は、モデルのメソッドget_absolute_url()でreverse()を使用しますが、Djangoはエラー発生させます - ？のDoesNotExistをブログ/詳細/時/ ID = 23は、ないcorrect url - "/%3Fid=23"とurlpatternsを返すbecouseときI、パターンでこれを持っていませんcorrect url - "/?id=23"が必要です。なぜこれが起こり、それを修正するのですか？ブログマッチングクエリが存在しません。 （％3Fid =）

あなたの 'BlogDetailView'ビューの見た目を共有していません。 –
なぜあなたはそのようなURLを書いていますか？これはDjangoでのURLの記述方法ではありません。すべての '？：\？id ='を取り除いてください。 –
解決方法は、次のコードでget_absolute_url（）メソッドをオーバーライドし、urlパターンのGET形式の説明を削除することです。 def get_absolute_url（self）： return '{}？ {} '。形式（逆（ "blog_detail"）、urlencode（{'id'：self.pk}）） urlpatterns = [ url（詳細は$ '、BlogDetailView.as_view（）、name = "blog_detail"） 、 ] 解決策を提案http://vk.com/timofey.kukushkin – redwatcher
