如何从具有"pk":50 的会话中删除对象并将其存储到所有页面。当我修改请求会话时,我将 SESSION_SAVE_EVERY_REQUEST=True 添加到 Settings.py 和 request.session.modified = True 添加到正上方行,但没有效果。

法典
def setNotifRead(request, notif_id):
notifObject = Notification.objects.filter(pk=notif_id)
notifObject.update(unread=0)
notifications = request.session['notifications']
request.session.modified = True
del notifications[notif_id] # Something should be done here
return
需要循环访问数据并筛选没有相关 ID 的项目。
notifications = [item for item in request.session['notifications'] if item['id'] != notif_id
request.session['notifications'] = notifications
