Answer 1

There are different ways on how to handle this task. Check 2 options below.

Option 1 - whenever gem

You would setup a task using whenever which runs for example every 30 days.

1- Generate task as following:

rails g task posts delete_30_days_old

2- Create a ruby file in your application

# lib/tasks/delete_old_records.rb
namespace :posts do
  desc "Delete records older than 30 days"
  task delete_30_days_old: :environment do
    Post.where(['created_at < ?', 30.days.ago]).destroy_all
  end
end

Option 2 - sidekick and Sidetiq gems

# in app/workers/clean_posts.rb
class CleanPosts
  include Sidekiq::Worker
  include Sidetiq::Schedulable

  recurrence { monthly }

  def perform
    Post.recent.destroy_all
  end
end

and

# /models/post.rb
class Post < ApplicationRecord
  scope :recent, -> { where('created_at >= :thirty_days_ago', thiryty_days_ago: Time.now - 30.days) }
end

Since Ruby is about beauty, move the where clause to your model, where can reuse it.

These options will remove old posts from your DB and they will no longer be accessible by your application.
