Good morning, I'm doing a shopping cart and it has a function to list the products, and I return an array for later I list in my view but I do not know if it would be correct for me to do this in my class or inside a model and a controller, but what I need is to get the bank data I need to know if it's possible to do it directly in the class or I have to do with model and controller. thanks in advance to all the friends
