ViewSets are essentially just a type of class based view, that doesn't provide
any method handlers, such as `get()`, `post()`, etc... but instead has actions,
such as `list()`, `retrieve()`, `create()`, etc...

Actions are only bound to methods at the point of instantiating the views.

    user_list = UserViewSet.as_view({'get': 'list'})
    user_detail = UserViewSet.as_view({'get': 'retrieve'})

Typically, rather than instantiate views from viewsets directly, you'll
register the viewset with a router and let the URL conf be determined
automatically.

    router = DefaultRouter()
    router.register(r'users', UserViewSet, 'user')
    urlpatterns = router.urls

    This is the magic.

    Overrides `.as_view()` so that it takes an `actions` keyword that performs
    the binding of HTTP methods to actions on the Resource.

    For example, to create a concrete view binding the 'GET' and 'POST' methods
    to the 'list' and 'create' actions...

    view = MyViewSet.as_view({'get': 'list', 'post': 'create'})

        Because of the way class based views create a closure around the
        instantiated view, we need to totally reimplement `.as_view`,
        and slightly modify the view function that is created and returned.
        NzwThe `actions` argument must be provided when calling `.as_view()` on a ViewSet. For example `.as_view({'get': 'list'})`zUYou tried to pass in the %s method name as a keyword argument to %s(). Don't do that.z#%s() received an invalid keyword %rnamesuffixzO%s() received both `name` and `suffix`, which are mutually exclusive arguments.c                    s   di } |_   D ]\}}t||}t||| qt|dr,t|ds,|j|_| |_||_||_	|j
