## Recap

You can use Pydantic's `Field` to declare extra validations and metadata for model attributes.

# Keep the existing "tf" container if it's already present.
# The container is not cleaned up automatically! Remove it with:
# docker rm tf
if ! docker container inspect tf >/dev/null 2>&1 ; then
  # Pass all existing TFCI_ variables into the Docker container
  env_file=$(mktemp)
  env | grep ^TFCI_ > "$env_file"

  WORKING_DIR="$TFCI_GIT_DIR"
  if [[ `uname -s | grep -P '^MSYS_NT'` ]]; then

Isso pode ser útil se, por exemplo, você mora em um país que restringe algumas URLs.

### Desativar a documentação automática

O primeiro passo é desativar a documentação automática, pois por padrão, ela usa o CDN padrão.

Para desativá-los, defina suas URLs como `None` ao criar seu aplicativo `FastAPI`:

```Python hl_lines="8"

correcte",andSpaces:" et des espaces ",badInt:"Vous n'avez pas saisi un numéro",badSecurityNumber:"Vous avez saisi un mauvais numéro de sécurité sociale",badUKVatAnswer:"Vous n'avez pas saisi un numéro de TVA au Royaume-Uni",badStrength:"Vous avez saisi un mot de passe pas assez sécurisé",badNumberOfSelectedOptionsStart:"Vous devez sélectionner au moins ",badNumberOfSelectedOptionsEnd:" réponse(s)",badAlphaNumeric:"Vous ne pouvez répondre qu'avec des caractères alphanumériques et des chiffres ",badAlphaNumericEx...

//
// passes NOATIME flag for reads on Unix systems to avoid atime updates.
func ReadFile(name string) ([]byte, error) {
	// Don't wrap with un-needed buffer.
	// Don't use os.ReadFile, since it doesn't pass NO_ATIME when present.
	f, err := OsOpenFile(name, readMode, 0o666)
	if err != nil {
		return nil, err
	}
	defer f.Close()
	st, err := f.Stat()
	if err != nil {
		return io.ReadAll(f)
	}

The `Union[str, None]` part allows your editor to provide better support, but it is not what tells FastAPI that this parameter is not required.

///

Then, we can pass more parameters to `Query`. In this case, the `max_length` parameter that applies to strings:

```Python
q: Union[str, None] = Query(default=None, max_length=50)
```

## Dependências globais

* It exposes an actual Python <a href="https://docs.python.org/3/library/tempfile.html#tempfile.SpooledTemporaryFile" class="external-link" target="_blank">`SpooledTemporaryFile`</a> object that you can pass directly to other libraries that expect a file-like object.

### `UploadFile`

`UploadFile` has the following attributes:

* `filename`: A `str` with the original file name that was uploaded (e.g. `myimage.jpg`).

  /**
   * Returns an {@code ImmutableList} containing all of the elements from this fluent iterable in
   * proper sequence.
   *
   * <p><b>{@code Stream} equivalent:</b> {@code ImmutableList.copyOf(stream.iterator())}, or pass
   * {@link ImmutableList#toImmutableList} to {@code stream.collect()}.
   *
   * @throws NullPointerException if any element is {@code null}
   * @since 14.0 (since 12.0 as {@code toImmutableList()}).
   */

### Include the custom docs

Now you can create the *path operations* for the custom docs.

You can reuse FastAPI's internal functions to create the HTML pages for the docs, and pass them the needed arguments:

* `openapi_url`: the URL where the HTML page for the docs can get the OpenAPI schema for your API. You can use here the attribute `app.openapi_url`.
* `title`: the title of your API.
