Django Rest Framework - 針對URL進行過濾 - TypeError as_view（）只需要1個參數（給出3個參數）

Question

所以我試圖使用Django Rest Framework。它將用作Ionic混合應用程序的REST API。我需要能夠通過街道名稱參數（基於距離用戶GPS位置最近的街道）從應用發送請求，該請求返回包含該街道名稱的數據。我正在嘗試遵循文檔中的Filtering against the URL指南。

我的代碼如下所示：

**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) 

我不強的正則表達式，但我想，我需要把在本地主機/ API /筆記/ streetname /查詢API，用於與該資料街道名稱？

什麼情況是，我得到的錯誤：在/ API /筆記/ Vestergade/ as_view 類型錯誤（）將（給定3）正好1參數

我可以似乎沒有弄清楚這三個論點在哪裏給出。

Answer 1

在此只是偶然試圖限制我的API的當前用戶的請求。

這是關於視圖的類型：generics.ListAPIView。它不應該是一個視圖，但ViewSet - 檢查這個問題here

更改爲viewsets.ModelViewSet或類似的東西。

Answer 2

我注意到了兩件事情，我認爲這可以幫助您解決問題。

1. 擺脫router.register(r'notes', views.NoteView, base_name='notes')
2. 無論是在url('^notes/(?P<location>.+)/$', views.NoteView.as_view()),添加/api或簡單地訪問/notes/*LOCATION*
