I have a model_one that :has_many model_two-s, I would like to find the
ten model_one’s that have the most model_two’s. What is the best way to
Model_One.find(:all, :limit => 10, :include => :model_two, :order
=>“themost of model_two desc”)
or inorder for me to do this effeciently (I have thousands of
model_two-s) would i need to add a column to model_one, to keep track of
the number of model_two-s that model_one owns. Or is there some index i
can use? What is the best practice in this situation?
