Overview

Thread-safe current user context using Rails CurrentAttributes.

This class provides a thread-safe way to store the current user for auditing purposes. It leverages Rails’ CurrentAttributes functionality to ensure proper isolation across threads and requests.

Examples:

Setting a user

Whodunit::Current.user = User.find(123)
Whodunit::Current.user = 123  # Can also set by ID directly

Getting the user ID

Whodunit::Current.user_id  # => 123

In a controller

class ApplicationController < ActionController::Base
  before_action :set_current_user

  private

  def set_current_user
    Whodunit::Current.user = current_user
  end
end
