Active Admin + Authlogic Integration - Rails 3.2

Question

Does anyone know how to integrate Active Admin with Authlogic (I'm using authlogic_ldap_authenticatable gem to authenticate to AD)? I know Active Admin uses Devise, so what changes should I make to Active Admin for it to work with Authlogic? Thanks in advance.

Answer 1

Note: I used Rails 3.2.8 and Active Admin 0.5.0 when I did this.

Here's one way to do it:

1. First, update Gemfile by adding gem activeadmin, and run the rails generate active_admin:install. These are as instructed in the Active Admin README.

2. Typically there's already a User model that uses Authlogic, and if you plan to use that, remove all files for the new Admin User that Active Admin has generated by default:

   • db/migrate/*_create_admin_users.rb (migration file)
   • app/models/admin_user.rb
   • spec/models/admin_user_spec.rb

3. Remove Devise-specific files:

   • config/locales/devise.en.yml
   • config/initializers/devise.rb

4. Remove the Devise reference in config/routes.rb.

5. There's a generated file app/admin/admin_user.rb. You can reuse it by renaming the file to user.rb, register User in it instead of AdminUser, and remove indices on columns specific to Devise. Or, you can just delete the file altogether, and just create your own from scratch.

6. Update the following in your Active Admin config (see config/initializers/active_admin.rb):

   • config.authentication_method
   • config.current_user_method
   • config.logout_link_path

   The default config.authentication_method is :authenticate_admin_user. Set it to whatever before filter method you use for requiring an admin user, e.g. :require_admin. The default config.current_user_method is :current_admin_user. A typical Rails app that uses Authlogic might have a :current_user method for this. And config.logout_link_path should be set to your path for logging out, e.g. :logout_path.

You may need to modify these instructions according to your case.
