Wes,
This may also a good candidate for using constraints, especially if
the scaffold is nested or embedded into another view. This
requires :medical_facility_categories to be in the column set for the
medical_facilities scaffold. Nested scaffolds do the filtering
automatically, but would only work for one category at a time (if
nesting below categories). For embedding, you can:
render :active_scaffold => 'medical_facilities', :constraints =>
{:medical_facility_categories => @medical_facility_category_ids}
to embed the scaffold in another view, and the scaffold will hide that
column and filter by the ids in the instance variable.
Even if you aren't nesting/embedding the scaffold, you can inject the
constraints into AS using a before_filter to get the same results:
active_scaffold_session_storage[:constraints] ||=
@medical_facility_category_ids
But Sergio's method is probably cleaner for a non-nested or embedded
scaffold...
Hope this helps,
Ryan
