Sure, here's the decorated method from v2.py:
class MetersController(rest.RestController):
"""Works on meters."""
@pecan.expose()
def _lookup(self, meter_name, *remainder):
return MeterController(meter_name), remainder
@wsme_pecan.wsexpose([Meter], [Query])
@secure(RBACController.check_permissions)
def get_all(self, q=None):
and here's the decorator called by the secure tag:
class RBACController(object):
global _ENFORCER
if not _ENFORCER:
_ENFORCER = policy.Enforcer()
@classmethod
def check_permissions(cls):
# do some stuff
In check_permissions I'd like to know the class and method with the @secure tag
that caused check_permissions to be invoked. In this case, that would be
MetersController.get_all.
Thanks
