Vinay - you nailed it. Many thanks.
I ended up with my controller like this.... #=========== class WelcomeController < ApplicationController def index # finding all the locations for the drop down @locations = Location.all if params[:commit] == "go" && params[:location][:id].to_i >= 1 # location is set AND it's not a blank location id so find the teachers in the location @location = Location.find(params[:location][:id]) @teachers = @location.teachers else # no form submitted so find just find all teachers @teachers = Teacher.all end end end #========= Here's my view code.. <% title "Welcome" %> <p> Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum. </p> <hr> <% form_tag do %> <%= select("location", "id", Location.all.collect {|l| [ l.name, l.id ]}, {:include_blank => true}) %> <%= submit_tag "go" %> <% end -%> <hr> <% if @teachers %> <% for teacher in @teachers %> <%= link_to [teacher.first_name + ' ' + teacher.last_name], teacher %><br> <%= teacher.email %><br> Location: <%= teacher.location.name %><br> Languages: <% for language in teacher.languages %> <%= language.name %> <% end %> <hr> <% end %> <% end %> #============ Works great. I'm interested to see any critique of this code? all comments appreciated. Is there a better way to handle the && params[:location][:id].to_i >= 1 it's the way I thought to do it? Many thanks to all for the comments here - very useful. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
