controller logic not working

rubyonrails-talk

So I've written this code in my controller and it doesn't seem to process my records and I don't know why.

error = nil @my_cart = @user.shopping_cart @my_cart_items = @user.shopping_cart.shopping_cart_items for shopping_cart_item in @my_cart_items    if @quantity > 0       ....do stuff    end

end

Is this valid?

Hello--

So I've written this code in my controller and it doesn't seem to process my records and I don't know why.

error = nil @my_cart = @user.shopping_cart @my_cart_items = @user.shopping_cart.shopping_cart_items for shopping_cart_item in @my_cart_items   if @quantity > 0      ....do stuff   end

end

Is this valid? --

No. This doesn't look like it should work. I'd really recommend reading up on Ruby a bit. @my_cart_items would appear to be a collection (an array). Using "for" you are iterating over that list but you are not using the individual item yielded by the iterator. So, perhaps what you wanted was:

for shopping_cart_item in @my_cart_items do |item|    unless item.quantity.zero?      # do stuff...    end end
