網友幫忙找到問題了,檢查用戶權限的自訂裝飾器出問題了 decorators.py :
修改過來就可以了。
T.T ,真是自己粗心大意。
python 程式碼縮排問題,我特意去查了,網友都建議縮排用4 個空格,用1 個tab 鍵代替風險太大,因為各家的編輯器對tab 鍵定義存在差異,很容易出問題。雖然說我這問題不是出在 tab 鍵上,之後我還是會注意到這個問題的。
不過我還有一問題,為什麼錯誤頁面拋出的是視圖函數View function 的問題,
而不會拋出裝飾器那邊的錯誤,例如( IndentationError ):
@admin_required → def permission_required(permission)
謝謝
