向路由器或视图集添加更多视图 (Django-Rest-Framework)

本质上，我试图找到一种在不创建自定义路由器的情况下将更多视图附加到路由器的好方法。有什么好的方法可以实现这个目标呢？

这与我想要实现的目标相当。为了这个问题，变量名已经改变，我想介绍的示例方法也被极其简化。

Router:

router = routers.SimpleRouter(trailing_slash=False)
router.register(r'myobjects', MyObjectViewSet, base_name='myobjects')
urlpatterns = router.urls

ViewSet

class MyObjectsViewSet(viewsets.ViewSet):
""" Provides API Methods to manage MyObjects. """

def list(self, request):
    """ Returns a list of MyObjects. """
    data = get_list_of_myobjects()
    return Response(data)

def retrieve(self, request, pk):
    """ Returns a single MyObject. """
    data = fetch_my_object(pk)
    return Response(data)

def destroy(self, request, pk):
    """ Deletes a single MyObject. """
    fetch_my_object_and_delete(pk)
            return Response()

我需要包括另一种方法类型的一个示例。 （其中有很多）：

def get_locations(self, request):
    """ Returns a list of location objects somehow related to MyObject """
    locations = calculate_something()
    return Response(locations)

最终结果是以下 URL 可以正常工作并“干净”地实现。

GET example.com/myobjects/123/locations

The mariodev给出的答案 https://stackoverflow.com/a/18970651/3216056上面是正确的，只要你只想做GET要求。

如果你想POST对于要附加到 ViewSet 的函数，您需要使用action装饰器：

from rest_framework.decorators import action, link
from rest_framework.response import Response

class MyObjectsViewSet(viewsets.ViewSet):

    # For GET Requests
    @link()
    def get_locations(self, request):
        """ Returns a list of location objects somehow related to MyObject """
        locations = calculate_something()
        return Response(locations)

    # For POST Requests
    @action()
    def update_location(self, request, pk):
        """ Updates the object identified by the pk """
        location = self.get_object()
        location.field = update_location_field() # your custom code
        location.save()

        # ...create a serializer and return with updated data...

那么你会POST格式如下的 URL：/myobjects/123/update_location/
