Before deploying, make sure you are logged in:

<div class="termy">

```console
$ fastapi login

You are logged in to FastAPI Cloud 🚀
```

</div>

Then deploy your app:

<div class="termy">

```console
$ fastapi deploy

Deploying to FastAPI Cloud...

✅ Deployment successful!

      // Read a boundary, skipping the remainder of the preceding part as necessary.
      if (partCount == 0 && source.rangeEquals(0L, dashDashBoundary)) {
        // This is the first part. Consume "--" followed by the boundary.
        source.skip(dashDashBoundary.size.toLong())
      } else {
        // This is a subsequent part or a preamble. Skip until "\r\n--" followed by the boundary.
        while (true) {

{* ../../docs_src/async_tests/main.py *}

文件 `test_main.py` 将包含针对 `main.py` 的测试，现在它可能看起来如下：

{* ../../docs_src/async_tests/test_main.py *}

## 运行测试

您可以通过以下方式照常运行测试：

<div class="termy">

```console
$ pytest

---> 100%
```

</div>

## 详细说明

这个标记 `@pytest.mark.anyio` 会告诉 pytest 该测试函数应该被异步调用：

{* ../../docs_src/async_tests/test_main.py hl[7] *}

/// tip

Mas podem ocorrer casos onde você deseja ser capaz de definir parâmetros na dependência, sem ter a necessidade de declarar diversas funções ou classes.

Vamos imaginar que queremos ter uma dependência que verifica se o parâmetro de consulta `q` possui um valor fixo.

Porém nós queremos poder parametrizar o conteúdo fixo.

## Uma instância "chamável" { #a-callable-instance }

## `SQLModel` 설치하기

먼저, [가상 환경](../virtual-environments.md){.internal-link target=_blank}을 생성하고 활성화한 다음, `sqlmodel`을 설치하세요:

<div class="termy">

```console
$ pip install sqlmodel
---> 100%
```

</div>

## 단일 모델로 애플리케이션 생성하기

우선 단일 **SQLModel** 모델을 사용하여 애플리케이션의 가장 간단한 첫 번째 버전을 생성해보겠습니다.

이후 **다중 모델**을 추가하여 보안과 유연성을 강화할 것입니다. 🤓

### 모델 생성하기

    @Min(-1)
    @Max(1000)
    @ValidateTypeFailure
    public Integer dayForCleanup;

    /**
     * Number of threads to use for crawling operations.
     * Higher values increase crawling speed but consume more resources.
     */
    @Required
    @Min(0)
    @Max(100)
    @ValidateTypeFailure
    public Integer crawlingThreadCount;

    /**
     * Enable or disable search query logging.

## 설치

<div class="termy">

```console
$ pip install fastapi

---> 100%
```

</div>

프로덕션을 위해 <a href="http://www.uvicorn.dev" class="external-link" target="_blank">Uvicorn</a> 또는 <a href="https://github.com/pgjones/hypercorn" class="external-link" target="_blank">Hypercorn</a>과 같은 ASGI 서버도 필요할 겁니다.

<div class="termy">

```console
$ pip install "uvicorn[standard]"

---> 100%

Переконайтеся, що Ви створили [віртуальне середовище](../virtual-environments.md){.internal-link target=_blank}, активували його та встановили пакет, наприклад:

```console
$ pip install python-multipart
```

Це необхідно, оскільки завантажені файли передаються у вигляді "форматованих даних форми".

///

## Імпорт `File`

Імпортуйте `File` та `UploadFile` з `fastapi`:

```
fastapi[standard]>=0.113.0,<0.114.0
pydantic>=2.7.0,<3.0.0
```

И обычно вы установите эти зависимости командой `pip`, например:

<div class="termy">

```console
$ pip install -r requirements.txt
---> 100%
Successfully installed fastapi pydantic
```

</div>

/// info | Информация

Stellen Sie sicher, dass Sie eine [virtuelle Umgebung](../virtual-environments.md){.internal-link target=_blank} erstellen, sie aktivieren und es dann installieren, zum Beispiel:

```console
$ pip install email-validator
```

oder mit:

```console
$ pip install "pydantic[email]"
```
