collection_select question
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).
