У меня есть создатель / редактор поста на сайте, который я пишу.Я успешно смог создать пост (сохраняет в json), получить выпадающий список меню созданного поста из той же базы данных (и во-вторых, все posts.json, откуда берется список постов), изаполнить формы элементов указанной информацией.Затем я могу сохранить его, и он действительно записывает в файл.Проблема в том, что данные в текстовых полях не обновляются в сохраненном сообщении.Сохраняет исходные данные, переданные с мультидиктом.Я могу вручную обновить его как: Ex.form.title.data = "Новый заголовок", и он сохраняется как таковой, поэтому я знаю, что он правильно обрабатывает все в конце сохранения.Если у кого-то есть идея, как получить обновленную информацию из полей формы, будьте благодарны.Спасибо.
