Rails - Mar 2005 - FormOptionHelper

Hi All,

I''m a newbie.. and I''m trying to add a series of selects to
the bottom of a
scaffolded "list" to act as filters.. (so: to filter for elements with
field
YADA equal to WHATEVER)..

I''d like to use select from FormOptionsHelper, but the docs and all
examples
seem to imply that it needs to set a value in an existing object.. in this 
case I really just want the controller to have a series of member variables 
that are the filters (ie: @submitted_filter). 

The code below I added to the list.rhtml and of coarse.. it doesn''t
work
because it''s trying to set to_s= to the selected value I think..

<%= start_form_tag :action => ''list'' %>
<p><label>Submitted</label><%= select
''submitted_filter'', ''to_s'',
SubmissionsController.SubmittedFilterOptions %>
<input type="submit" value="Filter" /></p>
<%= end_form_tag %>

and I added the following to the list method in the controller:
@submitted_filter = @params[''submitted_filter''] ||
''''

Am I going about this entirely wrong? Thanks in advance for any help!!

I managed to get this working by using an OStruct and having all the filters 
be dynamic attributes of it.. but it''s odd that there isn''t a
way to use the
FormOptionsHelper without it expected an object to set the value on (rather 
than being passed the value itself as an option).
