audited gem: switch between current_user and current_admin

Question

I am using the gem Audited, for logging any changes done to the model. However I faced a problem, when trying to distinguish changes that are being done by normal user and those being done by Admin. I somehow need to tell Audited to user current_admin method, when current_user is nil, but I can't think of way to do it.

Answer 1

You can specify the method the Audited gem uses to assign user. The relavent bit from the README is below:

Current User Tracking

If you're using Audited in a Rails application, all audited changes made within a request will automatically be attributed to the current user. By default, Audited uses the current_user method in your controller.

class PostsController < ApplicationController
  def create
    current_user # => #<User name: "Steve">
    @post = Post.create(params[:post])
    @post.audits.last.user # => #<User name: "Steve">
  end
end

To use a method other than current_user, put the following in an intializer:

Audited.current_user_method = :authenticated_user

---

In your application_controller.rb you can add a method to check for the nil value in current_user

def current_user_or_admin
  current_user || current_admin
end

And in an initializer, something like config/initializers/audited.rb add

Audited.current_user_method = :current_user_or_admin
