Django-channels save reply channel to django model field?

[Nikoleta Misheva]

Hello, sorry to bother you but how do you make a django-channels  Channel field in a Django model? I tried to use ForeignKey and ForeignObject but doesn't do the work.

Thank you in advance :)

Hi,

Channel isn't a field type - it's a separate datastructure entirely from a database/Django models and is powered by its own code and servers (the channel layer).

If you want to persist the name of a reply_channel for use later, like knowing what channel connections are on to send information down, then use a CharField(max_length=255), and put the name of the channel in that (which is usually reply_channel.name). You can then take the string name and pass it to channel to make it again like Channel(reply_channel_name).

Hope that helps,

Andrew

So for example when I need the reply channel in the ws recieve method I need to create the Channel again and it will be the same channel referring to the same user? And do I have to delete the newly created channel after each ws recieve method?

Channels don't need to be deleted, they're just pointers. And yes, if you make a channel with the same name as a reply channel, it will function the same - all channels are, are strings put onto messages as a sort of header for routing and queuing purposes.
