python - 其余框架 'tuple'对象没有属性 '_meta'

Django抛出下一个异常:

restframework“元组”对象没有属性“_meta”

模型

class BDetail(models.Model):
   lat = models.FloatField(blank=True, null=True)
   lng = models.FloatField(blank=True, null=True)

   class Meta:
       # managed = False
       db_table = 'b_detail'

看法

from .models import BDetail
from .serializers import BDetailSerializer
from rest_framework import viewsets

class BDetailList(viewsets.ModelViewSet):
        queryset = BDetail.objects.all()
        serializer_class = BDetailSerializer

网址

from django.conf.urls import url, include
from bdetail import views
from rest_framework import routers

router = routers.DefaultRouter()
router.register(r'bdetail', views.BDetailList)

urlpatterns = [
    url(r'^', include(router.urls), name='bdetail')
]

序列化器

from .models import BDetail
from rest_framework import serializers

class BDetailSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = BDetail,
        fields = ('lat', 'lng')

环境:

最佳答案

您在,序列化程序中的BDetail模型名称之后有BDetailSerializer。删除它，您的代码将起作用。

建议:在serializers.ModelSerializer序列化程序中继承BDetailSerializer而不是serializers.HyperlinkedModelSerializer，即:

class BDetailSerializer(serializers.ModelSerializer):
    class Meta:
        model = BDetail
        fields = ('lat', 'lng')
