Джанго не видит ни одного из установленных приложений

/ 22 апреля 2019

После небольшой миграции я продолжаю получать следующую ошибку от команды runserver Джанго:

RuntimeError: Класс модели captcha.models.CaptchaStore не объявляет явную метку app_label и не находится в приложении в INSTALLED. _APPS.

Это вызвано django-simple-captcha который работал довольно долго (месяц). Я не изменил что-то в этом приложении. Я удалил его, и теперь Django не может найти приложение ADMIN, так что оно как-то связано с целостностью.

Мои настройки такие: 


INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    # custom
    "boats.apps.BoatsConfig",
    "articles.apps.ArticlesConfig",
    #3rd party
    "captcha",
    "bootstrap4",
    "django_cleanup",
    "easy_thumbnails",
    "social_django",
    "crispy_forms",
    "extra_views",
    "debug_toolbar",
    "reversion",
    "dynamic_validator",
    "django.forms",  # new for a custom widgets

Как я могу решить эту проблему? Это кажется странным ... Или, как альтернатива, как откатить последнюю миграцию?

Это был циркулирующий импорт.Решение было найдено, благодаря Alasdair.Я спрятал 2 импорта внутри метода ... 

    def save(self, force_insert=False, force_update=False, using=None,
    update_fields=None):
        from articles.models import SubHeading, UpperHeading
        SubHeading.objects.update_or_create(name=self.boat_name, order=0,
                                            foreignkey_id=93)
        models.Model.save(self, force_insert=False, force_update=False, using=None,
                          update_fields=None)

Полагаю, вы только что удалили django-simple-captcha? Удалите "captcha" из INSTALLED_APPS, иначе Django все равно будет искать приложение.

И, конечно, удалите все CaptchaField с из ваших моделей.
