# Async adapter only works within the same process, so for manually triggering cable updates from a console,
# and seeing results in the browser, you must do so from the web console (running inside the dev process),
# not a terminal started via bin/rails console! Add "console" to any action or any ERB template view
# to make the web console appear.
