require "active_support/current_attributes"

module Sidekiq
  ##
  # Automatically save and load any current attributes in the execution context
  # so context attributes "flow" from Rails actions into any associated jobs.
  # This can be useful for multi-tenancy, i18n locale, timezone, any implicit
  # per-request attribute. See +ActiveSupport::CurrentAttributes+.
  #
  # @example
  #
  #   # in your initializer
  #   require "sidekiq/middleware/current_attributes"
  #   Sidekiq::CurrentAttributes.persist(Myapp::Current)
  #
  module CurrentAttributes
    class Save
      def initialize(cattr)
        @klass = cattr
      end

      def call(_, job, _, _)
        job["cattr"] = @klass.attributes
        yield
      end
    end

    class Load
      def initialize(cattr)
        @klass = cattr
      end

      def call(_, job, _, &block)

          @klass.set(job["cattr"], &block)
        else
          yield
        end
      end
