我嘗試了很多使用過濾器的方法，因為嘗試獲取單個物件但它仍然有效。當我從我的管理部分發帖時，一切正常，但是當使用表單從我的前端發帖時，它會創建帖子然后向我顯示物件不可迭代“注意：帖子創建得非常好”但我得到了可迭代的error 和 slug 不會像在后端管理部分那樣自動填充到前端。任何幫助都會非常有用，并使我的作業更快。讓我展示一些我的代碼

uj5u.com熱心網友回復：
查看您的模板代碼會很有幫助，但這里有一些我看到的問題。
第一，你的blogpost看法。當您執行 POST 請求時，在保存表單并設定成功訊息后，重定向到BlogDetail視圖。按照您的編碼方式，在保存表單后，它將再次呈現blogpost視圖，這次使用包含請求 POST 資料的表單。抬頭看redirect 這里。
其次，在您BlogList看來，您正在呼叫.values()您的查詢集posts。沒有看到您的模板代碼，我無法判斷這是否是故意的，但請確保您知道values()從查詢集中回傳的內容。您可能不想使用它。
第三，您的BlogDetail視圖不回傳任何內容，您需要render像其他視圖一樣使用例如回傳 HttpResponse 。
最后一點，它的通用約定是用小寫命名基于函式的視圖，用 _ 作為空格。CamelCase 保留用于基于類的視圖。
