最後に作成されたオブジェクトID

Question

My IDカラムは自動インクリメントですが、オブジェクトを作成して保存した後に別の関数にIDを送信する必要があります。

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) 

私はクエリセットに対して最新の機能を試しましたが、インデックスからリストを取得しました。

SetUserNotif機能

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()

あなたがactionObjのIDが必要な場合、あなたはそれを使用する必要があります。

setUserNotifs(request, actionObj.id)
