Django DRF - 通过权限限制对列表视图的访问

Question

我有一个 DRF ViewSet，我正在向其中添加CanViewAndEditStaff权限。我只希望某些用户 ( user.access_level < 2) 能够查看员工列表。在我的权限类中，如何区分对list视图的调用和对get项目视图的调用。这是我的权限类：

class CanViewAndEditStaff(permissions.BasePermission):

        def has_permission(self, request, view):

            # IF THIS IS A LIST VIEW, CHECK ACCESS LEVEL
            if ( request.user.access_level < 3 ):
                return True

            # ELSE, CONTINUE ON TO OBJECT PERMISSIONS

        def has_object_permission(self,request,view,account):

            # admin can do anything
            if ( request.user.access_level == 1 ):
                return True

            # view/edit/delete
            else:

                # users can view their own account
                if  account == request.user:
                    return True

                elif account.access_level >= request.user.access_level:
                    return True

            return False

Answer 1

class CanViewAndEditStaff(permissions.BasePermission):

    def has_permission(self, request, view):

        # IF THIS IS A LIST VIEW, CHECK ACCESS LEVEL
        if (view.action == 'list' and request.user.access_level < 3 ):
            return True

        # ELSE, CONTINUE ON TO OBJECT PERMISSIONS

您可以使用 view.action 来了解这是列表还是其他内容。
