Django会话删除json对象

Question

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并将request.session.modified = True添加到上面的行，但没有效果。

Json看起来像

[
{
    "pk": 50, 
    "model": "notifications.notification", 
    "fields": {
        "recipient": 81, 
        "verb": "commented", 
        "emailed": false, 
        "action_object_object_id": "", 
        "level": "info", 
        "deleted": false, 
        "timestamp": "2017-01-25T11:18:53.197Z", 
        "target_content_type": null, 
        "actor_object_id": "1", 
        "action_object_content_type": null, 
        "target_object_id": "790", 
        "actor_content_type": 3, 
        "unread": true, 
        "data": "\"\"", 
        "public": true, 
        "description": "commented on your request"
    }
}, 
{
    "pk": 38, 
    "model": "notifications.notification", 
    "fields": {
        "recipient": 81, 
        "verb": "commented", 
        "emailed": false, 
        "action_object_object_id": "", 
        "level": "info", 
        "deleted": false, 
        "timestamp": "2017-01-24T12:23:08Z", 
        "target_content_type": null, 
        "actor_object_id": "1", 
        "action_object_content_type": null, 
        "target_object_id": "790", 
        "actor_content_type": 3, 
        "unread": true, 
        "data": "\"\"", 
        "public": true, 
        "description": "commented on your request"
    }
}
]

码

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

您需要遍历数据并过滤不具备相关ID的项目。

notifications = [item for item in request.session['notifications'] if item['id'] != notif_id
request.session['notifications'] = notifications
