Django 1.6 to 1.11 Admin.py migration

Question

古いDjango 1.6のadmin.pyコードをDjango 1.11に移植しようとしていますが、何らかの理由で1.11では動作しません。私はあなたに以下のコードを送っていますので、Django 1.11でおそらく動作しない古いコードの部分についていくつかの点を教えてください。どのようなヒントもありがとうございます。

それは単純なものであることが判明。ジャンゴ1.6で結構です

デフクエリセット（自己、リクエスト）があります。しかし、Djangoの1.11のための正しいオーバーライドする必要があります...
