SetUserNotif函数

Question

我的ID列是自动递增的，但我必须在创建和保存对象后将ID发送到另一个函数。

actionObj = ScAnsAction()

#actionObj.id -- auto increment

actionObj.user_id = getUserID(request)
actionObj.action_id = 6
actionObj.req_id = request_id
actionObj.a_date = i.strftime("%Y-%m-%d")
actionObj.save()

setUserNotifs(request,#should be latest above objectID)

我在查询集上尝试了最新的功能，但我从列表中删除了列表。

SetUserNotif函数

def setUserNotifs(request,request_id):
    username = request.user.username
    object_id_list = ScAns.objects.filter(username=username).values_list('id',flat=True)
    actionUsers =  ScAnsAction.objects.filter(req_id=request_id).values_list('user_id',flat=True).exclude(user_id=object_id_list).distinct()
    requestCreaterUsername = ScRequests.objects.filter(id=request_id).values_list('sender',flat=True)
    requestCreaterID = ScAns.objects.filter(username=requestCreaterUsername).values_list('id',flat=True)

    # send notification to users who has been commented on that request
    for actionUser in actionUsers:
        actionObj = ScActionNotif()
        actionObj.action_id = request_id
        actionObj.user_id = actionUser
        actionObj.notif = "unread"
        actionObj.save()

    # send notification to the creator of the request
    actionObj = ScActionNotif()
    actionObj.action_id = request_id
    actionObj.user_id = requestCreaterID[0]
    actionObj.notif = "unread"
    actionObj.save()

如果您需要actionObj的ID，则应该使用它：

setUserNotifs(request, actionObj.id)

上次创建的对象ID
