ok, still confused....
I've defined my parms like this...
def cart_params
# params.fetch(:cart, {})
params.require(:cart).permit(:user_id, :product_id )
end
Have this in my controller.
def add_to_cart
product_id = params['id']
user_id = session['user_id']
@cart = Cart.new(user_id, product_id)
end
Not sure what to put in the show page, to pass these values to the controller.
I've got a few rails books, and not one of them cover this.
