    # Cookie 參數模型 { #cookie-parameter-models }
    
    如果你有一組彼此相關的「**Cookie**」,你可以建立一個「**Pydantic 模型**」來宣告它們。🍪
    
    這樣你就能在**多處**重複使用該模型,並且能一次性為所有參數宣告**驗證**與**中繼資料**。😎
    
    /// note | 注意
    
    自 FastAPI 版本 `0.115.0` 起支援。🤓

    ## Do not use Pydantic RootModels
    
    Do not use Pydantic `RootModel`, instead use regular type annotations with `Annotated` and Pydantic validation utilities.
    
    For example, for a list with validations you could do:
    
    ```python
    from typing import Annotated
    
    from fastapi import Body, FastAPI
    from pydantic import Field
    
    app = FastAPI()
    
    
    @app.post("/items/")

    * **Session and Cookie** support.
    * 100% test coverage.
    * 100% type annotated codebase.
    
    ## Pydantic features { #pydantic-features }
    
    **FastAPI** is fully compatible with (and based on) [**Pydantic**](https://docs.pydantic.dev/). So, any additional Pydantic code you have, will also work.

    # Body - 欄位 { #body-fields }
    
    就像你可以在「路徑操作函式 (path operation function)」的參數中用 `Query`、`Path` 和 `Body` 宣告額外的驗證與中繼資料一樣,你也可以在 Pydantic 模型中使用 Pydantic 的 `Field` 來宣告驗證與中繼資料。
    
    ## 匯入 `Field` { #import-field }
    
    首先,你需要匯入它:
    
    {* ../../docs_src/body_fields/tutorial001_an_py310.py hl[4] *}
    
    
    /// warning
    
    請注意,`Field` 是直接從 `pydantic` 匯入的,不像其他(如 `Query`、`Path`、`Body` 等)是從 `fastapi` 匯入。

    ### 關於 `**user_in.model_dump()` { #about-user-in-model-dump }
    
    #### Pydantic 的 `.model_dump()` { #pydantics-model-dump }
    
    `user_in` 是一個 `UserIn` 類別的 Pydantic 模型。
    
    Pydantic 模型有 `.model_dump()` 方法,會回傳包含該模型資料的 `dict`。
    
    因此,若我們建立一個 Pydantic 物件 `user_in` 如:
    
    ```Python
    user_in = UserIn(username="john", password="secret", email="******@****.***")
    ```

    This would allow you to **re-use the model** in **multiple places** and also to declare validations and metadata for all the parameters at once. 😎

    ///
    
    ### Pydantic and FastAPI `examples` { #pydantic-and-fastapi-examples }
    
    When you add `examples` inside a Pydantic model, using `schema_extra` or `Field(examples=["something"])` that example is added to the **JSON Schema** for that Pydantic model.
    
    And that **JSON Schema** of the Pydantic model is included in the **OpenAPI** of your API, and then it's used in the docs UI.

    * **CORS**、GZip、静的ファイル、ストリーミングレスポンス。

    ## Pydanticの機能 { #pydantic-features }
    
    **FastAPI** は [**Pydantic**](https://docs.pydantic.dev/) と完全に互換性があり(かつそれに基づいています)。そのため、手元の Pydantic の追加コードも動作します。

  9. docs/ko/docs/tutorial/encoder.md

    같은 방식으로 이 데이터베이스는 Pydantic 모델(속성이 있는 객체)을 받지 않고, `dict`만을 받습니다.
    
    이를 위해 `jsonable_encoder`를 사용할 수 있습니다.
    
    Pydantic 모델 같은 객체를 받고 JSON 호환 가능한 버전을 반환합니다:
    
    {* ../../docs_src/encoder/tutorial001_py310.py hl[4,21] *}
    
    이 예시에서는 Pydantic 모델을 `dict`로, `datetime`을 `str`로 변환합니다.
    
    이렇게 호출한 결과는 파이썬 표준인 [`json.dumps()`](https://docs.python.org/3/library/json.html#json.dumps)로 인코딩할 수 있습니다.

  10. docs/en/docs/tutorial/encoder.md

    The same way, this database wouldn't receive a Pydantic model (an object with attributes), only a `dict`.
    
    You can use `jsonable_encoder` for that.
    
    It receives an object, like a Pydantic model, and returns a JSON compatible version:
    
    {* ../../docs_src/encoder/tutorial001_py310.py hl[4,21] *}
    
    In this example, it would convert the Pydantic model to a `dict`, and the `datetime` to a `str`.
