int() 参数必须是字符串、类似字节的 object 或数字，而不是 'dict'

Question

The function not entering into if condition, because round is dict and match_round is int, so showing error, how solve this?

my modelviewset

 def destroy(self, request, *args, **kwargs):
    gameevent = self.get_object().gameevent
    match_round = self.get_object().match_round
    print(gameevent)
    print(match_round)
    round = Matchscore.objects.filter(gameevent=gameevent, match_round=match_round).values_list("match_round",flat=True).aggregate(Max("match_round"))
    print(round)
    if round == match_round:
        Matchscore.objects.get(match_round=round).delete()
        response = {"result": "successfully removed"}
    else:
        response = {"result": "can't delete this round"}
    return Response(response)

Answer 1

try this,

 def destroy(self, request, *args, **kwargs):
    gameevent = self.get_object().gameevent
    match_round = self.get_object().match_round
    print(gameevent)
    print(match_round)
    round = Matchscore.objects.filter(gameevent=gameevent, match_round=match_round).values_list("match_round",flat=True).aggregate(Max("match_round"))['match_round__max']
    print(round)
    if round == match_round:
        Matchscore.objects.get(match_round=round).delete()
        response = {"result": "successfully removed"}
    else:
        response = {"result": "can't delete this round"}
    return Response(response)

If you want to compare Django DB objects for identity in the DB, ie sharing the same DB row, then test their pk for equality.

if a_round.pk == match_round.pk:

if by some other metric based on other fields, code this explicitly.

In the question, round is not a Django DB object at all, it's a values_list based on some filtered objects. So you need to extract some values from the result of that query, and the corresponding values from match_round , and compare them. I don't have sufficient insight into the problem to suggest the nature of that comparison.
