Signals usage incompatible with Django 4

[rmartin48]

Summary

Attempting to use drf_model_pusher with Django 4 raises the following exception on startup:

File "/app/.venv/lib/python3.9/site-packages/drf_model_pusher/signals.py", line 4, in <module>
    view_post_save = Signal(
TypeError: __init__() got an unexpected keyword argument 'providing_args'

Django 3.1 deprecated the providing_args kwarg from Signal:

The purely documentational providing_args argument for Signal is deprecated. If you rely on this argument as documentation, you can move the text to a code comment or docstring.

Django 4 has now completely removed this kwarg and raises a TypeError if it is provided.

Proposed Solution

Considering providing_args was only for documentation purposes, we can simply refactor signals.py from:

from django.dispatch import Signal


view_post_save = Signal(
    providing_args=["instance", "channels", "event_name", "data", "socket_id"]
)

view_pre_destroy = Signal(
    providing_args=["instance", "channels", "event_name", "data", "socket_id"]
)

to

from django.dispatch import Signal


view_post_save = Signal()

view_pre_destroy = Signal()
