### 读取单个 Hero { #read-one-hero }

我们可以**读取**单个 `Hero`。

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[58:63] hl[60] *}

### 删除单个 Hero { #delete-a-hero }

我们也可以**删除**一个 `Hero`。

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[66:73] hl[71] *}

### 运行应用 { #run-the-app }

你可以运行这个应用：

<div class="termy">

```console

		}
		udMap = func(isMulti bool) map[string]string {
			m := map[string]string{
				crypto.MetaAlgorithm: crypto.InsecureSealAlgorithm,
				crypto.MetaMultipart: "1",
			}
			if !isMulti {
				delete(m, crypto.MetaMultipart)
			}
			return m
		}
	)

	// Single part object tests

	mkSPObj := func(s int64) ObjectInfo {
		return ObjectInfo{
			Size:        getEncSize(s),

	// remove this since we have removed support for this already.
	for k := range s[config.IdentityOpenIDSubSys] {
		for _, dk := range deprecatedKeys {
			kvs := s[config.IdentityOpenIDSubSys][k]
			kvs.Delete(dk)
			s[config.IdentityOpenIDSubSys][k] = kvs
		}
	}

	if err := s.CheckValidKeys(config.IdentityOpenIDSubSys, deprecatedKeys); err != nil {
		return c, err
	}

**요청** 본문을 선언하기 위해서 모든 강력함과 이점을 갖춘 [Pydantic](https://docs.pydantic.dev/) 모델을 사용합니다.

/// info | 정보

데이터를 보내기 위해, (좀 더 보편적인) `POST`, `PUT`, `DELETE` 혹은 `PATCH` 중에 하나를 사용하는 것이 좋습니다.

`GET` 요청에 본문을 담아 보내는 것은 명세서에 정의되지 않은 행동입니다. 그럼에도 불구하고, 이 방식은 아주 복잡한/극한의 사용 상황에서만 FastAPI에 의해 지원됩니다.

	default:
		var (
			selectColumns, restricted = stmt.SelectAndOmitColumns(true, false)
			_, updateTrackTime        = stmt.Get("gorm:update_track_time")
			isZero                    bool
		)
		stmt.Settings.Delete("gorm:update_track_time")

		values = clause.Values{Columns: make([]clause.Column, 0, len(stmt.Schema.DBNames))}

		for _, db := range stmt.Schema.DBNames {
