在DRF中嵌套ViewSet路由

Question

我已经创建了2个这样的ModelViewSets(简化为演示):

class SomeBaseViewSet(viewsets.ReadOnlyModelViewSet):
    serializer_class = SomeEventSerializer
    permission_classes = (permissions.IsAuthenticated,)

    def get_queryset(self):
        return SomeObjects.objects.filter(owner=self.request.user)

    def get_serializer_context(self):
        context = super(SomeBaseViewSet, self).get_serializer_context()
        context.update({
            "user": self.request.user,
            "some_context_key": False
        })
        return context

class AdminViewSet(SomeBaseViewSet):
    # Added in the HasAdminPermission
    permission_classes = (permissions.IsAuthenticated, HasAdminPermission)

    # Different queryset filter (overriding `get_queryset` vs setting queryset for standardization)
    def get_queryset(self):
        return SomeObjects.objects.all()

    # The context should have `some_context_key=True`, and `user=request.user`
    def get_serializer_context(self):
        context = super(AdminViewSet, self).get_serializer_context()
        context.update({
            "some_context_key": True
        })
        return context

我的路由器/ url配置看起来像这样

router = DefaultRouter()

router.register(r'some_view', SomeBaseViewSet, base_name="some_view")

urlpatterns += [
    url(r'^api/', include(router.urls)),
]

如果我想要路由/api/some_view/admin到AdminViewSet,那么最好的方法是什么？

我试过的事情:

• @list_route在SomeBaseViewSet,但无法弄清楚将它连接到我的"正确"方式AdminViewSet
• 添加url(r'^api/some_view/admin$', AdminViewSet.as_view({"get": "list"}))到我的urlpatterns(哪个sorta有效,但是ViewSet稍微有点,并且通常真的是手动的):
• 有一个专门DefaultRouter用于some_view视图集,我然后登上url(r'^api/some_view/')- 再次hacky和迂腐与大量的路线

是否有"正确"的方式来完成我想要完成的任务,或者我应该找到针对此问题的不同解决方案(即过滤器或其他内容)？

我见过像https://github.com/alanjds/drf-nested-routers这样的库,但这对我(相当简单)的需求来说似乎有些过分.

Answer 1

不确定我是否错过了一些东西，但我刚刚测试过，效果很好（顺序很重要）：

router = DefaultRouter()
# this will overrides routes from the line below
router.register(r'some_view/admin', AdminViewSet) 
router.register(r'some_view', SomeBaseViewSet)

Answer 2

我想我已经找到了自己问题的答案，但我对此设置了 +50 代表赏金，​​以防有人想插话（也许是@tom-christie？）。

不管怎样，我为我的用例解决这个问题的方法是使用@list_routeand theAdminViewSet函数.as_view()。

像这样的东西就足够了：

class SomeBaseViewSet(viewsets.ReadOnlyModelViewSet):
    serializer_class = SomeEventSerializer
    permission_classes = (permissions.IsAuthenticated,)

    def get_queryset(self):
        return SomeObjects.objects.filter(owner=self.request.user)

    def get_serializer_context(self):
        context = super(SomeBaseViewSet, self).get_serializer_context()
        context.update({
            "user": self.request.user,
            "some_context_key": False
        })
        return context

    @list_route()
    def admin(self, request):
        return AdminViewSet.as_view({"get": "list"})(request)

class AdminViewSet(SomeBaseViewSet):
    # Added in the HasAdminPermission
    permission_classes = (permissions.IsAuthenticated, HasAdminPermission)

    # Different queryset filter (overriding `get_queryset` vs setting queryset for standardization)
    def get_queryset(self):
        return SomeObjects.objects.all()

    # The context should have `some_context_key=True`, and `user=request.user`
    def get_serializer_context(self):
        context = super(AdminViewSet, self).get_serializer_context()
        context.update({
            "some_context_key": True
        })
        return context

并且将允许人们相应地路由 url（基于函数的名称），并强制执行您需要的任何额外功能。
