constraints.CreditCardNumber.message = {item}는 유효하지 않은 신용카드 번호입니다.
constraints.EAN.message = {item}는 유효하지 않은 {type} 바코드입니다.
constraints.Email.message = {item}는 올바른 이메일 주소가 아닙니다.
constraints.Length.message = {item}의 길이는 {min}에서 {max} 사이여야 합니다.
constraints.LuhnCheck.message = {value}의 Luhn Modulo 11 체크섬이 올바르지 않습니다.

And then, again, you get all the editor support:

Notice that this means "`one_person` is an **instance** of the class `Person`".

It doesn't mean "`one_person` is the **class** called `Person`".

         * AtomicReferenceFieldUpdaterAtomicHelper should always work on the JVM. (I mean, it
         * "should" always work on Android, too, but we know of a Samsung bug there :)) However, in
         * AggregateFutureStateFallbackAtomicHelperTest, we test what happens to AggregateFuture in

     * User controlled relocations.
     * This property is a comma separated list of entries with the syntax <code>GAV&gt;GAV</code>.
     * The first <code>GAV</code> can contain <code>*</code> for any elem (so <code>*:*:*</code> would mean ALL, something
     * you don't want). The second <code>GAV</code> is either fully specified, or also can contain <code>*</code>,
     * then it behaves as "ordinary relocation": the coordinate is preserved from relocated artifact.

Pero ahora sabes cómo funciona, para que puedas usar imports relativos en tus propias aplicaciones sin importar cuán complejas sean. 🤓

### Agregar algunos `tags`, `responses`, y `dependencies` personalizados

No estamos agregando el prefijo `/items` ni los `tags=["items"]` a cada *path operation* porque los hemos añadido al `APIRouter`.

Otra gran funcionalidad necesaria por las APIs es la validación de datos, asegurarse de que los datos sean válidos, dados ciertos parámetros. Por ejemplo, que algún campo sea un `int`, y no algún string aleatorio. Esto es especialmente útil para los datos entrantes.

constraints.CreditCardNumber.message = {item} は無効なクレジットカード番号です。
constraints.EAN.message = {item} は無効な {type} バーコードです。
constraints.Email.message = {item} は正しいメールアドレスではありません。
constraints.Length.message = {item} の長さは {min} から {max} の範囲にしてください。
constraints.LuhnCheck.message = {value} の Luhn Modulo 11 チェックサムが正しくありません。
