applications ClassRealm as the parent but the search order would be child first, and the parent ClassRealm can optionally choose to limit the searching to particular classes. The application ClassRealm, or parent ClassRealm, should only expose the API in the form of and application interface and model classes that may be required by plugins.

For debugging purposes we also need to keep track of what versions of artifacts are being used so that when we are debugging in the IDE we can find...

{* ../../docs_src/response_model/tutorial002.py hl[9,11] *}

そして、このモデルを使用して入力を宣言し、同じモデルを使って出力を宣言しています:

これで、ブラウザがパスワードを使ってユーザーを作成する際に、APIがレスポンスで同じパスワードを返すようになりました。

この場合、ユーザー自身がパスワードを送信しているので問題ないかもしれません。

しかし、同じモデルを別の*path operation*に使用すると、すべてのクライアントにユーザーのパスワードを送信してしまうことになります。

/// danger | 危険

ユーザーの平文のパスワードを保存したり、レスポンスで送信したりすることは絶対にしないでください。
