Suppose you have a Reminder model and you want to return x number of records at random. Something like this:

Reminder.sample # 1 record
Reminder.sample(5) # 5 records

Here’s how:

class Note
  def self.sample(count = 1)

This will produce two SQL queries. Something like:

Reminder Pluck (1.2ms)  SELECT "reminders"."id" FROM "reminders"
Reminder Load (0.4ms)  SELECT "reminders".* FROM "reminders" WHERE "reminders"."id" IN ($1, $2)  [["id", 114], ["id", 118]]
