O servidor `fastapi dev` deverá recarregar automaticamente.

¿Recuerdas que te dije antes que `Annotated` puede usarse para agregar metadatos a tus parámetros en la [Introducción a Tipos de Python](../python-types.md#type-hints-with-metadata-annotations)?

Ahora es el momento de usarlo con FastAPI. 🚀

Teníamos esta anotación de tipo:

```Python
q: str | None = None
```

	if !regexp.MustCompile(`.*age.*=0.123457,`).MatchString(sql) {
		t.Errorf("Failed to generate sql, got %v", sql)
	}
}

func TestGroupConditions(t *testing.T) {
	type Pizza struct {
		ID   uint
		Name string
		Size string
	}
	dryRunDB := DB.Session(&gorm.Session{DryRun: true})

	stmt := dryRunDB.Where(
		DB.Where("pizza = ?", "pepperoni").Where(DB.Where("size = ?", "small").Or("size = ?", "medium")),

 *  Fix: Don't fail the call when the response code is ‘HTTP 102 Processing’ or
    ‘HTTP 103 Early Hints’.
 *  Fix: Read the response even if writing the request fails. This means you'll get a proper HTTP
    response even if the server rejects your request body.

    boolean supportsValuesHashCode = supportsValuesHashCode(map);
    if (supportsValuesHashCode) {
      int expectedEntrySetHash = 0;
      for (Entry<K, V> entry : entrySet) {
        assertTrue(map.containsKey(entry.getKey()));
        assertTrue(map.containsValue(entry.getValue()));
        int expectedHash =
            (entry.getKey() == null ? 0 : entry.getKey().hashCode())

## `q` 매개변수의 타입에 `Annotated` 사용하기 { #use-annotated-in-the-type-for-the-q-parameter }

이전에 [Python 타입 소개](../python-types.md#type-hints-with-metadata-annotations)에서 `Annotated`를 사용해 매개변수에 메타데이터를 추가할 수 있다고 말씀드린 것을 기억하시나요?

이제 FastAPI에서 사용할 차례입니다. 🚀

다음과 같은 타입 어노테이션이 있었습니다:

```Python
q: str | None = None
```

@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")
def read_item(item_id: int, q: str | None = None):
    return {"item_id": item_id, "q": q}


@app.put("/items/{item_id}")
def update_item(item_id: int, item: Item):
    return {"item_name": item.name, "item_id": item_id}
```

The `fastapi dev` server should reload automatically.
