Porting an Ubercart "Product Feature" to Commerce
I've started developing a module implementing a Product Feature for Ubercart 2.x.
The feature allows to link a user/client to a product: at the time you add the product to your cart, you can search and select a user (which is not the buyer but another user registered on the site) and link it to the product.
I implemented this as a Product Feature in Drupal6/Ubercart 2.x but the same concept doesn't seem to exist in Drupal7/Commerce
As I'm pretty new to Drupal 7 development, I'm wondering what is the best way to port the same functionality to Commerce.
I'm seeking from "design" best practices or standards.
Thanks for any suggestion.
