Your shopping_cart_item (singular) is probably a rails model and it
needs to start with a capital letter as it should be a ruby
constant.
When you define a model or any class in the normal way, you do
something like this
class ShoppingCartItem < ActiveRecord::Base
...
ShoppingCartItem is a ruby constant because it starts with capital (as
opposed to local variable or method name).
Also, you should probably use camel case instead of underscores for
constant names - that seems to be a convention but with rails it might
be a requirement (not completely sure as I've never done it that way).
You'd then refer to this class using class_name =>
'ShoppingCartItem' .
Your underlying table can stay as shopping_cart_items, of course.
You could probably dispense with class_name altogether if
"has_many :shopping_cart_items" refers to model ShoppingCartItem.
Rails will infer that for you.
