python之Django Rest Framework之针对 URL 进行过滤之TypeError as_view() 正好需要 1 个参数(给定 3 个)

所以我正在尝试使用 Django Rest Framework。它将充当 Ionic 混合应用程序的 REST API。我需要能够使用街道名称参数(基于距离用户 GPS 位置最近的街道)从应用程序发送请求，该请求返回包含该街道名称的数据。我正在尝试关注 Filtering against the URL文档中的指南。

我的代码是这样的:

**urls.py** 
router = DefaultRouter() 
router.register(r'notes', views.NoteView, base_name='notes') 
 
urlpatterns = patterns('', 
                   url(r'^api/', include(router.urls)),namespace='rest_framework')), 
                   url('^notes/(?P<location>.+)/$', views.NoteView.as_view()), 
) 
 
**serializers.py** 
class NoteSerializer(serializers.ModelSerializer): 
    place = serializers.StringRelatedField() 
 
    class Meta: 
        model = Note 
        fields = ('text_content', 'from_date', 'place') 
 
**views.py** 
class NoteView(generics.ListAPIView): 
    serializer_class = NoteSerializer 
 
    def get_queryset(self): 
        location = self.kwargs['location'] 
        wreturn Note.objects.filter(place__name__contains=location) 

我不擅长正则表达式，但我想我需要放入 localhost/api/notes/streetname/来查询 api 中具有该街道名称的数据？

我得到的错误是: /api/notes/Vestergade/处的类型错误 as_view() 恰好接受 1 个参数(给定 3 个)

我似乎无法弄清楚这 3 个参数是在哪里给出的。

请您参考如下方法:

只是偶然发现这个试图限制我的 API 对当前用户的请求。

是关于 View 类型的:generics.ListAPIView。它不应该是一个 View ，而是一个 View 集——检查这个问题 here

将其更改为 viewsets.ModelViewSet 或类似内容。
