ActiveAdmin Nested Namespace
This plugin allows you to register resources/pages with nested namespaces in ActiveAdmin.
Installation
Add this line to your application’s Gemfile:
ruby
gem 'activeadmin-nested-namespaces'
And then execute:
$ bundle install
Copy and paste these lines to config/initializers/active_admin_nested_namespace.rb
```ruby require ‘active_admin/nested_namespace’
if defined?(ActiveAdmin::NestedNamespace) ActiveAdmin::NestedNamespace.setup end ```
Get Started
Register resources to 2 different namespaces:
ruby
# /app/admin/site1/foo/bar/posts.rb
ActiveAdmin.register Post, namespace: [:admin, :site1, :foo, :bar] do
...
end
ruby
# /app/admin/site2/demo/posts.rb
ActiveAdmin.register Post, namespace: [:admin, :site2, :demo] do
...
end
It will generate routes like:
```
admin_site1_foo_bar_root GET /admin/site1/foo/bar(.:format) admin/site1/foo/bar/dashboard#index
admin_site2_demo_root GET /admin/site2/demo(.:format)

Configuration
In your initializers/active_admin.rb, you can define your own handler to the following methods.
- authentication_method
- current_user_method
- logout_link_path
For example:
``` ruby # config.authentication_method = :authenticate_admin_user! config.authentication_method = Proc.new do |name_path| if [config.default_namespace, :root].include?(name_path.first) :authenticate_admin_user! else “authenticate_#name_path.map(&:to_s)name_path.map(&:to_s).join(‘_’)name_path.map(&:to_s).join(‘_’).underscore_admin_user!”.to_sym end end
config.current_user_method = :current_admin_user
config.current_user_method = Proc.new do |name_path| if [config.default_namespace, :root].include?(name_path.first) :current_admin_user else “current_#name_path.map(&:to_s)name_path.map(&:to_s).join(‘_’)name_path.map(&:to_s).join(‘_’).underscore_admin_user”.to_sym end end
config.logout_link_path = :destroy_admin_user_session_path
config.logout_link_path = Proc.new do |name_path| if [config.default_namespace, :root].include?(name_path.first) :destroy_admin_user_session_path else “destroy_#name_path.map(&:to_s)name_path.map(&:to_s).join(‘_’)name_path.map(&:to_s).join(‘_’).underscore_admin_user_session_path”.to_sym end end
```
And in your routes.rb:
ruby
namespace :site1 do
namespace :foo do
namespace :bar do
devise_for :admin_users, ActiveAdmin::Devise.config
end
end
end
namespace :site2 do
namespace :demo do
devise_for :admin_users, ActiveAdmin::Devise.config
end
end
