How can I achieve this? Any example will be highly appreciated. -

Why is the consumer run twice when two users share the same websocket connection?
It's a one-to-one chat with message persistence. The issue is that when two users connect to the same chat, any message a user sends will be broadcast once but saved in the db twice. When only a single user is connected, however, it will work as normal--only save once. Help me figure out why the consumer is being run twice? Here is the relevant minimal code: class ChatConsumer(AsyncJsonWebsocketConsumer): ... async def receive_json(self, content): """ Called when we get a text frame. Channels will JSON-decode the payload for us and pass it as the first argument. """ # Messages will have a "command" key we can switch on command = content.get("command", None) recipient = content.get("recipient", None) sender = self.scope["user"] try: if command == "join": # Make them join the room await self.join_room(content["room"]) previous_message_list = await get_saved_messages(recipient, sender) for msg in previous_message_list: await self.send_json({ "msg_type": MSG_TYPE_MESSAGE, "room": content["room"], "username": msg.sender.user.username, "message": msg.message, },) elif command == "leave": # Leave the room await self.leave_room(content["room"]) elif command == "send": await self.send_room( content["room"], content["message"], content["recipient"] ) except ClientError as e: # Catch any errors and send it back await self.send_json({"error": e.code}) ... async def send_room(self, room_id, message, recipient): """ Called by receive_json when someone sends … -
Using Celery or Django-Background-Tasks on Openshift 3

Any way to group aggregations in Django?
We're currently using Django 1.8 and Postgres. I have an aggregation that I want to perform, but I want the aggregations grouped by month. This is trivial to do in SQL, but I can't seem to figure out any way to go about it with the Django ORM. Here's an example of the SQL query I'm performing that provides the desired results(SQL Fiddle): SELECT EXTRACT(month from date) as month, EXTRACT(year from date) as year, SUM(total) as total FROM transaction GROUP BY year, month ORDER BY year, month; And here's an example of my translation to Django(this one is using the Month class from this answer, but I've tried several variations): results = Transactions.all().annotate(month=Month('date')).aggregate(total=Sum('total', output_field=DecimalField())) There's some additional aggregating going on here, but I removed it for clarity. I don't care what the Django output would end up looking like as long as it's grouped by month. -
