== Using with Phusion Passenger
|
||||
|
||||
When passenger is in smart spawning mode you need to be sure that child
|
||||
processes forked by passenger will create a new connection to the database.
|
||||
activerecord-mongo-adapter handles this for you, so if you are using that
|
||||
you shouldn't need to worry about it. Otherwise you'll either need to use
|
||||
conservative spawning[http://www.modrails.org/documentation/Users%20guide.html#RailsSpawnMethod]
|
||||
or handle reconnecting when passenger forks a new process:
|
||||
|
||||
if defined?(PhusionPassenger)
|
||||
PhusionPassenger.on_event(:starting_worker_process) do |forked|
|
||||
if forked
|
||||
# Call db.connect_to_master to reconnect here
|
||||
end
|
||||
end
|
||||
end
|
||||
|
||||
The above code should be put in _environment.rb_ or an initialization
|
||||
script.
