Compare with:

stream_for(model, callback = nil, coder: nil, &block)

Start streaming the pubsub queue for the model in this channel. Optionally, you can pass a callback that’ll be used instead of the default of just transmitting the updates straight to the subscriber.

Pass coder: ActiveSupport::JSON to decode messages as JSON before passing to the callback. Defaults to coder: nil which does no decoding, passes raw messages.

Parameters

model req
callback opt = nil
coder key = nil
block block
