ApplicationController how to execute code on each page

I tried to execute some ruby code on each page of my application! I putet the hole code into my application controller:

 class ApplicationController < ActionController::Base
 protect_from_forgery

 if Setting.exists?(1) 
 @setting = Setting.find(1) 
 else 
 redirect_to new_setting_path
 end 

 end

This somehow wont work! The strange thing is that when i put the hole code into my application html it works:

<body>
<% if Setting.exists?(1) 
@setting = Setting.find(1) 
else 
redirect_to new_setting_path
end %>

What do i have to change in my application controller?

ApplicationController is the correct place, but you should put your code in a before_filter :

 class ApplicationController < ActionController::Base
   protect_from_forgery

   before_filter :ensure_setting

   private

   def ensure_setting
    @setting = Setting.where( id: 1 ).first or redirect_to( new_setting_path )
   end
 end
