PermissionRequiredMixin¶ class guardian.mixins.PermissionRequiredMixin¶. A view mixin that verifies if the current logged in user has the specified permission by wrapping the request.user.has_perm(..) method.. If a get_object() method is defined either manually or by including another mixin (for example SingleObjectMixin) or self.object is defined then the permission will be tested against Multiple inheritance and mixin classes in Python.
