**FastAPI**'ı düzgün (ve önerilen) şekilde öğrenmek istiyorsanız [Öğretici - Kullanıcı Rehberi](../tutorial/index.md){.internal-link target=_blank}'ni bölüm bölüm okuyun.

- Get working code on a personal branch with tests before you submit a PR.
- OkHttp is a small and light dependency.  Don't introduce new dependencies or major new functionality.
- OkHttp targets the intersection of RFC correct *and* widely implemented.  Incorrect implementations that are very widely implemented e.g. a bug in Apache, Nginx, Google, Firefox should also be handled.

# Configure Swagger UI { #configure-swagger-ui }

You can configure some extra <a href="https://swagger.io/docs/open-source-tools/swagger-ui/usage/configuration/" class="external-link" target="_blank">Swagger UI parameters</a>.

To configure them, pass the `swagger_ui_parameters` argument when creating the `FastAPI()` app object or to the `get_swagger_ui_html()` function.

`swagger_ui_parameters` receives a dictionary with the configurations passed to Swagger UI directly.

    * Pydantic also allows representing it as a "ISO 8601 time diff encoding", <a href="https://docs.pydantic.dev/latest/concepts/serialization/#custom-serializers" class="external-link" target="_blank">see the docs for more info</a>.
* `frozenset`:
    * In requests and responses, treated the same as a `set`:
        * In requests, a list will be read, eliminating duplicates and converting it to a `set`.

**FastAPI**와 함께 원하는 어떤 템플릿 엔진도 사용할 수 있습니다.

일반적인 선택은 Jinja2로, Flask와 다른 도구에서도 사용됩니다.

설정을 쉽게 할 수 있는 유틸리티가 있으며, 이를 **FastAPI** 애플리케이션에서 직접 사용할 수 있습니다(Starlette 제공).

## 의존성 설치

가상 환경을 생성하고(virtual environment{.internal-link target=_blank}), 활성화한 후 jinja2를 설치해야 합니다:


<div class="termy">

```console
$ pip install jinja2

---> 100%
```

</div>

## 사용하기 `Jinja2Templates`

* `Jinja2Templates`를 가져옵니다.

在這裡，你將會看到**不同主題**的範例或「如何使用」的指南。

大多數這些想法都是**獨立**的，在大多數情況下，你只需要研究那些直接適用於**你的專案**的東西。

如果有些東西看起來很有趣且對你的專案很有用的話再去讀它，否則你可能可以跳過它們。

# The relation between column and classification.
#
# This property uses classification names of classificationDefinitionMap.
# The table name '$$ALL$$' means all tables are target.
# The table names and column names are treated as case insensitive.
#
# You don't need specify here about table classifications.
# Because table classifications are auto-deployed by relation information.
