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 )update_wrapper) getmembers)NoReverseMatch)classonlymethod) csrf_exempt)genericsmixinsviews) MethodMapper)reversecCst|do t|jtS)Nmapping)hasattr isinstancer r )attrrP/var/www/html/loop/nvenv/lib/python3.10/site-packages/rest_framework/viewsets.py_is_extra_actionsrcCs |j|ksJdj||d|S)NzExpected function (`{func.__name__}`) to match its attribute name (`{name}`).

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