這是我的書籍控制器,我在展示文件中的「刪除」如下所示。銷燬功能在RoR中不起作用
<%= link_to 'Delete', book,
data: { confirm: 'Are you sure?' }, method: :delete %>
我收到一個鏈接,但它不工作。我的代碼有什麼問題。提前致謝。
你的意思是「不工作」是什麼意思? 'BooksController#destroy'沒有被調用嗎? 'set_book'失敗了嗎? '@ book.destroy'是否失敗? JavaScript控制檯中的任何錯誤?服務器日誌中的任何內容? –
如果在那裏正確指定了所有內容,則需要調試'set_book'和'authenticate_user!'過濾器。 –
