Hi Frederick,
Thanks for your additional help with a simpler solution. I tried to
replace my select_tag approach with the f.select approach:
<%= f.select :vendor, @current_vendors %>
<%# = select_tag "expense[vendor]",
options_for_select(@current_vendors) %>
1. The f.select :vendor provided the drop-down control, but
selecting an item did not populate the vendor text control, as the
former solution did, some I'm sure I misunderstand your intent.
2. I haven't found documentation for the precise thing you
recommended, but I'm hopeful I'll have some luck with
http://api.rubyonrails.org/classes/ActionView/Helpers/FormHelper.html
and/or http://guides.rubyonrails.org/form_helpers.html when I get time
for careful study.
Best wishes,
Richard
