Question

How do I edit or override the footer of Active_Admin?

Answer 1

Between v1.0.4pre and v.1.0.5pre, the previous method of overriding Footer#build no longer works well, and the new API is

ActiveAdmin.application.footer = proc {
  ...
}

Answer 2

If all you want to do is change or delete the 'powered by' message, what you can do is change its value in a locale file. Example, edit config/locales/en.yml

And use something like this:

en:                                                                              
  active_admin:                                                                  
    powered_by: "Powered by hamsters"

Why this works:

The default locale for a rails app is english, the en locale file.
