#### 用另一个模型的内容生成 Pydantic 模型 { #a-pydantic-model-from-the-contents-of-another }

上例中 ，从 `user_in.model_dump()` 中得到了 `user_dict`，下面的代码：

```Python
user_dict = user_in.model_dump()
UserInDB(**user_dict)
```

等效于：

```Python
UserInDB(**user_in.model_dump())
```

Aber in der Praxis werden Sie mit den integrierten [Sicherheits-Werkzeugen](security/index.md) bessere Ergebnisse erzielen.

## Ein weiteres Modul mit `APIRouter` { #another-module-with-apirouter }

Nehmen wir an, Sie haben im Modul unter `app/routers/items.py` auch die Endpunkte, die für die Verarbeitung von Artikeln („Items“) aus Ihrer Anwendung vorgesehen sind.

    }

    @Override
    public CharMatcher and(CharMatcher other) {
      return other.matches(match) ? super.and(other) : other;
    }

    @Override
    public CharMatcher or(CharMatcher other) {
      return other.matches(match) ? any() : this;

  /**
   * Ensures that {@code index} specifies a valid <i>element</i> in an array, list or string of size

    password = user_dict["password"],
    email = user_dict["email"],
    full_name = user_dict["full_name"],

```

#### Pydantic-модель из содержимого другой { #a-pydantic-model-from-the-contents-of-another }

Как в примере выше мы получили `user_dict` из `user_in.model_dump()`, этот код:

```Python
user_dict = user_in.model_dump()
UserInDB(**user_dict)
```

будет равнозначен такому:

```Python

    password = user_dict["password"],
    email = user_dict["email"],
    full_name = user_dict["full_name"],
)
```

#### Um modelo Pydantic a partir do conteúdo de outro { #a-pydantic-model-from-the-contents-of-another }

Como no exemplo acima, obtivemos o `user_dict` a partir do `user_in.model_dump()`, este código:

```Python
user_dict = user_in.model_dump()
UserInDB(**user_dict)
```

seria equivalente a:

## 另一個帶有 `APIRouter` 的模組 { #another-module-with-apirouter }

假設你還有一個模組 `app/routers/items.py`，專門處理應用程式中的「items」。

你有以下路徑操作：

* `/items/`
* `/items/{item_id}`

其結構與 `app/routers/users.py` 相同。

但我們想要更聰明地簡化一些程式碼。
