### Ler Um Hero com `HeroPublic` { #read-one-hero-with-heropublic }

Podemos **ler** um único herói:

{* ../../docs_src/sql_databases/tutorial002_an_py310.py ln[75:80] hl[77] *}

### Atualizar um Hero com `HeroUpdate` { #update-a-hero-with-heroupdate }

Podemos **atualizar um hero**. Para isso, usamos uma operação HTTP `PATCH`.

### Read One Hero with `HeroPublic` { #read-one-hero-with-heropublic }

We can **read** a single hero:

{* ../../docs_src/sql_databases/tutorial002_an_py310.py ln[75:80] hl[77] *}

### Update a Hero with `HeroUpdate` { #update-a-hero-with-heroupdate }

We can **update a hero**. For this we use an HTTP `PATCH` operation.

### Einen einzelnen Helden mit `HeroPublic` lesen { #read-one-hero-with-heropublic }

Wir können einen einzelnen Helden **lesen**:

{* ../../docs_src/sql_databases/tutorial002_an_py310.py ln[75:80] hl[77] *}

### Einen Helden mit `HeroUpdate` aktualisieren { #update-a-hero-with-heroupdate }

Wir können einen Helden **aktualisieren**. Dafür verwenden wir eine HTTP-`PATCH`-Operation.

### 用 `HeroPublic` 读取单个 Hero

我们可以**读取**单个 `hero` 。

{* ../../docs_src/sql_databases/tutorial002_an_py310.py ln[75:80] hl[77] *}

### 用 `HeroUpdate` 更新单个 Hero

我们可以**更新**单个 `hero` 。为此，我们会使用 HTTP 的 `PATCH` 操作。

在代码中，我们会得到一个 `dict` ，其中包含客户端发送的所有数据，**只有客户端发送的数据**，并排除了任何一个仅仅作为默认值存在的值。为此，我们使用 `exclude_unset=True` 。这是最主要的技巧。🪄

{* ../../docs_src/sql_databases/tutorial002_an_py310.py ln[65:72] hl[65] *}

### `HeroPublic`으로 단일 Hero 조회하기

단일 hero을 **조회**할 수도 있습니다:

{* ../../docs_src/sql_databases/tutorial002_an_py310.py ln[75:80] hl[77] *}

### `HeroUpdate`로 Hero 수정하기

**hero를 수정**할 수도 있습니다. 이를 위해 HTTP `PATCH` 작업을 사용합니다.
