`HTTPException` is a normal Python exception with additional data relevant for APIs.

Because it's a Python exception, you don't `return` it, you `raise` it.

* **데이터베이스 모델** 은 해시처리된 비밀번호를 가질 것입니다.

/// danger | 위험

절대 사용자의 비밀번호를 평문으로 저장하지 마세요. 항상 이후에 검증 가능한 "안전한 해시(secure hash)"로 저장하세요.

만약 이게 무엇인지 모르겠다면, [security chapters](security/simple-oauth2.md#password-hashing){.internal-link target=_blank}.에서 비밀번호 해시에 대해 배울 수 있습니다.

## 다중 모델

아래는 비밀번호 필드와 해당 필드가 사용되는 위치를 포함하여, 각 모델들이 어떤 형태를 가질 수 있는지 전반적인 예시입니다:

    implements List<E>, RandomAccess {

  ImmutableList() {}

  public static <E> Collector<E, ?, ImmutableList<E>> toImmutableList() {
    return CollectCollectors.toImmutableList();
  }

  // Casting to any type is safe because the list will never hold any elements.
  @SuppressWarnings("unchecked")
  public static <E> ImmutableList<E> of() {
    return (ImmutableList<E>) RegularImmutableList.EMPTY;
  }

    }
    @RetainedLocalRef Object localValue = valueField;
    if (localValue != null & notInstanceOfDelegatingToFuture(localValue)) {
      return getDoneValue(localValue);
    }
    // we delay calling nanoTime until we know we will need to either park or spin
    long endNanos = remainingNanos > 0 ? System.nanoTime() + remainingNanos : 0;
    long_wait_loop:
    if (remainingNanos >= SPIN_THRESHOLD_NANOS) {

    super(threadName);
    this.lockLikeObject = checkNotNull(lockLikeObject);
    start();
  }

  /*
   * TODO: b/318391980 - Once we test only under Java 20 and higher, avoid calling Thread.stop. As
   * of Java 20, it always throws an exception, and as of Java 26, the method does not even exist.
   * For now, we continue using it to clean up under older JDKs.
   *

 *         .nullsLast();
 * }
 *
 * Note that each chaining method returns a new ordering instance which is backed by the previous
 * instance, but has the chance to act on values <i>before</i> handing off to that backing instance.
 * As a result, it usually helps to read chained ordering expressions <i>backwards</i>. For example,
 * when {@code compare} is called on the above ordering:
 *
 * <ol>

* **出力モデル**はパスワードをもつべきではありません。
* **データベースモデル**はおそらくハッシュ化されたパスワードが必要になるでしょう。

## 複数のモデル

ここでは、パスワードフィールドをもつモデルがどのように見えるのか、また、どこで使われるのか、大まかなイメージを紹介します:

   * values.
   *
   * <p>Elements are copied from the argument collection as if by {@code collection.toArray()}.
   * Calling this method is as thread-safe as calling that method.
   *
   * @param collection a collection of {@code Character} objects
   * @return an array containing the same values as {@code collection}, in the same order, converted
