Is there any callback/hook for me to add some code to be called after  
all initializers (config/initializers/\*) are called, in Rails 2?

Or should I count on initializers being run in sort order and add one  
called zzzz\_after\_all\_initializers.rb or something?

Any advice?

Jonathan

config.after\_initialize do  
…  
end

Thanks Frederick. But, documentation and googling that led me to source  
suggests that the after\_initialize hook is called _before_  
config/initializers are.

[http://dev.rubyonrails.org/browser/tags/rel\_2-0-0\_RC1/railties/lib/initializer.rb#L340](http://dev.rubyonrails.org/browser/tags/rel_2-0-0_RC1/railties/lib/initializer.rb#L340)

114 after\_initialize  
115  
116 load\_application\_initializers

Although I guess I’m looking at 2.0RC1 there. Not familiar enough with  
navigating svn to find the latest release, is there reason to believe  
this has changed?

I guess I can monkey-patch Rails::process, with the aliasing-switcharoo  
trick, to first call the original Rails::process, and then call my own  
really\_really\_after\_initializers method?

Awesome, thank you, I’ll use 2.1 then, and count on the after\_initialize  
hook really actually being after the initializers.

Thanks for all your help, Fred.

That was changed in 2.1 (which is what I looked at before i wrote my  
previous reply)

sounds reasonable if you have to.
