                  class RunOnceTask < ApplicationRecord
  validates :name, presence: true, uniqueness: true
end

                  class RunOnce
  def self.call(name)
    return if RunOnceTask.exists?(name: name)
    yield
    RunOnceTask.create!(name: name, ran_at: Time.current)
  end
end

Sometimes you need a one-time maintenance operation outside normal schema changes. Use a small table to track “run once” tasks so reruns are safe and the operation is visible.
