That did the trick. Thanks!
I copied your code into my Comment module and added:
def self.included(model)
register_commenting_model(model)
end
What about adding support for :limit. the only thing i can think of is
doing the following:
def self.comments_for_user(user)
commenting_models.inject([]) do |results, model|
results << model.all(:user => user, :order =>
[ :created_at.desc ], :limit => 10)
end.flatten.sort do |x,y|
x.created_at <=> y.created_at
end.first(10)
end
But that's kind of ugly since it would fetch rows that would then be
discarded.
cheers
