Rails 3 - Nested Resources Routing - One to One relationship - ruby-on-rails-3

Question

Having some trouble with some nested resources routing. What I'm trying to do is link to a user's profile page for editing purposes. In my view it is written as:
<%= link_to "Edit Profile", edit_user_profile_path(current_user) %>
Which errors out with:
No route matches {:action=>"edit", :controller=>"profiles", :user_id=>#<User id: 1, email: "EDITEDOUT", hashed_password: "EDITEDOUT", created_at: "2011-01-20 18:30:44", updated_at: "2011-01-20 18:30:44">}
In my routes.rb file, it looks like so:
resources :users do
resources :profiles, :controller => "profiles"
end
I checked my Rake routes, and it gave me this as a valid option:
edit_user_profile GET /users/:user_id/profiles/:id/edit(.:format) {:action=>"edit", :controller=>"profiles"}
Which I am able to manually navigate to. For good measures, here's proof of my controller:
class ProfilesController < ApplicationController
def edit
#user = current_user
#profile = current_user.profile
end
def update
#user = current_user
#profile = current_user.profile
respond_to do |format|
if #profile.update_attributes(params[:profile])
format.html { redirect_to(orders_path, :notice => "Your profile has been updated.") }
format.xml { head :ok }
else
format.html { render :action => "edit" }
format.xml { render :xml => #profile.errors, :status => :unprocessable_entity }
end
end
end
end
Anyway, I've been having some problem tracking this down. Any pointers would help. For my DB design Profiles belong to Users in a one-to-one relationship. I'm hoping it's just something newbish I'm not noticing a new set of eyes might help.

If you look closely at your route, you'll see that it expects both a :user_id and an :id. The latter, in this case, refers to the user profile.
In order to tell Rails that you want that particular profile, you'll have to specify both the user and the profile in your link, like this:
edit_user_profile_path(current_user, #profile)
Now, Rails will use the first argument (current_user) for the :user_id part of the route, and the second argument (#profile) for the :id.
