我不能让@detail_route像我想的那样工作。

我有两个API调用要处理：

/movie/
/movie/highlight

我正在尝试使用@detail_route在视图集中拾取/movie/突出显示url。

我的urls.py看起来是这样的：

from django.conf.urls import url, include
from rest_framework import routers
from api import views

router = routers.DefaultRouter()
router.register(r'users', views.UsersViewSet)	
router.register(r'groups', views.GroupViewSet)	
router.register(r'movie', views.MovieViewSet)

我的views.py看起来是这样的：

rom django.contrib.auth.models import User, Group
from movies.models import Movie

from api.serializers import UserSerializer, GroupSerializer, MovieSerializer

from rest_framework.response import Response
from rest_framework import permissions
from rest_framework import renderers
from rest_framework import viewsets
from rest_framework.decorators import detail_route

# Code from DRF quickstart tutorial
class UsersViewSet(viewsets.ModelViewSet):
    """
    API endpoint that allows users to be viewed or edited.
    """
    queryset = User.objects.all().order_by('-date_joined')
    serializer_class = UserSerializer

# Code from DRF quickstart tutorial
class GroupViewSet(viewsets.ModelViewSet):
    """
    API endpoint that allows groups to be viewed or edited.
    """
    queryset = Group.objects.all()
    serializer_class = GroupSerializer

# MY CODE
class MovieViewSet(viewsets.ModelViewSet):
    """
    API endpoint that allows groups to be viewed or edited.
    """
    queryset = Movie.objects.all().order_by('-title')
    serializer_class = MovieSerializer

    @detail_route(renderer_classes=(renderers.StaticHTMLRenderer,))
    def highlight(self, request, *args, **kwargs):
        snippet = "Highlight"
        return Response(snippet)

serializers.py看起来如下所示：

from django.contrib.auth.models import User, Group
from movies.models import *
from rest_framework import serializers

class UserSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = User
        fields = ('url', 'username', 'email', 'groups')


class GroupSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = Group
        fields = ('url', 'name')

# My code...
class MovieSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = Movie
        fields = ('title', 'details')

如果我尝试/育婴/ url调用，它就会像预期的那样工作。如果我尝试/育人/高亮/调用，我会得到一个404错误。

我是DRF的新手，所以怀疑我正在做一些非常愚蠢的事情，但无法从我扫描过的各种文档和教程中找到什么。

您需要使用@list_route @detail_route 装饰器而不是@detail_route装饰器。

这将生成url movie/highlight/。

使用@list_route修饰方法生成{prefix}/{methodname}/类型的url，而detail_route修饰方法生成{prefix}/{lookup}/{methodname}/类型的url。这里，methodname是方法的名称，lookup是执行查找的查找值，用于获取对象的详细视图。

class MovieViewSet(viewsets.ModelViewSet):
    """
    API endpoint that allows groups to be viewed or edited.
    """
    queryset = Movie.objects.all().order_by('-title')
    serializer_class = MovieSerializer

    # use list_route decorator
    @list_route(renderer_classes=(renderers.StaticHTMLRenderer,))
    def highlight(self, request, *args, **kwargs):
        snippet = "Highlight"
        return Response(snippet)
