3-й день мучаюсь с данной проблемой. На heroku имеется БД MySQL. Также я создал django приложение, которое подключается к данной БД. Если я запускаю его у себя на компьютере, то у меня все работает. Однако если я запущу приложение на heroku, то у меня появляется ошибка:
relation "station" does not exist
LINE 1: ...ongitude", "station"."Type", "station"."Link" FROM "station"
Ощущение будто приложение вообще не видит таблицы БД. Как исправить данную проблему?
Вот полный Traceback:File "/app/.heroku/python/lib/python3.7/site-packages/django/db/backends/utils.py" in _execute
85. return self.cursor.execute(sql, params)
The above exception (relation "station" does not exist
LINE 1: ...ongitude", "station"."Type", "station"."Link" FROM "station"
^
) was the direct cause of the following exception:
