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| %\>

\<%= f.label :email %\> \<%= f.text\_field :email %\>

\<% f.fields\_for :member\_profile do |mp| %\>

\<%= mp.label :name %\> \<%= mp.text\_field :name %\>

\<% 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
