Rails - May 2009 - Nested Models & Error Validation

I have two models: User and MemberProfile

class MemberProfile < ActiveRecord::Base
  belongs_to :user
  validates_presence_of :name
 #...
end

class User < ActiveRecord::Base
  has_one :member_profile
  validates_presence_of :email
  accepts_nested_attributes_for :member_profile
  #...
end

My view looks like:

<%= error_messages_for :user %>
<% form_for :user, :url => users_path do |f| %>
<p><%= f.label :email %>
<%= f.text_field :email %></p>
<% f.fields_for :member_profile do |mp| %>
<p><%= mp.label :name %>
<%= mp.text_field :name %>
</p>

<% end %>
<% end %>

The error validations are working correctly. It is checking for both
email and name on both objects. The error list is correctly populating
the error_messages_for call. The two problems I''m having are:
1. I''d like the errors for the MemberProfile object to be displayed as
"Name can''t be..." instead of "Member profile name
can''t be..." in
div#errorExplanation
2. The MemberProfile fields are not receiving the div.fieldWithErrors

Is there a way to deal with these two issues?

Thanks
