Question

How do I tell if rails is running under a web server, as opposed to a script or irb?

For context: I’m tracking an ActiveRecord object, and I want to email alerts if the objects changes, but only if the changes came through the web interface.

Answer 1

I’ve found something that works, though it’s not very pretty

$0  # => "irb" (for script/console) 
    # => "/some/handler.fcgi" (for webserver)
    # => "/some/script.rb" (for a script)
