Thanks, I somehow got it fixed using observe_field. But, I'm not sure if its the right way in the scenario which is like: One combo box with name of location is on the top and when ever I change the location the combo box underneath will be updated with the areas within the location selected in the top combo box. With this bottom combo box there are few other text boxes as well where some input is given. At the bottom is a button "proceed to next area" when clicking which a new combo box with the similar text fields gonna add to the bottom of that updated combo box with the next area name. This keeps on until the end of the list is reached. Ok this is similar to what I'm trying to make:
https://www.epa.qld.gov.au/parks/iaparks/gds/IAGDS450.jsp Here's how got the first part sorted which is updating bottom combo with the top combo: IN CONTROLLER: -------------------------------------------------------------------------------- class UserController < ApplicationController def index end def update_campsites @campholder=[] id=params["walk_id"] @camps=Campsite.find_by_sql("select camp_location from campsites where walk_id="+id) for eachcamp in @camps @campholder << [eachcamp.camp_location, eachcamp.camp_location] end end end -------------------------------------------------------------------------------- IN MODEL: (loads great walks locations) -------------------------------------------------------------------------------- class GreatWalk < ActiveRecord::Base def self.getAvailableLocations @locations=GreatWalk.find(:all) @locationsholder=[] for eachlocation in @locations @locationsholder << [eachlocation.location,eachlocation.id] end @locationsholder end end -------------------------------------------------------------------------------- IN MODEL: (loads campsite locations) -------------------------------------------------------------------------------- class Campsite < ActiveRecord::Base belongs_to :great_walk belongs_to :fee has_many :customer_bookings def self.getAvailableCamps @campsholder=[] @camps=Campsite.find(:all) for camp in @camps @campsholder << [camp.camp_location, camp.id] end @campsholder end end -------------------------------------------------------------------------------- IN VIEW: (index.rhtml) -------------------------------------------------------------------------------- <h1>Great Walks Online Booking</h1> <form> <%= select(:selected, :id, GreatWalk.getAvailableLocations, {:prompt => 'Select a category'}, :id => :id_selected) %> <%= observe_field :id_selected, :url => {:action => :update_campsites}, :update => :campsites, :with => "walk_id" %> </form> <div id="campsites"> <form> <%=select "selected","camp","Please select location first:"%> </form> </div> -------------------------------------------------------------------------------- IN VIEW: (update_campsites.rhtml) -------------------------------------------------------------------------------- <%form_tag do %> <p> <label for="camp location">Campgroud</label> <%=select "selected","camp",@campholder%> </p> <p> <label for="arrival date">Arrival Date</label> <%=text_field_tag :name, params[:name]%> </p> <p> <label for="nights">Nights</label> <%=text_field_tag :nights, params[:nights]%> </p> <p> <label for="parents">Parents</label> <%=text_field_tag :parents, params[:parents]%> </p> <p> <label for="children">Children</label> <%=text_field_tag :children, params[:children]%> </p> <%=submit_tag "Calculate"%> <%end%> -------------------------------------------------------------------------------- PLZ any ideas on how can I achieve similar... thanks. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
