Что вызывает данную ошибку ?
Model class builtins.Topic doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS ?
Запускается файл (models.py) вот его код:
from django.db import models
class Topic(models.Model):
"""Тема, которую изучает пользователь."""
text = models.CharField(max_length=200)
date_added = models.DateTimeField(
auto_now_add=True)
def __str__(self):
return self.text
А вот код файла(settings.py) :
INSTALLED_APPS = [
# Мои приложения.
'learning_logs',
# Дефолтные приложения Django.
'django.contrib.admin',
]
А при запуске из cmd появляется такая ошибка:
Traceback (most recent call last):
