If you need an array of one or more model attributes for your relation, then you can just use ActiveRecord::Calculations#pluck.

From the docs:

Person.pluck(:id)
# SELECT people.id FROM people
# => [1, 2, 3]

Person.pluck(:id, :name)
# SELECT people.id, people.name FROM people
# => [[1, 'David'], [2, 'Jeremy'], [3, 'Jose']]

And there's more what you can do.

Relation has to_a method, which does exactly that. It is used internally for methods like any?
