не работает редактор ckeditor в django

не работает ckeditor за пределами админки, не показывает поля редактирования итд.

• установил по инструкции https://github.com/django-ckeditor/django-ckeditor#installation
• collectstatic, после изменения models makemigrations, migrate
• тут указано https://github.com/django-ckeditor/django-ckeditor#id9, что для работы с полями за пределами admin, надо добавлять статические файлы html, но не помогло
