How do I specify which option should be initially selected when using the collection_select command? I''ve tried: collection_select(:selectionfilter, :producer_id, Producer.find(:all), :id, :name, {:include_blank => true, :selected_value => @initial_selection}) However it doesn''t return the desired results (the option with the value of @initial_selection selected).
