How do I use groups in Django Channels?

In Django Channels, groups allow you to send messages to multiple consumers at once. You can create a group using channel_layer.group_add() and send messages using channel_layer.group_send().

Can you give me an example of how to create a group?

Sure! First, you need to get the channel layer. Then, you can add a channel to a group like this: await channel_layer.group_add('my_group', self.channel_name).

How do I send a message to that group?

You can send a message using await channel_layer.group_send('my_group', {'type': 'chat.message', 'message': 'Hello, group!'}).

What if I want to receive messages from the group?

You need to define a method in your consumer to handle the messages, like async def chat_message(self, event): and then process the event data.
