Re-using a Listing screen form

How do I display subsets of records on a Listing page (that lists in
grid form table records)? In particular, when displaying the Listing
page, it would be nice to allow the user to display a subset of the
records, for example, by filtering.

For example, I have the following Controller Listing and Filtering
actions:

def list
@eng_sense_pages, @eng_senses = paginate :eng_senses, :per_page =>
10
end

def filter_by_synset_offset
@eng_senses =
EngSense.find_by_synset_offset(params[:synset_offset])
if @eng_senses
redirect_to :action => ‘list’
else
flash[:notice] = “Unable to find English synset offset:
#{:synset_offset}”
end
end

However, the resulting display shows the full table, not the filtered
subset. Is this because of the directive: @ng_senses = paginate
:eng_senses, in the definition of the lists?

How does one display a subset of the table records in a grid display?

Thanks!

maybe you can use the :condition in the paginate, as I do when searching
:

conditions = [“synset_offset LIKE ?”, “%#{@params[:synset_offset]}%”]
unless @params[:synset_offset].nil?
@ eng_sense_pages, @ eng_senses = paginate(:eng_senses,
:conditions => conditions, :per_page => 10)
