Question

我有这样的models.py

GENDER =(
    ('MALE',1),
    ('FEMALE',2),
    ('OTHERS',3)
    )

class User(BaseModel, AbstractUser):
    type = models.IntegerField(choices=USER_TYPE,null=True)
    gender = models.IntegerField(choices=GENDER,null=True)

列出学生的Views.py就是这样

def list(self,request):

    for adm in StudentAdmission.objects.all():
        user = adm.student.user

        tmp['user']  = UserGetSerializer(user).data

        ud = UserDetail.objects.filter(user_id=user.id)
        if ud:
            tmp['user_detail'] = UserDetailSerializer(ud.first()).data

像这样的serializer.py ...

class UserBaseSerializer(serializers.Serializer):
    first_name = serializers.CharField(max_length=120,required=True)
    last_name = serializers.CharField(max_length=120,required=True)
    email = serializers.EmailField(required=True)


class UserSerializer(UserBaseSerializer):
    gender = serializers.IntegerField()
    type = serializers.IntegerField(default=3)


class UserGetSerializer(UserBaseSerializer):
    gender = serializers.SerializerMethodField()
    type = serializers.IntegerField(default=3)

    def get_gender(self, obj):

        #Here Confusion

        return {'id':obj.gender, 'value':value}

它以性别返回输出1，而不是返回男性。我要返回男性，而不是1。为此，我做了一个get_gender（）函数从元组中查找并返回该对象ID的值。所以我的问题是我该如何编写get_gender（）函数来查找Gender元组。

对不起英语，希望您能理解我的问题

使用模型的get_FOO_display方法：

def get_gender(self, obj):
    return obj.get_gender_display()

或仅指定是字段的来源：

class UserGetSerializer(UserBaseSerializer):
    gender = serializers.CharField(source='get_gender_display')

请注意，您的GENDER元组的值有误。应该像这样(actual_value, human_readable)：

GENDER =(
    (1, 'MALE'),
    (2, 'FEMALE'),
    (3, 'OTHERS')
)

如何在Serializer中查找元组？
