# Get all visits that have `ip` set and no `country`, `city`, `latitude` & `longitude` set.
# Schedule background jobs to process each visit and update it.
Visit.where.not(ip: nil).where(country: nil, city: nil, latitude: nil, longitude: nil).find_each { |visit| Ahoy::GeocodeJob.set(queue: Ahoy.job_queue).perform_later(visit) }
