未創建的對象顯示在頁面上，並且重定向失敗

我嘗試了rails 3，剛開始一個新項目。以下是我輸入的全部內容。未創建的對象顯示在頁面上，並且重定向失敗

rails new todo 
cd todo 
bundle install 
rails generate scaffold Task done:boolean task:text created:date 
rake db:migrate 
rails server& 
firefox 0.0.0:3000/tasks&

在0.0.0:3000/tasks/new頁，我填寫了一些字段的值，單擊該按鈕來創建一個新task。它用空白頁重定向到0.0.0:3000/tasks。當我手動重新加載頁面時，即使應該只有一個，它也會顯示八個tasks。

當我再單擊show，edit或destroy，它說，對於例如爲：ActiveRecord::RecordNotFound in TasksController#showCouldn't find Task with ID=1。

當我重新加載到0.0.0:3000/tasks時，所有八個tasks仍然存在。

這有什麼問題？我的電腦上的導軌損壞了嗎？

重複x八次tasks/x不同從1到8：
