Messages in Django Channels sent outside consumer not being received - django-channels

Question

I'm trying to send messages to specific websocket instances, but neither channel_layer.send, nor using channel_layer.group_send with unique groups for each instance seems to be working, no errors are being raised, they just aren't received by the instances.
The function that sends the message is:
def listRequest(auth_user, city):
request_country = city["country_name"]
request_city = city["city"]
request_location = request_city +", "+request_country
concatenate_service_email = auth_user.service + "-" + auth_user.email
this_request = LoginRequest(service_and_email=concatenate_service_email, location=request_location)
this_request.generate_challenge()
this_request.set_expiry(timezone.now() + timezone.timedelta(minutes=5))
this_request.save()
channel_layer = get_channel_layer()
print(auth_user.current_socket)
async_to_sync(channel_layer.group_send)(
auth_user.current_socket,{
"type": "new.request",
"service_and_email" : concatenate_service_email
},
)
My current working consumers.py (receive and scanrequest don't have anything that's likely to be relevant to the issue):
from asgiref.sync import async_to_sync
from channels.generic.websocket import WebsocketConsumer
from .helpers import verify_identity, unique_group
from django.utils import timezone
from .models import Authentication, LoginRequest
import json
import time
class AuthConsumer(WebsocketConsumer):
account_list =[]
def connect(self):
print("Connect attempted")
print(self.channel_name)
print(unique_group(self.channel_name))
async_to_sync(self.channel_layer.group_add)(unique_group(self.channel_name), self.channel_name)
self.accept()
def disconnect(self, close_code):
print("Disconnect attempted")
async_to_sync(self.channel_layer.group_discard)(unique_group(self.channel_name), self.channel_name)
for i in self.account_list:
serviceEmailSplit = i.split("-")
try:
auth_user = Authentication.objects.get(service=serviceEmailSplit[0],email=serviceEmailSplit[1])
auth_user.set_socket("NONE")
auth_user.save()
except:
print("Error user %s does not exist" %i)
pass
def receive(self, text_data):
print("Receiving data")
if text_data[0:7] == "APPROVE":
data_as_list = text_data.split(",")
serviceEmailSplit = data_as_list[1].split("-")
auth_user = Authentication.objects.get(service=serviceEmailSplit[0],email=serviceEmailSplit[1])
this_request = LoginRequest.objects.get(service_and_email=data_as_list[1],approved=False, expiry__gt=timezone.now())
if verify_identity(auth_user.public_key, data_as_list[2], this_request.challenge):
this_request.set_approved()
self.send("Request Approved!")
else:
self.send("ERROR: User verification failed")
else:
self.account_list = text_data.split(",")
self.account_list.pop(-1)
print(self.account_list)
for i in self.account_list:
serviceEmailSplit = i.split("-")
try:
auth_user = Authentication.objects.get(service=serviceEmailSplit[0],email=serviceEmailSplit[1])
auth_user.set_socket(unique_group(self.channel_name))
auth_user.save()
except:
self.send("Error user %s does not exist" %i)
self.scanRequest()
def scanRequest(self):
requestSet = LoginRequest.objects.filter(service_and_email__in = self.account_list, approved = False, request_expiry__gt = timezone.now())
if requestSet.count() > 0:
for request in requestSet:
self.send(request.service_and_email+","+request.location+","+str(request.challenge))
else:
self.send("NOREQUESTS")
def new_request(self,event):
print("NEW REQUEST!")
this_request = LoginRequest.objects.filter(service_and_email = event["service_and_email"]).latest('request_expiry')
self.send(this_request.service_and_email+","+this_request.location+","+str(this_request.challenge))
And my routing.py:
from django.urls import re_path
from . import consumers
from django.conf.urls import url
websocket_urlpatterns = [
url(r"^ws/$", consumers.AuthConsumer.as_asgi()),
]
"NEW REQUEST!" is never printed, having tried to call it both by sending a message directly, and neither does using groups like I have written above.
My redis server appears to be working from testing like the documentation for the channels tutorial suggests:
https://channels.readthedocs.io/en/stable/tutorial/part_2.html
I'm pretty stumped after attempts to fix it, and I've looked at the other posts on stackoverflow with the same/similar issues and I'm already following whatever solutions they have in my code.
