Django 简单历史不记录用户
Django Simple History not logging user
我正在使用 django-simple-history 来记录我模型中的更改。我已设法保存更改日志，但我总是在字段 history_user.
上得到 None
我正在关注 this tutorial。
这是我的模型：

def save(self, *args, **kwargs):

@property

我不知道我缺少什么来让用户登录。

这是我保存预订的地方：
def save_reservation(self, reservation_data, user, pk):
try:
reservation_to_save = models.Reservation.objects.get(booking=pk)
except:
raise CustomValidation(_("There is not such reservation {}".format(pk)), 'id', status.HTTP_400_BAD_REQUEST)
reservation_to_save.booking = reservation_data['booking']
reservation_to_save.agency = models.Agency.objects.get(id=reservation_data['agency'])
reservation_to_save.comment = reservation_data.get('comment', None)
reservation_to_save.status = reservation_data.get('status', 'UNCONFIRMED')
reservation_to_save.arrival_date = reservation_data['arrival_date']
reservation_to_save.departure_date = reservation_data['departure_date']
reservation_to_save.confirmation = reservation_data.get('confirmation', None)
reservation_to_save.is_invoiced = reservation_data.get('is_invoiced', False)
reservation_to_save.euroamerica = reservation_data.get('euroamerica', False)
reservation_to_save.save()
return reservation_to_save
根据 documentation，您必须将 HistoryRequestMiddleware 添加到 settings.py
中的中间件
像这样：
MIDDLEWARE = [
# ...
'simple_history.middleware.HistoryRequestMiddleware',
]
这至少是我的解决方案。
如果您不想使用此中间件，您可以手动设置用户，请参阅 this。
