Django Restful API返回Empty Json

Question

我正在使用rest_framework库构建django restful json API，但是即使我在数据库表中有很多记录，当我向它提交请求时，它也会返回空的json []。这是我的代码

models.py

class Member(models.Model):
    email = models.EmailField()
    mobile = models.CharField(max_length=11, null=False)
    username = models.CharField(max_length=20, null= False, help_text="Username")
    password = models.CharField(max_length=15, null=False, help_text="Password")
    mobile_id = models.CharField(max_length=100, null=True, blank=True)
    joined_date = models.DateTimeField(auto_now_add=True)

serializers.py

class MemberSerializer(serializers.Serializer):
    class Meta:
        model = Member
        fields = ('email', 'mobile', 'username', 'joined_date')

views.py

class MemberAPI(viewsets.ModelViewSet):
    serializer_class = MemberSerializer
    queryset = Member.objects.all()

urls.py

router = DefaultRouter()
router.register(r'member', MemberAPI, base_name='member')
urlpatterns = router.urls

我知道了 看来，我在serializers.py中继承了序列化的基本通用类。

我应该像这样从ModelSerializer继承

class MemberSerializer(serializers.ModelSerializer):
    class Meta:
        model = Member
        fields = ('email', 'mobile', 'username', 'joined_date')
