Django Rest框架中带APIViews的嵌套路由

nested api rest django python

Ð.Ð. · 技术社区 · 8 年前

Profiles Albums , Images , Comments , Likes .

我试图通过以下方式访问资源: api/v1/profiles/1/albums --&燃气轮机;从个人资料中获取id为1的所有相册

ViewSet 而是使用了 APIView 我想用它(我真的是新手,我甚至不知道我能用它吗用于CRUID操作)。我已尝试实现以下内容:

还有很多其他的,但我不能让它工作。。。

如果有一些详细的教程,请参考它,我真的需要很快完成这一点。

谢谢大家!

我用 get_queryset 和 get_object . 其他寻求帮助的人有一个完整的例子:

URL。py公司 :

url(r'(?P<profile_id>\d+)/albums/(?P<album_id>\d+)/images/(?P<image_id>\d+)/comments/(?P<comment_id>\d+)/?$',CommentDetailAPIView.as_view(), name='profile-album-image-comment'),

在里面 意见。py公司 :

class GetCommentsAPI(ListAPIView):
"""

"""
serializer_class = CommentSerializer
filter_backends = [SearchFilter]  # this must be array!
authentication_classes = [AllowAny]

def get_queryset(self, *args, **kwargs):
   # ipdb.set_trace(context=5)
    profile_id = self.kwargs.get("profile_id")
    if not profile_id:
        return Response({"status": "fail"}, status=403)

    profile = Profile.objects.get(pk=profile_id)

    album_id = self.kwargs.get("album_id")
    if not album_id:
        return Response({"status": "fail"}, status=403)
    album = Album.objects.get(pk=album_id, owner_id=profile_id)

    if not album:
        return Response({"status": "fail"}, status=404)

    image_id = self.kwargs.get("image_id")
    if not image_id:
        return Response({"status": "fail"}, status=403)
    image = Image.objects.get(pk=image_id, album_id=album_id)

    queryset_list = Comment.objects.filter(image__pk=image_id)
    return queryset_list

class CommentDetailAPIView(DestroyModelMixin, UpdateModelMixin, RetrieveAPIView):
"""

"""
queryset = Comment.objects.all()
serializer_class = DetailedCommentSerializer
permission_classes = [IsAuthenticatedOrReadOnly]

def get_object(self):
    profile_id = self.kwargs.get("profile_id")
    profile = Profile.objects.get(pk=profile_id)
    if not profile:
        return JsonResponse({"status":"fail","code":404})

    album_id = self.kwargs.get("album_id")
    album = Album.objects.get(pk=album_id)
    if not album:
        return JsonResponse({"status": "fail", "code": 404})

    image_id = self.kwargs.get("image_id")
    image = Image.objects.get(pk=image_id)
    if not image:
        return JsonResponse({"status": "fail", "code": 404})

    comment_id = self.kwargs.get("comment_id")
    if not comment_id:
        return JsonResponse({"status": "fail", "code": 404})

    comment = get_object_or_404(queryset=Comment.objects.all(), pk=comment_id, image__pk=image_id)
    return comment

def put(self, request, *args, **kwargs):
    return self.update(request, *args, **kwargs)

def delete(self, request, *args, **kwargs):
    return self.destroy(request, *args, **kwargs)

也许你需要 extra-link-and-actions ,例如:

from rest_framework.decorators import detail_route

class ProfileView
    # Your Code Here

    @detail_route(methods=['GET'])
    def albums(request, pk=None):
        # Heed to change related name 'albums_set'
        qs = self.get_object().albums_set.all()
        serializer = AlbumsSerializer(qs, many=True)
        return Response(serializer.data)
