Django session delete json object - json

Question

How can I remove object from session which has 'pk':50 and store it for all pages. I added SESSION_SAVE_EVERY_REQUEST=True to Settings.py and request.session.modified = True to just above line when I modify request session, but there was no effect.
Json looks like
[
{
"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"
}
}
]
code
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

You will need to iterate through the data and filter the items that don't have the relevant ID.
notifications = [item for item in request.session['notifications'] if item['id'] != notif_id
request.session['notifications'] = notifications
