Um einen Query-Parameter vom Typ `list` zu deklarieren, wie im Beispiel oben, müssen Sie explizit `Query` verwenden, sonst würde der Parameter als Requestbody interpretiert werden.

///

Die interaktive API-Dokumentation wird entsprechend aktualisiert und erlaubt jetzt mehrere Werte.

     * it returns a subclass of Joiner that overrides this method to tolerate null inputs.
     *
     * Unfortunately, we don't distinguish between these two cases in our public API: Joiner.on(...)
     * and Joiner.on(...).useForNull(...) both declare the same return type: plain Joiner. To ensure
     * that users *can* pass null arguments to Joiner, we annotate it as if it always tolerates null

この場合、`int`のキーと`float`の値を持つものであれば、どんな`dict`でも受け入れることができます:

{* ../../docs_src/body_nested_models/tutorial009.py hl[15] *}

/// tip | 豆知識

JSONはキーとして`str`しかサポートしていないことに注意してください。

しかしPydanticには自動データ変換機能があります。

これは、APIクライアントがキーとして文字列しか送信できなくても、それらの文字列に純粋な整数が含まれている限り、Pydanticが変換して検証することを意味します。

そして、`weights`として受け取る`dict`は、実際には`int`のキーと`float`の値を持つことになります。
