Ah, sorry. I've now deleted everything from my Recommendations
controller:
class Recommendations < Application
# provides :xml, :yaml, :js
controlling :recommendations do |r|
r.belongs_to :user
end
end # Recommendations
However, that still lists all the recommendations in both cases. I
have this in my index.html.erb:
<div>
<ul>
<%= partial :recommendation, :as => :recommendation, :with =>
@recommendations %>
</ul>
</div>
And the partial:
<%= tag(:li, "#{recommendation.user.name} recommends #
{recommendation.recommendee.name}") %>
