permission to class some fields of ViewSet method Django rest framework

Question

I want AllowAny permission only for the retrieve function. In my ViewSets.

class PostLanguageViewSet(viewsets.ViewSet):

    permission_classes = (permissions.AllowAny,)

    permission_classes_per_method = {
        "retrieve": permission_classes
    }

    def retrieve(self, request, post_id=None, post_language_id=None, *args, **kwargs):
    ...

    def destroy(self, request, post_id=None, post_language_id=None, *args, **kwargs):
    ...

    def update(self, request, post_id=None, post_language_id=None, *args, **kwargs):
    ...

• this method allows all function permission AllowAny.

try this

class PostLanguageViewSet(viewsets.ViewSet):
    def get_permissions(self):
        if self.request.method == 'GET':
            return [permissions.AllowAny()]
        else:
            return super().get_permissions()
