has_one nil from Devise

I'm using namespace with Devise and i can't get the object ptofile in view
to render.

class Freelances::ProfilesController < ApplicationController

  before_filter :authenticate_freelance!

  def show
    respond_with = current_freelance.profile
  end

end

show.html.erb

<%=render @profile %>
<%=link_to 'edit', edit_freelances_profiles_path(@profile)%>
<%=link_to 'remove', :confirm => 'Você tem certeza?', :method => :delete %>

error

'nil' is not an ActiveModel-compatible object that returns a valid partial
path.

Extracted source (around line #1):

1: <%=render @profile %>

That means @profile is nil.
