how to make select element 'remember' previous value

so in a rails app i have this collection_select element as part of a form. When creating a story object it works fine but on subsequent edits the select element never remembers the previous value, users rarely change the edition during an edit but ofter forget to check it. So how to i make it remember its value when editing?



<%= collection_select(:story, :edition_id, Edition.all, :id, :name, {:include_blank => '-select story type-'} ) %>

Is the edition_id being stored in the database correctly?
I have a similar collection select that works OK:

<%= collection_select 'sub_category', 'parent_id', @categories, :id, :description, {:include_blank => true} %>

oh yeah, i was storing edition_id as a string, which should of course be an integer. Works now, thanks.
