在djangoviews.py中保存多個（onetoonefield）表單時出錯。請，需要正確的作業觀點或建議

我通過擴展抽象用戶模型創建了多個用于注冊的表單。我也將所有這些表格分別放在模板中。這是處理多個表單的正確方法嗎？行中面臨的問題 (vendordetail.save()) 非空欄位（onetoonefield 相關問題）。但我不知道如何為所有表單撰寫視圖。請幫我解決這個問題。

uj5u.com熱心網友回復：

你在哪里插入正確的vendoruser？這需要在呼叫 save() 之前填寫。

您需要執行以下操作：

vendordetail.instance.vendoruser = request.user

如果確實vendoruser是當前登錄的用戶，則您需要從其他地方獲取它。插入后，您可以呼叫：

vendordetail.save()

編輯：我錯過了您正在以另一種形式在同一頁面上創建用戶的情況。在這種情況下，您可以先保存您的用戶表單：

new_user = form.save()

模型表單的 save() 方法將回傳新物件，因此您可以稍后將其用于其他表單：

vendordetail.instance.vendoruser = new_user
