module ActiveAdmin

  # Member Actions give you the functionality of defining both the
  # action and the route directly from your ActiveAdmin registration
  # block.
  #
  # For example:
  #
  #   ActiveAdmin.register Post do
  #     member_action :comments do
  #       @post = Post.find(params[:id]
  #       @comments = @post.comments
  #     end
  #   end
  #
  # Will create a new controller action comments and will hook it up to
  # the named route (comments_admin_post_path) /admin/posts/:id/comments
  #
  # You can treat everything within the block as a standard Rails controller
  # action.
  #
