Я пытаюсь отобразить данные с веб-сайта путем их удаления, сохранения и передачи в шаблон, но не могу ничего показать.
Когда пользователь нажимает на эту красную кнопку, он удаляет данные, такие как аммоний, NO2 и т. Д. Для этого местоположения.
Пока что я могу просмотреть и показать результат в терминале, но не могу показать его в этой таблице.
