The errors are both Cart.rb, line number 9:
def add_product(product)
-> @items << product
end
and
def add_to_cart
product = Product.find(params[:id])
@cart = find_cart
-> @cart.add_product(product)
end
Error:
You have a nil object when you didn't expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.<<
