爲什麼我的門票控制器創建操作失敗？

Question

下午好！

我似乎無法找到問題出現在我的門票上，我想也許再來看看它會有所幫助:)。此外，非常感謝您利用您的時間幫助我。

除了創建操作之外，我的故障單的所有頁面都能正常工作。在我點擊Create New Ticket後，轉到tickets_path即可正確工作。但是，它一直閃爍，無法提交票證。並且不會在表中創建記錄。

但是沒有錯誤，控制檯在下面的日誌中顯示窗體的參數。

你讓POST請求

時缺少user_id的屬性，這是因爲這行：

<td><%= f.label :user_id, "User Name" %></td> 

你的意思是寫

<td><%= f.hidden_field :user_id, value: current_user.id %></td>
