SignalHook¶
reviewboard.extensions.hooks.SignalHook allows extensions to
easily connect to signals without worrying about
manually disconnecting when the extension is disabled.
To connect to a signal, the extension needs to instantiate
SignalHook and pass in the signal to connect to, the callback
function, and an optional sender.
Example¶
import logging
from reviewboard.extensions.base import Extension
from reviewboard.extensions.hooks import SignalHook
from reviewboard.reviews.signals import review_request_published
class SampleExtension(Extension):
def initialize(self):
SignalHook(self, review_request_published, self.on_published)
def on_published(self, review_request=None, **kwargs):
logging.info('Review request %s was published!',
review_request.display_id)
