"loc": [
        "path",
        "item_id"
      ],
      "msg": "Input should be a valid integer, unable to parse string as an integer",
      "input": "foo",
      "url": "https://errors.pydantic.dev/2.1/v/int_parsing"
    }
  ]
}
```

because the path parameter `item_id` had a value of `"foo"`, which is not an `int`.

## Modelos de Pydantic

<a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> es una library de Python para llevar a cabo validación de datos.

Tú declaras la "forma" de los datos mediante clases con atributos.

Cada atributo tiene un tipo.

# shellcheck disable=SC1001
LATEST_DISTROLESS_SHA256=$(crane digest cgr.dev/chainguard/static | awk -F\: '{print $2}')

## Pydantic modelleri

<a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> veri doğrulaması yapmak için bir Python kütüphanesidir.

Verilerin "biçimini" niteliklere sahip sınıflar olarak düzenlersiniz.

Ve her niteliğin bir türü vardır.

```

You can receive and send binary, text, and JSON data.

## Try it

If your file is named `main.py`, run your application with:

<div class="termy">

```console
$ fastapi dev main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

它也被設計成可作為未來的參考，讓你隨時回來查看所需的內容。

## 運行程式碼

所有程式碼區塊都可以直接複製和使用（它們實際上是經過測試的 Python 檔案）。

要運行任何範例，請將程式碼複製到 `main.py` 檔案，並使用以下命令啟動 `fastapi dev`：

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev <u style="text-decoration-style:single">main.py</u>
<font color="#3465A4">INFO    </font> Using path <font color="#3465A4">main.py</font>

		# remove mc source.
		purge "${MC_BUILD_DIR}"
	fi

	"${MINIO[@]}" --address ":$start_port" "${WORK_DIR}/disk{1...4}" >"${WORK_DIR}/server1.log" 2>&1 &
	pid=$!
	disown $pid
	sleep 5

	if ! ps -p ${pid} 1>&2 >/dev/null; then
		echo "server1 log:"
		cat "${WORK_DIR}/server1.log"
		echo "FAILED"
		purge "$WORK_DIR"
		exit 1
	fi

	"${PWD}/mc" mb --with-versioning minio/bucket

	for i in $(seq 1 4); do

И все это, чтобы все пользователи могли получать наилучший опыт разработки.

## Зависимости

Протестировав несколько вариантов, я решил, что в качестве основы буду использовать <a href="https://docs.pydantic.dev/" class="external-link" target="_blank">**Pydantic**</a> и его преимущества.
