Question

我有一个简单的视图，“运动员”应该只显示一个名称和id，以及一些额外的相关数据。但是我从记录中取回整个数据集。

@api_view(['GET'])
@permission_classes((permissions.AllowAny,))
def get_by_years(request):
    athletes = AthleteProfile.objects.filter(owner=request.user)
    athletes_json = NotesAthleteSerializer(athletes, many=True)

    return Response(athletes_json.data)

我期待这种格式：

[
    {
        "id": 215,
        "first_name": "Joseph",
        "last_name": "Doe",
        "graduation_year": 2016,
        "notes": "fdgdfg wew",
    }
]

相反，它提供了所有细节，如：

[
    {
        "id": 215,
        "first_name": "Joseph",
        "last_name": "Doe",
        "graduation_year": 2016,
        "notes": "fdgdfg wew",
        "email": "joedoe@gmail.com",
        "date_of_birth": null,
        "mobile_number": "123-234-23271",
        "team_name": "Wildcats",
        "coach_name": "",
        "coach_email": "",
        "coach_number": "",
        "event_seen": "NA",
        "jersey_number": 1,
        "rank": 2,
        "public_record": false,
        "notify_key": "f9781efee667d26cdeb6cead447e49bdd8a836a3",
        "notified_on": "2016-11-02T10:58:37.131000Z",
        "level_of_interest": "1",
        "user": null,
        "owner": 30,
        "sport_position": null,
        "next_step": null,
        "next_steps": [
            1,
            2
        ]
    }
]

以下是我的序列化设置：

class NotesAthleteSerializer(serializers.ModelSerializer):

    class Meta:
        model = AthleteProfile
        field = ('id', 'first_name', 'last_name', 'graduation_year', 'notes')

我是否错误地初始化了“NotesAthleteSerializer”？

我尝试了其他几种定义序列化的方法，例如：

class NotesAthleteSerializer(serializers.ModelSerializer):
    first_name = serializers.CharField(read_only=True)
    last_name = serializers.CharField(read_only=True)
    graduation_year = serializers.IntegerField(read_only=True)
    notes = serializers.CharField(read_only=True)

    class Meta:
        model = AthleteProfile
        read_only_fields = ('id', 'first_name', 'last_name', 'graduation_year', 'notes')

和

class NotesAthleteSerializer(serializers.ModelSerializer):
    class Meta:
        model = AthleteProfile
        read_only_fields = ('id', 'first_name', 'last_name', 'graduation_year', 'notes')

和

class NotesAthleteSerializer(serializers.ModelSerializer):
    first_name = serializers.CharField(read_only=True)
    last_name = serializers.CharField(read_only=True)
    graduation_year = serializers.IntegerField(read_only=True)
    notes = serializers.CharField(read_only=True)

    class Meta:
        model = AthleteProfile
        field = ('id', 'first_name', 'last_name', 'graduation_year', 'notes')
        read_only_fields = ('id', 'first_name', 'last_name', 'graduation_year', 'notes')

Answer 1

我是一个完全白痴，我有＆＃34; field＆＃34;而不是＆＃34;字段＆＃34; ....

class NotesAthleteSerializer(serializers.ModelSerializer):

    class Meta:
        model = AthleteProfile
        field = ('id', 'first_name', 'last_name', 'graduation_year', 'notes')

相反，它必须是：

class NotesAthleteSerializer(serializers.ModelSerializer):

    class Meta:
        model = AthleteProfile
        fields = ('id', 'first_name', 'last_name', 'graduation_year', 'notes')

未过滤的ModelSerializer中的指定字段
