It can't handle nested models very well. So, if the JSON body in the request is a JSON object that has inner fields that in turn are nested JSON objects, it cannot be properly documented and validated.

**FastAPI** を使用すると、深くネストされた任意のモデルを定義、検証、文書化、使用することができます（Pydanticのおかげです）。

## リストのフィールド { #list-fields }

属性をサブタイプとして定義することができます。例えば、Pythonの`list`:

{* ../../docs_src/body_nested_models/tutorial001_py310.py hl[12] *}

これにより、各項目の型は宣言されていませんが、`tags`はリストになります。

## タイプパラメータを持つリストのフィールド { #list-fields-with-type-parameter }

しかし、Pythonには内部の型、または「タイプパラメータ」を使ってリストを宣言するための特定の方法があります:

        GsaConfigException exception = new GsaConfigException("Serialization test");

        // Verify the exception is serializable (has serialVersionUID)
        assertNotNull(exception);
        // The serialVersionUID field exists and is accessible at compile time
        assertTrue(exception instanceof java.io.Serializable);
    }

    @Test
    public void test_stackTrace() {
        // Test that stack trace is properly preserved

      int expectedSize) {
    return new ObjectCountLinkedHashMap<K>(expectedSize);
  }

  private static final int ENDPOINT = -2;

  /*
   * The links field is not initialized directly in the constructor, but it's initialized by init(),
   * which the superconstructor calls.
   */

  /**

Поскольку `needy` является обязательным параметром, вам необходимо указать его в URL-адресе:

<parameters/> element. From these elements we need to make a component configuration for the MojoExecution. The actual DOM like structure we create is of type PlexusConfiguration and is the type we use with the ComponentConfigurator to initialize fields in a Plexus component. Typically this is done within Plexus with the configuration supplied with component configuration, but in Maven we take configuration values from the POM. So we have to use the ComponentConfigurator outside of Plexus in order...
