Currently, the only prints that are not outputting are the ones in the frNotifier, heres settings.py: ```python CHANNEL_LAYERS = { "default": { "BACKEND": "channels.layers.InMemoryChannelLayer" } } ASGI_APPLICATION = 'app_dependencies.asgi.application' ``` consumers.py: ```python from channels.generic.websocket import WebsocketConsumer from asgiref.sync import async_to_sync from api.models import friendRequest from api.models import User import json class FRConsumer(WebsocketConsumer): def connect(self): if self.scope["user"].is_anonymous: # Reject the connection self.close() else: # Accept the connection user = self.scope['user'] self.group_name = f'noti_{user.userID}' async_to_sync(self.channel_layer.group_add(self.group_name, self.channel_name)) self.accept() def disconnect(self, close_code): async_to_sync(self.channel_layer.group_discard(self.group_name, self.channel_name)) def receive(self, text_data): print(f"{text_data}") jData = json.loads(text_data) reqID = jData["requestID"] receiverUserID = friendRequest.objects.filter(requestID=reqID).values("receiver")[0]["receiver"] senderUserID = friendRequest.objects.filter(requestID=reqID).values("sender")[0]["sender"] sender = User.objects.filter(userID=senderUserID).values("username")[0]["username"] targetGrp = f'noti_{receiverUserID}' receiver = User.objects.filter(userID=receiverUserID).values("username")[0]["username"] # Truth table variables print(f"""------------- TRUTH TABLE ------------- Target Group: {targetGrp} Receiver: {receiver} Sender: {sender} Own Group Name: {self.group_name} ---------------- OUTPUTS ---------------""") try: print("Sending to..." + targetGrp) async_to_sync( self.channel_layer.group_send)( targetGrp, { 'type': 'frNotifier', 'requestID': reqID, 'sender': sender } ) print("Succesfully sent message to group") except Exception: print("User not online") def frNotifier(self, textData): print("FRNotifier called") try: reqID = textData['requestID'] sender = textData['sender'] async_to_sync(self.send(textData=json.dumps({ 'requestID':reqID, 'senderUsername': sender }))) print("Friend request notification sent") except Exception as e: print("ERROR: User is not online for FR notification.") ``` My issue is that frNotifier is not being called on the receiving consumer’s/group’s end. ---

How are you running your project? > [@B4sic101](#): > > ` "BACKEND": "channels.layers.InMemoryChannelLayer"` This is a really bad idea once you get beyond the stage of prototyping. ---

To my knowledge I am only to use redis when I deploy the application not during prototyping. Not sure what the proper way is, I’m still quite a beginner - my bad. But I am running my project on localhost. ---

I’m not saying that this is the cause of this issue - only that it’s something that should be addressed sooner rather than later. ---

Well the WebSocket handshakes are completed and the outputs look like this: ```python {"requestID":"5361f63d-c921-4043-9990-853dfc65e77b"} ------------- TRUTH TABLE ------------- Target Group: noti_16bb0918-aa22-44e3-8864-8b639a915190 Receiver: Frank Sender: Jerry Kole Own Group Name: noti_3f1e0afe-64ac-4ce4-b5e3-dd5cb4b4555e ---------------- OUTPUTS --------------- Sending to...noti_16bb0918-aa22-44e3-8864-8b639a915190 Succesfully sent message to group ``` It just blacks out after the receive outputs and no output is given for the frNotifier. ---

Not sure how to check that with InMemoryChannelLayer. Would I have to create a model to keep track of this? ---

You could print the users as they connect - and as long as there’s no disconnect message, that user should remain connected. ---
