将更多视图添加到路由器或视图（Django-Rest-Framework） [英] Adding more views to a Router or viewset (Django-Rest-Framework)

问题描述

基本上，我试图找到一个很好的方式来附加更多的视图到路由器，而不创建自定义路由器。 这是一个很好的方法来实现这一点？

Essentially, I'm trying to find a good way to attach more views to a Router without creating a custom Router. What's a good way to accomplish this?

这是一些与我要完成的工作相当的东西。变量名称已经更改，为了这个问题，我想介绍的示例方法极其简化。

Here is something sort of equivalent to what I'm trying to accomplish. Variable names have been changed and the example method I want to introduce is extremely simplified for the sake of this question.

路由器：

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()

我需要包括的另一种方法类型的一个例子。 （其中有很多）：

One example of another method type I need to include. (There are many of these):

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可以正常工作并被干净地实现。

The end-result is that the following URL would work correctly and be implemented 'cleanly'.

GET example.com/myobjects/123/locations

推荐答案

由mariodev给出的答案是正确的，只要你只想使 GET 请求。

The answer given by mariodev above is correct, as long as you're only looking to make GET requests.

如果要将 POST 添加到要附加到的ViewSet，您需要从rest_framework中使用操作装饰器：

If you want to POST to a function you're appending to a ViewSet, you need to use the action decorator:

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...

然后你将 POST 到一个格式如下的URL：
/ myobjects / 123 / update_location /

Then you would POST to a URL formatted like: /myobjects/123/update_location/
