# Modelos de Formulario

Puedes usar **modelos de Pydantic** para declarar **campos de formulario** en FastAPI.

/// info | Información

Para usar formularios, primero instala <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

Asegúrate de crear un [entorno virtual](../virtual-environments.md){.internal-link target=_blank}, activarlo, y luego instalarlo, por ejemplo:

```console

import java.util.Properties;

import org.apache.maven.api.Constants;
import org.apache.maven.api.annotations.Nullable;

/**
 * Centralized class for Maven Core feature information.
 * Features configured are supposed to be final in a given maven session.
 *
 * @since 4.0.0
 */
public final class Features {

    private Features() {}

    /**
     * Check if the personality is "maven3".
     */

import org.codelibs.fess.util.ResourceUtil;

/**
 * Helper class for managing theme installation and uninstallation.
 * Handles the extraction and deployment of theme files from JAR artifacts.
 */
public class ThemeHelper {
    private static final Logger logger = LogManager.getLogger(ThemeHelper.class);

    }

    /** Role name for admin search request operations */
    public static final String ROLE = "admin-sereq";

    private static final Logger logger = LogManager.getLogger(AdminSereqAction.class);

    @Override

import org.mockito.quality.Strictness;

import jcifs.SmbTransport;

`__name__ == "__main__"` の主な目的は、ファイルが次のコマンドで呼び出されたときに実行されるコードを用意することです:

<div class="termy">

```console
$ python myapp.py
```

</div>

ただし、次のように、別のファイルからインポートされるときには呼び出されません:

```Python
from myapp import app
```

#### より詳しい説明

ファイルの名前が `myapp.py` だとします。

以下の様に実行する場合:

<div class="termy">

```console
$ python myapp.py
```

</div>

import org.codelibs.fess.crawler.helper.MimeTypeHelper;

/**
 * MimeTypeHelperImpl is a helper class that detects the MIME type of a given input stream or filename.
 * It uses the Apache Tika library to detect the MIME type.
 *
 * <p>
 * This class provides methods to:
 * </p>
 * <ul>
 *   <li>Detect the MIME type based on the input stream and filename.</li>
