ruby - Customizing Devise error messages in Rails 3?

Question

I am using devise to handle authentication. Overall I like it, but I'd like to customize the error display a bit. Right now I've got the following in my view.

<div class="field <% if resource.errors[:email].present? %>error<% end %>">
  <%= f.label :email, "Email:" %><br />
  <% if resource.errors[:email].present? %>
    <ul>
      <% resource.errors[:email].each do |msg| %>
        <li><%= msg %></li>
      <% end %>
    </ul>
  <% end %>
  <%= f.text_field :email, :class => "text" %>
</div>

But when there is a problem with the email, the message displayed is as follows: is invalid. That's not very user friendly, but I can't find where this message is being set. It doesn't appear to be in devise.en.yml, but perhaps I'm overlooking something.

Any idea where I can customize the error messages?

Thanks!

You can configure the error messages in the locales file at: /config/locales/devise.en.yml

Which should have something like below code and which you can easily modify to your liking:

en:  
  errors:  
    messages:  
      not_found: "not found"  
      already_confirmed: "was already confirmed"  
      not_locked: "was not locked"  

  devise:  
    failure:  
      unauthenticated: 'You need to sign in or sign up before continuing.'  
      unconfirmed: 'You have to confirm your account before continuing.'  
      locked: 'Your account is locked.'  
      invalid: 'OH NOES! ERROR IN TEH EMAIL!'  
      invalid_token: 'Invalid authentication token.'  
      timeout: 'Your session expired, please sign in again to continue.'  
      inactive: 'Your account was not activated yet.'  
    sessions:  
      signed_in: 'Signed in successfully.'  
      signed_out: 'Signed out successfully.'
