Question

所以我试图使用Django Rest Framework。它将作为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。我试图按照文档中的Filtering against the URL指南进行操作。

我的代码如下所示：

**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)

我在正则表达式方面不强，但我想我需要在localhost / api / notes / streetname /中查询api以获取该街道名称的数据？

我收到的错误是： / api / notes / Vestergade中的TypeError / as_view（）只需1个参数（给定3个）

堆栈跟踪：

Environment:

Request Method: GET
Request URL: http://localhost:8000/api/notes/Vestergade/

Exception Type: TypeError at /api/notes/Vestergade/
Exception Value: as_view() takes exactly 1 argument (3 given)

我似乎无法弄清楚这三个论点的位置。

Answer 1

偶然发现这个尝试将我的API请求限制为当前用户。

这是关于视图的类型：viewsets.ModelViewSet。它不应该是View，而是ViewSet - 请检查此问题here

将其更改为(\n[0-9]{3})[ 0-9]{4}([^\n]*)或类似内容。

Answer 2

我注意到的两件事我认为可以帮助您解决问题。

摆脱router.register(r'notes', views.NoteView, base_name='notes')
在/api中添加url('^notes/(?P<location>.+)/$', views.NoteView.as_view()),或只访问/notes/*LOCATION*

Django Rest Framework - 针对URL过滤 - TypeError as_view（）只需1个参数（给定3个）
