Я хочу использовать шаблон входа, но я не уверен, как отправить данные из этого шаблона в мой Flask API. Я читал, что состояния только в компонентах. Это правда? Я попытался вызвать функцию Register внутри рендера из другого файла, в котором есть компонент, но я получил ошибку о недопустимых хуках.
