# If you need to disconnect a given connection, you can go through the

# RemoteConnections. You can find the connections you're looking for by
|
|
# searching for the identifier declared on the connection. For example:
|
|
#
|
|
# module ApplicationCable
|
|
# class Connection < ActionCable::Connection::Base
|
|
# identified_by :current_user
|
|
# ....

# ActionCable.server.remote_connections.where(current_user: User.find(1)).disconnect

# This will disconnect all the connections established for
|
|
# <tt>User.find(1)</tt>, across all servers running on all machines, because
|
|
# it uses the internal channel that all of these servers are subscribed to.
