Rails 3 initializers that run only on `rails server` and not `rails generate`, etc

Question

I have a relatively small piece of initializer code that I want to run whenever rails server runs, but not when I run rails generate, rails

Answer 1

Can you do something like overriding Rails::Server#initializeso that it invokes your initialization code in your initializer?

Or, more easily, just put your code in script/rails, as that will be run everytime you run rails server, you can easily fiddle with ARGV or ENV in there.

Answer 2

Here's one way:

# config/initializers/my_init.rb
Rails.application.config.after_initialize do
    # tweak this as required...
    unless defined?(::Rails::Generators) || defined?(::Rails::Console) || File.basename($0) =='rake'
        Rails.logger.info("Doing some init")
        # ...
    end
end
