 * ## Force a Cache Response
 *
 * Sometimes you'll want to show resources if they are available immediately, but not otherwise.
 * This can be used so your application can show *something* while waiting for the latest data to be
 * downloaded. To restrict a request to locally-cached resources, add the `only-if-cached`
 * directive:
 *
 * ```java
 * Request request = new Request.Builder()

		if getRequestAuthType(r) == authTypeAnonymous {
			// As per "Permission" section in
			// https://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectGET.html
			// If the object you request does not exist,
			// the error Amazon S3 returns depends on
			// whether you also have the s3:ListBucket
			// permission.

	Object            string        `json:"object" msg:"ob"`             // Last rebalanced object

		return h.healBucket(objAPI, h.bucket, false)
	}

	buckets, err := objAPI.ListBuckets(h.ctx, BucketOptions{})
	if err != nil {
		return errFnHealFromAPIErr(h.ctx, err)
	}

	// Heal latest buckets first.
	sort.Slice(buckets, func(i, j int) bool {
		return buckets[i].Created.After(buckets[j].Created)
	})

여기서는 애플리케이션 시작 이벤트 시 테이블을 생성합니다.

프로덕션 환경에서는 애플리케이션을 시작하기 전에 실행되는 마이그레이션 스크립트를 사용할 가능성이 높습니다. 🤓

/// tip | 팁

SQLModel은 Alembic을 감싸는 마이그레이션 유틸리티를 제공할 예정입니다. 하지만 현재 <a href="https://alembic.sqlalchemy.org/en/latest/" class="external-link" target="_blank">Alembic</a>을 직접 사용할 수 있습니다.

///

### Hero 생성하기

각 SQLModel 모델은 Pydantic 모델이기도 하므로, Pydantic 모델을 사용할 수 있는 **타입 어노테이**션에서 동일하게 사용할 수 있습니다.

///

If you are using `pip` to install packages (it comes by default with Python), you should **upgrade** it to the latest version.

Many exotic errors while installing a package are solved by just upgrading `pip` first.

/// tip

You would normally do this **once**, right after you create the virtual environment.
