## Про данные формы ("Form Data")

Способ, которым HTML-формы (`<form></form>`) отправляют данные на сервер, обычно использует "специальную" кодировку для этих данных, отличную от JSON.

**FastAPI** позаботится о том, чтобы считать эти данные из нужного места, а не из JSON.

                                    <la:errors property="_global"/>
                                </div>
                                <div class="form-group row">
                                    <label for="name" class="col-sm-3 text-sm-right col-form-label"><la:message
                                            key="labels.group_name"/></label>
                                    <div class="col-sm-9">
