I have a shopping cart screen where I display my available item and all
it’s description info and then want to have the user enter a quantity.
I show all my item fields, e.g.
<%= @item.item_id %>
Then I have a field defined
<%= text_field ‘shopping_cart_item’ , ‘quantity’ %>
In my controller, how do I access this data?
I’ve tried many different ways, I just want to get this quantity first
to validate that it’s a number, that it’s less than the quantity
available, etc, then create a shopping cart record.
Help, I’ve spent a long time on this.
