Question

我正在尝试使用django rest框架创建一个api。我需要一个视图来列出数据表中的所有项目，另一个视图根据他们的id输出个人的数据。

列表视图适用于＆＃39; api / bios /＆＃39;。但是，在向网址添加ID时收到以下错误：

找不到HTTP 404 允许：GET，PUT，PATCH，DELETE，HEAD，OPTIONS Content-Type：application / json 变化：接受

{ ＆＃34;详细信息＆＃34;：＆＃34;未找到。＆＃34; }

views.py

from rest_framework.response import Response
from rest_framework import status
from rest_framework import generics, mixins
from api.models import Playerbios
from api.serializers import USASerializer

class USAListView(mixins.CreateModelMixin, generics.ListAPIView):
    lookup_field = 'trackmanid'
    serializer_class = USASerializer

    def get_queryset(self):
        return Playerbios.objects.all()

    def perform_create(self, serializer):
        serializer.save(user=self.request.user)

    def post(self, request, *args, **kwargs):
        return self.create(request, *args, **kwargs)


class USAView(generics.RetrieveUpdateDestroyAPIView):
    lookup_field = 'trackmanid'
    serializer_class = USASerializer

    def get_queryset(self):
        return Playerbios.objects.all()

serializers.py

from rest_framework import serializers
from api.models import Playerbios

class USASerializer(serializers.ModelSerializer):
    class Meta:
        model = Playerbios
        fields = '__all__'
        lookup_field = 'trackmanid'

主要/ urls.py

from django.contrib import admin
from django.urls import path, include
from api.views import USAView, USAListView

urlpatterns = [
    path('admin/', admin.site.urls),
    path('api/bios/', include('api.urls')),
    path('api/bios/<trackmanid>/', include('api.urls')),
    path('accounts/', include('django.contrib.auth.urls')),
    path('', include('webapp.urls')),

]

API / urls.py

from django.conf.urls import url, include
from .views import USAView, USAListView

urlpatterns = [
    url('(?P<trackmanid>)/', USAView.as_view(), name='usa-rud-view'),
    url('', USAListView.as_view(), name='usa-list-view'),
]

Answer 1

您是否考虑过将Viewsets用于此API？ DRF具有强大的ViewSet，只需最少的配置即可执行所有这些功能。例如，这可以重写为：

<强> views.py

class USAViewset(ModelViewSet):
    queryset = Playerbios.objects.all()
    serializer_class = USASerializer
    lookup_field = 'trackmanid'

主要urls.py

urlpatterns = [
    ...
    path('api/bios/', include('api.urls')),
    ...    
]

<强> API / urls.py

urlpatterns = patterns(
    '',
)
router = DefaultRouter()
router.register(r'coupon', USAViewset)
urlpatterns += router.urls

DRF将完成其余的工作！在此处阅读更多内容：http://www.django-rest-framework.org/api-guide/viewsets/

Answer 2

我的猜测是你需要从主urls.py文件中删除这一行

path('api/bios/<trackmanid>/', include('api.urls'))

同时更改您的api/urls.py以包含正则表达式。格式为?P<name>[regex]。假设trackmanid是一个整数，则需要在其旁边加一个\d+正则表达式。

url('(?P<trackmanid>\d+)/', USAView.as_view(), name='usa-rud-view'),
