Count dupliate element
Tables: booking: show_id (belongs_to: show) show: name, venue_id (has_many :bookings belongs_to :venue) venue: location, capacity ( has_many : shows) NOW, I use this view, <h1>Listing venue rank</h1> <% @bookings.each do |booking| %> <tr> <td class="large box"> <%=h booking.show.venue.location %> <br /> </tr></table> it can get the booking venue list like that : Listing venue rank Location: www Location: www Location: weee Location: weee Location: www but I want 2 make this page like that: Listing venue rank Location: www 3 Location: weee 1 I want to count the dupliate locations and show the number. I think it will use distinct or count to modfy the controllers, but i do not figure out. please give me some sugguestion. class ShowsController < ApplicationController def index @shows = Show.find(:all, :order => "date") @venue = Venue.find(:all) class BookingsController < ApplicationController def index @bookings = Booking.find(:all, :order => "show_id, date") @venue = Venue.find(:all) @shows = Show.find(:all) class VenuesController < ApplicationController def index @venues = Venue.all -- Posted via http://www.ruby-forum.com/.
