Hi,

I’m new to rails and I’m following along the depot sample application  
in Agile Web D. with Rails

> From what I understand I should not need to restart the server after

I got stuck on the part where you need to update the add\_product  
function in cart.rb in order for it to not insert the same product  
twice but just increase the quantity.

For about an hour I was wondering why nothing changed and I tried all  
sorts of stuff until I decided to give restarting the server a try. And  
that did the trick  
But isn’t that unnecessarry when running in dev mode?

thanks  
Marc

In development mode you don’t need to restart the server when you  
make changes to your controllers or views. But you do need to  
restart the server when you change a model.

in model , make sure you  
include Reloadable or is  
subclass of ActiveRecord::Base(which include Reloadable).
