As a short elucidation, consider a stripped down version of the index
method in the GenericController -- all the models use this vanilla index
method from
GenericController.
def index
# index_setup is a routine that looks at session and params to
# return the proper order claause, condition clause, and a filtered
# list of ids for one or two special cases
order, cond, filtered = index_setup session, params
# user_rows is a user-defined rows per display table (we have widely
# varying monitor resolutions in use at the office)
rows = user_rows
# since I unfortunately named one model Filter, I have to direct to
# my filter class, not Rails' class
#
# but the views for all the models work in terms of @objects
# as the instance var for returned models
if params[:controller] == 'filters'
@objects = ::Filter.paginate :conditions => cond, :page =>
params[:page], :per_page => rows, :order => order
else
# constantize rules...
@objects =
params[:controller].singularize.camelcase.constantize.paginate
:conditions => cond, :page => params[:page], :per_page => rows, :order
=> order
end
end
but that should get you the idea.
