How to change the status of a promotion at a certain time?

Question

Ruby on Rails

There is a Promo model and a table attached to it:

create_table "promo", force: true do |t|
    t.string   "name"
    t.text     "text"
    t.string   "image"
    t.boolean  "active"
    t.datetime "date",               limit: 255
    t.string   "image_file_name"
    t.string   "image_content_type"
    t.integer  "image_file_size"
    t.datetime "image_updated_at"
  end

In it , date is the date until which the promotion lasts. active flag, whether the action is currently active.
Now, on the main page, promotions are displayed if they are active and the current date is less than the end date.
I would like to make it so that when the end date is reached, the activity flag is automatically removed and the administrator is sent a message that the promotion has expired.
Please tell me how this can be implemented.
