how to automatically delete a record from the database in rails

Question

my produc

Answer 1

Create a rake task and run that rake task periodically. Something like:

delete_old_products.rake:

task delete_old_products: :environment do
  Product.where("created_at <= ?", Time.now - 3.weeks).each do |product|
    product.destroy
  end
end

You can run that from the command line with rake delete_old_products
