А вот таблица, которую я хочу добавить в БД через файл подключения model.pyприложение.

class BModel(models.Model):
    user              = models.ForeignKey(User, related_name="reports_user")
    dataset           = models.ForeignKey(DatasetRecord, related_name="dataset_record")
    name              = models.CharField(max_length=100)
    created_date      = models.DateTimeField(default=timezone.now, blank=True, null=True)
    updated_date      = models.DateTimeField(default=timezone.now)

    def __unicode__(self):
        return '%s' % self.id

    class Meta:
        app_label = 'daas'

Вам нужно изменить app_label на имя приложения, которое вы добавили в установленные_apps внутри settings.py

app_label = 'connection'

Ссылка: app_label django docs

И ответ на вопрос "но я все еще в замешательстве, что у меня все работало, файл с app_label = 'daas' и создал другие таблицы, но почему на этот раз это не работает", может быть,this «Если модель определена вне приложения в INSTALLED_APPS, она должна объявить, к какому приложению она принадлежит», не уверен, пока не увижу реальные приложения.
