DRF 1.7.1 'str' 对象没有属性'resolve' AttributeError

Question

我正在尝试使我的第一个 DRF api 正常工作，但是当我尝试使用 curl 或 Web 浏览器发出 GET 请求时，即我得到的 'str' 对象没有属性 'resolve' AttributeError。
我用于测试的地址是：http://0.0.0.0:8000/polls/expediteur/

我在下面留下一些代码sn-ps。

urls.py

from django.conf.urls import patterns, url
from polls import views
# from django.contrib import admin

urlpatterns = patterns('',
    # Examples:
    # url(r'^admin/', include(admin.site.urls)),
    "polls.view",
    url(r'^Expediteur/$', views.ExpeViewSet.as_view(), name="expediteur"),
)

models.py

from django.db import models

# Create your models here.

class Expediteur(models.Model):
    nom = models.CharField(max_length=50)
    prenom = models.CharField(max_length=100)
    adresse = models.CharField(max_length=200)
    tel = models.IntegerField()

views.py

from django.shortcuts import render
from rest_framework import viewsets
from rest_framework.views import APIView
from rest_framework.response import Response
from polls.serializers import ExpediteurSerializer, DestinataireSerializer, LettrePrioSerializer, TypeLettreRecoSerializer, LettreRecoSerializer, TimbrePrioSerializer, TimbreRecoSerializer
from polls.models import Expediteur, Destinataire, LettrePrio, TypeLettreReco, LettreReco, TimbrePrio, TimbreReco
from rest_framework import status, HTTP_HEADER_ENCODING

# Create your views here.

class ExpeViewSet(APIView):
    serializer_class = ExpediteurSerializer

    def get(self, request):
        queryset = Expediteur.objects.all()
        serializer = ExpediteurSerializer(queryset)
        return Response(serializer.data)

    def post(self, request):
        serializer = self.serializer_class(data=request.DATA)
        return Response(status=status.HTTP_201_CREATED)

serializers.py

from rest_framework import serializers
from polls.models import Expediteur, Destinataire, LettrePrio, TypeLettreReco, LettreReco, TimbrePrio, TimbreReco


class ExpediteurSerializer(serializers.Serializer):
    nom = serializers.CharField(required=True, allow_blank=False, max_length=50)
    prenom = serializers.CharField(required=True, allow_blank=False, max_length=100)
    adresse = serializers.CharField(required=True, allow_blank=False, max_length=200)
    tel = serializers.IntegerField(required=True)

    def create(self, validated_data):
        return Expediteur.objects.create(**validated_data)
    def update(self, instance, validated_data):
        instance.nom = validated_data.get('nom', instance.nom)
        instance.prenom = validated_data.get('prenom', instance.prenom)
        instance.adresse = validated_data.get('adresse', insatnce.adresse)
        instance.tel = validated_data.get('tel', instance.tel)
        instance.save()
        return instance

已经有两个 ExpediteurObject，我的目标是能够在移动应用程序中与之交互。我已经检查了'str' object has no attribute 'resolve' when access admin site 和http://redsymbol.net/articles/django-attributeerror-str-object-no-attribute-resolve/

看看我是否可以解决问题，但我没有找到问题的答案。

我也在下面留下了回溯

从patterns() 中删除"polls.view", 字符串：

urlpatterns = patterns('',
    # Examples:
    # url(r'^admin/', include(admin.site.urls)),
    url(r'^Expediteur/$', views.ExpeViewSet.as_view(), name="expediteur"),
)

要访问/polls/expediteur/ 地址的视图，请将网址更改为：

url(r'^polls/expediteur/$', views.ExpeViewSet.as_view(), name="expediteur"),

或者，如果此 urls.py 来自 polls 应用程序：

url(r'^expediteur/$', views.ExpeViewSet.as_view(), name="expediteur"),
