その追加情報はそのまま出力され、JSON Schemaに追加されます。

## `Field`の追加引数

後述する`Field`、`Path`、`Query`、`Body`などでは、任意の引数を関数に渡すことでJSON Schemaの追加情報を宣言することもできます:

{* ../../docs_src/schema_extra_example/tutorial002.py hl[4,10,11,12,13] *}

/// warning | 注意

これらの追加引数が渡されても、文書化のためのバリデーションは追加されず、注釈だけが追加されることを覚えておいてください。

///

## `Body`の追加引数

追加情報を`Field`に渡すのと同じように、`Path`、`Query`、`Body`などでも同じことができます。

## Forbid Extra Form Fields { #forbid-extra-form-fields }

In some special use cases (probably not very common), you might want to **restrict** the form fields to only those declared in the Pydantic model. And **forbid** any **extra** fields.

/// note

This is supported since FastAPI version `0.114.0`. 🤓

					case string:
						if field := db.Statement.Schema.LookUpField(column); field != nil {
							db.AddError(field.Set(db.Statement.Context, db.Statement.ReflectValue, eq.Value))
						}
					case clause.Column:

testImplementation("com.squareup.okhttp3:mockwebserver3-junit4:5.1.0")
```

Then in tests annotated `@org.junit.Test`, you may declare a field with the `@Rule` annotation:

```
@Rule public final MockWebServerRule serverRule = new MockWebServerRule();
```

The `serverRule` field has a `server` field. It is an instance of `MockWebServer`. That instance
will be shut down automatically after the test runs.

            // When
            var field = Handler.class.getField("DEFAULT_HTTPS_PORT");

            // Then
            assertTrue(Modifier.isPublic(field.getModifiers()));
            assertTrue(Modifier.isStatic(field.getModifiers()));
            assertTrue(Modifier.isFinal(field.getModifiers()));
            assertEquals(int.class, field.getType());
        }
    }

							t.Run(fieldStruct.Name, func(t *testing.T) {
