Есть класс, сохраняющий в кэш формы запроса, для его создания используется текущий пользователь. Выбрасывает ошибку при создании объекта класса, хотя данные корректные и отладчик показывает что все передается верно, однако ошибка все же есть. В чем может быть причина?
Создание объекта:
cache, created = ContactCache.objects.get_or_create(user_id=request.user.id)

Класс кэша:
class ContactCache(models.Model):
user_id = models.IntegerField(blank=True, unique=True)
KEY = models.IntegerField(default='', null=True, blank=True)
info = models.CharField(max_length=100, default='', blank=True)
type = models.CharField(max_length=100, default='', blank=True)
subject = models.CharField(max_length=100, default='', blank=True)
Возможно ли, что в request.user.id лежит не int?
