如何在 Django drf 中获得数组格式的响应？我是 python-drf 编程的新手。请帮助解决问题。

我只想要数组格式的 team_users，但现在它以数组形式返回，每个字母用引号分隔。

{
    "id": 3,
    "team_name": "team 3",
    "team_icon": "/media/icon/underground_3Dz5sfD.png",
    "team_users": [
        "[",
        "'",
        "s",
        "k",
        "a",
        "r",
        "a",
        "n",
        "7",
        "1",
        "4",
        "@",
        "g",
        "m",
        "a",
        "i",
        "l",
        ".",
        "c",
        "o",
        "m",
        "'",
        ",",
        " ",
        "'",
        "s",
        "a",
        "m",
        "p",
        "l",
        "e",
        "1",
        "2",
        "3",
        "@",
        "g",
        "m",
        "a",
        "i",
        "l",
        ".",
        "c",
        "o",
        "m",
        "'",
        "]"
    ]
},

要求的格式是：

    "id": 3,
    "team_name": "team 3",
    "team_icon": "/media/icon/underground_3Dz5sfD.png",
    "team_users": ["first_email", "second_email"]

这是serializers.py中的代码

class TeamSerializer(serializers.ModelSerializer):
        team_users = serializers.ListField(child=serializers.EmailField(min_length=0, max_length=100))


        class Meta():
            model=Team
            fields = ('id','team_name', 'team_icon', 'team_users')

models.py

class Team(models.Model):
    team_name = models.CharField(max_length=255)
    team_icon = models.ImageField()
    team_users = models.EmailField()

在views.py中

class GetTeam(APIView):


    def get(self, request, *args, **kwargs):
        data_list = []
        teams = models.Team.objects.all()
        for team in teams:
            data_list.append(serializers.TeamSerializer(team).data)
        return Response(data_list)

【解决方案1】：

一种可能的解决方案是使用“SerializerMethodField”

class TeamSerializer(serializers.ModelSerializer):

    team_users = serializers.SerializerMethodField(read_only=True)

    def get_team_users(self, obj):
        return [x.email for x in obj.team_users]

还取决于您的团队用户模型，但您可以根据自己的需要进行调整。

【讨论】：

得到这个错误 AttributeError 'str' object has no attribute 'email'
这就是我的意思，您需要将模型添加到您的问题中。没有那个，我只假设团队用户是具有电子邮件属性的模型。
你能帮我解决问题吗，添加模型和视图
您的模型设计可能不是您想要的，并且超出了在 SO 上的范围。您可能希望团队用户成为模型并添加与团队模型的关系，以便团队中可以有多个用户。

【解决方案2】：

class GetTeam(APIView):

    def get(self, request, *args, **kwargs):
        teams = models.Team.objects.all()
        return Response(serializers.TeamSerializer(team, many=True).data)

If the field is used to represent a to-many relationship, you should add the many=True flag to the serializer field.
