HTTP_422_UNPROCESSABLE_ENTITYはdjango restフレームワークでは機能しません

Question

私のdjangoの残りのAPIからHTTP_422_UNPROCESSABLE_ENTITYを返そうとすると変なのですが、代わりに以下のエラーで500をスローしますが、同じコードは404を返します。

を有していないthis Pull Requestで説明したように、この戻りコードは、バージョン3.4.1にDjangoの残りのフレームワークに加えました。

このコードを使用できるようにバージョンを更新してください。以下のような新しいバージョンを

djangorestframework>=3.4.1 

または修正し、：：

djangorestframework==3.7.3 

djangorestframework==3.3.3 

は、あなたがそれを変更することができます：あなたのプロジェクトは、おそらくこのようなラインを持っているrequirements.txtファイルを、持っています
