Hi,

I’m still adjusting to Ruby on Rails and the MVC model. But I wanted  
to query the group on what the best design is – i.e. how many  
controllers should I have for the following. A customer will register  
on our site to order a product. After registration, or if they leave  
and decide to log in again, they can place their orders through a pre-  
built order form. After placing the order, they see a thank you  
screen and receive a confirmation email.

What is the best number of controllers (and which ones) should I  
create for this?

Thanks, - Dave

I would think you’ll need 3.

Customers  
Products  
Orders

Each customer has\_many orders, and each order has\_many products. But  
you also might need something for payments also, depending on how you  
process them.
