Django-channels request depending Middleware

Hey everybody,

We are using a Middleware to inject postgresql schemas into queries based on a subdomain. You can have a look how it's done here:

https://github.com/systori/systori/blob/dev/systori/apps/company/middleware.py

Now, for channels I've noticed that there is no usual request, right?

So, if I'm connecting a WS it doesn't hit the Middleware. 

Are there any guides or docs available or any recommendations how to solve this properly for channels?

Thx,

Marius
