i'm found the answer :

ActiveAdmin.register Role do
    form do |f|
        f.inputs "Role Details" do
          f.input :user_id
        end

        f.inputs "User Details" do 
          f.input :email, :input_html => { :value => f.object.user.email }      
        end

        f.actions
      end
end
