Active Admin. How to assign the current user of a post when it is created?

Question

Ruby on Rails

I use Cancan to filter access:

scope_to :current_manager, :association_method => :blog_posts
  controller do
    private
    def current_manager
      unless can? :manage, :all
        current_user
      end
    end
  end

A side effect of this code is that although the administrator can see all the records, when he adds a new record, the user_id field remains empty. How can I assign the current user to a new record, regardless of access rights?

Answer 1

bafore_save in model...

Answer 2

It seems to me, all the same, it is better to override create
with something like

controller do
  create
    create! do |success, failure|
      if success
         # set current manager here

      end
    end
  end
end

It is not good for the model to know from the current user.
