django dumpdata => load on heroku

Question

Я пытаюсь загрузить данные из моей базы данных sqlite в postgres heroku, но он не работает.

Сначала я побежал:

manage.py dumpdata --indent 1 > data.json 

, а затем я попытался загрузить его на Heroku с (после того, как я совершил файл Heroku):

heroku run python manage.py loaddata data.json 

, но он просто не работает. ..

он дал мне ошибки:

Running `python manage.py loaddata data.json` attached to terminal... up, run.92

В чем может быть проблема?

Answer 1

Конец StackTrace имеет ключ:

relation "django_content_type"  does not exist 
LINE 1: UPDATE "django_content_type" SET "name" = 'log entry', "app_... 

В таблице django_content_type не существует. Попробуйте запустить миграции:

heroku run python manage.py migrate 

или, если вы используете старую версию:

heroku run python manage.py setupdb
