如何在Django REST框架中实现资源的层次结构（例如/parents/<；id>；/children）

我在Django REST Framework网站的教程中找不到关于如何实现这一点的任何信息，我也没有在文档中找到它，尽管我确信它在某个地方

我希望

issues

作为父资源，

pages

作为子资源，以便

/issues/1/pages

返回

issue\u id

为1的所有页面

使用基于类的通用视图是否有一个很好的方法来实现这一点

这是我到目前为止所拥有的

    def get_queryset(self):
        customer_pk = self.kwargs['customer_pk']
        return self.queryset.filter(customer__pk=customer_pk)

    def pre_save(self, obj):
        obj.customer_id = self.kwargs['customer_pk'] 

class OrderDetail(generics.RetrieveUpdateDestroyAPIView):
    queryset = Order.objects.all()
    serializer_class = OrderSerializer

from models import Customer, Order

from rest_framework import serializers
from rest_framework.reverse import reverse

class OrderSerializer(serializers.HyperlinkedModelSerializer)

    class Meta:
        model = Order

class CustomerSerializer(serializers.HyperlinkedModelSerializer)

    orders = serializers.SerializerMethodField('get_customer_orders')

    def get_customer_orders(self, obj):
        return reverse('ordersbycustomer-list', 
               args=[obj.pk], request=self.context['request'])

    class Meta:
        model = Customer

from django.conf.urls import patterns, include, url
from views import OrdersByCustomer, CustomerDetail, CustomerList

urlpatterns = patterns("",
    url(r'^customers/(?P<customer_pk>.+)/orders/$', OrdersByCustomer.as_view(), name='ordersbycustomer-list'),
    url(r'^customers/(?P<pk>.+)/$', CustomerDetail.as_view(), name='customer-detail'),
    url(r'^customers/$', CustomerList.as_view(), name='customer-list'),
    )

现在，“order/id/lines”将返回与该id标识的订单有关系的序列化订单行列表

当您向路由器注册视图时，用@link或@action修饰的视图集上的任何方法都将获得一个URL。

以下是我完成此操作的另一种方法：

视图.py

    lines = serializers.HyperlinkedIdentityField(view_name='order-lines')

class OrderLineSerializer(serializers.HyperlinkedModelSerializer):

    class Meta:
        model = OrderLine

from views import OrderViewSet, OrderLineViewSet
from rest_framework.routers import DefaultRouter

router = DefaultRouter()
router.register(r'order', OrderViewSet)
router.register(r'orderline', OrderLineViewSet)
urlpatterns = router.urls

from models import Customer, Order
from serializers import CustomerSerializer, OrderSerializer

from rest_framework import generics

class CustomerList(generics.ListCreateAPIView):
    queryset = Customer.objects.all()
    serializer_class = CustomerSerializer

class CustomerDetail(generics.RetrieveUpdateDestroyAPIView)
    queryset = Customer.objects.all()
    serializer_class = CustomerSerializer

class OrdersByCustomer(generics.ListCreateAPIView):
    queryset = Order.objects.all()
    serializer_class = OrderSerializer

    def get_queryset(self):
        customer_pk = self.kwargs['customer_pk']
        return self.queryset.filter(customer__pk=customer_pk)

    def pre_save(self, obj):
        obj.customer_id = self.kwargs['customer_pk'] 

class OrderDetail(generics.RetrieveUpdateDestroyAPIView):
    queryset = Order.objects.all()
    serializer_class = OrderSerializer

从django.conf.url导入模式，包括，url
从视图导入订单ByCustomer、CustomerDetail、CustomerList
urlpatterns=模式（“”，
url（r“^customers/（？P.+）/orders/$”，OrdersByCustomer.as_view（），name='OrdersByCustomer-list'），
url（r“^customers/（？P.+）/$”，CustomerDetail.as_view（），name='customer-detail'），
url（r“^customers/$”，CustomerList.as_view（），name='customer-list'），
)

与视图集/路由器相比，涉及的代码更多，但这使您能够更有效地控制正在发生的事情

在这里，我选择仅将订单作为客户的子项公开。因为它们是分开的，所以可以对列表和详细信息使用不同的序列化程序类

我将def get_queryset（self）：issue_id=self.kwargs['issue_id']return Page.objects.filter（issue_id=issue_id）添加到页面列表中，现在可以获取问题的工作/ /页数。现在我还得想办法发帖子

我在页面列表中添加了def pre_save（self，obj）：obj.issue_id=self.kwargs['issue_id']，现在POST也可以了。从不存在的问题查询页面将返回空结果，而不是404 not found。如果有人知道更好的方法，我很想听听

如果您的方法get_queryset（self）返回的是一个空列表，而不是404 NOT FOUND，我建议您使用快捷方式函数get_list_或django的_404。 该方法可以如下所示：

from django.shortcuts import get_list_or_404

def get_queryset(self):
    filter = {}
    filter['issue_id'] = self.kwargs['issue_id']
    return get_list_or_404(self.queryset, **filter)

---

我知道这是一篇老文章，但也许这可以帮助其他有相同或类似问题的人。

我添加了

def get\u queryset（self）：issue\u id=self.kwargs['issue\u id']return Page.objects.filter（issue\u id=issue\u id）

到

页面列表

，现在为

问题//pages。现在我只需要弄清楚如何发布。我将
def pre_save（self，obj）：obj.issue_id=self.kwargs['issue_id']
添加到
PageList
中，现在发布也可以了。从不存在的问题查询页面将返回空结果，而不是404 not found。如果有人知道一个更好的方法来做这件事，我很有兴趣听到它。谢谢你的干净的例子。但是，我还希望子资源的POST位于parents//children下，并且我希望子资源只能在其父母下访问，因此children/甚至不应该是有效的路径。我想，通过使用@action修饰的方法可能可以修复发布，但与基于类的视图相比，它似乎没有多大优势。不过我真的很喜欢路由器的想法。在进一步研究之后，我认为使用视图集和路由器既方便又简单，但仍然需要大量定制，才能让它们实现父子关系之类的功能。我将在另一个答案中发布另一个更明确的方法，我一直在这样做。当使用ViewSet和@link的这种分层资源技术时，您是否找到了一种方法来更改在跟随@link时可浏览API顶部显示的docstring？实际上，它似乎显示了父级（订单）而不是子级（订单行）的帮助。如果您将pre_save添加到OrdersByCustomer，类似于我在原始问题的答案中所写的，我将使其成为可接受的答案。
