`Field` funciona de la misma manera que `Query`, `Path` y `Body`, tiene todos los mismos parámetros, etc.

/// note | Detalles técnicos

En realidad, `Query`, `Path` y otros que verás a continuación crean objetos de subclases de una clase común `Param`, que es a su vez una subclase de la clase `FieldInfo` de Pydantic.

Y `Field` de Pydantic también regresa una instance de `FieldInfo`.

Por exemplo:

{* ../../docs_src/conditional_openapi/tutorial001_py310.py hl[6,11] *}

Aqui declaramos a configuração `openapi_url` com o mesmo padrão de `"/openapi.json"`.

E então a usamos ao criar a aplicação `FastAPI`.

Então você pode desabilitar o OpenAPI (incluindo a documentação da interface do usuário) definindo a variável de ambiente `OPENAPI_URL` como a string vazia, como:

<div class="termy">

```console

import org.codelibs.fess.unit.UnitFessTestCase;
import org.junit.jupiter.api.Test;

public class SystemUtilTest extends UnitFessTestCase {

    @Test
    public void test_getSearchEngineHttpAddress_null() {
        // Clear the system property to test null case
        String originalValue = System.getProperty(Constants.FESS_SEARCH_ENGINE_HTTP_ADDRESS);
        System.clearProperty(Constants.FESS_SEARCH_ENGINE_HTTP_ADDRESS);

        try {

      }

      // We can't measure the body's size without the sizes of its components.
      val contentLength = body.contentLength()
      if (contentLength == -1L && countBytes) {
        byteCountBuffer!!.clear()
        return -1L
      }

      sink.write(CRLF)

      if (countBytes) {
        byteCount += contentLength
      } else {
        body.writeTo(sink)
      }

      sink.write(CRLF)

        List<FileNotifyInformation> result = sut.watch();

        assertNull(result, "Cancelled watch should return null");
        verify(tree, times(1)).close();
    }

    // Error code 0x10C should clear the notify list and return it
    @Test
    @DisplayName("watch() clears notify list on error 0x10C and returns it")
    void watch_clearsList_onError10C() throws Exception {

```Python
UserInDB(
    username = user_dict["username"],
    password = user_dict["password"],
    email = user_dict["email"],
    full_name = user_dict["full_name"],
)
```

#### Créer un modèle Pydantic à partir du contenu d'un autre { #a-pydantic-model-from-the-contents-of-another }

Comme dans l'exemple ci-dessus nous avons obtenu `user_dict` depuis `user_in.model_dump()`, ce code :
