Defined in:
lib/vehicles/validators/vehicle_make_validator.rb

Overview

Drop-in validator: validates :make, vehicle_make: true.

Rails resolves the vehicle_make: key to this top-level constant automatically (camelize + "Validator"), so no registration is needed — requiring the file is enough. Forgiving (aliases/case/slug) like every other lookup, and defensive: blank values pass (pair with presence: true if you want them rejected), and any internal error degrades to a generic message instead of blowing up a form.

Pass allow_other: true to accept the "Other / not in the list" escape hatch (see Vehicles.other?) — pair it with Vehicles.make_options(include_other:) so the dropdown and the validation agree by construction.
