### `**user_in.dict()` 简介

#### Pydantic 的 `.dict()`

`user_in` 是类 `UserIn` 的 Pydantic 模型。

Pydantic 模型支持 `.dict()` 方法，能返回包含模型数据的**字典**。

因此，如果使用如下方式创建 Pydantic 对象 `user_in`：

```Python
user_in = UserIn(username="john", password="secret", email="******@****.***")
```

就能以如下方式调用：

```Python
user_dict = user_in.dict()
```

            }

            // Compute User IDs with Domain ID to get User SIDs
            // First extra is user if userId is empty
            if (!userId.isEmpty() && !userId.isBlank()) {
                this.userSid = new SID(domainId, userId);
            } else if (this.extraSids.length > 0) {
                this.userSid = this.extraSids[0];
            }

### Acerca de `**user_in.dict()` { #about-user-in-dict }

#### `.dict()` de Pydantic { #pydantics-dict }

`user_in` es un modelo Pydantic de la clase `UserIn`.

Los modelos Pydantic tienen un método `.dict()` que devuelve un `dict` con los datos del modelo.

Así que, si creamos un objeto Pydantic `user_in` como:

```Python

### `**user_in.dict()` 에 대하여

#### Pydantic의 `.dict()`

`user_in`은 Pydantic 모델 클래스인 `UserIn`입니다.

Pydantic 모델은 모델 데이터를 포함한 `dict`를 반환하는 `.dict()` 메서드를 제공합니다.

따라서, 다음과 같이 Pydantic 객체 `user_in`을 생성할 수 있습니다:

```Python
user_in = UserIn(username="john", password="secret", email="******@****.***")
```

그 다음, 다음과 같이 호출합니다:

from fastapi import FastAPI

app = FastAPI()


@app.get("/users/{user_id}/items/{item_id}")
async def read_user_item(
    user_id: int, item_id: str, q: str | None = None, short: bool = False
):
    item = {"item_id": item_id, "owner_id": user_id}
    if q:
        item.update({"q": q})
    if not short:
        item.update(
            {"description": "This is an amazing item that has a long description"}
        )
