Question

Rails 3.0, to the extent it matters.

So, ordinarily in development mode, logger messages end up written to
both development.log AND console, if you’re in an interactive console.

Which is just spiffy, fine.

But something I can’t figure out, if I write a logger message during the
boot process (say in config.after_initialize), then this does NOT
happen. The log message is in the log/development.log file, but NOT
written to console. Which is annoying, the reason I’m writing something
out during the boot process (echo’ing certain config) is for the
developer to see it, because it aids in debugging.

Anyone have any idea what’s going on here, and if there’s anything I can
do about it?

Answer 1

All you need to do is to add a print statement before your logger call, eg:

config.after_initialize do
  print Rails.logger.info("Testing")
end

The Rails console won’t automatically display anything while it’s initializing, but it will display anything you pass it with a print statement. Rails.logger returns the value it writes to the log, so it really is as simple as this.
