more.signals
more.signals is an extension for Morepath that adds Blinker signals support.
Quickstart
The integration adds two directives to a Morepath App for connecting and disconnecting signals. Once connected you can emit to signal using request.app.signal('signal.name') to specify a named signal and then use the send() method, or you can combine both using request.app.signal('signal.name').send(self, **data). Please read Blinker's documentation for all the details.
from more.signals import SignalApp
class App(SignalApp):
pass
@App.connect('hello')
def say_hello(sender, **data):
print('HELLO {}!'.format(data.get('name')))
@App.path(path='')
class Root(object):
pass
@App.json(model=Root)
def root_view(self, request):
name = 'Foo Bar'
request.app.signal('hello').send(self, name=name)
return {'name': name}
if __name__ == '__main__':
morepath.run(App())
