Error: TypeError: signal.__init__() got an unexpected keyword argument ‘providing_args’
Explanation: This error occurs when trying to initialize a signal with an unexpected keyword argument ‘providing_args’.
Examples:
from django.dispatch import Signal
# Define a custom signal
my_signal = Signal(providing_args=['data'])
# Connect a receiver to the signal
def my_receiver(sender, **kwargs):
data = kwargs.get('data')
print('Received data:', data)
my_signal.connect(my_receiver)
# Send the signal
data = 'Hello world!'
my_signal.send(sender=None, data=data)
In the above example, we define a custom signal “my_signal” that takes an argument ‘data’. We then connect a receiver function “my_receiver” to the signal, which simply prints the received data. Finally, we send the signal with some data and the receiver function gets called.
