thanks Kevin. in case anyone else has the same kind of problem, where
you've got an index page dated items, and want to filter past, future
etc.
my solution is as follows...
in my index view i've added a filter (using your filter-menu-without-
no-option from another thread here)
<div class="filter">
Display by date: <filter-menu-without-no-option param-
name="range" options="&@range"/>
</div>
in the model (possibly overkill, taken directly from railscasts...)
named_scope :future, lambda { |*args |{:conditions => [ "date > ?",
(args.first || Date.today) ] }}
named_scope :overdue, lambda { |*args |{:conditions => [ "date < ?",
(args.first || Date.today) ] }}
named_scope :today, lambda { |*args |{:conditions => [ "date = ?",
(args.first || Date.today) ] }}
then in the controller i have an index method with...
@range = ["All","overdue","today","future"]
if params[:range] == "future"
hobo_index Todo.future.apply_scopes(.....
else if params[:range] == "overdue"
hobo_index Todo.overdue.apply_scopes(:search =>
[params[:search], :name],
else if params[:range] == "today"
hobo_index Todo.today.apply_scopes(:search =>
[params[:search], :name],
and so on. i expect there's a tider solution than my chain of ifs, but
it works for me :-)
thanks again
Paul
