Question

I have a periodic task that needs to execute once a minute (using delayed_job). I would like for Rails to automatically queue it up as soon as it’s finished loading, if one such task isn’t already present in the system.

What is a good place for me to run some code right at the end of the entire Rails boot flow? Someone suggested config/environments/development.rb (or other environment), but delayed_job give me ActiveRecord issues when I queue up jobs from there.

I consulted http://guides.rubyonrails.org/initialization.html, and there doesn’t seem to be a clear location for that kind of code either.

Is this kind of post-deployment setup to be done perhaps externally to my app’s code, maybe through rake or some other means? Any suggestions?

Thank you!

Regarding http://guides.rubyonrails.org/initialization.html, sorry, we’re working hard to rewrite it. For your problem, I would try with config.after_initialize in your application.rb

def after_initialize(&block)
  ActiveSupport.on_load(:after_initialize, :yield => true, &block)
end
