Rails - Aug 2006 - 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)
