Rails - Feb 2008 - Why isn't validation kicking in and how can I make it so?

Hi,

I have a model, ec_order, which has multiple ec_line_items.  You start
a "new" order through the OrderController ...

class OrderController < ApplicationController
        def new
            if logged_in?
                @user = User.find(session[:user_id])
                @ec_order = EcOrder.new
                3.times { @ec_order.ec_line_items.build }
            else
                flash[:notice] = "You must be logged in to access this
page."
                redirect_to :controller => "register", :action
=>
"start"
            end
        end

        def summary
                @ec_order = EcOrder.new(params[:ec_order])
                session[:ec_order] = @ec_order
        end

...
end

Here''s the ec_line_item model:

class EcLineItem < ActiveRecord::Base
        belongs_to :ec_order

        validates_numericality_of :prescription_number, :integer_only
=> true
end


In the form on the "new" view, you submit to the "summary"
action.
How can I detect if the ec_line_item objects are valid or not and
reroute back to the "new" action?  Thanks, - Dave


PS - If it''s useful, here''s the app/views/order/new.rhtml
file:

===================Begin new.rhtml file============================<%
form_for :ec_order, :url => ''summary'' do |f| %>

        <tr>

        </tr>
        <%= f.hidden_field :ship_first_name, :value =>
@user.ship_to_first_name %>

                                <%= render :partial =>
''ec_line_item'', :collection => @ec_order.ec_line_items
%>
                                </div>
                                <%= add_prescription_link "Add a

                        </td></tr>
                </table>
        </td></tr>
        <tr><td align="center"><%=
submit_tag("Submit Form") %></td></
tr>
</table>
<% end %>
