Arguments: receiver A function or an instance method which is to receive signals. Receivers must be hashable objects. If weak is True, then receiver must be weak referenceable. Receivers must be able to accept keyword arguments. If a receiver is connected with a dispatch_uid argument, it will not be added if another receiver was already connected with that dispatch_uid. sender The sender to which the receiver should respond. Must either be a Python object, or None to receive events from any sender. weak Whether to use weak references to the receiver. By default, the module will attempt to use weak references to the receiver objects. If this parameter is false, then strong references will be used. dispatch_uid An identifier used to uniquely identify a particular instance of a receiver. This will usually be a string, though it may be anything hashable. i(tsettingss"Signal receivers must be callable.s:Signal receivers must accept keyword arguments (**kwargs).RRN(t django.confRt configuredtDEBUGtcallabletAssertionErrorRt ValueErrorR RtrefRRRRtPY3tfinalizet_remove_receiverRt_clear_dead_receiversR tappendRtclear( Rtreceivertsendertweakt dispatch_uidRt lookup_keyR"treceiver_objecttr_keyt_((s>/usr/lib/python2.7/site-packages/django/dispatch/dispatcher.pytconnect;s2!        c Cs|dk r%tjdtddn|r@|t|f}nt|t|f}t}|jo|jxPtt |j D]9}|j |\}} ||krt }|j |=PqqW|j j WdQX|S(s Disconnect receiver from sender for signal.

If any receiver raises an error (specifically any subclass of Exception), the error instance is returned as the result for that receiver.
