Rails Todo Project

I'm going through the rails todo project. Working on deleting todo items... Here's my todo_items controller where I'm deleting...

def destroy @todo_list = @todo_list.todo_items.find(params[:id]) if @todo_item.destroy flash[:success] = "Todo list item was deleted" else flash[:error] = "Todo list item could not be deleted" end redirect_to todo_list_todo_items_path end

I keep getting an error for undefined method 'destroy' for nil:NilClass

I can't figure it out. I check the videos again... and stackoverflow and can't seem to figure out why this isn't working.

Any ideas?

Thanks!

Figures... I find the issue right after posting. Always happens that way right?
