django - 如何在django_rest_framework APIView中配置ID参数

Question

我的目标是指定允许我在 URL 中输入 ID 的行为。

目前，我可以向 URL“localhost:8000/api/players/?id=#”发送 GET、PUT 和 PATCH 请求，其中哈希值代表玩家 ID

我想更新我的代码，以了解如果我向“localhost:8000/api/players/2”发送 GET/PUT/PATCH 请求，我正在寻找 id=2 的玩家

我的模型.py

class player(models.Model):
    first_name = models.CharField(max_length=50)
    last_name = models.CharField(max_length=50)
    team = models.CharField(max_length=50)
    position = models.CharField(max_length=50)
    number = models.IntegerField()

    def __str__(self):
        return "{}, {}".format(self.first_name, self.last_name)

我的序列化器.py

class playerSerializer(serializers.ModelSerializer):

    class Meta:
        model = player
        fields = ['id', 'first_name', 'last_name', 'team', 'position', 'number']

    def put(self, request, *args, **kwargs):
        id = request.query_params["id"]
        player_object = player.objects.get(id=id)

        data = request.data

        player_object.first_name = data["first_name"]
        player_object.last_name = data["last_name"]
        player_object.team = data["team"]
        player_object.position = data["position"]
        player_object.number = data["number"]

        player_object.save()

        serializer = playerSerializer(player_object)
        return Response(serializer.data)
    
    def patch(self, request, *args, **kwargs):
        id = request.query_params["id"]
        player_object = player.objects.get(id=id)

        data = request.data

        player_object.first_name = data.get('first_name', player_object.first_name)
        player_object.last_name = data.get('last_name', player_object.last_name)
        player_object.team = data.get('team', player_object.team)
        player_object.position = data.get('position', player_object.position)
        player_object.number = data.get('number', player_object.number)

        player_object.save()
        serializer = playerSerializer(player_object)
        return Response(serializer.data)

我的 urls.py

urlpatterns = [
    url('players', playerList.as_view()),
]

我已经被这个问题困扰了几天......任何指导将不胜感激。

谢谢， 奥斯汀H
