：select在Rails 2.3中使用：include或类似的activerecord功能

Question

Does anyone have an elegant way of doing an activerecord call containing a :select AND an :include statement? I have seen a lot of really old information about getting this working in rails 2.3 and I also know that it is functional in rails 3 but unfortunately not in activerecord core as of 2.3. I am using rails 2.3.4 ruby 1.8.7

Answer 1

Parent.find(:all, :select => "foo, bar", :include => :child)
