@object.errors.full_messages.each do |msg| %>
        <li><%= msg %></li>
      <% end %>

With this

      <%@object.errors.messages.values.each do |msg| %>
        <%msg.each do  |m| %>
          <li><%= m %></li>
        <%end %>
      <% end %>

If you don't want to use a double loop: `<% @object.errors.messages.values.flatten.each do |error| %>
<%= error %>

This worked for us (Rails 4):

<% resource.errors.each do |attr,msg| %>
    <li><%= msg %></li>
<% end %>

Using Rails 4.0.2, this removed the error message text and left only the bullet. – Deborah Dec 08 '13 at 04:01

This worked for me in Rails 4 (haml):

%ul
  - @some_object.errors.messages.each do |message|
    %li= message[1][0]

  class Errors
    def full_messages
      map { |attribute, message|
        message
      }
    end
  end
end

You can use the following Gem

You can use a '^' character at the start of the message value. And it will only show the characters after this.

 validates_presence_of :title, :message => "^no title"

You can use the following Gem also

If you change the label of the element it will effect the error message label. So if you change it to a blank string it will render just the message:

-# reviews/_form.html.haml
= form_for review do |form|
  = form.label :rating, (review.errors[:rating] ? "" : "Rate this Item" )
