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| %\>
